new direction:

i am porting the inlet to 3 1/4" x 3 1/8" ther is enough material there to open it for larger TB.

this is the work in progess now. i need 833 -1000 cfm and 75mm ain't gonna cut it.

that is a 4" 80 degree elbow and a twin 57mm throttle body.






this is using the 11" short runner intake i made. i got the length wrong in previous posts. her is a dyno sim of the results. these are only theoretical until this spring's dyno.

this is with the cams left fully advanced as they are now with the inlet pictured


this is with the cams left retarded with the inlet pictured




so once again we shall see. i removed the short runner becaust iot didn't work well. but the real problem was the cams advance. dyno in march i think.

 

 

 

it needs to be mentioned that this is with headers and 20" of pipe then open. i have supertrapp baffle only mufflers on the way. there will be no real exhaust under there. they will exit directly under my seats. muffled a little for the street then open for the dyno and track.
