How many channels does your dyno software support? Talking with Norm today his software only has 2 channels for o2 sensors so we are hashing that out before I pull trigger on 02 sensors. I looked at that edelbrock stuff this weekend online, I see its about 2200$ for the setup and 800 for the sensors, is there something else that you need from them to make it work, it wasnt real clear reading about it, just part numbers and prices, thanks, Smitty

Smitty is your shop in the Frankenmuth area? It would be great to have a dyno close by to do pulls on before and after mods

Im not up and running but I believe I can use other channels on the dyno and can be configured to do all of the O2 sensors. One other thin that might work for you would maybe be a holley dominator ecu it will log 8 O2 sensors.

Smitty, I run a 1600 gallon underground water tank so that I only need (1) 10HP delivery pump with gravity feed back to tank. I made provisions for a water cooling tower when I built it but never needed it. I am also looking into running 8 additional 02's with readouts for tuning standalone keeping the bank to bank 02's and EGT's tied to the acquisition system.

I've Installed several Dynos (Supflow, Froude , AVL , Sakor among others ) and if they were water brakes . We would put a 1200-1500 gallon concrete septic tank box in the ground , with gravity return for the brake water . Then would pump it up, to an above ground , 2500 gallon tank to return to dyno cell. We use the water for both engine cooling and brake water. If it was me .... I would use an electric pump for engine cooling water and leave off the RWP. We also used the Innovative 02 sensors with analog output to the Data AQ .

Between Frankenmuth and Vassar, 3 miles east of Richville. We are on google as smittyseng in Vassar, our main work we do is building and upgrading transmissions and rear ends, we also do some general machine work , welding and fabrication (not engine machine work) in our machine and fab shop. I build a few motors a year for customers besides my own builds, do some efi tuning on cars and boats, and now plan on doing some dyno work. There are already quite a few places doing dyno work in the area so it would be hard to get much ROI so we are glad to not have to spend 50 k on a dyno and another 25 to 50 for a cell , support equipment etc and we will be happy to dyno customers motors but will be using mostly for our own stuff we build. I have been on quite a few dynos in past 20 years but have never been the operator BUT my partner who owns the dyno has been dynoing for 20 plus years, Smitty

Thats pretty much what Mark R told me too, we just put down 80 yards of concrete drive last year near the building where tank would have to go so not in a hurry to tear it up, I have a loading dock next to shop I could get bulldozed away next spring to place a tank if we go that route though, thanks Brian, Smitty

Good info, Thanks, Smitty

We cut a 6 x 14 hole in the shop floor next to the cell, dug down about 8 feet and dropped in a tank. We cemented over it that way it is easy to service and no fear of freezing. It also has a sump pump and fill system to keep the water at level, before adding that I had a few times with closed cooling systems where we overfilled the tank making a water mess in the shop.

Actually it's a little over 300 gpm using 29.7 ( constant) x diameter (squared) x the square root of the discharge pressure.
