im building a 99 cobra so far i have 4.6-5.0 stroker kit from eagle with h beam rods and 9.5cr dishtop pistons, my heads are port and polishd with a valve job, got ferrea stainless steele valves, comp cams valve springs and retainers, and also a pair of comp cams with .475 lift on the intake and .450 lift on the exhaust, anyone have an idea of what my dyno numbers should be around

 

What's the duration on your cams? If it was an all motor build, I definitely would have upped the compression ratio on your pistons to about 10.5:1 . You should see close to 400 rwhp on that set up, if it's set up correctly lol...

 

you building it for boost or all motor? prob not much over 300 with that setup. add some boost to that low compression and you got a good running car! yea we need more info on your cams

 

exhaust durration is 276 and and intake duration is 278 i was ether planing on putting a eaton or possibly two small turbos

 

i thought i heard eagle was garbage?

 

The cams you got are pretty radical NA cams and will not do well with any type of forced induction set up. Change your cams if you want to boost the car. Too much overlap...

 

+1 .... btw, supercharger cams generally work very well for turbo cams.

 

idk what to do really i already have my pistons and everything im not sure if i should just buy new pistons for a higher cr.. but iv had a few ppl tell me it was an okay setup, thanks tho
