My Dyno #'s
95mph... It pulled pretty nasty... I "had" a SPEC 3 in it until the 4th pass...
I hear MM is having goodluck with the SPEC 4 and is working on a SPEC 5 now... so I'm gonna see about picking one of those up. Honestly, I didn't expect this 3F to last very long. Overall, I've had a really good weekend, glad to be back home.
Here's a rundown on the motor
Eagle Forged H-Beam Rods
Wiseco -25cc 2618 Forged Pistons
P Stage 3 Heads (2.08/1.60)
Cam(231/224 .595/.578 116lsa + 4)
Yella Terra Rockers
LSX 78MM
Undoubtably theres a weaklink somewhere thats choking me up... Notice the torque was a lot more than the HP, I'm pretty sure that had to do with the turbo being small. I turned the boost up a couple pounds towards the end and it wouldn't push anymore. So that leads me to believe it's undersized and choking out. If anybody else has any suggestions I'd love to hear them! It made decent numbers but I've been around here a while and I was slightly dissapointed it didn't make more. I can't complain though... it still runs.

I guess by upping the boost all that you were doing was adding heat to the intake as the 70 couldn't provide those CI's anymore gusto.
But with that type of power i'd be happy as a pig in ****, it'd keep it that way for awhile

It's fun to drive, thats for damn sure. That turbo sounds so nasty too... It gets a lot of attention.
I think that turbo being sized for a rear mount STS kit originally is holding you back. You can see by looking at the dyno graphs that it is coming on soon, coming on hard.. and then it is done! The first graph is the last pull, showing the air fuel on that run. The second run (in red) was on it's way to being the best pull, but Andy saw the fuel pressure move a little bit and we let out of it on that pull. Overall, it made some killer power with the 103* temps in the dyno room and with the 93 octane in the tank.
