BAH!! Screw it!

I'm going for a 10 flat! I've got some people I want to school, and the TGP has the potential to do it. I'm destroking it to a 2.8, running a custom ground Bullet Racing cam, 3400 top end, 150 shot, and my SP70 spool from my Supra. F$%$ it, she's gonna go or she's gonna blow!!!

I don't think destroking is gonna do you much good. The stock bottom end of the 3.1 is good for 7000+rpm. The stroke difference between a 2.8 & 3.1 is like .15", its not that much. I would keep it a 3.1 and do everything you said and it would be a screamer. It would scream as a 2.8 also, but why change it?

I figure in order to hit 10 flat, I'm going to need to spin this baby to at least 8k. Unless I can find a way to make the 3.1 displacement hold up to it, I'm going to have to destroke it.

I think your tranny is going to go before you get near 8k.

After 12 trannies, I think I've got that probelm solved..... I've got a secret weapon....

Just a teaser for all of you guys, the car's build has been going on for quite some time... And times are a lot better than would be thogh, but 90TGP is right. tranny has been my weak point. But I will say this, it's putting enough power to the wheels to really break stuff.

wow that's some high hopes considering there are only 2-3 TGPs i've heard of that even break into the high 13s. i know that has more to do with the TGPs limited production and non-existant aftermarket, but i kinda doubt the 'V' motor even has the potential to break into low 12 territory, but what do i know? :lol: i'd love to see it happen, that's for sure.

The 3.1 block is just as stout as my old Stealth's 3.0 block, and it was a daily driven 10 second car, and weighed nearly as much, if not more, than the TGP will.

I have full access to a machine shop and what I can't do, I have people that can do what I want for me. The reason no one has borken out of the 13's yet is because no one has really pushed the envelope(no offense Jeff). People are still running anemic turbos, stock ECM's with flashed chips, transmissions that grenade over 350hp, and most of the time they have all of the original weight on the car and then some. It's possible, but I don't think anyone has done it, because most of the TGP's are daily drivers and no one really tries. Jeff and a handful of others are about the only exceptions. But they are going off of whats here, with a little work on the side. Sorry, but a chip and a crossover pipe arent going to get you major hp.

Very nice to see someone else (TurboGTU on here few days ago and the Moderator at the 660 Forum-Collins-60DegreePerformance also) of late talking about the benefits of short-stoking for more hp! This has been around for a long time, not as highly known as long-stroking/stroker but still another viable approach to increased hp. Auto engineering books state its hp that takes you down the ? mile and wins races. Think about this, Ferrari and other exotics have been and still do it this way, some revving past 8,000 but still making 400 to 500+ hp out of a small displacement normally aspirated engine, keeping up with, fast as, or beating long stroke American big blocks such as the Dodge Viper. When you consider after each shift point our engines (and many others) drop rpms to 3,500 to 3,800 then rev till shift point, 5,200 to 5,500rpms, so then you make your max power band in those ranges, or like Maxi is stating and I totally agree, increase the rev range potential of the setup by using a shorter stroke and increase your power band to 7,500 to 8,000rpms with a much higher peak than could as easily achieved at 5,500 rpms in our longer stroke engine. Yea slap on a huge ass turbo and get lag out of the hole (brake torque but its still a FWD traction limited car!!), but like Curtis and others, need to make use of its power feeding potential by raising the rpm range! Another who did this way back in the late 80s is Ryan Falconer Racing, his racing engines ran from (stock is 3.31?) 2.9?, 2.7? down to a 2.6? stoke crank, making 350 hp normally aspirated, and with a stock 2.8/3.3L block (per sanctioning rules/requirements). And it don?t take a huge amount of rpms to do this, 7,500 to 8,000 is perfectly well within using a 2.6 to 2.8 stoke crank. There are other gains from short-stroking such as freer revving, better piston running in the bore (anyone that has taken apart one of our engines will note the piston skirt scoring from this 3.31? stroke setup!!) and a host of other benefits well worth this approach! You will also be another candidate (read what I helped TurboGTU with in the Chip Tuning Section) for needing an O-Ringed block etc. So good luck, I would have been long into the 12s years ago had it not been for thousands of emails helping TGP and TSTE owners fixing their cars, seems too that buying a chip and/or pipe gets you a warranty on anything else you might need to fix :lol: but I always like helping other owners! I am nearing completion of the heads and/or turbo setup that others have been waiting for and am starting the ground work for the engine in my TGP. Snagged a new aluminum 60 degree V6 Bow-Tie Racing Block for very cheap, might be able to use one of these Ryan Falconer Billet Short-Stoke Cranks and Carrillo Rods with some lower compression forged pistons to make up the beefy part. Since Garrett has woke up we now have excellent 550 hp turbos with internal wastegates to make fitment of all this a lot easier. Extrude Hone the upper and lower intakes (want to keep stock look/like it!), large TB since it will be needed then, the heads I already do, check the turbo cam in there to see what step up might be good to do, roller lifters (roller rockers and roller timing chain already done) and a few little odds and ends (custom racing clutches coming, soon I hope!!) then finally after 6 years, get to finish up one of MY cars and actually drive it!!!

See Jeff, you need to make more time for yourself!! Lol!

I'm a business owner as well, so I know how hard it gets. But damnit, I'm tired of not being anywhere near my original goal(actual times known, but not announced to protect some research...).

Seriously, we need to hook up sometime either via Instant messenger, phone, or maybe meet up in person, and compare some notes. I think we could learn a lot from each other on this.

Definately NOT new to this. They do net some nice gains, but being an avid tuner of many different setups(and also doing it professionally), I don't consider barely breaking 14's from a 15.0-15.1 stock time a major improvement. I can take a DSM, spend 15 bucks, and drop a LOT more than that.

Sorry. I should have said, "Another TGP enthusiast who is willing to explore the abilities of the TGP, without going the route of the obvious!"

Now before that statement gets misconstrued...I am not saying Jeff's chip and cross-over are not the best option for most! I am saying there are other alternatives to TGP HorsePower or lack there of.

Please MaxImage...don't let me or anyone else get in your way of a 10 sec car...I personally will be joining the race in about 6 months! :wink: 8)

ps...that would be a cool comparison...your Auto to my 5 or 6?-speed

TGpilot, I didnt take it to be mean or anything. I was just replying. No biggie at all.

That would be sweet, but I don't nkow if the auto is going to make the cut. I'm gonig to give it all I have, and pull from the resources I can. If nothing else, my father in law is picking up a few nice pieces of machinery(lateh, NCE drill press, and a few other toys). i can machine a good majority of my own hard parts. We'll se what brommo can do with the rest.
