Default underdrive pully

im thinking about buying an underdrive pully and i was wondering what kind of gains of loses i would be looking at if any. I tried using the search but didnt really find the answer i was looking for. Right now my only mod is an slp lid and my 1/8th mile time is 8.57 at 87 mph.

No SOTP gain but with other mods it all adds up.

yeah don't expect miracles.

but it is worth something.

subjectively everyone seems to say the engine revs faster...a testiment to there being less drag on the motor.

if you ever plan to do a cam...swap it then...since the pulley has to come off anyway

The ASP crank pulley is part of the whole combination of incremental improvements that makes the total package work efficiently. See my sig. All small stuff but it works.

Engine will rev a little quicker and it will help out alot more when you perform H/C swaps or anything more indepth. I think I gained about .1 in the 1/4 when I put mine on full bolt on car
