Dyno's are for queers!

Looking good so far chaps!

This may have already been discussed, but have you calculated exhaust air (as in air out of the dyno) flow compared to inlet air (as in air pumped into the dyno)? I had one instance recently where a dyno cell was being pressurised that much by the fact that the exhaust couldn't get the air out quick enough, which was actually backing up the inlet fans, pressurising the cell and actually stopping the inlet fans from doing anything.

Easy fix was to open a rear door in the dyno cell. lol
