Dunno what hes on about. Probably cooking up some calculations based on your 1/4 mile time, cam specs etc but no doubt underestimating the weight of the car and forgetting that you only use 3/4 throttle at the track and short shift.When Mopar Muscle magazine in the US run their annual dyno comp (used to be engines only) now its chassis dyno at one of the big shows over there they call it the 'Numbers don't lie" dyno shootout. Could be a good name for ours if it becomes an annual event, with the Cuda as the car for the 'Numbers don't lie' flyer.

Its always the way with dyno's-some say it's being generous, others say its being tight, but realistically we all know the dyno is a tuning tool. You could take a car to a different dyno every month for a year and I have no doubt you will end up with 12 different readings, and there would be at least a 25% variable from highest to lowest. Its just a load of fun and an opportunity to get an idea where your Air/fuel ratio is at regarding tune, but even that is tune at those particular circumstances-ie: hot moist summer type air, stuffy corner of workshop etc, take it to Mopar Sunday and put it on the dyno outside in fresh crisp dry winter air and you're going to want more fuel for sure.
Maybe the Cuda is a little lean and the tune was optimum for the thin air we had so it loved it and ramped up a decent reading, as did Daves ute. On the contrary it was clearly obvious that a few of the other cars were showing quite fat AFR's which was evidencd by them being noticably down on HP from expectations, but also backed up by the black smoke they were blowing up the wall. John's red 265 Charger went from 190hp to 220 with a jet change-a fairly decent jet change and second time around didn't blow any black smoke and AFR's were much nicer.
So fatten the fish up and go run an 11 Greg?
