Killin it. Right on.
How much advance in the cam ? Trap rpm? What's been done to the heads?

4° advance. Turn it 7200 on 1-2 shift 6800 2-3 shift. Trap rpm in the quarter around 7200. Heads have been fairly well ported, but not my best. Flow 265/185 on a SF1020 which would be close to 280 on a SF600. I have a junk head that I did some experimenting on that hit 280 on the SF1020 which would be like mid 290s on an SF600. If I get ambitious I'll work over a set for next year. I plan on swapping the cam this week for a custom ground Bullet.
Old cam specs 252°/252° @ .050 164° @ .200 108 LSA +4 .528
New cam specs 257°/260° @ .050 172°/173° @.200 108 LSA +4 .563
 
@skrews Excellent job, well done. What does the car weigh?
Oh, rear springs are?

Why such a difference between the two flowbenchs. Dont they calibrate them.

For what ever reason thats the difference between those 2 models according to guys that use them both. Back in the day World products used to provide flow numbers off both benches.

Hmmmmm. I don’t like that.

I know if a SF 600 was using SF correction software it was 10% higher than my bench.

If that same bench was using Audie software that bench was within less than 1% of my bench.

It has to be something in the correction software doing it.

When someone wanted “SF” numbers I had a built in fix for it that raised all my numbers 10% with one keystroke.
