Can someone with a Whipple and a 3.5" pulley who has removed their hood blanket do a measurement for me. I'm trying to find out how much space is left between the hood and the pulley. Can someone who is running the 3.5" pulley put some putty on the end of the pulley and close the hood and measure. You might have to put a drop of oil on top of the putty so it doesn't stick to the hood.
I'm looking to put a 3.75" or a 4" pulley on. The new Gen2 rotors make 1.5-2 psi more and I want to keep a more conservative boost level.
