I assumed (hot rod rule of thumb is 15-20) 25% driveline loss due to transfer case, big heavy tires, and stock gears. I think I'll be ok for the beginning but it is close

 

4wd is around a 23% drop from crank hp. So raeally 350-360 wheel hp.

 

He has a built trans that was for his current truck

 

Way too many variables to be precise, but 20-25 is a decent estimate of drivetrain loss. Injector size can be a bit more precise when talking about crank hp.

 

if you have a tan one I have cash at the ready just tell me a price.

I know it's off topic but ya PM is full.

Ps. It's not a ford but I finally finished my corvette and decided to build my truck in the summer so I can have my corvette be my daily as that goes on but I have a complete lightning drivetrain out of my buddies totaled truck that I'm flirting with the idea of buying a screw to slap it in my scab as she sits does the job she's got some mileage though 235k

 

I'll play I guess. Factory F150 4X4, - 99-03/04 ( and without all the variables, factory engines on average) on average has a 31% parasitic loss. FWHP to RWHP. Actually, the argument use to be between 31 and 33%. Yea, it's quite a bit...with the factory set up. Beyond that, yea, that's when the variables join the party.

I know you guys are going after L specs, - but that's where the base is.

 

Completely finished the blower swap minus the cruise control which I'm relocating to the passenger side. Really thinking about doing a detailed write up on this for reference and helping future people out. My setup is a lil different but the framework is identical. Everything is running perfect!!

 

Drivable running? Or what?

 

Yeap minus updated 1350 u joints

 

congrats man, good to see it finished. Better vids will be much appreciated meaning someone filming you driving get some wot passes and takeoffs
