So I was crunching some numbers today during linear data structers class. I figured that when I do my 408 stroker, and i put on my twin turbo set up that i should be running about 680 horses. This is based off the calc. that the 408 is putting out 400 hp and around 550 torque (thats in the ball park correct?). Heres my calculations:

if(408 stroker == 400bhp){

boost = 10psi ;
1psi boost = 7% hp;
400 * 70% = 280;
total horses+= 280;

total horses = 680;

return yes?
} // i think that should be about right

 

Oh yeah, twin turbos!!!

 

So you ARE going with a 408 after all. Sweet!!!

 

haha no i got the bike. But im still going to get a 408 down the road. Prolly next year

 

mmmmmm pic's?

 

Its going to depend on how efficient the turbos are that your getting. But by my math
your in the right area. I assume your talking flywheel horsepower ...... if thats the case
you would be looking at around 543 wheel hp.

 

LOL I did the same thing this year, got a new bike. what did you get?

 

Over 500whp in a 4wd 2nd gen ram would just be totaly scary

 

Stock 46re with 9.25 & lsd in a 4x2 sees about 25% driveline loss. To handle the power your going for, need to beef up the tranny with bigger shell, more clutch plates, more gears on the planetaries if you want it to last longer than a few miles
That & the 4x4 transfer case, expect about 26-27% loss
Id guesstimate 680hp crank would put down 490-500rwhp in your truck. Lot of variables in the motor, driveline, boost & tune but its still fun doing desktop dynoing

 

well as of right now i have a pure evil tranny from Dr. Evil trans. Thats good for 500hp, but id obviously have to upgrade even further. But yeah Indy im with you on the percent loss.
