lbs/min question

[Yamahaulin]

Does anyone have some chart or estimations on how many lbs/min equals x amount of power. My car on 16psi does 38lb/min. I had it to 20psi but didn't log lb/min the turbo is leaking oil through the seal and into the intake side of the turbo, my intercooler is covered on the inside so i backed it down till i can get a PTE 5857 turbo.

I don't believe there could be a real accurate chart because although airflow determines power, there are so many other equations that go into this. What type of mods along with airflow determine power, so unless you were running the same exact mods as someone else a chart won't really help you.

Think about it, running 93 octane pump gas with say 38 lbs a minute = X power

But running e85 at 38 lbs a minute = Y power

Do you see what I'm saying or am I just rambling?

rough estimates when you get over 40 lbs/min is 1 lb=10hp... But i doubt a 16g pushing 20 psi is making 380 horse..

Makes perfect sense.

I doubt a 16g could make 380, but i don't have a 16g i have a t3 50 trim.

The 16g has supported 500 WHP on Curt Brown's 1G and has made over 400 WHP for many, many others, so 380 is easily feasible.

The "1 lb/min = 10 HP" rule of thumb is decently accurate. It will usually get you in the ballpark at least. If your airflow number is accurate, then you're probably somehwere around 380 HP at the crank, so somewhere in the neighborhood of 300-310 WHP.

But as Nati0nalxCrisis pointed out, there are too many other varibles when it comes to determining power output, so we cannot accurately grade HP using airflow alone.
