Mustang MPH?

Tim,

A good 396 will make approximately 580 (1.45 to 1.5) on the Dyno. A good 427 will make between 600 to 615 (1.45) on the dyno. You can take several of these cars to mine shaft or factored tracks and put up 9.70 numbers. Racers have worked for 20 years to get these numbers on the track, however their baseline dyno power multipliers are still 1.45 to 1.5.

When it comes to power, I'll gladly swap a Cheverolet Big Block for your 331 cubic inch Supercharged motor.You aren't denying the power number of 1.8 for your motor! Are you?

How much power are you guys making with this CJ motor Tim? A CJ has already put down a 9.78 in only it's second time at a sanctioned event. How much are you guys still holding? At this point, time is on our side. You guys have barged into Stock classes and had your way. Now we'll sit back and watch the numbers.

How much power is that little 331 Supercharged motor making? You can do it.

The factors I calculated are a HP/cu in basis. Re-reading your previous assumptions I think you are thinking in HP/rated HP. Relative to engine displacement the ratios are legit, relative to factored HP we're all guessing and I think anything over 700Hp (with the stock pulley) is going to be a stretch.

Second sanctioned event after a year of track testing/development. These cars were not slapped together overnight.

Now to expect that any new engine/car combination will evolve at the pace the combos like yours have is absurd. Anyone with the knowledge gathered over that 20 years of development that you mention can apply that to a new engine and within a few months be running at a near equivalent level of optimization. You see this demonstrated when guys like Bob Shaw find some obscure combo that no one cared about, build one and run circles around everyone in its class - first time at a sanctioned event.

I don't know first hand what the limit is for these cars, i can guess like you (actually my guess might be a littel less dramatic). Probably even agree that these cars will justify some HP and earn it in the near future. I was hoping to see some entered in Gainesville to run for class (haven't looked to see if there are any Chevy hitters entered for it to matter).

BTW - no response from you regarding the Hemi's? Don't wanna bring that up as it doesn't benefit your cause?
