: Pulley combo with ported heads/cam/headers

With making the combo more efficient I would think it would be a good idea to change the pulley combo. I'm running a 10" lower now but after the next round of mods I figured I would do a 9" lower and 2.55 upper/ported snout or something similar.

a 9" and 255 upper is spinning the blower extremely fast. I'd reconsider.

That combo has a high likelihood of just building more heat and not more power.

Port your blower,snout and TB. More power without the heat

I'd say just keep the 10". You'll make a fair amount of more power and it will put less heat & boost on your setup
