Re: Stage II - 15 psi

Watch yer self...  It's nice to have the correct timing/temp curves

GRAYDON 89 OCT.  SHAME ON YOU!!!

Actually its 225 @11.5psi  My car with 15PSI gets "About" 250hp  When it 
"OverBoost's" to 67.5" hg (18.75lbs Boost!) I've got "About" 285-300hp 
depending on outside temp.

Bump the cam timing 1 Tooth (16 Deg "Crank" Advance) and reset the 
distrubitor. It will move max boost down to 3000 or so and take a little 
at the top... but hell your forcefeeding the engine anyway so who cares 
when the cam opens the valves!

Yes...  Experience speaking here!
