Anybody know what stock runnercc size is also?

Not really sure, but you can probably get a rough estimate by checking your MAF to see how much air you're flowing at any given time. Then you can just do teh math to convert it from kg/h to cfm.

I'm sure that doesn't really help much, but that's how I would try to figure it out.

Without using the MAF, you'd have to know the VE and hp at max rpm, then calculate and adjust for barometric pressure and air temperature.

my engine isnt stock anymore. so i cant do that and wouldnt you need some type of tuner to read that? which i also dont have. but thanks samseed

i didnt think it would be this hard to find this out. Samseed, does that tweecer of yours tell you your cfm?

r.barn

engine cfm formula.

( ci X rpm ) / 3500 = cfm

( 302 X 6500 ) / 3500 = 560 cfm

thanks r.barn. had no idea it was that much

those are "theoretical" lab numbers of course.
