If it fails, the IAT would increase, and it will just pull timing, but the AFR is still safe. Using it that way, the temps are around 40-50 degrees cooler if I remember correctly. Another option is an ICE tank, but that isn't very convenient for the street. The Air to Air craze that Procharger touted for years when competing against Vortech was marketing. Yes it's convenient, no it's the most efficient way to keep temps down. Especially today with the power cars make.

A friends built H/C P1x car is making 822whp @ 14psi and it doesn't knock on E50 with IAT pushing 165. I have 22-23 degrees of timing in it. But then again if the OP has the same size race intercooler, the bigger supercharger is going to produce hotter IAT's pushing another 170whp. With the PD stuff, the IC bricks are also upgraded. I believe the 3.0 has larger bricks than the 2.9.

Moral of the story, Liquid cooling is better at keeping temps down during a hard pull, Air to Air has better recovery time post pull.
