My $ 50 Flowbench - 1st design
After reading about Graham B's flowbench on the TS site, it got me thinking that I could do very similar for not alot of cash. Well, so far I'm all done for under $50. After doing a bit of reading on the net, I decided my first flowbench would be ultra basic, a single box, no calibration plates, just 2 vacuum motors on individual switches, a simple manometer made from plastic tube and a smaller one I could use to probe ports. Nothing fancing but something that I am able to compare heads against one another.
While I cannot compare my flow rates to 'known' values, say H20 or Mg, I can still plot me results on a basic graph to insure that any porting actually does give gains.
Anyway here is how things look, I'll get some more photos of the 2 manometers and probe tube if anyone is interested. The more I play with this, the more things get interesting. I already have plans for the next one, 4 motors, calibration plates, relocated motors, (for noise reduction) and adjustavle orrifaces for inlet, exhaust and so I can flow my brothers ZZR speedway heads.
Items I used
Chipboard + laminated board.
2 vacuum motors (1300w)
5 mts plasic tubing.
Adhesive foam (for sealing)
4 cut down head bolts
1 double powerpoint switch
Chipboard screws and liquid nails.
From behind, twin 1300w vacuum motors.
Inside the box. nothing pretty, sealed and internal with bracing.
Top of flowbench, long enough to fit whole head on and do one port at a time.
Lots to play with...
As you can see, it's all very simple but it works. I'm now able to port and flowtest heads without having to leave the comfort of my shed.. Yep, one more thing to take up room...
Hope some found it interesting..
