Default UNDERDRIVE PULLEY ?

Well I'm running 11.60"s on the stock motor right now and was wondering what your guys opinion was on if I should put one on or not at this point.
Currently have a ST-3700 ,MAC Headers,WHISPER CATBACK&MAF ENDS oh yeah lots of weight reductions ending up with race weight of 3200

The pulley is easily worth a tenth and 1 mph at the track. This has been proven too many times to count. Excellent mod.

moving this thread to the Engine Tech section

Yeah i have underdrive pulleys and they are pretty nice, the crank pulley and the alternator pulley were changed out and they probably knocked off .15 off my ET.

you can get the ASP pulley/pullies from about any of the sponsors of this website....i did buy mine directly from ASP which was dumb cause it was a little more expensive but ohhwell <img src="gr_stretch.gif" border="0"> i thought for the 189.99 or whatever i got belts and **** but i was wrong <img src="gr_stretch.gif" border="0"> ohhwell, i'd recommend getting them from one of the sponsors....Thunder/Tbyrne/MTI(just calls em MTI pulleys instead of ASP)
