915 Head Flow Results

Had my set of 915s flowed. I bought these a few months ago from a member who had bought them from another member. Dont know who ported them.

Here are the #s

I

.100 67.3
.200 137.9
.300 210.4
.400 264.3
.500 265
.600 270

E

.100 47.6
.200 101.9
.300 134.6
.400 179.8
.500 198.3
.600 211.5

They were flowed at 28'' with a 4.280 bore. I dont know if the exhaust had a pipe or not.

Anything stand out or look funny on the numbers?

Would the flow #s change much when used with a 4.375 fixture? If so, more or less, usually?

I'll have some numbers to compare as they are flowing my BS heads that were ported by Dwayne.

Thanks

bigger bore would unshroud the intake so that I'm pretty sure would pick up some , adding a pipe on the exh I have alsoseen picked up flow .

they look good , I'll PM you my address where to ship them .

I`m no expert but those look like some descent numbers and if I remember right, my Ed Vickroy ported 906`s went 278-279 intake and low 200`s on the exhaust and pushed my dart to 10.40`s at will in my daily driver till they cracked.

Did you have them cc'd on the chamber side?
