John Henessey

Has anyone read the Motor Trend article on the tuner's latest batch of hopped-up vipers? Jesus! Those things are INSANE Everything,from the fatter tires, to the beautiful body kit to the 800Horsepower screams out ultimate sports car. Geez! twin turbos on a viper! It's the end of the world, fellas.

Just a week ago there was a Henessey Viper for sale on EBay for like i think 250,000. It had the full package turbos, and it did 0-60 in less than 4 seconds, unreal i agree. It was going to be featured on a mag, i cant remember which one though. But yeah those Vipers are bad ass.
Toodles...
:devil:

Yeah and the stats are in. 833 HP and 902 lb-ft torque. 0-60 in 2.43 with slicks. And this is not even the strongest street Viper out there. An almost unknown company, Super Viper Systems, or SVS, made a Viper called the Styker two years ago that was twin turbo. 993 HP and 1014 lb-ft torque:eek: The lastest one from them that I've heard of has 993 Hp and 1141 lb-ft torque!!!!:eek2: I can't even imagine what it would be like to drive that car.

The Stryker is pretty well known.

Vipers are hot!

250 grand is a lot for a viper. Yeah, Hennessey makes AWESOME stuff,a nd the stryker is good (how come I've never seen it tested???)

Nor have I. What mag? Issue number?

Hey im just wondering if any bodys got any 800TT pics cause i love the Viper. Wahts cool bout the Viper it that it represents good old Amercan Gas Guzzling V8's and V10's.:D :D

Ill get the issue number tonight.

heres some pics:

Thanx man those r some really nice pics. But I kinda wanted pics of the new 2001 Henessey Viper Venom 800TT. I dont have a scanner so i cant scan the pictures out of the May or June 2001 Motor Trends.:D
The pic of the 800TT burnin rubber is bad gass!!:sun: :eek:

Heres some Pics of Vipers!!

The site I was at said those were the actual pics of an 800 tt. Anyone know the official website?

Well, it's official now! The new speed demon.

Hennessey Viper Venom 800 (http://www.motortrend.com/june01/ttviper/ttviper_f.html)

heres the burnout:
http://www.motortrend.com/june01/ttviper/viper.jpg

The Vemon does the quater in 9.99 seconds. Also, I thin Vipers can be hopped up even more. If F1 guys can get 1000+ horese out of a 2.8 leter V8 then we can get much more than that out of an 8 liter V10. Of corse it won't be street legal.

...and it might not be too reliable or long lived, either.

Yeah your right. The F1 guys change their engine after every run.
And those 1600+ horse Skylines engines probably only live through the dyno test.

i think they should put some non-slick tires and put the side mirrors down and then do some more runs. kinda getting cheap there. that viper is freaking awesome though. 725 hp at the rear wheels!!!! thats freakin crazy!!! i wish i could work over at hennessey. :):)

Same here, but why non-slicks.

well slicks give you better traction causing you to go faster. no one tests 0-60 times and 0-100 times, etc... with slicks(that i know of). that car is still going to be faster than any other car i know, i just want to see "normal" times.

:eek:Thats freakin crazy!!!:eek:

Todays F1 cars use NA, 3L, V10's with 825 hp.
In the 80's, they had 1.5L Turbod V8's with 1300(!)hp! Thats about the same power-per-litre as a top-fueler. Only a top fueler would blow up after a mile at full throttle.
Gives you some respect for those F1 teams, huh.

It makes me envy their budget, yeah.

hmm... they ran slicks b/c it would literally burn the street tires off the rims. a 0-60 run would be a joke b/c of all the wheelspin with street tires... that is why the 0-60 runs in such high powered cars arent that great, b/c they are traction deprived unless they are running slicks...
and they are still killer cars

I think the 0-60 on the 800TT was somewhere in the high three's...

Motor Trend...i think may 2001 has the 800 TT and they say 0-60 is (i think) 2.4 seconds. that does not sound too bad. 0-100 is around 6 seconds. 1/4 mile is around 10 seconds

oh..forgot to say that was on street tires:)

DLM makes some great cars for drag racing applications. I know Doug and he does great work when it comes to superchargers. Don't try taking his cars out on a road course.

For the rest of you Hennessey fans, don't be blinded by all of the hype that is thrown out there about Hennessey, because he is on the verge of bankruptcy and has a habit of ripping people off.

If you did a search on the Viper Club BBS, you would also find that Hennessey has had numerous occasions to rip off Viper customers of his. Let the buyer beware.

Ya, i know all about Hennessey, that theif. i hate that loser. i hope he gets locked up.

Uhh:rolleyes: :mad: :rocket: :flamer: :eshooter: :badass: :aug2: :greenchai :monkeypis

He's done some crooked things, I hope he gets what he deserves!

If you measure performance with 1/4 mile and dyno numbers you are probably correct. Doug specializes in drag racing applications. He doesn't do any road racing or top speed applications (yet).

Do you have a DLM blower with spray on your Snake?

Have a good Thanksgiving.

Got it from a post on CarandModel.com, but it was originally from autoweek....

Hennessey's Vipers are fast, but lawsuits say he serves them up too slowly. (Photo by Mark Vaughn)
Ninety-eight percent of his customers love him, John Hennessey says. But a few hate him and some have sued. Hennessey Motorsports in Houston specializes in tuning Vipers, adding more power to what is already one of the most powerful cars in the world. Hennessey’s Vipers have been featured in this and many other magazines and the cars he has sent to us and to other media were impressive performers. Hennessey presents himself well, projecting an image of the consummate Texas good ol’ boy whose reassuring conversational style and howyewdoin’ demeanor put customers at ease. People believe they will get what he says he’ll give them. But not all people do.

According to a lawsuit filed in Salt Lake City, Utah resident Taig Stewart sent his Viper GTS to Hennessey last May for an engine upgrade to 1100 hp along with several other modifications. For that he wire-transferred $142,500 to Hennessey. The lawsuit states the parties agreed the car would be done by mid-July 2001. As of press time the car was still sitting under a tarp in Hennessey’s shop in Houston. Or most of the car, anyway. Stewart’s suit claims Hennessey sold the car’s engine, transmission, wheels, tires and hood. The suit seeks return of the money, the Viper and “no less than $1 million” in punitive damages.

Hennessey claims he’s just slow in getting the work done.

“My side of the story is we’re planning on finishing his car and planning on giving him everything that he paid for,” said Hennessey. As for the parts being sold, “That’s totally false. We’ve got all his parts in the shop except the hood and he wanted to do a lightweight hood.”

Stewart is not the first unsatisfied customer. The longer we dug the more dissatisfaction we found. Here’s a sampling:

On Nov. 14 a New Jersey court entered a final judgement of $133,674 against Hennessey on behalf of Viper owner Gary Dan for a botched conversion.

William Walters said he is out over $22,000 after shipping his Corvette to Hennessey for a head and cam package that was never done; he did have five rods bent and a head gasket damaged on the dyno in Hennessey’s shop during an experiment Hennessey tried with nitrous oxide.

Jerry Johnson said he had to file suit in Placer County Court in California to straighten out registration and engine computer problems on a Viper he bought from Hennessey. n Jon Belinkie said he loves the changes made to his Viper but had to sue in his home state of Maryland, then register the judgement in Texas, to recover overcharges Hennessey made on his American Express card.

Rick Ryan said he had to hound Hennessey for eight months by long distance from Marietta, Georgia, to put the proper wing and stripes on his Viper.

Mark Lublin said he sent his Viper cylinder heads to Hennessey for new valves but when the heads came back he found the “new” valves were actually used; a cam that was delivered to Lublin in a Hennessey box turned out to be a stock Chrysler cam. Lublin was finally refunded $5,715 from American Express but only after nine months of disputing the charge; and he got no money from Hennessey.

Bruce Iannatuono said he ordered $8,500 worth of Hennessey parts for his mechanic in Baltimore to install but was only able to use two-thirds of what was shipped, and then only after haranguing Hennessey for six months on an order that was originally promised in five weeks.

Most of the complaints come from outside Texas. Hennessey, some said, tends to take better care of local customers.

“If you were out of state, man you were fair game,” said Kyle Kent, a former employee at Hennessey Motorsports. When an out-of-state car came in it was sometimes parted out, with the wheels, tires and whatever else looked good going to other cars waiting to be finished or sold outright, according to Kent and others inside Hennessey Motorsports. Then Hennessey would call the car’s owner and try to sell him an upgraded kit. If the customer balked, Hennessey would take parts from other cars in the shop, or just let the job sit.

Kent described one typical disassembly on an out-of-state Viper. “The motor and transmission went into a Durango John was putting together, the brakes went to someone else, the hood went to a guy in Ohio, the rear bumper to South Carolina, man you name it. We had multiple cars like that.”

Another common practice was putting stock parts on what was supposed to be an upgraded car.

“One customer spent $130,000 to $140,000 and that guy thought he had purchased a Venom 650R package which he thought came with the stroker motor,” Kent said. “John told him he was getting a stroker. He was just getting heads and cams.”

Hennessey denies any wrongdoing.

“I’ve got probably 3000 customers,” he said. “I’ve built over 300 cars and out of that I’ve had a handful of people that I’ve had some sort of a delivery problem with and I’ve had some of them who have sued me. So is that some sort of a trend or is that par for the course?”

What are you talking about? Where are you getting your info that Viper engines can't take turbocharging or that they don't last long? Please be specific when making comments like this. Don't let Hennessey's POS make you believe that he is the best.

833HP TWIN TURBO!!!!!!! 0-60MPH - 2.4 Seconds!!!!!!!! I AM SPEECHLESS!!!!!:

i know this a very old post, but who cares. Hennessey built a 1000rwhp Viper earlier this year. John brought it out to one of the local spots on the NE side of Houston a couple of times, that thing is a beast. He builds awsome cars but........I've meet the guy and all I can say is he is a Jackass. His TT800 Viper lost (with him driving) to built single turbo Supra on spray. They went from a 70mph roll out on the Beltway.

Every once in a while he posts on some of the local Houston boards, like Westsidemustangs.com, Houston-f-body.com, and sucidekings.com befor it shut down, it was funny as hell to watch John and one of his old tech's go at it on sucidekings.com. He wont even show his face on the VCA board. :p

About the thing with the Supra, is john that bad of a driver is was the Supra just that powerful?

Originally posted by Whitebread

the Supra was running 25psi on a single turbo and 200shot on top of that, so it was a little of both.

Ok, that's a lota boost.

is nothing to laugh at----but its also a twin turbo on a big block. You can slap a Vortech blower on an aluminum block (small block Cobra engine) add an intercooler to the V8---spin it at 20psi to its max----and make more horsepower than the Hennessy add ons. I'm not trying to bash----but if the Cobra had a big block------you'd be seeing over 1,000hp on a daily driver with a Vortech.

Vortech;

Yeah and watch your engine nuke itself after a few runs too. What are you talking about? You don't just slap a blower onto a Viper and watch it produce HP. What you are talking about is building a dyno queen that won't do crap on a track or even be driveable. The kind of boost that you are talking about is just stupid.

Doug Levin is building great engines that can't break 10 seconds because they are twisting the chassis up like pretzels. They get no traction for more than half of their 1/4 mile runs.

The other thing that you fail to mention, is that in order to get an engine to last more than a few runs, is that you need to swap out the creampuff pistons and drop the compression. You are showing how little that you know about Viper engines.

I would venture to say that you and most Viper owners would quickly kill themselves if they did what you are talking about. At best case, they would torch their engines and maybe put the car into a wall... and live to talk about it.

Stop reading that garbage in magazines...:rolleyes:

who the F&%$! are you talking to like that, you fu&*en white trash muthaf&*%a-----Yes, I'm coming down to your level. Obviously you don't know what forged internals can do with a 01 aluminum block + 20pounds of boost. For starters it will easily produce over 800hp. You don't know shit buddy. Because for a V8----thats pretty damn impressive-----regardless if its supplied through a centrifugal blower. You don't know shit------because my post clearly stated that for a big block it isn't overly impressive---considering the power output of an aluminum V8. You obviously don't no shit about the Kenny Brown Cobras and Sean Hyland Motorsport Cobras that have been built and that can actually whip ass in real life track time. Thats the problem with you Viper guys----you know ONLY ABOUT YOUR CAR!!!! You don't shit about mustangs and the potential from the engine buy to the rear end. The only thing keeping me from running 20psi on my blower------is don't have any forged internals except for my crankshaft. Fu&K you, dumbass. You wanna blast my head off--when you don't know shit about what you are comparing too. If you can't provide a rebuttal to something you don't agree with---then shut your F*&Ken mouth. But don't shoot your mouth off about something as stupid as you claimed in your post. I didn't rip anything about the twin turbo----merely pointed out that with a smaller engine------could make more power. I may not have mentioned the forged internals on the previous post----but I'm doing it now. You have a lot of nerve talking to people like that-------you probably own some piece of shit Honda with that gay growling sound.:finger: :devil:

I would love you see you run 20psi on a your cobra motor with just forged internals. BOOM!!!! those SHM engines are not stock engins with lots of boost making 800hp, it's a very built motor with alot of boost. Also the 800TT on a dyno will make about 900RWHP, that's alot more than 800 at the flywheel on half the boost of the SHM motors. Did I mention large amount more torque it make over the SHM motors?? Have you not heard of the 1000TT? it made over 1,100rwhp on the dyno on a few more pounds boost.

Oh, and the "if the cobra had a bigblock" statement is very ricer of you. It like one of them saying if I had a turbo, Nawwwwsssss setup I would kick you domectic ass. Hell if you have a built big block with that much boost and you not making 1000hp you have problems.

And its true you can make a smaller engine with more HP, the Supra beat the 800TT Viper with only a turbo 3.4L I6.

what the hell do you think I mean when I say forged internals---just the pistons? Hey retard------when its said forged 'internals'---I'm talking everything forged except the block. Do yourself a favor-----go to Englishtown some time----and check out some of the mustangs down there that have the set up I'm talkin about. And I'm not talking about about 5.0 engines----4.6 Cobras are a plenty. Thats why I don't even like posting on these boards----because of doofus' like you that pick and choose a few words here in there and try to mislead people on what the claim of discussion was. Happy Thanksgiving

Hey, when are the 2003 Camaros coming out? Oh thats right, I mean 2005, 06, 07, or whatever heack year they will be able to take the losses on the production of that 'nobody wants this car' camaro.

I meant to say forged internals + 20psi + and an air/air intercooler. Wanted to add that----before your silly ass waisted time posting on how wrong I am. Learn a thing or two about new mustang technology. Theres a whole new world outhere son.

vortech, you're hilarious man.... over-reactin like that.... its hilarious....

OH and about your "quality Slowstang technology" if their so great why did Ford recall the Cobra's for "quality issues"

best of luck on getting all the anger problem taken care of.... :wave:

check the news only the first week of every month. Cobras have continued to roll out of the hanger. Quality issues have been resolved. Dodge never recalls? Chrysler never recalls? Honda never recalls? Yea you are so right----about the recall. :eek:

yes, they do have recalls, but you are talking about how much boost that the enigne will handle, when they are having engine problems on factory boost settings........ just a little ironic there to me.... I beleive that one of the problems was engine blocks cracking......

oh well, I'm NOT going to dip to your level of flaming, just merely trying to figure out what you're talkin about, or if you're just such a Ford Fanatic that yuo're blinded to their problems.

20 psi is a lot for any engine, let alone a driveable one. No more flaming, or else the thread is closed. Debate away, thats why this forum is here.

correct 20psi is a lot for an engine, however, with forged internal components & a heavy duty air/air intercooler----and a good tuner---well, you have an ideal match. Its been done, so its definetely not a pipe dream.

Vortech does the new Cobra have independent suspension in the rear like the viper and corvette?

Yes, it does.

If you put all that power into the car and want to drag race it, don't you risk the possibility of breaking the halfshafts as Viper 10 said it would do in a Viper? Especially if you wanted to put slicks on, which is what you would want if you're going to go all out with drag racing.

is the 01. The 01 half shafts have been reported to break on hard launches with some cobras that have no forced induction-----but gear swaps. I actually swapped mine for the 03 half-shafts----because they have durability up to about 600hp---anything above that---then they are a good candidate to snap like a twig.

I think every one knows the solid axle is still the only reasonable choice.

It would probably be easier to eliminate the independent rear in the Cobra as well, its the same size as a GT so if a person didn't want to spend the money on building up a strong rear end they could go with that one.

Viper 10 if a person wanted to eliminate the independent rear suspension in a Viper, just set it up so it would be able to use slicks, then what do you think could be used?

Devil:

This is what separates the posers from the racers... an independent 4-link rear assembly with quick change gears.

I should note that this rearend assembly was not solely designed for drag racing (as the title of this thread states). It is really designed for racing applications, and will withstand some serious HP and torque. It can be easily used for drag racing, without going to a solid rear axle.

A solid rear axle with traction bars is totally impractical for street use.

You have to lower the compression as well. You will probably be rebulding every few runs if you don't. Just thought I would point that out.

Do you want to do business with Hennessey? (http://www.viperclub.com/viewtopic.php?t=2189)
