just wodering how much hp
it this u might say

8.8 flywheel
under drive crank pully
aem pulleys
header
sri
exhaust

to the crank
and to the wheel
just a rough estimate...

 

On what engine.

I'd say a big N-O to the 8lb flywheel and crank pulley. If its your typical F22..probably 7-10hp more than what it puts at the crank. Maybe 3-5 extra at the wheels.

 

Whooo ..... you have a UR underdrive crank pulley AND AEM underdriven accessory pullies?!? I'd get the AEM's out of there if I were you. If you have enough power from the alt., I'd still put an OEM size water pump pulley on.

My guesstimate would be about 5 HP higher than BCK's for both measurements ....... but then again, he's right to ask what engine this is from. Different engines make different gains.

 

If its the F22B, asssuming, as its a 4 banger 5th gen, the water pump is timing belt driven.

 

I didn't know that .... thanks!

 

A lighter flywheel and underdriven / lightened pulleys wont give you any more power to the crank. They basically help you "reclaim" power to wheels that the heavier parts had taken.

I'd wouldn't use AEM pulleys and an underdrive crank pulley. Both are designed to underdrive to a somewhat tolerable limit, so I would assume the pairing would severly underdrive accessories. Go with one or the other. Or try a lightened crank pulley, that isnt underdriven, andpair it with the AEMs. Almost seems the best of both worlds.
