Hi all. I want to know how much boost you guys think my car should make, and then I will tell you what I am actually getting.
I recently had a leaky snout seal on my SC, so I swapped the blower with one that I rebuilt and ported on my own for fun. (I didn't take the rotor pack apart, of course.)
FYI, the stock blower was making about 11 psi.
So, I ported the inlet as far as I could without cutting and welding. I included small flares on the inside of the case like an S-port. I also ported the outlet a little - really just filleting the lip on the underside of the exit, and cutting the bolt bosses back a little.
Next, I coated the rotors (yep, myself) with a spray-type epoxy coating. (Consider this a durability test for the club. Results to follow in a few thousand miles.)
Finally, I swapped the pulley to a 10% overdrive steel pulley. I thought I was going to need a new belt for this, but the stock one seems to fit ok with the tensioner still within its range.
And my exhaust is still stock (don't worry, not for long ...), so I am not losing boost because of a non-restrictive exhaust.
So, what would you expect it to make? Thanks!
