Re: LET Motorsports Pulley Special!!
So the 178 and 181 will work with the stock ECU, etc.
We know the 178 is proven reliable. What about the 181?
Also, anybody know the HP difference between them?
Edit/Update - I found a post stating that the 178mm adds ~20hp and the 185 adds ~32hp. I estimate that the 181 would add ~25hp over stock. Sound correct?
