Stock bottom end, 7 psi, 600+ rwhp These are results from an 00 Vette (M6) with a stock bottom end, AFR 205s (unmilled), TraK cam, Fast 90/LS2 TB, and LG pro LTs, being fed by an old school P1-SC at 7.4 psi.
Car made awesome power, on 93 octane.
Biggest surprise was how much it picked up since the last tune session.
Car originally had a Ram twin disc, which apparently had no desire to hold all that torque (even though it is 'rated' to over 900 ft/lbs).
A Textralia ExoSkell was swapped in its place, and the car felt like it picked up 100rwhp.
Last time on the dyno, the car was running 42# injectors and we were running out of injector up top, so the main goal of this tuning session was to dial in the 60# units, but we never expected to see such major gains from the clutch swap....
The belt was also slipping a bit here, it would plateau at around 7.3-7.4 psi at the end of the run, but its making pretty sick power, so it will be fine for now.
First graph is the new final numbers.
Second is the new numbers vs. the old numbers with the Ram clutch and the 42#ers.
Check it out: (thats a gain of 75 ft/lbs in the middle....)

I guess it just depends on how you like the power to come in.

SO you think the extra power came from the clutch swap? I am running the Ram twin disk with the aluminum flywheel.
BTW great numbers from a stock shortblock.

Thats coming on pretty damn strong in my book....
Yes, 99% of the power gains (especially below 5Krpm) HAD to be from the clutch swap.

good numbers...I was recently tempted to buy a P1 to go with my 408. I would have done it but my wife is going to have surgery so I can't do it right now.
If I do...damn...I hope for numbers like this. I would only run 5 psi though. Keep up the good work. Give up some track numbers...

So on a stock bottom how long are you thinking it will last roughly with a safe tune and such as you have?
