I have a stock motor 2v with a kenne bell 2.1/Mammoth inlet. I want to know if i will make more power with the stock heads and cams Vs aftermarket heads and cams. Im leaning towards the latter but have heard due to the small blower and larger heads the velocity drops off vs the stockers. Any thoughts?
Still waiting to see a dyno sheet of someone loosing power because of ported heads and cams. May change the power band but you are changing cams its expected...... The D3V
Its possible to lose some boost pressure (psi) due to the heads/cam flowing more air, but you shouldn't lose power.
That's what I figured. Plus with the mammoth setup it has a 9psi pulley (Yes I double checked the size) and it made over 14psi on the dyno. The max power was at redline so it never dropped off.
