billet 67 discussion

[KevinB]

Before I hand over my hard earned money for a new turbo, I need to know if the billet 67 is working for anyone. I know the billet 71s are doing good but have yet to see a 67 on a Buick v6 lay down the number. The Turbo will be going on a 6500 rpm 234" engine with good heads and everything in-between. This engine ran great with a 70 gtq.
Anyone have any luck yet? The import world has had success but has the Buick world?

Not me! I have contacted Precision and they told me they would have Patrick call me back. That was a month ago. Then while doing my search for information I seen Hartline has PM'd people about it but didn't share the results. I did see a post where it said it would not make over 850hp in a Buick application. The vendors say 900hp conservatively rated. I saw that after my purchase. I was tickled at that because there is no since in crying over it now. I had a 70 Gtq H cover ported shroud .85 housing. We all know how the thigh can get down. Sold that and regret it. I expected quicker spool, and same HP at less boost. Or even the same. The 67 spools just a hair faster, but it takes 3-4 more psi to match the trap mph. The tune is even 10.8 a/f vs.10.2 a/f. I told the guy from Precision I'd meet them at the track and let them check it out but didn't get a response to that either. Now I wish I had of got the 71. But at least I can still run the THE class when I slow it down even more with the e cover. I may take it to the track again next week to see if I can get it to show and prove. I'm not too mad because I didn't shell out a lot since I sold my 70, but it is not what I expected it to be.

Well - here are some track results - sort of..........I've been messing with the big car too long - this street car stuff is tricky!

Took it out to our local crap hole of a track (1/8th mile) armed with good fuel and MT drag radials. Basically the only thing I have to report is that it ran 99mph in the 1/8th with only 20psi. Launching off the footbrake at 2# yielded a smoking hot 1.69 60ft time with a 7.14 et - this was with some spin and only 20psi. Any attempts to launch with more boost resulted in tire smoke. Tried turning it up to 25#s down track - as soon as it hit the tires went up in smoke. 25#s and up is where this turbo makes hay - I'll have to mount some slicks and get some boost controller advice from Cal and try it again later. Bottom line is that there is no doubt this is a mid to low 10sec turbo on a full weight GN with supporting mods. With a decent launch it would have run around a 10.80 in the 1/4 - at only 20psi with a mild tune in the XFI. There is no doubt this turbo will run mid to low 10s in a full weight car.

As Murphy would have it, the Powermaster died just as I was pulling into my driveway at home. I've got to get to work on getting the big car put back together for BG so this project will have to be continued at a later date.

Seems like pretty good results for a baseline to me.... Mine has the same turbo and is going through the final steps before we fire tonight. Dyno after that I'll post #'s ASAP.

It will only benefit you if have you have the rest of your combination set up for it. Just like the 71 billet, I have seen great benefits from it and I have also seen others bolt it on and expect it to be the "magic pill" and not go any faster. This is usually because they don't have a clue what it really takes.

FWIW: I have customers who have run high 9's with the cast 67.

 

[SGRIM]

We have one on one of my cars and have installed another. I think they are excellent. However like Cal said if the combo isn't right for it, the effects will not be as apparent IMO... I think it is all about the HIGH RPM'S, but what do I know

V2 fmic, razors dual alky
Intake double pumped, -8 feed
PTC 9.5, overdrive by jimmys trans.
Full weight and then some,3900+ with me in it.

So...what turbo should I be using? I think the 6765 is perfect for this combo. What do you think gentleman?

 

[2QUICK2B6]

I made 2 passes on my stock long block car 3,730lb with me ... no head work or cam

uped the boost

car would barley spin the tires for the burnout with the tight converter so i know there is alot left.

I sure like my te45a GTQ. The billet wheel may help but Im staying with the 45a this year unless im forced to upgrade.

You stated eariler that your 67 was rated at 900HP...according to precisions chart the 67HPQ is rated over 900, but the 6765 is rated less.

I don't know how fast your car is, but I think the fact that you went from a Q trim to a smaller exhaust wheel is the reason you aren't as happy as you could have been...If the billet 67 is close to the old 70 then to get close to the same numbers at the track you need the rest of the combo to be the same as well.

That's what makes sense in my head anyway.

What part of Illinois are you in? Id be willing to let you take mine, go to the track and post back the results. I'd only have to change it over to an "E" cover.

Mr. Hartline, I didn't expect it to be a "magic pill". I also didn't expect to have to run more boost to trap same MPH. If I had of saw the post Patrick made about only being able to make 800-850 in a Buick application, I would have kept my 70GTQ. Just as good, if not better is all you heard the vendor saying. I bet you do have cars that go low 10s, high 9s. with it. What were they using before, what's the tune like? I'd like to see them at Osceola too. It wouldn't surprise me if they were TSM quality cars either. :biggrin:

 

[HighPSI]

I apologize if I came across the wrong way. I am not criticizing what YOU are doing. I was talking about purpose built TSM cars bolting a billet turbo on and expecting low 9's.
You mention "ONLY" 800hp. That's enough to break quite a few parts if not set up correctly. I see you car is one of the heaviest TR's I have heard of. I don't know your cars suspension, how much boost your running, or how fast you have gone, so can't say whether you are maximizing your turbo. We sell the 67's to our customers who want to occaisionally "visit" the 9's. If they want to run 9's every time, we sell them a 70 or 71. What are your goals and how fast have you gone?

Don Palumbo won TSM@BG several years ago with an iron headed street car running an old school 67. He went in the 9's but was a couple hundred pounds lighter than you.

Now that is a heck of an offer.

No more street racing after this post.....

Its cool Cal. You talk to my buddy Junior with the blue V8 regal all the time. He and I are like brothers so I know you will help anyone given you have the time. You know how us "Chitown" boys are, its all about the sleepers. Mid to low tens is I want. I know pulling weight is an option but there are a bunch of mid ten second cars at full weight.

Yep she is fat, over 3800# on the TSM weigh in at Norwalk. That was after I removed the 2-15" sub box and the extra full size battery. My best was 11.06@127 1.79 60ft on 24psi. Best with the Billet 67 was 11.14@125 at 28psi. Upper 80s both days.:frown:
Mt drag radials. 275/60 stock wheels. Stock rear shocks dual air bags, 90/10s up front sway bar removed. The car used to 60" in the mid to low 1.5s with the th400 and the transbrake on a crappy high stall converter. It had slippage in the low 20% range in the big end. Now with the PTC and overdrive I'm lucky to get a 1.6x footbraking it and launching at 10 more psi than using the brake and high stall converter(3500). BUT.... it did net me lower trap rpm and 3-4 mph at the same boost and timing.

Im trying to have the good stuff on the car, yet it seems to be little to no gain. This is why I was ticked with Precision, not you. I spoke with a rep (not Patrick) that assured me gains or equal performance at the same boost level before i droped any cash. I see a few people have went from a smaller turbo to this one and saw gains at the same boost level. Great, thats expected! But I have another local car with a 67GTQ. I'd love to swap with him and see what happens.

Sorry for the long post guys. I just feel that I have to be honest with my present results. Maybe it will go faster next time out. I will post if it does.

 

[HighPSI]

Near as I can tell, you are making around 600hp using

TCI® - Sorry...

It's going to take another 100hp to run where you want to run. Although your car is heavy, something else is holding it back.

I got one of the first billet 6765s for my street car when they came out as quoted above. Check out the thread http://www.turbobuick.com/forums/tu...0-pte-6765-billet-wheel-turbo-has-landed.html Mine is a DBB with S-cover and small .63 a/r hot side housing and has the supporting parts. The last time we had the car out at the track, it ran a 10.88 @ 125 - 7psi launch off the footbrake and a lazy 60ft time - 22psi max boost down track. Car weight is 3610# with me in it. These turbos don't wake up until 25# so there is plenty more.

As Cal stated above, this isn't a magic pill - it takes the complete combo to run the magic number. There have been more than a few cast 67s in the 9s and I know this turbo can do it as well but it's ideally a low to mid 10sec turbo that can occasionally dip into the 9s if leaned on. My street car should run mid to low 10s with a little more boost with no problem. We've made a few revisions and plan to get it back out when the weather cools off. Looking at your combo, it's comparable to mine but that extra weigh is costing you at least .2 tenths. I do feel that the 3-bolt Buick housing holds this turbo back a bit. I plan to try a larger housing later on and turn it up to 30#s and see what happens.

 

[KevinB]

I guess I will have to keep an eye on the 2 cars I know of with these turbos. Both have/will have good combos. I need to run 135+ at the track in a 3650LB car. Unless everyone is being tight lipped, I have yet to see one of these turbos come close yet.

 

[Bent6]

Depending on how things play out, I may change my rear end and turbo and come play if this class gets run at BG this year. :biggrin::biggrin:

That would be great! Its a fun class with a great group of people. It hurt me selling my old car so i could switch classes and get a more stockish car but I do not regret it one bit. I will be at bg if ths runs but its not looking good for me getting my good engine in by then. Its ok though, I'm still having a blast with this stock engine and small Turbo.

 

[NCTURBOS]

Kevin,

I wish I could help you out more... I've personally owned/built/installed cars with one/some of the following:

Limit Engineering Te45a (most were Q-trim, some P-trim)
Limit Engineering Ta66 Q-trim
Limit Engineering GT67 Q-trim

If you search on the board here you'll see where I got a local guy one of the very first billet 6768 turbos. Unfortunately before we ever made it to the track he had some bottom-end failures in his motor. But from the minimal initial street tuning I can't suggest that turbo over any of the above. We hope to be back at the track this fall with the new combination.

FWIW,

K.
