ended up getting a second eaton M62 s/c to play with... many guys get good results with porting of the eaton s/c's. gains of 10-15% with reduced IAT... you see some guys with cobras getting +40hp etc... well 10% of 400hp is 40hp.. even the guys on the mini cooper S's with the M45 get good gains ~20hp
while not expecting monster gains the goal is to reduce IAT's as the charger will be spinning faster and to reduce parasitic pumping losses
still work in progress but i can show you how much the outlet port has been opend up. thats pretty much the maximum it can go. its to match up exactly with the 120 degree timing of the rotors. the rotors edge is exactly parallel to the outlet port triangle.
the edges at the bottom which will be ground off and the bolts which go on the other side will be shortened. (not shown as yet)
pic of stock outline in green for comparison... ill post more pics as more work is done. inlet side is done very shocking casting processes from factory much can be improved here!
silencer holes can be plugged as these are a "boost leak" effectively and bleed boost back into the rotors to reduce sound. block these and the s/c will be crazy loud! not much performance gained from doing so and gain about 0.5psi boost.
once this is done its going to be time for a smaller s/c pulley. plan is to grind down the stock s/c pulley total 7mm to 87mm (stock is 94mm). this is the lowest you can go before you have to delete the s/c clutch and this will bring boost up to ~14psi (1bar) measured at the FPR. :thumbsup:
of course more pix to come and results as things move along..... i want to sqeeze out every last HP i can!!
