Sometimes I wonder if it's better to have one major fail rather than a thousand little ones. I'm not even in the same solar system you are but feel your pain. Keep knocking them down. Want to see that 7 second time slip!
 
Everyone says you shouldn't show up for an event with a new build and untested car and I couldn't agree more. But what do you do at this point? We spent 20 months working on this thing almost non-stop, I paid the race registration booked the hotel rooms, its time to go!! And we are going to do our best to make the most of it.

Tech Day!
If you get a chance to attend this event this is the best day to be there as everybody is still in it lol! Just to see all the really cool cars, it not like a competitive class race where the cars are mostly the same (Fox bodies and S10s), there is a little of everything there and it is all really cool.

We got there early and had to swap over to street tires in order to tow the trailer to tech. We were in line early which we needed to be so we could be ready to roll at 2pm when TnT started and hopefully after being in Florida for a week we can get the car down the track!!

Tech went pretty smooth but man were they through! That was by far the most through NHRA tech inspection I had been through but we passed for a 7.50 cert and got into A group. The car is actually cert to 6.50 but my license is limited to 7.50 but either way being in A group as its advantages! The keypad worked through tech along with all the lights on the car and the trailer and nobody said anything about my horn/starter combo switch lol!
0128241158.jpg

At this point we are as ready as we will ever be to make a pass but we still have no idea what the car is going to do going down the track. The decision was made to just do a 300' pull which is what I did and it went really well, no issues car ran well, hooked, went straight, everything worked burnout went well, Line lock, t-brake, bump air shifter, even tossed the laundry and the chute opened. All good, we cleaned a few things up on the datalog, re-packed the chute and waited for the 2nd pass.

I hung out with Zack Meyers and Snot Rocket V1 while waiting to make a pass, very nice guy and family who really dug the GN which was cool because his build was next level compared to mine. This wasn't snot rocket V2 which is Brett LaSalle who won the event. Zach's car is more street car than race car and a true 6 second ride really bad ass.

Next pass we decided to run pull run the whole track and see how the car handled. I was running on WG spring at this point and this is pretty much as slow as the car will go!. Everything went smooth and the car went 9.90@135 on 13psi. Not to shabby for WG spring and spot on for what it made on the dyno for WG spring so we feel like we have a pretty good handle on the tune up.
Burnout.jpg


After reviewing the datalog we noticed a problem with oil pressure dropping off
Oil Pressure.jpg

The yellow trace is oil pressure as you can see it nose dives going into 3rd. You can see the oil temps go down as the oil accumulator is pushing oil in it as pressure drops which is pretty cool. Oil pressure never fell lower than 40psi so nothing was hurt. This also wasn't exactly a new issue either and have been dealing with oil pressure and control issues since the first pull on the dyno. Initially the issues was way to much oil pressure and we were also pushing oil past the seal in the turbo making a mess so to back it down I had been losing the bypass spring. The last pull on the dyno it everything seemed right but pressure was still a little high and I backed it out even further and my thinking was the spring was to lose and the bypass valve may be floating around.

What about cylinder #3? Plug still looks like crap, I am getting some smoke on start up but no more than the average import guy who I am racing against in the Sick Freaks class lol! Absolutely ZERO smoke or issues going down the track as soon as you bring the motor up on the brake it totally clears up. So the plan is just to keep an eye on the #3 plug and change it after every pass We were hoping to get a 3rd pass but Steve Morris blew a trans line, hit the wall and shut the track down so the day was over. I guess I'm not the only one! At least I didn't catch on fire and hit the wall!! We were standing there when it happened felt bad for him too. Oil downs and track shut downs were a serious issue for tech day and day 1. Here was my trans line failure and oil down Friday night at Cadillac Attack. I never saw it till 3/4 track just knew the car was out of shape and lifted. I was very lucky no fire or crash.
Track Oil down.jpg


The next day was RACEDAY and we are feeling pretty good at this point. To follow up on the oil pressure issue we cut the oil filter open which was spotless so we then tightened the bypass a few turns and got ready for our next TnT pass which was also going to be our first official race pass! I put 18psi of dome pressure in it which should give us somewhere around 20psi of boost. We left the 2-step at 4k which is REALLY soft for this car and it is producing easy high 1.40s which is fine for now. Everything we are doing now is also streaming live on the internet!


Easy peasy, everything going as smooth as it could on the track. 19psi 148mph not to bad, the tune up is also super conservative but then again we never planned to run the car at 19psi of boost! The oil pressure issue did improve with tightening the bypass valve. We can see the oil temp decrease with the opening of the Accumulator and pressure never drops below 40psi so we are not super concerned. I am pretty convinced it is a bypass issue at this point. Still no one likes to see oil pressure do goofy shit like that in 3rd!!

The track went hot at 9am and being in A group I was in the first run group with all fast cars and people with their shit together WAY more than ours was! There are a lot of cars at this and the first day is the day most of the ones that won't finish get weeded out. Problem is most of the weeding happens on the track and it makes for a REALLY long day.

At this point we had a big decision to make. The drive to Bradenton goes out to the Atlantic side across the middle of the state through a swamp to Bradenton. It is going to be a 5-6 hour drive so the earlier we get on the road the better and in hindsight the best decision was to turn in the 9.40 slip and get on the road.

But NOOO we are now racing AND we at least want a fighting chance at winning the class which after all is what we came to do!!! The top guys at this point are a Gen 2 Supra running 8.70s and a 70 Chevelle with a duramax running 8.90s and a Honda Civic also in the 8.90s. Mark Huber was there with his 7 sec SVO Mustang but was on the struggle bus, along with another bad ass GTR that was also a new build and was along for the struggle bus ride but making progress. All we had to do was turn in an 8 sec slip to be in the hunt so we decided to stick around and wiat for a second pass.
0129241404_HDR.jpg

And wait we did, till about 4pm. Up to this point the car has been working really well and with the exception of a puff of smoke at startup it has been running really well. For this pass we put 25psi on the dome which should be close to 30psi of boost and about 1000rwhp from what we saw on the hub dyno. I also put 200 rpm on the 2-step which is probably going to still be a really soft 60 but should still put the car DEEP into the 8s.

I fired to car up and uh-oh its smoking bad, like REALLY bad. I pull into the lanes the track official looks at me and says verbatim "you better not fucking oil down the track"! We get up to the gate and are first in our lane and now having a conference with the rest of the staff who is obviously concerned. Ray and I decide to abort the pass, the car is definitely smoking WAY worse than it has since we started this adventure and 30psi of boost is not going to help whatever it is causing the issue. We pullout of the lanes as the staff applauds our decision and we head back to the pits. We go over the car again, check the plug, test a few things and try to bring it up on the 2-step and its just billowing smoke. We briefly entertained the idea of limping it to Bradenton tearing it apart there to find the problem then decided against since if we had to sit in traffic with it smoking like this we would die of asphyxiation. Plus it was late in the day with a 5-6 hour drive ahead of us in an untested car we have driven maybe 40miles. It's one thing to have a bunch of issues at the track but a whole other world of pain to have issues at midnight on the side of the road in the middle of a swamp in Florida!! WIth the smoking host of other small issues we need to address so we decided to call it. It wasn't an easy decision but it was the right one. We loaded up and started heading home and discussed it for the next 18 hours lol!

Next up post race analysis, solutions and whats next!
 
Hey Chris. Met you and Ray at OSW. I was across the road in the grass pits from you with my buddies in the green 4 door Nova. We ran Sick Week.

Killer build on the car!! New build blues for sure but great looking car that I’m sure will perform once the bugs are worked out.
Thanks, I remember, how did your buddy do with the Nova?

Thanks, Believe it or not most of this is normal stuff for a build like this. Knock on wood we really have avoided having any of those major issues.
 
Thanks, I remember, how did your buddy do with the Nova?
Met our objectives of no failures and had an absolute blast. He ran in bullseye class and we just went out and ran the car with no real intent of competing. Think he got 3rd on the final day.
 
We had a long ride home to discuss our decision to stop which was hard when we know the next pass on the car it was going to rip! The bottom line was the car wasn't hurt at this point, we didn't know for sure what all was wrong with it and if we did hurt it we could be out for the rest of the race season. So we lived to race another day!

Once we got home I had the rest of the week off work to get stuff done which was nice. I pulled the motor and took it out to my machinist to start pulling it apart. The issue was immediately apparent this time.
Hole.jpg

Yes that's a giant hole on the pushrod side of #3 intake port and this hole was not there when I had the intake off before we left. That hole was likely a previous repair that was seeping oil and came apart after the 9.40 pass which explains why the oil issue got so much worse after that pass.
_part-2000000000039493_.jpg

At least it is an easy fix. The head is already welded and I should have it back early this week and hopefully back in the car next weekend. I still have a lot of little things that need attention and a punch list to knock through but it is mid February in Ohio and I have plenty of time to work through it.

The oil pressure seems to be the bypass valve as expected.
0215241413.jpg

The o-ring for the bypass valve was leaking and I need to find a lighter spring for this pump. It is a Gambler pump which they are no longer in business. The new Fluidworks pump from Motion looks like it is the same dimensions and I may use it if I can not get this one to work.
0215241628a_HDR.jpg

Another thing that could be causing the oil pressure issue is the oil pan capacity which in my case is kind of small at 5 qts. I added a Moroso accumulator to this car a long time ago for this reason and kept it with the update. I also added an electric valve I now control with the Holley/Smartwire that opens the valve automatically at 3500rpm and closes it at 3450 so it is always active. The accumulator is definitely opening since you can see the oil temp go down when it does. WIth the accumulator set up I have close to 8qts in the system.

I am not convinced this is the issue either. If I am sucking the pan dry I would have at least 5 qts of oil in the valve covers with a vacuum pump sucking it out the 2 -12an ports I have on each valve cover. That would completely fill the breather tank which had maybe 8 oz of oil in it from the whole weekend. Even with the hole in the intake port I still had pretty good crankcase vacuum. I also have additional drains from the back of the heads directly to the oil pan.

I am in the process of building a new pan for it with more capacity. As a matter of fact this pan was originally made by CAS and I have the engineering drawings for it. I am having them re-done in auto-cad and will increase the sump capacity. Ray is also going make several so if anyone is interested in an oil pan with a matching engine diaper we may have something this spring.

What's next? Registration for Drag Week opens on the 24th and I am going to try and get in. The race is in September which gives use all spring and summer to finish sorting this car out. We are super excited about getting back out and planning to take it to Bowling Green, mostly for testing. I may do Steet-nYeet in November and definitely plan to make another run at Sick Week 2025.

Everyone says you shouldn't show up for an event with a new build and untested car and I couldn't agree more. But what do you do at this point?
Everybody is right.
A very fast car requires testing not only to get a number but also for safeguarding your investment😉
We like shakedown passes to grab data even if we cannot get the number that day.
be safe and good luck.
 
Doing drag week?
That is the plan as of now but this F'in car has a mind of its own. It has been an on going nightmare since Sick Week.

I just put the back up motor in and fired it Sunday after a crank gear broke at Heads Up Hustle and made a mess of the engine at the end of July. It left us stuck in the hood on westside of Lansing for 5 hours on a Friday night!

Good times!

Car looks bad ass:cool:

This is a great thread, so much info here on the insane amount of effort it takes to build a car like that.

Keep this thread up to date!
 
What a story, makes for good reading. You definitely know how to keep us wanting more and keeping us in suspense (why you). Hope you do well at your next event. And Chris, your being to humble. We know you left for a bit but I think most on TB.com know who you are.

An article on Chris's GN for you guys to read:
Sellers Remorse Leads to Re-Claiming a Buick Grand National and Prepping for 7-Second Runs on Sick Week 2024 — Sick the Mag

Chris it's Mario from NY, long time no see. Your story could have been a little different. This post and article would not be if you would've accepted my offer for your car (I believe in 07')😁, when I came to your house with cash, met your demands and you still would not sell it to me, remember.. LOL 😂 Well i'm glad you didn't because I love the reunited story and can't wait for the next follow up. The car looked awesome then and now on a different level! CONGRATS & WISH YOU THE BEST!!
 
Well we made it to Hot Rod Drag Week and finally had some success!
20240921_093136.jpg

We averaged 8.93 and handed in an 8 sec timeslip at every track. The car made the 900 miles of street driving with out an incident or issue and really performed well in that respect. The only downside is the car is stupid slow lol! Honestly it hasn't been this slow since 2006 so we still have some work ahead if we are going to live up to the title of this post!

I haven't posted much of an update since Sick Week. The crack in the intake port ended up being a much bigger deal to fix than initially anticipated the entire side of the intake port had to be taken out built up with weld and re-machined. I finally had the car back together and running at the beginning of May. I was preparing to take the car to the track and finally start testing it when it was idling on the lift and made a horrendous noise and died. After some investigation I found it dropped an exhaust valve. WTF
0510241851_HDR.jpg


Seriously, the heads have a high end Titanium intake valve and cheap SS exh valves. I was incredibly lucky in that the exh valve didnt drop all the way out and when the piston came up and hit it the motor stalled. I was lucky nothing was damaged. I ordered all new valves from Victory including new Titanium intake valves with the beadlock retainers.
0510242152_HDR.jpg


In the little time I had the car running before it dropped a valve I did get a chance to do some 2-step tuning and found the internal dump valve in the trans was not working correctly. I also had to high of a charge pressure while on the t-brake. I pulled the trans and took it to Vince Janis who tore it down and sent the valve body and pump back to Lonnie at Extreme Auto. Lonnie made a new me a new valve body with an internal dump and also added an external dump to the trans.

Vince got everything back together for me I got everything back together just in time for the Heads Up Hustle in Michigan. I had this on the schedule as a primer for drag week. It was a 3 day event driving between Milan and US131. Again we are going to a race with zero testing.

I made two really easy hits on the car at Milan which were really slow in the 60' but we weren't concerned we were way more concerned with the 170 mile drive as we haven't driven the car more than maybe 10 miles up to this point. We swap the car back to street get loaded up and while pulling out of the track we notice the alternator isn't charge. This is a new alternator we put on just before we left since the powermaster I had on the car for 20+ years decided to crap out when we were loading the car. That is 2 alternators in 24 hours. We were able to track one down at an O'Riely's distribution center and by 6pm that evening we were finally on the road. We actually celebrated making it out of the parking lot.

The drive started off a little rough as we had a small wiring issue to deal with and we also had to dial in a pump E85 tune. After the first 10-15 miles things got better and things were going well. We made it to the first check point and were feeling like we might actually make it
20240726_204636.jpg

It was 10pm on a Friday night and we were a quarter mile from the second check point on the west side of Lansing Mi when the motor made a noise we knew was going to be bad. We coasted into the parking lot of the Carriage House Apartment complex and quickly met by a few of their finest residents with a Yo Yo I can't believe its a F'in Grand National. Its my F'in dream car!. I wish I could have gotten pic of the look on Ray's face. We were now stranded in the hood on a Friday night with the only business around being a Liquor store next door. Good times. I called AAA they were sending someone right out. The race coordinator came down and picked up our trailer while we sat and waited for 5 hours for AAA to pick up the car and tow it back to Milan. They could not get a towing company willing to pick us up so I had them tow the car and us 4 miles down the road and drop us in a hotel parking lot that was next door to an Enterprise Rental car location. I got 90 minutes of sleep and jumped in the rental and drove Ray the 95 miles back to Milan to pick up the truck and trailer and had to haul ass back to the rental car company since I only had 3 hours with the car or I was going to be charged with the rental till Monday since they closed at noon. I made it with four minutes to spare!

Once we got everything back to the hotel at Milan I pulled a valve cover and found a couple of valves stuck open and figured it ate a lifter or timing chain. Either way it was not going to be good. When I got the motor apart I found a broken crank gear. I have no idea how that happened and my machinist even said that was a new one for him. There was damage to the keyway on the crank and the rods smacked the camshaft ruining it. While it is all fixable it was going to be faster to put together my back up motor if we were still going to make Drag Week

20240802_112219.jpg

My brand new inconel exh valves from Victory and one Ti intake not looking so good
20240902_081658.jpg

John Nguyen came through on a set of Rods and a new Billet roller cam from Bullet. Despite having a bunch of issues getting the new motor together I was able to get the motor together and back in the car in time to actually go testing the Friday before we had to leave. We went to a track rental at QCR made 5 hits on the car with two full track passes. The last run was an 8.95@155 with a 1.36 60' leaving at 5k and 15psi of boost which was REALLY slow with a 5k launch and 15psi it should have flipped the car on its roof! The converter was obviously an issue. I ended up getting a new stator for it that week and got it in by Saturday just in time to pack and leave for Drag Week. So off to Drag Week we go untested again with a new stator in the car hoping that will fix the issue.
image25818.jpg
 
We got the new stator in the converter just in time to load the car on the trailer and head to drag week completely untested once again but we did have tech day to make a couple of test passes.
20240915_122448.jpg

We made a few hits on the car and the new stator change didn't change much of anything and actually made the car a touch slower in the 60 when comparing DS speed curves. We packed up and got ready for Day 1, while we didn't expect to avg 7's at this point we did hope to be at least in the 8.50 range maybe a little faster, especially based on the cars prior history and performance.

Our new goal or actually our original goal was to just finish the event. If we can hand in an 8 sec timeslip at every track we felt that would be an accomplishment for the Buick V6 world so that is what we set out to do and on day 1 we were one and done and packing up to make our way to Indy.
20240916_105208.jpg

20240916_112159.jpg

The car did well once we were on the road, actually it was way better than we thought.
Checkpoint 1
20240916_141302.jpg

Checkpoint 2
20240916_162640.jpg

And 230 miles later we are at our hotel in Indy. While everything went well it is exhausting to drive this car that far. We really need headsets and more comfortable seats. Solid mount aluminum Kirkeys in a solid chassis with all solid joint suspension is NOT a very pleasant ride!
image25893.jpg


Day 2 at Indy. I raced TSO here once before with this car in 2006 at the Buicks at Indy event John Camberlin hosted. I think the car was faster then lol! The track was a little sketch but it went smooth for us with another one and done pack and go.

20240917_110945.jpg

Of all things I was having issues with it was my parachute. I ordered a new pilot chute from Summit who had it at Indy the next day. We had to stop at NHRA HQ to pick it up
image25926.jpg

On the road again
20240917_165203.jpg


The first Checkpoint was Bryant Goldstones shop which was packed when we got there. On the way we also met up with our friend at some remote gas station off the beaten path getting E85. We did the rest of the DW rides with him which it is nice to ride in a group.
20240917_161949.jpg

Checkpoint #2
 
Checkpoint #2 was Lane Automotive. It was late in drive and Ray just jumped out to snap the pic and we kept rolling after that.
20240917_181438.jpg

And 290 miles later we were in Martin Mi. This was the longest drive of the event and a real marathon in a car like this we were happy to be done with this called it an early night we were tired and I forgot to take any pics.

US131 is a REALLY nice track and those guys REALLY know how to prep a track. Ray and I agreed the next time there is a cool event there we are going to make the trip up to race there. There was a fog delay early that eventually cleared and we made another one and done pass.

20240918_121425.jpg

We tried small steps in putting more power to the car and trying to leave harder but it wasn't working. If we launched with 10psi it went 1.40 if we upped it to 15psi it would go 1.35. and pretty much ran 8.90s with 25 or 31psi. We definitely have issues with the trans and/or TQ converter but have a few tricks left we can try that we are waiting until we get back to NTR to try.

Then it was off to Milan which was the shortest drive of the week but they added to it for the checkpoints and it came out to 190 miles still.
Checkpoint 1 we stopped and ate at which was pretty good and they had thier own homemade root beer
20240918_140330.jpg

Checkpoint 2
20240918_175349.jpg

And 190 miles later we were in Milan Mi for Day 4
20240918_185621.jpg

Day 4 of Groundhog day, we are actually pretty shocked we made it to this point and how smooth everything was going. Milan was more of the same we had another fog delay in the morning and I tossed the laundry early on this run but it really didnt effect the ET so we were one and done again and actually on the road back to Columbus!!
