What make those Supra's so fast?

As for the gauge and dashes... To this day I hate the C4's dash/guages/interior. It's no wonder that GM completely got away from the C4's designs with the C5.

Yea Supras are fast. I am by far more impressed by the all Mighty GN. Quickest car I have ever driven. Deep into the 10's with a stock motor. Mostly bolt ons to do this.
I want to own one some day.

Don't be fooled by dyno numbers. 90+% of these monster Supras are sitting on stock rear ends and normal all-season tires, and they can't deliver once they get off the rollers. Not only that, the most monster models can't start bringing in the power until 3-4,000RPM, and by the time the turbos spin up, the race is over. It could probably beat a C6 Z06 in a 2 mile race, but in the quarter, they'll get dusted by almost anything. Most of the big power supra owners I've met always have some excuse for not getting to the track-it's because they'd be totally embarrassed by a Porsche Cayman or a stock C5.

Came close to getting my door blown off by one a few weeks back. Guy said it had just a little over 650 rwhp in his..

Are you more impressed with the leaky front and rear main seals, the crappy handling, or the lack of any braking ability? I owned a GN and an '89 TTA. They were more trouble than they were worth. The only way I would ever own another GN is if the suspension and brakes got the full pro-touring treatment, if the interior got a complete upgrade, and if the 3.8L was replaced with something else that didn't have such an awful exhaust note. I would swap in a 2JZ just to make Buick purists angry.

Not all Corvette owners are true auto enthusiasts.

The first time i drove a turbo car, i too thought that it only had top end, and this comes from flooring it, and going from a vacuum situation in the manifold (negative boost) to a boost situation, depending on the cars torque converter, this is a period called turbo lag, and should NOT BE CONSIDERED related to any particular RPM range.
A turbo car can make PLENTY OF POWER DOWN LOW, these ideas of a turbo needing to be at 3-4k before making power are old wives tales.
As a general rule, forced induction cars are going to be faster than normally aspirated, unless there is a big difference in tune or cubic inches, now this is not an absolute, but in most cases is true, they just make more power per cubic inch, because they do the same thing as larger cubic inch motors, they put more air through.
Now, to give a little props to the great old GN platform, i respect them greatly, they made me very proud when i was very young about how freaking fast an AMERICAN CAR COULD BE.
Take a look at what was available in the mid eighties, there was nothing, the GN's engine, and ignition were way ahead of their time.
I had two GN's, one was stolen almost immediately, the other served me well for about 13 years, was incredibly reliable, the only problems it had were associated with racing, and trying to bring it to 500hp.
If i did not mess with the factory tune (it was pretty fast stock) there is no doubt in my mind i could have gotten 200k trouble free miles from it, like many in the community have done.
And as for the suspension, i personally loved it, much like a luxury car, with a GREAT ride, power everything. I was not into auto crossing or anything like that, so the suspension was fine for me, i can see someone that was would have a problem with it.
Brakes...hell, you are right on those, and it was a challenge i usually lost trying to keep all of my GN's fluids inside the car, i was told all forced induction have this issue, i do not know if that is true.

Actually the Supra was made entirely between 1986 to 2002 for two generations. Before that it was simply a hopped up Celica with "Supra" on the back.
4 years after the Supra was introduced? No. Four years after the MK4 was introduced? Yes.
1993 to 1997 is 5 years. 1998 to 2002 is also 5 years dude. So incorrect.
I agree with this.
Also why do people ignore that Toyota's Most powerful Supra was comparable to the ENTRY level C5 with an automatic? Here's some numbers.
1993 - 2002 Toyota Supra
HP 320
TQ 315
Weight 3350 - 3400lbs
1997 - 2004 Corvette
HP 350(LS1) - 405(LS6)
TQ 360(LS1) - 400(LS6)
Weight 3275 - less 3200lbs

i wonder how many miles you could get out of a 400hp supra. my money says the c5 making the same power lasts way longer. i want something that lasts that can take a serious beating. there are so many people out there still road racing 100k+ mi vettes beating the crap out of them for years.

Why is it I have never seen a Supra at a track event? I think "The Little Old Lady From Pasadina" would spank a Supra.

We didn't eat our Wheaties?
Most of the ones I looked at the vettes are getting creamed at the light, I'd first have to look at overall gear ratio at launch. Most of the videos you can't see the ET's/trap speed well or at all.
The supra'a are definitely making horsepower and getting it to the ground. Turbo inline should make good power but suprisingly we still have a weight advantage, don't know what the Supras top speed is.

Not true. Fully built Supras can have 10,000 rpm redlines. The fastest ones at the standing mile are hitting around 250 mph at ~9,000 rpm in 5th gear, so one less shift compared to a lower redline. The top speed of those kinds of beasts would still be much higher in 6th and would be terrifying. They can hit 180 mph in 4th gear in the 1/4 mile drags, so again, one less shift helps. And this kind of advantage can be extremely useful with the built auto trans cars too.
Vipers suffer from poor aero, which is the #1 reason they aren't near the top ranks of standing mile competitions, coupled with the lack of ability to rev like other big engined cars such as the Ford GT.

Because there aren't many around. Turbo MKIVs are rare cars. When you have a dime-a-dozen sportscar like a Corvette, the chances of seeing quite a few at a track are good. I never see any baby pigeons around, but they obviously exist.

All that i know is that the guys in my group that knew the most about turbo charging, had good things to say about the supra.
When you are talking turbo charged engine, it is important to point out, HORSEPOWER IS ADJUSTABLE. You can always turn up the boost, and make more.
It really is not as easy as that, you have to have the correct octane, the correct A/F ratio etc.
The limit on the horsepower, if you have the correct supporting mods, is where and when the block will cease to exist in one piece.
This is where the supra is tops, as i said before, it is over-engineered, whether corvette purists want to admit this or not.
The GN could safely handle HP up into the 450-500 hp range, where you could make a mistake in tuning, and the block would still be in one piece.
Once you get into the 600-650 hp range, it will take it (really, i have seen it), but one mistake, and you are sweeping up what is left of your bottom end with a broom, and dustpan.
The supra, with a stock block, and bottom end can go well beyond this, if i remember correctly, that gentleman that had one could probably give us a good amount, but i believe it is 800-900 hp (that is outstanding for a stock block imo).
