94 SC on a 92 Pulley swap
 
For a while I've had a 2.25" pulley on the 94 SC that I put on my 92. Call it a test run. Well, I put the stock 92 pulley back on it. It made a great difference in top end. Low end torque suffered a little bit, but is much more happy above 3000 rpm.

With the 2.25 pulley on a 94 or 95 SC, you get into the heat loss zone where the SC is running very inefficient at the higher RPM's.

Unless you find a way to intercool or water inject, always stick with the Stock 92/93 pulley size on a 94 or 95 SC, never smaller.

Yeah, I know, but I thought I'd give it a try. I can still peg the boost gauge, so I know I'm still getting more boost. ;)
