Turbonetics HP Curve.... (when does it get funky)
Turbonetics HP Curve.... (when does it get funky)
The cams make peak power @ 6250 approx. As the boost is increased the maximum horespoer peaks earlier and then flattens out or starts to decrease before 6250rpm due to compressor efficiency issues. At what boost level does the curve start to suck?

Sorry.... yeah to the above. I am thinking of going to a Greddy TT. My built motor is about to go in and I won't be happy with anything but a normal hp/tprque curve and less than 450 whp. I won't be happy with the peak HP at like 5250 rpm. I'm really hoping the Alphawerks headers and my exhaust will keep that from happening, but I'm not sure it will.

The car AAM tuned for Modified Mag was 14psi IIRC and the curve IMO sucked. Torque fellon its face @ 5000rpm's and hp flatlined around that. JET-you obviously know my opinion of this (but dont share it) 
Mind sharing your spec on the built motor? I'm having my long block buid and head works. Also wondering if it worth it to throw another 2k for sleeves.

I have.... .020 ovebore, Arias extreme duty 9:1 pistons, Eagle H-beam rods, stock crank, stock heads milled for true flat, and HKS head gaskets, and L-19 head studs. That should be good up to 550rwhp with no problems.

I havent seen the high boost TN cars ever make power beyond 5500rpm...sometimes earlier. We've tried a few of them here. Still fun cars to drive, but they arent making power through the powerband.
