Is that motor getting machined the 109 block I sent you? :cool:

Sorry to keep hijacking your thread Dave.

No Bob, the one I got from you is done. I didn't know if I should post any pics of it since everyone will howl looking at the paint job. :smile:

Personally I'm sick of our dark engine compartments...they're so hard to see any bad stuff going on. So I painted your block white. (And I looked for white spark plug wires but couldn't find any.) Pic attached....be gentle on me guys.

You're right about the picture! I hope its fast cause it sure is ugly! haha Good luck with it. I will send you a can of black paint for free if you fix it:p
 
Not when your revving the engine to 7500+rpm. The boost helps the rings seal even better if the bores are round. I meant to include compression rings also on that post. But got ahead of myself.

Boost will not help oil rings seal better,only top rings. The wider the oil ring package is the more stable they will be. Any amount of oil in a combustion chamber is no good. The combustion process is happening in the ring lands and between them too, any oil in there will cause detonation and flutter the rings causing the rings to lose seal. If you lose ring seal you won't be able to transfer heat into the cylinder wall. More than 50% of piston heat is transferd thru the rings to the cylinder walls. If you lose ring seal you'll lift a ring land or burn a piston. but to each their own.
 
Dominic,

I am with you on what you said.

There are a few ring designs though that will seal better under boost, dykes style rings do and if the piston is gas ported it will also generally seal tighter under boost.

The dykes rings are actually a great turbo ring as they are very low tension but get pushed out under boost.

David,

I, like you am a fan of the dykes ring, just like you said, "a great boost ring". I am an engine builder/performance specialist by trade and i have seen very few rings work as good as a dykes style package.

From what i have read you have a killer combo and it sounds like a beautiful car too. Best of luck to you and your goals with your Buick, i am certain you will meet them without trouble. Please keep us updated on your progress.

Dominic.
 
turbo2nr,

Haha, don't tempt me! I was SO close to dropping one of our 4 cylinders in this car, it's a running joke at our shop that I should just do it. IF I put that same engine in this car with a TH400, I'd guess I could run 8.50's, maybe a little quicker. I just can't do it. The car is still too nice, even with all the crap I am taking off for TSM. It just wouldn't be the same with a Mitsubishi 2 liter in it. It would be fast as hell and never break but wouldn't be right.

Besides, I have to prove to myself I can build this car with the 109 block in it.

Hell my daily driver on radials runs 9.97 at 142 mph, drove it to and from the track watching the double DIN TV! Take my kids to school in it everyday in the summer.

Here's what I drive everyday when the weather is nice.

This car will bust 150 mph this year and I hope to do it on E85 gas. I want to run 150+ on radials and then I am done with it, not going to try and make anymore power with it. Just drive it. Great car.

I want to finish it so I can concentrate on the Buick and of course the other black car:)
 
I'm sure Billy Anderson must be turning some serious RPMs with his destroked 209ci 109 TSM motor....


yea i think he turns 8000.. but i could be off a little :biggrin: ..

Also, welcome Dave to the Buick world.. i use to follow your motor builds and Extreme's, when i owned a Conquest TSI :) back in the day..
 
Thanks Nordy. It's more of welcome to TSM though, I've been around Buicks for a long time. Just haven't attempted to use my personal car to compete with.

Few years ago I was driving Ron Luman's TT Buick, we were winning or qualifying number 1 at about every race we attended. That was a great car, I ran 7.58 in that car.

I've had this WE4 I am turning into the TSM car for I'd guess about 6-7 years. Dad's been building/racing his since 1986-87.

It's a sickness, I'm down with it. No matter how mad I've gotten at this car over the years I've kept it.........can't say that about a lot of the ones that have been "given" away.

Looks like any input to actual RPM limits from fellow TSM guys is about over.

Off topic is better anyway. Believe half of what you see and none of what you hear;)

BELIEVE THAT :biggrin: .. i saw a conquest tonight :frown: it made me miss my old 89 TSI (which was black).. it was a strong running car.. i had a 20G on it and custom port fuel injection.. "top end" (i think that who it was) Cam and ported head.. i just loved how it looked with polished stock wheels..

weren't you running 9's in talons back in 1995??

I've read before about Buschur's Buick background, it's good to know there will be one of them running under his name. I used to have a '90 GST, my tire burner, with just one call, some questions and a mail order my car was way different. I had a terrible tire-smoking problem, I was doing 101 at the traps with an extremely fast 15.6 timeslip :eek: , please guys dont try to run this fast, its dangerous, but it was my fault, i never even dropped an LSD. But in the street it was other thing, I smoked 12 second cars all week long. I really loved that car. I know this is a great addition to an already excellent family here at our page.

Dave,
I am not going to provide any input on RPM. :cool:
From your results, you know what you are doing.
From your writing, you sound like a class act, something we can never have enough of.
From your determinitation, you will suceed. (I LOVE and admire any level of determination that can seperate the "men" from the "boys" :biggrin: )
From me, BEST OF LUCK!
 
nordy, the Conquest makes a great race car. We put a 4 link and 12 bolt rear in an '89. Bolted up a Powerglide to the 4g63 (2 liter Mitsu engine we build) and on a 26"x10.5" slick the car ran 8.61 at 158 mph. Killer car. We had the best time running at NRP in the Outlaw Street Class. The class was FILLED with nothing but V8's. We qualified at every one. Every week some cry baby would protest us for something, we were always legal but they just could not stand that 4 cylinder making the class! haha

joelos, hard to remember back to 1995 but I don't think we had gone 9's by then. 10's for sure. I think the first time we put a 4 cylinder in the 9's was about 1997-98. It's pretty freaking easy now, then it took a race car, now my daily driver does it on radials:smile:

jerryl, I'd be glad to hear what you have to say about RPM. That's what the thread started out as after all. Thanks for the kind words.

I was at a good friend of mines house today. He is very big in the Buick community. It was very interesting talking with him. I have always just looked to my dad for guidance on the Buick and just spent the money. There is very few parts I ever bought for the car without asking him what was next. I bought wheels/tires and the full HR rear suspension as I wanted a certain look and the car to actually handle too. Other than that my Dad's been the brains behind the car. I wanted it to run 11.50's when I first bought it blown up. He built the shortblock, guided me through what I needed. The car ran 11.2 at 19-20 psi, had the fuel system on the car not gotten trashed from whatever trashed it, it would have ran 10.70's with ease I think.

I am kind of doing this new build on my own. Still asking my dad some questions but taking my own retarded direction with the car. He has a freaking gorgeous 13,000 mile WE4 he bought new. Has never so much as drilled a hole in it that didn't belong. His has run 10.80's quite a few years ago. I tuned the FAST that is in it now and I'd expect to see it go much faster than ever before now.

I am absolutely geeked about this build on my car.

Finished up the complete fuel system tonight. Came out better than I expected. Metco spare tire well fuel cell. BTW, the provided brackets suck, throw them in the garbage. I made new ones out of stainless strap, like what they provided but that actually fit. I used -8 AN lines to and from the new Champion rails. Aeromotive pump/filter, fuel lab regulator. I hate anything that doesn't look "clean", this came out pretty darn clean.

The car is going to look a ton better with a new wiring harness in it.

Plan to wire the fuel pump tomorrow, fill it with gas and check it all for leaks. I hope I have my turbo this week so I can fire the engine. PTE 71 Qtrim.

I am building a custom 3.5" turbo back for the car. Super light weight, same stuff we use on the EVO's. Using a Tial 44mm wastegate on it.

Also putting a Wilwood master cylinder on the car. BTW, anyone looking for a good complete master cylinder and such? I have mine I took off, worked fine. I hear it might be worth a little cash;)

As soon as the car can be moved I will get it up to our shop so my brother Daniel (owner of our service department) can install the spool, 33 spline axles, yoke, rear diff studs and the cover/girdle, 3.5" aluminum driveshaft. Then off to Janis transmission for the transbrake.

I have the block at the machine shop being cleaner/rust stripped so I can get a good paint job on it. (black not white! haha) I have awhile before I need the engine.

I want to get the rest finished first and get good basic tune in the BS3. I had the Moton's in the car before so I'll need to re-tune the car on the 95#'s that I put in it now.

This is some fun stuff. I've had the car for 6-7 years and have never done much to it myself. Always pawned it off on my dad or brother. I'm having a good time with this...............
 
Dave glad to see your doing something with that car.Will the car be ready for bowling green or norwalk???
 
What can we expect

David -

What can we expect from you as it relates to your business and Buicks. Tym got me hooked years ago and since then I've been up that way all the way from Miami, Florida to have him and your team do work on my '93 GSX. I went with a stage I block and stage III head years ago. I have since upgraded to an AEM stand alone which I had Swytzer install.

But, it's alwasy been great doing business with Buschur a class act. Can we look forward to you offering another choice as it relates to Buick parts once you get your WE4 competitive? Or am I looking to far down the road, I have been working on my WE4 for over a year trying to pull something together that will make the local supra crowd sorry they ever looked my way.

Thanks for the dialogue always good to learn more about the technical side of these cars.

turbo6mike,

The car should be ready by Norwalk, I don't see why it won't. The new shortblock I am doing for it may not be done but the car itself should be running/raceable within the next few weeks. I finished the fuel system today, wiring and all. Not a single leak, I figured I'd atleast have a drip. So now a turbo and a master cylinder and the car will be running/driving. I was at Vinnie's this weekend, he's gonna get me in right away for the brake and to double check the trans.
 
madturbo,

Please don't ruin this car with wanting me to make parts for it! The last hobby I loved turned into a business and it sucks most of the time now. We have always sold turbo Buick parts through the shop, my dad handles it mostly. We don't advertise it. I have no desire to make anything for the cars. There are enough other people doing it.

The only thing I am interested in doing is tuning the cars here on the dyno or the track. I've offered our dyno to Red probably 20 times but he heads off to Michigan anyway. I believe we have a superior, actually I know we have a superior, dyno to a Dynojet. Tuning here gets the cars dead on for the track. I tune a ton of standalones now, that's all I want to really "branch" out to with the Buicks.

Cool well I look forward to you adding to the already great dialogue that takes place here.

You may have said but what are you using for EMS??
