My 89 RX7 FC bridgeport running 9.4 rotors, T04R, 2 Tial wastegates 38mm, 550cc and 1680cc injectors, Haltech E6X ecu, HKS exhaust, Making 326whp and 254wtq on 11psi @ 7500rpm.

Definitely respectable numbers, but they seem a little bit low for that setup. Still I bet its a blast to drive. Dyno sheet?

 

I will post dyno sheet sometime this weekend.

 

I have to agree. Conservative tune?

 

Agreed. Look at my dyno i have alil smaller turbo and less aggressive porting you should be over 400

 

He's only running 11psi.. aren't you running 18psi?

 

Ah I did not see that.Well i can say one thing that turbo will love 14+ psi its really just starting to come to life at 11 psi.
Crank it up with some w/i and 18 psi youll have nice numbers and with the bridge 7500 seems alil low after all the dyno is the stress test right?

 

on top of that i really do not understand the point of bridging the motor to only tune it to 7500.

the last full bridge i built i tuned it to 9k and it still hadn't peaked out yet(would have had to remap everything to raise the RPM limit and the customer was fine with the numbers at 9k, 449whp).. of course it depends on the turbo but unless that is a T3 framed turbo with a .69 hotside you shouldn't be capped so low.

 

Sorry the motor is an S4 half bridged with 9.4 rotors. And it's a T4 flanged T04R turbo with a 1.00 a/r hot side

 

still bet you had more room to go with the half bridge. was the power level peaking yet?

 

break in tune?

 

is the motor pinned?

 

Yes, I guess you could consider it a conservative/ break in tune. The turbo, transmission, diff, suspension need's a break in. I will be getting an email from the tunner with the graph and map file.

The motor is not pinned. It's an S4 block, HBP on top of large street port, 9.4:1 rotors, RA seals, mazda oem springs, FD oil system, FD stationary gears, e-shaft oil mods, Mazda Racing Pulleys, HKS clutch and flywheel.

 

Finally tap into the potential of that turbo/port setup?

 

dont push it on pump gas
