How much hp should my 300ex be pushing

[wantablaster]

I was wondering about how much hp my 300ex should be putting out at the crank and at the wheels?

wiseco piston .020 ovewr with 11:1 compression, milled head, ported and polished( trail port),3-angle valve job, fmf megamax slip on, web cam springs rocker arm and stage 2 cam, kn filter , high performance cdi, wheel spacers, 14t front sprocket.

And how much should I be looking at when i get rid of my megamax and put on a white brothers header and Hmf silencer.

I'd guess mid 20's. You didn't indicate the CC's. I'm assuming stock bore and stroke with 11:1.

Im a tard.. I should have read your signature.. lol.

The 0.20 won't really make a difference.. but the compression, cam and porting helps a lot. Mid 20's is good power for a 300ex. Stock it's only about 15hp at the rear wheel (18hp at the crank).

You'd get a few more ponies out of her with dyno tires on. You loose power on a dyno with knobbies.
