I've heard about the live maf reading (the highest reading during a log) being turned into crank horsepower example: 35lb/pm=350 hp some people have said it is fairly accurate is this times by ten rule of thumb true or just a myth?

 

I have heard that too but don't put too much weight in it as we all talk RWHP here

 

speaking of rwhp what kind of drive train loss are the ls-trucks 12-15%? or are they more?

 

i think more like 18-22%?

 

hell if thats true then my little 5.3 is putting out 460hp ahhaaa

 

I dont think that figuring your drive line lose out at a percentage is correct say you make 100 hp you would lose 18 to 22 hp and if you make 1000 you lose 180 to 220 thats not happening.

 

well how do you figure it out then??? to my knowledge its always been by percent. I believe at one point chevrolet had info on the silverado ss for the AWD version and they said 19% drive train loss
