I was wondering what the flow difference is between stage 2 track eliminator & street eliminator heads. I have a set of street eliminator heads that have the valve bowls cleaned up & combustion chambers polished(66 cc's),ports untouched. How much power can be made with a set of these heads in the above described state, given the right camshaft,compression, etc...
Richard Mann down in Tx has a 535 that made 867HP w/ SE's My Motor's never been dyno but makes enough power to go 9.7's with SE's They are still a good Head. If Buying new I would get TE's but I won't make the switch as I don't think they would show much on the timeslip.
Then it's possible to make 750 HP on nitrous, with street eliminator heads. the reason I ask is because I plan on building a healthy(street driven) nitrous motor.
We can typically pull around 330to 340 cfm out of the SE stg-2 head using the 2.125 inch valve. We can typically pull about 360 cfm out of the TE head using the larger 2.26 inch intake valve. Either head is capable of producing lots of power. Jim Burek P.A.E. ENTERPRISES
Re: Re: Difference in flow(track eliminator & street eliminator when you say 330 to 340 cfm is that in full ported form.
750HP is a cake walk with SE heads and nitrous with street friendly compression. I have dyno sheets from my 10.5-1 462 with home ported SE heads and fairly small solid cam. PM me your e-mail and I can scan my dyno sheets and send them to you. My motor made 814HP and 826ft. lbs. long before 6000RPM before it was wrung out completely with 225HP nitrous jets. Pushed a 3850lb. (scale weight) street tire car to over 142MPH before I quit using nitrous. In the 2 years after I gained another 8MPH on motor alone and think it would have gone over 150 if I decided to spray it then. Nitrous is your friend, look more at the exhaust flow not intake flow on heads when using nitrous. My heads only tested at 315cfm intake and still made good numbers.
Re: Re: Re: Difference in flow(track eliminator & street eliminator That is with quite a bit of porting done. And incidently, those numbers would hold true on the stg-1 alum heads as well since they use the same intake port configuration as the SE stg-2 heads. It's not really doing anything to the cross section area though. I have'nt done a set yet with a larger intake valve, could be some more flow there. Jim Burek P.A.E ENTERPRISES
