Both our 45mm stack, AND our filter assembly gained 6hp and 6ft.lb torque at the rear wheel on an independent test set up by Hot Bike for the June 2002 issue. The Dyno test was carried out by Larry hardy of Performance Techniques. I've copied some excerpts of his email to us after the tests. The bike was a Big Dog with a 107" TP motor, running a White Bros, 'E' pipe and a Mikuni HSR42. The base run was using the big 'Ham can' Mikuni K&N filter assembly, the second run with our Flo-Tec and 45mm stack, and the third run with our Flo-Tec filter assembly with the K&N 'Super G' spec filter element.

We make an unarguably, 'top shelf', superb quality custom system, that not only works, but that bolts on horsepower and torque. At about $120.00 per horsepower, it's the best value for money HP that we know of. And it looks good as well.

Hi

This morning I helped set up and test your Flow Tec air intake system for Hot Bike. It pulled very well using your supplied air cleaner over the K&N set up using an HSR 42.......Which I haven`t found anything better until your product.

I`m interested in the Flow Tec system and aircleaner kit for a TC. But the pics I see in your web site are not what I had here for an air cleaner. It was Triangle shaped and screwed on from the front and didn`t have the cover I see around your air cleaner's on your site.

Your machine work is fantastic........for an Englishman ;-)..........kidding !!

Thank`s for your time

Hi,

My name is Larry Hardy owner of Performance Techniques.
Hot bike came down here for testing of one of your products for an article they were getting ready to run
in their magazine. I haven`t found any air cleaner set up`s that would flow as much air as the stock K&N Filter for the HSR 42`s. And for the price I probably won`t.

My test`s showed 6 lbs of tqe and 6 hp gain using your Flo Tec system over the K&N filter. There was no tuning involved in these particular dyno runs. With some fine tuning there should be a bit more. tqe and hp to be gained.

 

Hi Larry,

Could you please tell me which stack/s you tested (12mm stub, 45mm Midi, 105mm Maxa, 130mm mega)

Regards
Robert

 

Hi Robert

I used the short 12mm 45mm midi both did well. The air cleaner set up did very well.

There should have been a loss adding the air cleaner but there wasn`t. I don`t know if the longest 105 or 130 mm stack was here. There was only three here we tested. The longest stack actually produced the best hp. But there wasn`t any place to put your leg. (depends on your seat height, length of your legs and the position of your foot controls ... ED)

Hope this helps

Good luck with a great product
