Question about dyno tuning.. - ZR-1 Net Registry Forums

Vette73 · 03-13-2016

Had a few cars put on the dyno over the past few years....Does it matter if they are running a fan in front of the car ? Is this done to simulate outside air coming into the car, as if it was moving down the road.?

Reason why I ask is because I dynoed both my vettes over the last few years ( ZR1 last week) and both times they did not run the fans....I would guess if you had a ram air effect car it would effect the overall numbers,or, should the fans be running no matter which car was on there?
