Anyone flowbench the trickflow 190 heads yet???
I for one have learned a lot about head flow numbers in the past few years. So to say flow numbers don't mean anything certainly isn't true. It's just like any other spec. A comparison. Looking at it as it makes no difference, you may as well not ask about camshaft specs, valve spring specs, what compression ratio this piston makes with what head........Everyone here in the mainstream of posters shares information. I have a couple extra added to my list now though.
Frankly, imo you’ve totally missed the point of my posts as well as Jesse’s.
When you buy a set of heads that come from the manufacturer already CNC ported....... they’re going to have VERY little variation from head to head.
If you see wildly varying flow numbers.....the difference is in the bench, not the head.
So, if you had ten sets of numbers, with ten different results...... which one would you believe?
This is not at all the same scenario as an independent CNC head shop that’s buying bare heads and doing them in house...... and you’re trying to compare results from different head services, where the numbers from shop “A” are wildly different than shop “B”.
They may or may not be different, since it’s not the identical product.
So, in that scenario having both A and B heads tested at the same facility would eliminate the variable of different heads being tested at different facilities.
The TF site has flow numbers on their heads. IMM posted his results.
More test results aren’t going to change what the heads actually flow.
