Shane, we have a SF110/120 that could be for sale, like in the picture above.

We have a SF600 and haven't used the SF110 in several years now. If your interested I'll talk to Bill and see what he wants for it.

Thanks Jim. I'm interested, but I have to be careful with my expenses these days. Let me know what you find out.

My email is Shane at warp 12 racing dot com.

Thanks.

Shane

i am absolutely, positively positive you could use a MAF sensor and a shopvac with some sorta flow control and make it work.
i just.. don't know how to make it work. lol



A mass air flow meter doesn’t really make a very good meter for a flow bench. They are cost effective for fuel metering systems because their output is directly proportional to air mass, and they are very fast, which is what a fuel metering computer needs. But the signal is also very jumpy, they are not very linear and need custom "in place" calibration, and the sensing is more or less, pin point. Since they measure mass directly, you need to adjust for air temperature and pressure otherwise your cfm readings will never be consistent.

That flow bench is actually quite sophisticated. My local shop uses one and they say that with the electronics, they see the same anomalies and irregularities with a shop vac that others tell them they won’t see unless the head is flowed at 28 inches or more.

I have a Flow Performance bench that I built. I couldn't be happier with it. It's repeatable as hell and very easy to use. Customer service and support is second to none.

Folks on the flow bench forums call flow bench work "the addiction". It's like panning for gold, you just know there is more waiting under the next rock...

I built mine for around $800, I think. I run 2 shop vacs and I set mine up with an adjustment so that I can always test at the same pressure just to make sure that there are no variables sneaking up on me.

It's fun to work on your cylinder head and see the changes and what is funny is that there will be things that you just know are going to give you huge changes and nada, zero, zip, what a waste of time.

People in the know have reminded me that big numbers aren't the whole story, quality of flow, velocity and low lift numbers are all important.

Get one, you'll love it

Tom

Yep. Thats what Bill said he would take for it.

Its the flow bench I learned on in the 1980's. I spent many, many, many, many..........hours using this flowbench.
