Single turbo supras seem to be outrunning most other "street" cars (though it's normally from a roll). What's a good setup for the LS1 (block of your choice) to smoke them in any type of race?

Just curious as i'm no turbo expert.. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Sell the ls1 and build a 347 ford with a turbo...Put it in your car with DFI and let it eat, that combo produces 1000hp no problem with a good head.

He said the F word, commie! <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

but if youd rather smoke supras in style, you could switch to the 6.0 iron block and use some good boost on your single T-76 ls1 (or lq6 what ever its called).

A Lingenfelter 427 Twin Turbo setup would get the job done.

Or if you want to remove the LS1, a SBC 427 Twin Turbo setup would get the job done ... and then some. How about 1200HP and 1000Tq?

A 347 ford turbo? Baha, no thanks

That is a great looking set, no matter what manufacturer... <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

That's an awesome setup! How much boost could one run w/a built iron block/T-76 combo? What type of numbers should you be able to push? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

zturbo

t-76 is capable of 950 hp. If you have a properly designed system you could see all of this hp. The one thing to see that much hp come out of the system you will need to tune it correctly (using a fast system or of that sort)

The block can hold it is detonation that will hurt you. If you can tune the car to keep that away a ls1 could see amazing numbers. (not that some dont)

Thanks for the info! What type of intercooler and exhaust would be best matched with the T-76 in a high boost/race fuel application? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

zturbo

header design into a y coming into the turbo. The wastegate mounted as close to the turbo as possible.
Header size approx 1 3/4 - 17/8 depending on heads. if in between 1 3/4- 17/8 step. I dont see with the heads sizes much bigger being needed.
*Single turbo f*** big turbo but can see some design ideas
* Buick v6 but you can see where they merged the two headers together (driver side is not hooked up) and taking the wastegate off right at the y
*another single
If you need some more pictures i have a few laying around that I can scan.

Intercooler can be very diff. You could go to a full drag setup and use a air-water setup. Or you could go to the more street setup and use a air-air. What is the car going to be used for? Do you mind changing water out?

Exhaust you want a system that is free flowing as possible (most turbo guys say to stay away from the chambered muffs as possible)
Bigger the better on exhaust. The less the back pressure you have the quicker the spool. I am running dual 4" off my turbos, using something on the lines of a straighline flyweight muffler. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

i race a friend of mine in his single turbo supra, and we switch off winning...it's always a good race. here are some videos of my turbo SS and a ton of other nice cars.

zturbo I believe I'd prefer to run an air to air intercooler. Do you know a place that makes good ones for f bods? Also, (as I said, I'm new to this) do they make boost controllers for our cars?? Is it possible to have a very streetable (yet still powerful) low boost/street gas setup if I just wanted to cruise, then a high boost setup for high octane? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> Thanks for any info!

Hybrid8x That's a bad *** car! <img border="0" alt="[hail]" title="" src="graemlins/gr_hail.gif" /> I may have missed it, but do you happen to know that cars 1/4 times and estimated top speed?

boosst Could you tell me what turbo setup/octane both you and your Supra friend use on your cars (and what octanes you two use when you race). Which car is the better 1/4 car, and which one wins on the top end? I believe I downloaded that video before, and you jumped at least a car on him, and held him off well, but it seemed he was pulling strong just before letting off. Would he have pulled you had you two stayed in it? What speeds was that race ran from xx-xx? Thanks for the info.

That TT setup has yet to run the 1/4.

But I've seen track estimates of high/mid 8s.

Its in an 82 corvette which weighs about 3300lbs in stock form. At this point, the car is probably coming in under 3000lbs.

With a 1/4 mile calculator, and using 3000lbs for the weight and 1200 for the HP, you get an estimated et of 8.40 (give or take an entire second <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> ).

it will never go 8s cuz he'll more than likely break the IRS before that happens, but i've seen a beefed up IRS 84 vette with 28x10.5 ET Drags go 8.60s before with a 410" small block and a 100mm with small boost

i have the T-60 single setup. i run 101 octane with 9lbs of boost when i race him. his turbo is quite a bit bigger and has a bunch of lag..that is why i jump him. up until lately i could hold him off but he is changing a few things up and i can't seem to hold him off any more. i just got the powerplate cutout and the 2 step and i will see if that doesn't help out.
his best is 12.2@120 i think, and mine is 11.9@118...the air at our track that night was over 6k <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />
they are both mid to low 11's on a good day.
we usually got from a 40 punch because we both usually have stree ttires on and we will stay in it until about 130 or so.
i need to get a video of us running from a stop with street tires <img border="0" alt="[boring]" title="" src="graemlins/gr_zzz.gif" />

I'm building up a 408ci engine. 8.5:1 compression pistons, 6.0 L block, stock heads, forged rods, crank, etc, only reusing the heads.
I have a t60 to put on right now, I know it's small but I built the engine for peace of mind. Later I'll try to get a t88 to fit in there.

I will be makeing some interstate challenges on the supra forum later on just to test my setup out as it goes.

A boost controller will work with almost any wastegate setup. I run a Innovative turbo one personally. As I also run their wastegates.

Alien nice setup that turbo is gonna hold you back something fierce.... Cant wait to hear what ya do with a real turbo on there <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

Steven

If you run a aftermarket computer i dont see there being much of a problem.

Fenris Ulf

The LS1 Motorsports kit looks promising, with the proper rotating assembly I think an LS1 can definately give those Singles out there a run for their money.

Ian

Here's another newbie question for you guys. I've seen the Supra guys running various T-88's, T-72's and T-76's on 3.0 liter engines. Are these size turbos then some of the "smaller" turbos to be used on V8 cars?? Would bigger be better?? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
