im woundering because i read a post on another forum of some one buying a new 2012 5.3l with plans to put a bunch of money into it to and only gets 300hp to the rear wheels. Why wouldnt you just pay the $2000 to get a 6.2l. I know its 402hp at the fly wheel but you dont loose more then 100hp to the rear wheels right?

if you do the rull of thumb of 25% drivetrain loss then this is what i come up with.

403flywheel x 25% = 100.75hp loss
403 - 100.75 = 302.25rwhp

that's just a guess though, it all depends on what rim/gear/tire/dyno you are on.


as for the why not spend the 2k on an upgrade, maybe they can't afford it? i dunno

They probably spent $5000 cash . They could have added $2000 to the loan. This is a new truck. Lot to shop.

Some models aren't able to have the 6.2 as an option.

my neighbor just told me the shop he works for just got a new dyno. I asked him what kind of a deal he could get on using it and he said free. so maby I mite be able to get some time on it.He works at a tractor dealership so no tuning but he said the dyno is the same.

340 bone stock is a good number makes me happy to think mine could put that down. What size rim/tires was that on and gears? Also people always say the transfer case results in more loss, i get this to be true it 4wd not sure about 2wd tho. I am in for some more stock #s!

at the time it was stock 3:42 gears and 22in wheels with 305/45/22 tires(I think...)

I did have a drop in K&N airfilter at the time but I pretty much still consider that stock lol

I could have squeezed a lot more than 300rwhp out of a 5.3 truck for $5000
