Proform 850 dialing it in closer
Sorry for the derailment.......
Wow...... still pretty high up there.
What will be the nearest track?
No Derailment.
If any one was, it was me being a grump!:)
High? it 2000 feet lower:D actually i haven't checked what the elevation is there.
However Hypoxia is still the closes track.
And I will still be helping with what ever improvement that goes on at Hypoxia, anyways. It will just take me a little over a Hour 1-1/2 to get there instead of 5 minutes.
So, me and my car, while still be grasping:eek: for breath at 6600 feet.:D
I calibrated my bench and threw my head adapter on. Threw my "EPOXY" Ported head on the bench and did a test run.
loud, screeching, and crashed above .300 lift. At 600 lift it gave me back 20 cfm.
Figured out that my head adapter bore was not center on the combustion chamber!
Called my machinist friend to explain the problem....... He said, how can that be, I centered it exactly center on the bolt pattern(It uses two dowels and two factory head bolts to clamp the head to the fixture) flip the head over and for the first time in my life.....I notice that the bolt pattern is NOT centered over the bore:wtf: so now he is going to have to re do the hole top plate. Just for reference, it shifted the bore/cyl 1/4" to 3/8" off center.
Just goes to show how much smooth entry(Pressure recovery)has to do with the hole port.
It crashed at 223 cfm and only made 231 at 600 lift. With my original bench and flow adapter it flowed 271 at .550 lift.
This is a grate example as to why you have to do a bore notch, if your using a large intake valve in the small 273 bore eng.
So back to packing up my garage waiting on a updated fixture.
