Who gives a shit, your data is only as good as your notes with Your bench, Your line voltage, Your elevation,Your track times, guys that try to match flow numbers in magazines or "professional Head Porters" are wasting their time, and are also the ones hooked on CFM or PE only, which will obviously give you a pig port, Ive seen the same thing as Rick, flat mount verse SF head adapter mount will show different numbers with the stock SF plate and a PTS machined plate, another thing every one likes to believe the SF is not temp sensitive but to a point it is.

If I can flow a head on my SF110 and then pay an independent shop to flow it on their SF600 and get the same numbers within 1 or 2 hear and there then what am I missing?

Tom, I always log the temp and r.h with every bench test no doubt my bench loses a few cfm when the garage and motors are hot as hell. I will disagree with your statment that port energy will give you a large port. If you check the graph Chad beats my Dart 215's ported to 232cc on port energy with a 205cc cylinder head that flows nearly the same.

Re: Ported Dart 215 pro1 platinum with port energy discussion 2.0
Considering both are addressed in the instruction manual why would you mount the calibration plate on the adapter when it says not to and why would you disregard the temp gauges on the bench when it says not to?zums wrote: ↑Thu Mar 22, 2018 7:17 pm Who gives a shit, your data is only as good as your notes with Your bench, Your line voltage, Your elevation,Your track times, guys that try to match flow numbers in magazines or "professional Head Porters" are wasting their time, and are also the ones hooked on CFM or PE only, which will obviously give you a pig port, Ive seen the same thing as Rick, flat mount verse SF head adapter mount will show different numbers with the stock SF plate and a PTS machined plate, another thing every one likes to believe the SF is not temp sensitive but to a point it is.

When you use a sharp orifice plate the cylinder below it must be as large as possible so that it does not diffuse the flow.
A to small cylinder shows higher flow.

Re: Ported Dart 215 pro1 platinum with port energy discussion 2.0
Gary, when i tried a flow plate on a Superflow 600 i wondered how it can flow a head on top of the cylinder but not a plate?

Yes they may be a whole new discussion in it's self but I would not know the answer, I tried it just to see the difference and even though my small bench doesn't just much difference at all I still go through the trouble to do it correct.Erland Cox wrote: ↑Thu Mar 22, 2018 7:48 pm Gary, when i tried a flow plate on a Superflow 600 i wondered how it can flow a head on top of the cylinder but not a plate?

Take your plate and put it on the top of the fixture and record the number.
Then take the fixture off and record the number.
Then find the SF formula for using a sharp edge plate and run the calibration numbers.
Then get back to me.

No, not in particular. Anyone.
Just trying to show those guys in Colorado Springs are far from dumb.
MOOO
Re: Ported Dart 215 pro1 platinum with port energy discussion 2.0
Exactly.
The only reason to try and defend the calibration of your bench, is if your selling cfm.
I could care less if my flowz are believed or not.
One guy I did a set of heads for asked what they flow. I said more than they did. LOL
Maybe I should start handing out flowz sheets with that on there ??? LOL
