I believe the snout from Arrington Magnuson kit is 90MM but I haven't measured it. Wondering if anyone noticed a difference in IAT or higher RPM performance by upgrading to a larger throttle body.

Install a Magnuson 90mm snout along with a Arrington throttle body on my 6.1 at 6psi and the dyno result was a minimal gain in HP. Clearly not worth the price I paid for parts and dyno time................
