Brent I hear you

My thought was the 2500 in a Cobra is a pretty typical cruising speed in fourth, ....but I get your point that nailing the throttle in a cobra (with torque multiplication through at least the rear axle) is a lot different than a direct driven Dyno Water brake, so I understand you!

I've worked with a lot of the F.A.S.T./N.M.C.A. drag racers that are very tire limited (because they have to run OEM stock appearing 70's skinny vintage tires) many of these guys really have to come the line not much above idle and many stutter ramp the ignition to "traction control" the launches... but I know many of the High torque/Low RPM combos (like 455 buicks and 440 mopars) do get dyno tested at lower RPMs with fairly tight converters. But most of them run Vacuum secondary OEM carbs like q-jets and thermoquads....so even if you load them at WOT the back barrels aren't even opening.

Do you work with any of those guys? It's really interesting the power they get using OEM heads/Intakes and only 2.5" dual exhausts
