Coming from a Stang background (03 Cobra w/13+lbs) and many friends w/either whipples, turbos, roush s/c's I say you will enjoy either one that you put on. If it's your daily driver and all you want is a nice "kick in the pants" feel you can't go wrong w/this mod.

Lots of intelligent posts here. Reliability wise,,get it professionally tuned.

 

Alright, I'll probably give it a try and put the kit on myself. I currently have underdrive pulleys on right now which I figure I will have to get rid of. Does anyone know how to put the original Crank pulley back on with a torque wrench as far as numbers (pressure) go?

 

Yes, you will have to for the Roush because of the supercharger pulley. With the Saleen you'll be underdriving the supercharger, so you don't want that either.

I think you need a new crankshaft pulley bolt, since it appears to be torque-to-yeild. I had to replace my crank pulley because there are no holes drilled in the pulley and had to install an earlier model pulley. I had to get a special puller for mine since it had no bolt holes, but a standard harmonic balancer puller should get the old pulley off. You can probably rent a crank pulley installation tool from a parts house. Here is the procedure for tightening the bolt.

Using a new crankshaft pulley bolt, install the bolt and washer and tighten the bolt in 4 stages.
• Stage 1: Tighten to 90 Nm (66 lb-ft).
• Stage 2: Loosen 360 degrees.
• Stage 3: Tighten to 50 Nm (37 lb-ft).
• Stage 4: Tighten an additional 90 degrees.

They also recommend a dab of silicone over the crank key slot before installing the pulley to prevent future oil leaks.
