7sec 3000GT

[GritMaster]

If you want a seven second 3000GT with a 3000GT motor then you drive fairly slowly throught the Quarter take a white out pen and cover up the 1 in 17 :P

or You drop a 429 motor in it and do a nitrous alcohol supercharged with a blower jack up the back and do it Chevy style :P

I'm not entirely sure the 6G72 can support the HP neccesary for a 7 second quarter, I'd imagine you'd need somewhere in the realm of 1800... Just doesnt sound plausible

Keep in mind the Skyline, Supra and Celicas are all inline engines, that might have something to do with it (I'm not an engine expert....)
I Know that A guy by the name of John Lingenfelter (ever heard of him? :P) tuned a Cavalier I4 too 1000HP with only adding a single Turbo... From what I've seen Inline engines respond better to turbocharging than a V alligned engine... maybe not but thats just What I've seen, otherwise if you had the money I'd think a 3000 could easily get up to 1200+ HP, yet the most powerful one is only at something like 865?

Something doesn't work out here....

hmmm lets see whats the displacement.. hmm... 183 CI? say bored out to about 184 x 10 = 1840 running Nitromethane (~10 HP per CI)

Bore out the engine, remove the Exhaust, get a Nitro Supercharger, Use a NitroPropane fuel, Run it through at 50 GPM, Strip out the car, build a CF body for it get a Chromoly tube chassis, and some Slicks, I still dont think It'll work... But Good luck, BTW this will cost nearly 80grand or more...

Oh and be sure to have your car equipped with a parachute and big ass Spoiler that works. I'm not joking here, You're going to need it.


disclaimer: if you kill yourself its not my fault this info is based off whats done to domestic (american) engines for funny cars and drag cars, this is all feasable but none of it is proven on a 3s It's all been proven on 426 Hemi's, so go buy one of them WARNING! you'll be putting out around 5000HP with that engine wahaha Stick to possible stuff, don't say I didnt warn you.

Edit:\ the supercharger spins at 10k RPM and displaces 100,000 CI of air per minute, it should be able to handle your compressed air needs. :P

That's 1/8 mile right? Cause you should be aming for 9's first.

the TT's "could" make over 1000 awhp but the tranfer case will never hold. djforplay is working on fixin that with getting a special super forged case from australia or somthing, he 's got everyting else forged already I believe with 2 x 25G 's he could come close to the 1000+Hp and being the first under 10sec car, the word is he already put 90000 dollars into it. but it aint a done job yet, he is going to go to california to work for GTpro and I am sure they will sponsor him. Bummer he is leaving texas. The market is just to small for big things to happen for our cars. This brings us to front wheel turbo conversions, watch importpoweronline.com chris had a huge single turbo conversion , he brought it to the NGo4 however he had just finished it so it was untuned and therefore no good results. His car was stripped with a chair and that was it so keep an eye on him. It seems these 10sec - times are gonna depend ona few "crazy" individuals as a whole 3S there wont be no masses entering under 10 sec anytime soon unless somone comes with another miracle chemical like NOS

[TurpsGT]

well that cant quite be the case because the "V" set up is exactly what the top feul dragsters use to run 4's

It seems as though the main concern is the gear box being able to support, the horsepower the 6G72 is able to make, and successfully carry the cars mass the distance under the stress, the 3S are already known for the bad gear syncros.

which just goes back to "with a better gear setup and the power this engine can already make...."

I still think 6x 5gallon tanks linked and compressed to 130psi. and two hoses just out side the throttle body, on forged internals, with a compotent feul system, and dualie hooziers on the front should.....

well then theres the whole gear/ syncro thing again

Don't the top fuel car's have a 2 speed tranny? or am I smokin something again....

Turps, don't take offense to some of the responses you may have gotten/may get to this subject. It simply is that many people come on this board every month or so 'determined' to put the vr4 into the 10s, or the 9s. Now I can't judge their true intentions, and do not want to discourage or downplay any of the serious ones, but many come off as teenagers who have watched Fast and the Furious one time too many.

It isn't that there aren't people out there right now trying to do what you are suggesting. There are, the problem is that they are few and far between. The main problem in most peoples eyes is the rariety of our cars.
If you take a look here:
http://www.3kgt.com/dimensions.shtml
you'll see that from 91-99 there were only 86,151 3000gts sold/produced
even if you hypothetically double that to include dodge stealths. Only a fraction of those are twin turbo setups...the 'prefered' car for upgrading(please no NA owners take offense)
That number is less than the honda civics produced last year alone.
Now take into consideration how many of these 3S cars have been totaled, junked, stored away by collectors with no desire to modify these cars, or are simply daily drivers with no sub 10s aspirations.
The numbers just get smaller and smaller.

This translates to a small market for potential businesses. To create an aftermarket part for our car, research and development must be done...this costs a hell of alot. If the company doesn't foresee the profit in doing all that work, they simply wont.
This horrible supply and demand situation leads to a few adverse consequences:
1) a lack of aftermarket support in comparison to the hondas, supras, wrxs, and so on.
2) if companies do produce the part, it ends up costing 3x as much as it should...for me, a broke college student, this translates to a very long wishlist, and only 1 or 2 purchases a year.
3) Not all of us 3/S owners have the technical knowledge to tackle such things as fabricating new parts and modifications. Unfortunantly for some, like me, our knowledge is limited just as much as our cashflow.

While there are many who are taking the initiative, such as yourself, of trying to advance the potential limits of our cars, they unfortunantly, aren't a dime a dozen. Resulting in very slow progress. Few of us have the means, knowledge, money, or connections to truely do more than follow where others have paved the way.

There are those out there who do have the means, the money/sponsership, the amazing companies helping them, the desire, and the technical knowledge to push the limits...and they have, but they still have only managed 10 second runs with turbo setups. Perhaps 9s in the near future, as I believe some of those 10s runs were at ridiculously high altitudes. But 7s at this point (especially in FWD models) seems impossible and you will most likely meet up with more cynicism than brainstorming. I don't mean to talk down on this forum or any of it's members, but as I said before...we hear it alot and see few results.

All I can say is don't dismiss the idea, or get defensive, it is great that people are asking these questions...just realistically realize what you are up against.

well said, bravo

[TurpsGT]

well, your absolutely right I see your point about the rariety of them and the daily drivers that just cant be converted into 7-9 sec dragsters for practicality reasons, although a nice balance is apreciated. I must admit when i pull around anywhere heads turn from the sleek curves alone and its not something you see everyday ( unless you just happen to be select that own it, or neighbor) I love this car because it something not everyone can have. its just a shame that this seems like it will be the only "" supercar never to go sub 10's

im not down about it. im l going to keep trying, I know im not that far off from finding the right set up to do it.

but thanks for your imput

on 3si IPO has gutted an FWD 3S. retrofitted a single Turbo setup. He is down to 2700 lbs and running low12's and still need tuning.

yeah alan just like I said lol, hey I send u a e-mail with a specialfavor!!

[alan92rttt]

If you sent and e-mail I do not recall receiving it.

[TurpsGT]

does anyone know what compression and boost setting he was runing, was there wheel spins or anything else to factor in?

[alan92rttt]

not off hand.
