How can Supras push 950+ HP?!?!

If you read the ebay auction and the thread Lagtime posted it made 958HP to the rear wheels which is actually 1127 HP at the flywheel and it did this with a 74mm GTQ turbo at 27lbs of boost..... It's also important to keep in mind this is a 6-speed car so on the dyno it will make more HP than an auto car (6-speeds have less drivetrain loss)!

I didn't read it that closely, that's good information. Even more impressive from a 183 cubic inch engine. Seems almost impossibly with a 74 mm turbo at only 27 psi, not that I would actually know. I would have thought the wheel would need to be larger. Is it running NOS, that would make more sense. I'm too lazy to look up the car and follow the link and read up on the details. Seems like you probably already have.

Yeah it does have nitrous according to that thread over on supraforums.com, but I'm not sure how much and I'm also too lazy to look it up...... I really wonder what a Supra like this would run at the track? I'm guessing mid to high 10's @150mph unless he did some serious suspension mods and got it to hook.... Also, racing and especially launching a 6-speed car with that much power is far from easy!!!

Agreed!

Does anyone run Supras at Bonneville? Seems like the salt flats would be the best place to race these cars.

remember that hp is torque over time, so rpm plays a huge factor in hp numbers, they never give the torque numbers or the rpm the hp was developed, i would bet it was in a much higher rpm range compared to the v-6's run, and if there is no torque down low then the launches will suck, and poor times will be the result, take a dyno numbers from of a street turbobuick, and keep the torque at max hp, and then add another 1,000-2,000 rpm to it and watch that hp number get real high real quick, there is more to racing than max numbers, it takes the whole cake to make a dessert, not just the cherry

I definitely agree with you

I remember this being posted awhile back and someone said imagine the HP #s for the TRs if they revved to 8K rather then mid 5000s

also a huge factor is their heads and cam
4v aluminum head (their heads flow 230cfm intake and 150cfm exhaust stock)
and 2 cams
thats twice what we have, not to mention 16 year old technology that still keeps up and beats newer stuff
dont forget its an inline engine, so there is less likely knock since it goes only straight up and down, whereas a V engine goes up on an angle
they also have a pentaroof combustion chamber to prevent detonation (I think)
they also have dual knock sensors
dont get your hopes down because of the supra, remember their dynos our on race gas(probably 116 oct)
you want to compare something
try either of these situations

1) if the TRs with their technology from back in the 80s were built now with as much of a technology leap that they had over all the other cars back then

2) compare the 1986-87 turbo supra to the 86-7 TRs ( I rest my case)

Amen to that!

Look at a rotary motor. No torque, they have to launch at about 8000 RPM to go anywhere.

Here's one of those "HighPower Supras" ..
