RSM Ported Engine
As most of you know, an engine is basically an "air pump". The more air you can get in and out, the more power you can generate. Of course, you must also keep things like Air/Fuel Ratio, etc. in check. To promote heavy breathing, I turned to RSM Racing in Mississauga, Ontario Canada. Since it is only a 4 hour drive for me, I decided to let them do the install while I enjoyed a weekend in Toronto.
RSM Ported Components:
This is a stock unit that is bored & sleeved to increase bore from ~55mm to ~61mm.
Upper & Lower Intake Manifolds
These are stock units that are gasket-matched at the union and the head and also opened to accept the 61mm throttle body. Mild runner porting was also done.
The heads were gasket-matched on intake and exhaust side, valve bowl ported and a 3-angle valve job. They also receive new valvetrain components. Intake flow is increased from 140cfm to 180cfm, exhaust from 108cfm to 149cfm.
