I'm still thinking about coming up with a cabinet to house the flow bench with the air source docking into the Flow Performance setup."

" ..just thought I'd let you know I got my velocity probe yesterday. I connected up to the [FP1 pressure sensor 3] and away it went (I am sure you would expect that any way). I am really pleased with my purchases from you, and building my own flowbench has been relatively easy thanks to your help.
Many thanks,  Rich (a very happy customer!)"

"Due to work demands a flowbench was finally required in my arsenal of tools and to say that the FP1 has simplified life in setting up, data capture and constant. accurate results is an understatement. Not only is it all of the above but the customer service has been second to none in getting me up and running double quick time. One of the best investments I have made in a long time! Here's a picie of our homemade bench close to it's final stages..."

"We have a [very nice flow bench] in our race shop but I prefer to use our FP system flow bench"
Gary D, Wicked Motors, Maryland
"We love the [FP] system.  It works great!!
We're building up a no lag SR20det right now for our demo drift car. Many of our heads we have worked on with it have showed substantial improvement.   This is leading us to get a 4 axis CNC machine so porting heads can be done. Combining this with our fluid Customers love how it shows the improvements.  Just finished up a 4g63 stroker engine designed with stock cams and modified ports to make 450hp with stock idle and drivability.  Also one of our engines is on the cover of Performance BMW mag this month.  It's nothing special but it's the first time one of them has been on the cover."

"With regards to the bench it is absolutely fantastic; it was extremely easy to assemble and has worked �straight out of the box�. The calibration was [nearly] perfect on both the Cal A & Cal B when we checked it with the included orifice plate and comparing the flow data results with a company that produces CNC Heads using a [very professional flow bench] the results overlay [near] perfectly. Testing a head is simple and fast and the Shipping to the UK was extremely efficient."

"... I would like to say that I absolutely love my flow bench.  I was a little leary about dropping 1200 bucks at first, but now wonder how I ever justified spending all that time on heads with no quantifiable results.  I've learned that some of the simplest stuff makes the biggest differences, and some of the most time consuming amounts to nothing."

"You are making an excellent product..."

Thanks Alot!

"I took my [FP Basic 2.0] bench last week to a friend to do some work on his heads. [While his shop vacuum] only had 6� vacuum available at max lift,the results were well within a narrow margin  of my own test head.

I was very much pleased."

"I had purchased your DIY flow bench kit [in 2011].  I am more than pleased at the results.  Your after sales support was so help full in directing me in the right direction.  I have used this flow bench in the development of performance vintage motor cylinder heads and manifolds. It has allowed me to gain much needed expertise in providing my customers with the best available engine components. Many times I have check it against other flow benches and it has matched every time.
Thanks again for you product and your support."
