Well that flow bench right there was within 2cfm of the flow bench Jeremy and ten speed used for butch Kemps sb2 motor.
The same motor that Dynoed in the area of 1050hp and by the time it was put on a dyno in MI a day later it picked up 50hp.
It might truly be the engine builder here or something he's missing....
Blaming head flow #s against someone that's makes 800 hp sbs like changeing his underwear is Balsy especially when The TOP engine builders praise his work.
Uratchko or BES would've seen this problem without bolting them on i would imagine.
