I have a quick question, say with a stock truck your losing about 18% hp through the drivetrain. If you supercharge that same truck are you still losing 18%???
Yes and no. Your power is still going through the same drive train with the same amount of drag or robbing the same power from the engine. So that remains approx. the same. Now even though a SC creates more HP. It also robs the engine from some power to turn the SC. It's just that the SC creates more HP than it robs but I would guess that the percentage changes when you add accessories to the engine. Someone will chime in and make your head spin in a little while.greatone61 said:I have a quick question, say with a stock truck your losing about 18% hp through the drive train.

Well that's a 15.3% drivetrain loss in stock form. If the percentage holds true then it should be 622 flywheel hp after the S/C. :dontknow:greatone61 said:Here is my problem:
2006 SRT-8 Charger made 360 rwhp stock....425 crank hp.
Supercharged it made 540rwhp. Only thing that was changed in the drivetrain was a Limited Slip Differentrial. What do you guys think he's making at the motor with the supercharger?

I think it's safe to say he's between 605 and 622 fwhp, lol.greatone61 said:Thats what my and my buddy have a disagreement on...he says you don't do the percentage calculation you just add the stock hp loss back in and you get your new flywheel hp. So in this case the stock hp loss was 65, so the new flywheel hp would be 605....I still think thats not right......
Nowwhat said:the drivetrain loss percentage will begin to decrease at a certain point.....
if you are losing 18% at 800 crank hp
you will not lose 18% when that crank hp is boosted to 1200 hp
Bone said:I agree, it's not completely linear with loss. The percent may be somewhat close but a little less (in percent). I imagine there are plenty of variables involved.
