oh here is the 104+ stuff
"Designed for off-road use in 2 and 4 cycle Sport Gasoline Engines. Increases octane effect up to 7 points. Extra concentrated for high-compression engines. Stops knocks, pings, run-on, and overheating caused by low octane fuels. Cleans fuel injectors and carburetors. Dynamometer tests show Super 104+ significantly increases horsepower in high-compression engines. Safe for fuel cells, liners, gaskets, o-rings, catalytic converters and oxygen sensors. Does not contain lead, alcohol, aniline, toluene or MTBE. Treats up to 22 gallons."

So running a stock Ap1 engine with 11psi pulley on a comptech SC is very dangerous? I am not abusing the engine or track racing but is it really dangerous? Is the limit for stock AP1 compression 10psi pulley?

The universal psi for stock ap1 is no more then 9psi
Where did this # come from? not sure...
But if you're having 0 detonation at all RPM and can run 91 octance through any type of weather be it 100+ degree's F and your A/F ratios look good then 11 might be fine.

[QUOTE]If your not getting any detonation then your fine, its how your car is tuned which is what will dictate how safe it is. Its true that the higher comp you have the window becomes smaller for dialing in timing for detonation tendencies, its all about detonation, so that doesn

Okay, so I rebuilt my motor recently, It has been sleeved, with 87mm 11.5:1 JE pistons
What I am trying to determine is weather to go SC or Turbo, and how much Boost can a sleeved block with 11.5:1 can take, for everyday driving.
Thanks for any input

open it back up and put some 9.x:1 pistons in there
