Has Anyone with a 1,000rwhp+ Supra Raced a 1,000rwhp+ TT Viper Yet?

[fencekey]

On a highway roll.

I just got done reading the September 2007 Road & Track 200 MPH Shootout and was impressed with the Hennessey Viper's performance. It hit 200 mph in less than a mile.

I know Tommy Bahn's anthracite hardtop did slightly over 200 mph in the Texas Mile event and he didn't even get on it hard until 1/2 mile point. That was a 3.0L + GT47-80 car I believe.

I know that TT Viper's can range as high as 1,400 rwph, but lets focus on the one in the magazine that had 1,100 rwhp for conversation sake.

Would an 1,100 rwhp Supra be able to take the Viper from a roll on the highway? I know Peter Blach raced the old orange Hennessey Viper that dyno'd 930 rwhp and Peter dyno'd like 904 rwhp. Peter beat it from 60 to 170mph by 1.5 cars or so.

As a plan my future build on my Supra I would like to be able to take down a Viper like the one in the magazine on the highway. I guess I should shoot for 1,200 rwhp or so. Probably a 3.4L with a GT47-80 would do it (or perhaps a small 50 shot). Don't like the expense of the 3.4L though; would rather do it on a 3.0L. Thoughts?

3.4L and GT47-88mm,

You better work real hard to get it to hook up on street tires... the viper guys are getting it figured out and laying down 1100rw on street tires that will dead hook in 3rd gear from around 100mph.

BFG Drag Radials are street tire enough for me. Oh, and haven't met a Viper on the street yet that I didn't beat. I figure I'll lose to one eventually though. 800rwhp+ Vipers are few and far between on the street, whereas 800rwhp Supras are everywhere.

Depends no the area... just watch out, they sneak up on ya.

[chidoks]

why would you need a 101mm turbo? talk about overkill.. 3.4L gt47-88

or a 3.4 with a 101mm but hey
....i hope you like lag

[Boostys]

you don't need a 101mm turbo...Was that a joke?

[Pantera]

The closest I have ever seen was a fully built supra(Single turbo iam guessing) vs a Hennssey 800TT in person. both where very indentical in performance.

Just know this....an equally prepared Viper rated at the same HP will ALWAYS beat an MKIV supra in any race. Viper has better weight distribution 49/51 f/r and weights a little less overall (curb vs. curb) despite having a much beefier trans, rear-end, rolling stock (wider wheels/tires). And more importantly, the 8.0L V10 will have a MUCH better area under the curve, lightening fast turbo/boost responce, and more overall HP potential than ANY inline 6 on earth....stroker or not. Yes, you can build a certain supra to be able to beat 'Vipers' but never one which is equally prepared. ...The Viper is simply a faster platform with more potential...pure and simple.


...this is why almost all of the fastest, most famous supra owners sold their cars to step UP to a Viper years ago.....I've owned 6 MKIV supra's over the years (including a BL67 built auto one today), I would know...and I love supra's! But nevertheless, everything else being constant....

1000rwhp Viper > 1000rwhp supra

1600++rwhp (no NOS) Viper.....has no equal!! lol.

[Ravan17]

^^hard thing to do but i agree with you.....kinda hard to compete with something that more then doubles your displacemnt even stroked.......

thats why you have to love the fact that alot of viper owners are previous supra owners they dont talk shit to us, unlike mustangs, civics, firebirds, ect
its what i like to call competition you can like

Agreed.

I think you're wrong about 1K whp vs. 1K whp in a roll race because the Supra has better aerodynamics. For example, I recall Peter Blach (one who has owned high HP versions of both cars) saying that a Supra needs several more whp to run high speed rolls with a Vette, and the Viper needs several more than the Supra.

Also, a lot of high hp Supra owners have also stepped back "down" to the Supra after owning the Viper, which, granted, probably has a lot more to do with POS Chrysler quality and ergonomic design than with outright performance potential.

along the lines of what i was thinking, but u summed it up perfectly...

[KylesTT]

Sooo about that race Peter had in his supra at 900whp vs a 900whp viper? How come Peter won?

[ROGUE GTS]

Check out the supdawgs II Video... Or better yet ask Andrew what happened last time he ran an 800rwhp viper.

[fencekey]

Good points.
Numerous guys that have sold Supras to go to a Viper have indeed returned to the Supra. I guess reliability/build quality has to be factored into the overall platform characteristics.
From a roll, I think that the Viper's instant boost response is completely negated. A high revving Supra off of a brake boost has great power under the curve. On a road course, big single Supras stink whereas the Viper would shine. I'm more interested in roll-on highway races though, which is where most big hp cars want to race since traction is so limited at lower speeds.
Viper is a great platform due to the displacement, but very expensive to get to high hp numbers.
There is a guy here at work who bought a brand new 2007 Viper Coupe and he wanted more power so he pulled the motor and had it built, stroked, heads,cam, etc. Had to replace differential with different unit and change some other stuff to be able to better road race. He'll have 600 NA rwhp and matching torque. Cost of the car new plus the mods is mind boggling. I'm not trying to turn this into a cost thread, just noting it. I'll have a big smile on my face when my 95,000 mile stock engine with just mild cams and a bigger turbo and fuel takes him down. He'd get me on a road course though.
Would still like to hear from Peter on what he thinks about highway rolls between Supra and Viper since he has had both.

[OneJoeZee]

I raced my 800hp Supra against a friend's 800hp Viper in Gran Turismo 4.

I won, therefore the Supra would always win. Always.

Yes, I unplugged his controller once during the race but who cares? I still won.

800hp Supra > 800hp Viper.

/thread.

N/A is one thing... but a 97-99 GTS can make over 800rwhp for $15k... oh and do it on pump gas... for 100k miles.

Over 1k rw is expensive no matter what car you own.

Uh, I doubt a 1000 HP Supra is the most reliable car ever. Besides, you act like the Supra's interior is as good as a Porsche or Ferrari or something, which is a joke. Granted, the Viper's sucks, but at least it has a factory oil pressure guage.

Probably not compared to lower powered setups, but at 750-ish I can attest that they can be very reliable. I've never broken anything on mine in the past 6 years of being single and always keeping the boost up.

Every bit as comfortable as those and better ergonomics, IMO. Not as high quality materials.

Granted, the Viper's sucks, but at least it has a factory oil pressure guage, thanks to the donation from the Neon parts bin, which seems to have supplied most of the interior bits.

Fixed.

Speculating a bit here, are we?

[fencekey]

Agree

[roadtalontsi]

The viper is the clear winner...
but on another note... Traction, the fact that 1000rwhp supras like to run 305's rather then 355's could have just a little to do with it. If more supras would slap some widebody rear fenders on maybe they could hook better, or just put a straight spool in the rear end lol.

and finding anything 1000hp on the street what a joke. Especially a daily driver. unless people have drums of c16 in there garage. which is quite possible if you can afford to make 1000hp but if you can do that, then you drive ferrari's and better cars on the street cause you can even if they aren't as fast.

Not at all... there are quite a few vipers with over 100k miles and many have had big nitrous shots and blowers along the way. The motors are dead nuts simple and there is no reason to think they won't last a very very long time.

Or you just drive an 8L car that will make over 1k rwhp on 93 pump gas.
