1000 rwhp
What is the best way to get to 1000rwhp "safely" without the car blowin up in my face( by the way I have a 1994 mkiv supra tt) I have seen some turbo kits/engine kits for the supra but what would be a better and safer method a parallel twin turbo or a single turbo and which would be quicker spooling and I am planning on a alchohol/meth injection because this will be a daily driver too. I already have wider fenders to accomodate bigger and wider tires for traction and what other modifications should I make like body, transmission wise because a guy blew his transmission when he was running his supra.

Either way, the #1 way to do it "safely" is with race fuel. No way you can get that on meth alone, unless you fill your entire fuel tank with it. After you've got it firmly fixed in your mind that you absolutely will need to run race fuel in your fuel tank (no pump gas at all), you'll also need a complete fuel system upgrade, a very large turbo upgrade, a standalone ecu w/ignition amplifier, and lots of dyno tuning. Also, the oem 2jz-gte will handle 850rwhp (6spd), but for 1000rwhp you'll need to replace the connecting rods (preferrably with Carillos). Quote:

The other mods depend on your application (drifting? autocross? highway pulls? 1/4 mile? standing mile? roadracing? 1/8th mile? daily driving? etc.) Hopefully that info is enough for us to start a dialog... |
Its a six speed and I'm not running any tires yet because I havent decided and I have seen other 1000 rwhp supras run on pump gas 93 octane and they didnt seem to have a problem and I have seen people achieve a lot of horsepower without race fuel.... This has nothing to do with the topic but is it true that the more displacement an engine have the faster the turbos will spool and that they will be more powerful, jw

Personally I don't see the big deal. "Race fuel" is just different 'brew' of dinosaur remains. A 3L engine means you can still make 25+mpg on the highway (off boost, of course), which is something you could never do with a 10L big block v8. Sure the fill-up will be a bit more pricey when you choose to put down that 1000rwhp...but a 3L engine is lighter too, which helps overall hp-to-weight ratio! Quote:

thanx for the info and answering all my questions and what octane race fuel should i use? By the way your extremely smart and basically knows everthing about supras and engines agan thanx for the help.

The octane of fuel depends mainly on how much boost you need to run. To make 1000rwhp with a 6spd, you'll likely have to run about 32psi of boost (depending on turbo size, timing curve, tuning, cams, etc.), which means you'll probably need pure c16 (116 octane) fuel in the tank. |
Ok so 116 octane fuel, what turbo size and what kind of turbos would you recommend and what would be any company that does the type of fuel system upgrade that I need to run and what other adjustments like strengthening the block or anything else I would need, btw how much does 116 octane fuel cost?

One more thing what should I do to the tranmission I know you said to rebuild it but where should I go and what parts should I get to upgrade the transmission. I really dont like rollcages but I think it would be smart to put one in what would be a good rollcage that wont obstruct like when I get out of the car or anything else because I really dont want it to look like a full blown race car. what would be a good suspension upgrade

basically what I want this car for is as a weekend track car that handles pretty well, nothing extreme, and a car that I can take to drag racing events. How much boost will the car have to run at to achieve 1000rwhp and if I lower it can I run on pump gas I know that it wont be 1000hp but when I just wanna drive it.
I saw your supra on the links your work is amazing how much horsepower is it pushing out or how much is ur planend horsepower |

Note: If you want to build a 1000rwhp Mkiv Supra that you can both dragrace and roadrace effectively, you're talking some REALLY big $ - probably close to 6 figures. If you want it to be show-quality too, then you'll be over 6 figures easy... Quote:

Low 9s to high 8s and i forgot you said 32 psi. Well thanx for all the help and Ill keep you posted on my progress. And one more question from an earlier post from someone else you said that the oem stock internals have to be changed after 900rwhp what has to be changed? What is a safe boost pressure to run 93 octane gas(pump gas)

With the stock ecu, 16psi is max for safety & engine longevity. The more you push it past point, the faster your engine's performance will measurably degrade. Oh, don't forget that with boost spikes and boost creep, it's a major undertaking to rock-solid reliably keep boost down below a certain level. In other words, don't expect you'll be able to simply pop in a $400 boost controller and run 32psi with a big turbo one day, click a switch, and then lock that same big turbo down below 16psi...it's nowhere near that easy (in fact there's probably only a small handful of amateurs that have ever achieved rock-solid-reliable boost control in all conditions). This is a pretty complex subject - please let me know when you're at the point that you've got the cash ready to start building this particular part of your system and I'll give you some pointers. |
Forget the handling part its just gonna be a weekend Drag racer and when I said "nothing extreme" I meant like suspension wise just so it will be able to turn right and wont kill my back when' i go over potholes. Would it be a good idea to take weight out of the car cuz I know that less weight equals more speed but sometimes it means less traction One of my freinds told me not to take weight from the back instead from the back though the supra is a relatively heavy car not bimmer heavy but heavier than a 350z or an evo or sti. By the way I have about 60k scrapped up right now that I can spend for modification (I already got the car) I think this will easily get to 80k+ but it all depends on what I do

Carbon Fiber is better than fiberglass right(I think its stronger and lighter) though expensive but will suit my purposes um are there fully carbon fiber fenders I know about doors and trunk lids, hoods but I dont know about fender are there cf fenders and bumpers. Is a wing necessary cuz I love the way the wing looks on the supra or will it slow me down.

Umm one more question what did u mean when you said topspeed do you mean like the salt flats or topping out the speedometer

How fast you planning to go 250mph i presume especially with 1250hp faster than a bugatti veyron or twin turbo hennessey viper

I know you have to worry about aerodynamics(lift and drag and a bunch of different factors) and cooling cause the engine gets too hot at high speeds and it is extremely hard to get to that speed, why do companies like maclaron, bugatti,ferrari, and many other companies spend millions on expermenting. The only way to get speed is to have rwhp.
