How many CFM does the stock GenII motor flow?

How many CFM's does the stock genII motor flow? Also, what is the volumetric efficiency in terms of percentage? Paolo

If we wouldn't know any better, I would guess Paolo is trying to make his own supercharging system or similar.. Price , price! Two Vipers with a supercharger in each is way cool! Now I just gotta get another viper..

I know my answer may be a bit evasive, but I think it may provide the answer you may be looking for....

For example, hypothetically, if a "stock" Gen II engine is 75% volumetrically efficient, and you proceed to bolt on all types of performance upgrades, the engine now may become 85% volumetrically efficient. By comparison, that same engine in its stock form with a supercharger/turbo may become 110% volumetrically efficient! Everything goes right out the door with forced induction. And of course, even for a stock engine.

Doug, thank you for responding to my questions, I was looking for the exact %of volumetric efficiency for a stock Viper Gen II motor. I have read that an average benchmark is around 85%. Have you ever measured the volumetric efficiency of the stock motor? There is a formula to calculate this but I do not know how many CFM the stock motor flows. Paolo

Paolo,Just come over and drive TOOOFST.Then you'll be looking for diapers not answers!
