Majestic motorsports had a supra dyno day out at there shop located in Jacksonville, NC. Sean from Titan motorsports showed up with his 1000+ whp MKIII supra, then Majestics had anouther 1000+ whp supra on the dyno. Desided if I wanted to know what the 240 is putting down then this is the place. Did only 2 pulls and made 267whp and 233tq

Not to shabby. Ill be editing the video hopefully today.

From his SIG FMIC, Exhaust, Greddy knockoff IM, Air Filter, clutch, flywheel, J30 diff, and running @ 12psi.

Wonder how much torque you loose when switching to lighter flywheel. And is that fact or fiction. That when putting on a lighter flywheel engine revs quicker but looses torque?

Lighter flywheel should show an increase to the wheels since its less mass to spin resulting in less drivetrain loss.

^^^ thats what I have always thought. Every car that I modify I replace the clutch and flywheel.

Yeah my sig pretty much tells it all. I think If I ran maybe 14psi I would have been around 275whp. either that or dp, and downpipe elbow.

Check out the vid....

I didnt expect the hp to carry all the way up to redline. I wonder if I bumped up the rev limit to 7 or 72 if I would still make power.

Very nice. I dont know about you but i want a bigger turbo already. 233tq just isnt enough.

Nice...

The only difference in our mods is that you have a freddy intake manifold and regular fmic. I have stock manifold and same-side fmic.

I wonder if I should be around that too. Hopefully! There's a dyno coming up soon, to which I'll be attending.

I talked to sean from Titan motorsports and he said the only thing he would change about my setup would be the cold side intercooler piping. He didn't like the 2.5 reduced to a 3.5 So I think my next upgrade will be 3.00 intercooler piping.

Thanks for all the good comments
