diesel hp rating for pounds per minute

I thought about that, but I don't know of any forums that I could go to for that.
 
k ....lol...

I still am wondering how you get a hp rating for a engine if you change turbos

Somehow they come up with a number to figure this out.

Thanks guys for the help so far....:woohoo:
 
Also if a turbo flows 69 lbs per minute what hp can you get with fuel only at the rear wheel?

You use the same equations you do with gassers, you just use different BSFC, A/F, and VE values.

From Garretts website:

Where:
· Wa = Airflowactual (lb/min)
· HP = Horsepower Target (flywheel)
· = Air/Fuel Ratio
· = Brake Specific Fuel Consumption ( ) ÷ 60 (to convert from hours to minutes)

If BSFC = .4 and A/F=a smokey 18:1 then HP = Wa/(A/F*BSFC/60) = 575HP max for 69lb/min (470 would be almost smoke free)

How did you come up with .4?
