Looking for interest in a Lightweight Underdriven Crank pulley
Yes it may take me 20 minutes to install. Although I have had it on, off,on, off etc. I would suspect this should take one hour for the first timer. The hardest step being having a third hand to put in an allen wrench to hold the serpentine tensioner back and probably removing the 4-12mm bolts that hold the pulley to the crank. It is much easier to loosen these 4 bolts when the belt is still in place, although do not remove them until you release tension on the belt. Although with these bolts there is nothing special with them, as in they come off like any other bolt. Then you may want to take a minute to oberve the belt routing just so you can get that right. No special tools, nothing impossible here. Clearence in the are is good so big hands are not a problem.
I will even have a cheesey how-to video for those that need another hand. INcluding a full writeup with text and pictures. So everyone please relax!
PocoRA,
It should be interesting to see what my RA does with the full 2.5" catback and custom intake I made when the stock pulley is in place. Without the piggyback it should be 7-10whp close. Thanks for the compariosn numbers.

I have the numbers although not the energy to fully type all of it up. I will start another thread with everything. All I will say is I will be selling the pullies, the gains are there, Michigan sucks to dyno, and a Mustang Dyno calibrated for 500hp engines is mean to the Ralliart.
Well, what were the increases? Whether the dyno is calibrated to a 200hp car or a 500 hp car it shouldn't matter. It should still give you the difference between a stock pull and a pull w/ the pullies right?
From what I've been reading changing the underdrive pull is like changeing a flywhell, no realy hp gains but frees up strain(rotational mass) on the motor and help rev fast, if there was a problem with it not showing any result that may be why, I'm still gona get one anyway but I wasn't expecting any dyno gains, only 1/4 gains.
