Moving 72lbs per minute... that should support 700whp right?

49lbs per minute supports 460whp.

What is the exact formula for that? How does this work? Can anyone help me out here?

The benchmarks are used on SRT4 motors just incase that's a question.

You know of a 700 whp SRT4?

The rough equation is 100 hp for every 10 lb/min of air moved. The exact numbers are widely dependent on humidity and temperature.

There's a couple... yea

That's a wild amount of power for a little car like that.

You've never seen some of the ecotech drag cars making 1000+ hp?

Maybe I'll build a sunfire convertible with a 1000 hp ecotech engine...

Only if you post a vid of the boost gauge passing 40 psi.

720 hp has to suck on FWD. get those babies spinning and there goes your steering...not to mention torque steer. hot damn

it depends on engine variables. check here:

scroll down to where you see:

theres a good equation to figure it out.
Wa = Airflow in lb/min
HP = horsepower
A/F = air/fuel ratio
BSFC/60 = brake specific fuel consumption ÷ 60 (to convert from hours to minutes)

for a 720 horsepower engine:
Wa = 720(horsepower) * 12(air/fuel ratio) * .55/60 (BSFC/60)
that comes out to 79.2 lbs/hour.
