GTM Stage 1.5 Pulley Recommendations
I'm about to switch my car over to e85 and dyno tune the car for 550hp but I know I'll need to pull more boost to do so. I'm currently running a 94mm pulley that came with the 1.5 kit but I was thinking about going to an 85mm pulley to achieve 12 psi of boost. I used an impeller rpm calculator and found that with the stock crank pulley and the 85mm SC pulley, the impeller rpm would only be 37,359 which isn't near the limit for the Rotex C38-61. But I have read around here and seen that other users say you can't run that small of a pulley on the SC because it will max it out. Any suggestions or advice is welcome!
