I learned alot today and although I didn't quite reach the 300rwhp mark I am still happy with the outcome and my ping is GONE! The car also feels alot smoother and the fan temps were lowered.
stock, untuned 278hp 317tq
after tuning 283hp 316tq
minus Flowmasters 291hp 323tq
Bottom line the car did not perform better by adding more timing in the upper rpms. The power/torque curve pretty much peaks at 5000 and 4100 rpm respectively. My valvetrain was floating at 5800rpm but I think I need to readjust the valves and use 3/4 turn as opposed to 1/2 past zero lash. The tuner seems to think my Cobra intake (ported lower) is holding the power down. I'm pretty much falling off @ 5600rpms. Even with a different intake I guess the point would be mute without upgrading the valvetrain.
If anyone wants to comment I would appreciate it. I would post the graphs but they are a winPEP 7 file.
Thanks!
I found it very interesting that with the Flowmaster 2 chambers disconnected the car picked up 8 rwhp. Although I did not reach my goal of 300hp I came pretty darn close and the ULTIMATE goal is to attain high 12's at the track and with this data I know the numbers are there, now I will need alot of practice.
