Ive balanced somany cranks assys I cant even think of how many, many machines do a ok job some do a great job and nomater what machine the balance job is no better than the person doing it. some machines dont get down far enough, just good enough...and some guys dont like to spend the time to do it right even if they know how. or they try to sell you a stock balance job, or a street balance job , or a prostreet balance job or a race or super race balance job. well it's either balanced or not when you come uppon somebody doing all these different balance jobe get your **** and run. ive been without my balancer foe about 10 years now and I miss it dearly,I only do my own stuff nowdays in my shop, but that is one peice of equipment that I nolonger have my fingers on that I wish I still had. I dont relly like the first unit shown, but I havent used it, it would be nice to see what it really does and the repeatability. I can already see the operator dosnt know how to do it right....so sad.and the customer hasent a clue it isant what he thinks it will be.

i do like the looks of the one tony posted. wish I could afford to get one again. I have major trust issues sending my stuff to any body else...when you have fixed oh somany other shops **** ups...you dont trust much of any body. I have friends that I thought knew what they were doing...till I sopent some time in thier shop and saw first hand... they didnt. so sad. I miss it as much as racing. and I still have a few of my own motors to do...I almost have enough equipment in my personal shop to do it all...but not a balancer.errrrr, I miss the flow bench too.

Neither a flow bench nor a balancer is outside the reach of a HMT guy. Here is my flow bench

and the software click for full size.

as always awesome work tony!! remember you need to calibrate every day sometimes multiple times depending on the weather. always make sure there are no leaks,some people use a cork pad some a foam pad. either way just be sure to have it sealed to the machine. as always use a radiused inlet .prefurably the same one as that can change flow quite a bit. I tried studs and stuff on the ex side but it didnt change much at all. but I do think atleast a 4"-6" long stub wouldn't hurt and may keep some turbulence out of the port that wouldn't e thee when running. some people use strings to see what the flow is doing, pr a smoke probe, but remember probes can change whats is really going on...and show you something that may not be there. Ive even seen valves with built in probes going down through the stem. a lot can be learned with a flow bench and a lot of good parts kept good parts as you know the rong port work can make a expensive head...junk. keep up the great work !! I miss having a flowbench as well as balancer.

No I don't. Calibration is not needed. Sensors measure the environmental conditions and feed directly into my software along with the measured pressures. So the air density is known at each and every data sample. Summer or winter, the results are always the same for a given port.

Here are some details from a previous post Home made horizontal milling machine.

I didnt have all that fancy stuff just the basic superflo flow bench.

I didn't have the fancy stuff in the beginning but I always corrected for temperature, pressure and humidity. Right from my first device I avoided the idiotic percentage system foisted on the world by the Superflo designs.
