Who supplied the heads?



I'd rather not say...that WOULD be taking a jab at someone. Chalk it up to not all flow benches agree. Or some aren't even close...LOL!

Thanks Brian for that info...I appreciate it.



Really? That's not taking a shot it's reporting your findings. Which after some light work, you got numbers similar to others. I guess people should become comfortable in buying things and not getting what they pay for. You clearly didn't get what you expected from the provider, correct?

To me, it's more about finding out if your stuff is an anomoly or they have a happy bench compared to others. Look at the hughes numbers for an RHS X head with a 1.92... That's some happy numbers, 263 at .600 with a +/- 6 cfm variation. 275 at .700???
