I would spend the money on a standalone, first off. Whether youre at 7,9, or 14PSI. Standalones are the way to go.

Like they say, make sure everything is installed properly, and tuned by someone who knows what theyre doing. Tuning will make or break your motor.

The stock clutch can withstand a pretty decent amount...mine has held up to ~28k+ of 6-11PSI, and its still engaging. Could it grab harder? Sure! But it still serves its purpose
