Depends on your cars weight, his cars weight, and driver mostly. Actually, it also depends on tires (depending on who can get better traction on launch). Anyways, I don't think this question is specific enough....I'm tempted to close it but I'll leave it open.

I love all your sounds.
My supra is a 7m all is going into my car in this build is this:BorHor;881405 said:
forged pistons and rods
ported and polished head (intake and exhaust)
walbro fuel pump
550cc injectors
stage 2 clutch
aeromotive fuel pressure regulator
Map ecu
Plx wideband
3 inches exhaust
turbo header
67 trim turbo (the one in my picture)
hks 1.5mm metal head gasket
arp head bolts
2.5 intercooler hard pipes
Apexi blow off valve
Electric fans
and i have removed the stock seats and put in 100 lbs lighter, removed the back seats forever and other stuff.
Do you think that would be enough? how much horse power do you think it would give me?

You should be near 500 on the 67 on 93 pump. You need more fuel on that turbo though. I think you are cutting it very close with 550's. You need 680's on a 67mm. Ditch the efans and go back to a clutch fan.
that rx-7 proubly runs low 12's if not high 11's or better in the 1/4 so if you run better than that you should be fine.

didn`t mean to offend, my english is not so good, i ment if you have a history racing a rx7, how it was?
We know what you mean.. But it shouldn't matter. There are so many variables, so every single race is different. Just do it then report the out come to us.

It's going to come down to the tune and how good the drivers are. That rex *COULD* run mid to low eleven's at it's current power level. 400hp rx-7s are monsters.
Edit: Oh, and even if you take 500lbs off your car, his will still be lighter, lol.

ive raced several and there quick but the torque of the supra as the higher gears get used just make it pull away big time.Quarter mile is normally where the rotarys are quicker.....As a reference we have a local guy that has poured big money into a rx7 running a 13b bridgeport(mazfix built) with high flowed turbo big injectors standalone ecu brandname everything on the dyno put down 320rwhp., and he raced dan from rolling start who has a turbo A that at the time had a blown head gasket on no.6 and he was getting 325rwhp.When they raced dan stayed right up his ass all the way to rather illegal speeds and when they pulled over dan laughed at him and said"hahaah mines stock" after that they werent very good friends anymore...lol and my cressida eats the turbo A for breakfast so i keep trying to get a race out of the rx7 but he wont do it.Any doubts this story isnt for real i can provide any photo and maybe even a vid if the rotary guy is keen for another run.

That makes 2 of us. Dude ur driving yourself and the rest of us crazy. From what u have said , the parts that you have for ur build will give u more than enough power to beat a 320hp rx7. Just finish your build and hand his ass to him:evil2: Nobody is taken this the wrong way it is just that some many things make a difference in this. Especially u the driver. Please put the lock on this:biglaugh:
