550RWHP & 650RWTQ @21 psi with "75" shot nitous. Just say YES to NOS!

411RWHP & 472RWTQ @21 psi all turbo.

A little disapointing on the all turbo run since I put down 435 & 401 @ 18psi on similar setup on a DynoJet Dyno. These runs today were on a new Mustang MD-1100 Dyno here in town. I guess this was in the ballpark with what the guy at the shop said. He said the Mustang dyno usually shows 30-40 HP less than the DynoJet. The hp-tq #s were flipped from what I had seen on the DynoJets. I was expecting higher hp than tq on the all turbo runs. I wasnt sure what to expect with the nitrous runs other than a MONSTER! Over six hundred Ft#s!!! @#$%^&*^%$!! Im also excited that my clutch held that much torque.

If you're talking to me, there's no hate intended in my response. I'm talking about the actual gain in power off the "75" shot is a lot more than 75 HP ;).


No harm done! The nitrous jet is the size referenced to "75Hp" on the NX chart for a supra. (non -turbo? I can't remeber). As well as the direct effect of the nitrous, the cooling effect is going to play a big part. Later on, in the exteme heat of the summer the nitrous helps out a lot! The nitrous gets the turbo spooled up VERY quickly too.

Nice Numbers!!!

I'm sad now. Since Jay went 1J I thought I was one of the biggest 7ms around. I guess we have nothing better to do in Alabama then to build cars.

Generally you get more hp on a boosted car with nitrous. I got 62 RWHP with a 50 shot with 4 degrees taken out. :biglaugh:

Nice numbers, looks like all alabama made it into this thread,well minus 1 so far ;)

Also is your turbo a "bolt-on"?

Yeah, my turbo is an "old school" Suprasport Stage III. Its on of the t3/t4 hydrids. They dont even list the thing now. I think the "BOSS" thats on their website is basically the same turbo though with some improvements.

Thats bitchin man! great numbers, 21 psi seems high for that but it still turned out awesome especially for being on 550's.

good stuff
