hello,

I have a 2008 GT500 and my goal is to beat 200mph, i was wondering if someone already did it, and how he did it.

Is the Steeda supercharger pulley with the Cold air intake and dyno tune would be enought ?

Thanks you for helping me.

 

Where are you going 200 mph?

 

thats a crazy goal. id rather go 130+ in 10 seconds...i have taken my stang to 174 mph and wont do it again nerve racking especially with other cars on the road.

 

Were i am there is 200 mph contest on track. and want to make my GT500 able to do it... it is on a long large and strait closed road so there is no risk at all.

 

arent you racing the clock to 200 and back to zero? i may have heard something about this.

 

It is exactly this, just a run at big speed and back to 0.

at first i'm not looking after the clock, just to reach 200mph, and when it will be done, i will look after the clock and try to score.

 

even with the extra 100+ hp and tq from the pulley tune and cia it would take much more to do it

 

That car is a tank and I don't see you hitting 200mph easily or cheaply. Hell the new ZR1 only hits like 205 or something and it has like 620hp and it's more aerodynamic. Good luck, but don't see it happening.

 

well the kenne bell gt500 supercharger will get ya 800 hp and 700+ tq thats a good start

 

I would bet money that this set up would get it done. True the S197 body is like a flat wall in the wind when it comes to arodynamics. 800 HP is alot of power. IMO that would get ya there!

 

It might get him there, but the question will be, ho long is it going to take to get him there. I'm sure this road is only so long.

 

after that theres alot more that can be done

 

i met a guy at the ford nationals with a shelby supersnake and he had 725hp and his car was only up to 185 on a track he said, you will need like 900+ hp i think.

hears pics of the supersnake.

 

the ZR1 might be the sexiest car ever made.

 

If you read the current issue of 5.0 magazine, or look back in an old issue of MM&FF (I don't know which month), there is a car featured in there that competes in the Silver State competition. I don't remember if that is the name of it, I left my magazine at work, but it's north of Las Vegas in May and again in September. In this competition there are different classes for cars to complete 90 miles in the fastest time, 125mph, 150mph, and unlimited which is atleast 200mph. The guy's car is a race preped 05+ with a ~400ci Dart block with a Vortec F1-R supercharger (may not be correct spelling/letters for the SC) It develops close to 900hp.

You will need around 900 HP, and some Aero mods atleast. And then I'd hope you build it safely with a cage, harnesses, seats, ect. to accompany such speed.

I like the goal and wish I had the means to do it myself.

 

That is a pretty badass goal.

Other than nearly doubleing your horsepower i would expect that is the first of a lot of stuff you will need to do to accomplish this.

My question is, is this your car? a sponsored car? The 200mph goal is fuggin badass, but absolutly rediculous as well.

You need to take a good time to think about how much yer willing to do to yer car. Building it to hit 200mph is possible, but when yer done how streetable will this car be and will it be fun to just take out for a cruise to burger king and back?

there is no way yer gonna hit 200mph in that gt500 and still maintain the integrity of the overall driving experience that the car is gonna give you.

I mean hell, yer gonna need a buttload of suspension workthat would be specifically geared to allow you to move 200+miles per hour in a straight line or maybe on a large oval/circle track

Most cars that go over 200mph were designed with that kind of top speed in mind from the origional concept, and were built in a fasion to keep the drivability compromises to a minimum. Your GT500, as badass as it is, is built off the same shape and design as the V6. It is just way more built and has a bigger engine. The overall design of the car is already not setup for that kind of speed, so boosting power is simply overcoming a design flaw with brute force, rather than building it for the ground up with that speed in mind.

Once you gut that ******, double the HP, get the aerdynamics figured out, suspension planned, steering planned, etc, yer gonna have a car built to go 200mph, not a car built to cruise around in.


if anything thinks im wrong on this let me know. I just cant imagine reaching that mark without severly compromising other aspects of the overall driving experience.


Tell ya what, go get a Mustang 5.0 gut it, figure the suspension, and put a fully built supercharged and juiced 460 in it and calll it a day. Keep the GT500 for a fun car.


Remember, if you dont get it right the first time, there is a chance your GT500 will be torn to millions of pieces.


But hey, if you have the money, the time, and dont mind the possibility of changing the drivability so profoundly that it wont be fun to cruise around in anymore, and dont mind the possibility of shredding it to a million pieces of smoldering scrap metal across the track, and you just have the money and **** it, you just wanna haul *** 200mph down a track in a roided up clydesdale mustang of the apocolypse while flipping off the four horseman as you laugh meniaclly down the track at incredibly stupid speeds.....

well... then i guess you just qualified to be my hero! **** YAH!

 

I think you can get to 200mph if you install 4:30 gears

 

900+ hp isn't impossible on this engine certainly would take some work and even more money

 

900hp isn't impossible, it's actually pretty easy. Nothing some twin turbos couldnt handle, but I agree with Jack. You gotta do a lot of other work besides the engine work. If your goal is to jsut get this thing to 200mph just for some competition and thats it, I'd say it isn't worth it unless there was a prize that is very significant. More power to you though if you have the money and time to do. On another note, I saw a pretty badass looking GT500 the other day. Lowered perfectly, nice exhaust, black, and some very well done rims (looked like Fikse rims)

 

SAGE ADVICE! The streetability aspect is serious especially as you start crossing over the 600rwhp mark. The car becomes a lot more difficult to drive when power levels get silly.

You need to have the bottom end built stronger to handle the added power. Start with something like a Manley/Eagle/Scat/Carillo billet connecting rod set, ARP fasteners, and a full blue-print assembly. You'll need to have the heads well ported and set up for sustained high RPM & high boost, nice big blower cams, a blower upgrade or a turbo conversion, a HUGE new fuel system from tank to injectors, 2.73 or 3.08 gears, FORGED rims, fixed back racing seat, hans device, 5pt harness, cold-fire extinguisher system, 8pt roll cage (welded in), life insurance, another car. You should also get a bigger steering wheel so your steering inputs will be slowed down at speed. You don't want that fast a steering ratio at 200mph... puts you in the wall if you hiccup.

You may want to look into the ICS Titan head gaskets too. Running under boost in 5th and 6th gear against the kind of aerodynamic forces you're going to see is very hard on a motor. Plan to do some repairs after the run.

 

Haha holy hell. After all that, what would he be running in the 1/4? lol

 

with traction 9s at most

 

set up with the suspension how it'd need to be with the gears it'd need to see 200mph the car wouldn't 60ft for ****. 900hp only buys you fast, not quick. Supercars are super light weight so they can have both mind altering speed and fast off the line performance. They usually also make use of what I think of as excessive rpm capability for a street car to do so.
