While attending a small car show today (held by the local Impala SS club) I had the privilege of stumbling across this monster, 550HP (510 to the wheels) gorgeous blue twin turbo GTO. Evidently it took 6 months to build and from what I could tell it was worth the wait. (those wheels are Lingenfelter as well) There were a couple of other cars there, mostly Impala's and 1 really nice slammed fullsize truck. Enjoy the pics

 

And here are the rest

 

Looks pretty bad ***, but I guess this would cost a fortune. They already had enlarged displacement engines & SC packages for the GTO. While I think a twin turbo setup would be the best, I also think it would be by far more $$$.

 

good lord thats a lot of hp

 

can you say...torque?

 

I was a little bummed we didn't stay long enough to hear that thing take off but oh well, maybe next time

 

I would have to agree, the owner is some sort of multimillionaire, I didn't want to ask homedude what he did for a living but apparently he's not hurting at all

 

I bet thats nasty in a Straight Line! LOL

 

What's the stock HP on GTOs?

 

^hehehe i bet it's also nasty in teh poket book. but hey if you go tthe money..haha it'd be nic to have...dont' think i'd want to drive it during rush hour around the beltway though...hahaha:D

 

aren't they like 400 or something like that?

 

yeah that's what I thought...

edit I'm a retard and can't do math

 

well i'm sure they were going for reliability or something. wonder what size turbo's they are?

 

I would love to hear that engine. thats just sick

 

ditto

 

you can't get 510 RWHP from a 550HP engine

 

Not if you use Mazda math :p

 

lol you never cease to floor me laughing :p

 

those aren't my claims, those were his, like it matters anyway, it's still a bad *** car. sorry I don't have dyno sheets, a life story of he car owner, the tempature of the dyno run, what soda they drank that day, what they had for breakfast, how many hours of sleep they had beofre the runs, the build date on the car, how much gas was in it or what kind.....

 

eh. drivetrain loss can be caused by a multitude of things. 40 horsepower DT loss would be impressive. That's less than 10%!
I'm not saying it cant be done, but if they're doing it, then wow.

One of the guys at the RX7/8 meet last night here in DFW had dyno sheets of his 3rd gen with him of both the engine and the flywheel. Dynos were done on the same day at the same shop. He was putting down 400 at the flywheel and 348 at the wheels. That's 13% loss approximately.

 

I'm beginning to think he may have been talking about his torque figures and getting it confused with the rwhp, either that or his car is an absolute engineering marvel

 

Keep in mind that some feel drivetrain loss isn't a set %. A lot of tuners think that as you up the HP the loss is less to the drivetrain since you're still turning the same parts and have the same amount of friction. The may have just dynoed the car around 510 and thrown the 550chp number out there as a guess.

 

hey ajax, thats really a great amount, thats really how the flywheel "gains horsepower" people just dont understand that, it minimized DT loss, the same way lightweight pulleys gain HP. you wont gain power but rather maximize available HP to be diverted to the wheels rather than your DT sucking it up. isnt 20% the average DT loss?

and on the same note, if the rx8 "has" 238 horsepower, and they dyno between 170 and 185 most of the time, and lets say average 177whp dyno then the RX8 gets approximately 27% DT loss if factory bhp claims are correct

 

Those sound like pretty good numbers. The new C6s average around 350rwhp and the new 400hp GTOs aren't far behind. It looks like either a 50hp drivetrain loss is somewhat standard with 400hp cars or the LS2 is quite underrated and the RX7 guy had quite a few lightweight drivetrain components swapped in. Either way, that's one nice RX7.

 

"Either way, that's one nice RX7."


^ RX7??????? GTO!
