could somone run my combo on there desktop dyno for me please.

the cam is set strate up I have eagle I beam rods and speedpro forged pistons. This is going in my 76 f-150 4x4

 

Valve size for a more precise calculation?

 

This is what I ran with a random exhaust, and valve size. Also I am not sure if your intake is single or duel plane

sory for the delay. the valve size is I 2.05", E 1.60", The ports on the intake are 210cc and the exhaust is 75cc. It's a duel plane intake, and lets say 1 3/4" x 18" primary hedders with 3" exhaust all the way back with flowmasters. I'm living at 7,200' ellivation right now. thank you for all the info.

 

the exhaust is 175cc but damn thats a serious 351w throtle jockey.

Desktop Dyno isnt the most accuarate measure even for a real dyno it has to be setup pretty good and the right programming for each vehicle. This is a rough estimate as you all probably know.

 

My NX hitmen nitrous kit just showed up. It came with jets for 100, 150, and 200hp. I heard somwere that NX rated there hp levels at the rear wheels. This truck should get moving nicely even with the 100 shot.
I found that my school (wyotech) has a engine and a chassie dyno in my roommates class. It will take me a few weeks to get it all set up but i'll post back with the results. at this elevation (7200') they say it brings the avrage hp down 25%, the air pressure here is somewhere between 11 and 12 psia.
