I have an 01 4x4 cummins dually that has been turned up 75 hp with a k&n airfilter...355 gears...new high performance injection pump fast for a big truck

WIll I keep up with my brothers 02 Ford powerstroke 4x4....373 gears but with 315 tires...also turned up 75 hp as well....he says he wont run me from a rolling start only in the quarter

 

It'd be a good run, but really its up to you two, and how you drive. You can have the fastest truck with the most hp and torque, but if you can't handle it you can still lose. Be safe whatever happens!

 

75 hp added is about the limit of your stock Tq Converter..... and without billet shafts, I would not build boost on the start line (5-7 psi might be OK).

If your still running stock tires (265's) and launch in 4x4, I think you would take him. Does he have a 7.2L or a 6.0L engine? 6.0 is faster, when they hold together.

my 02 4x4qc with 275 inj`s and a puck,on 265`s,ran a 10.25 eighth,,my buddys 7.3 powerstroke 4x4 crewcab on 305`s with a predator 100hp program ran a 10.20..................so thats both trucks at about 100hp gains with him running a little bigger tire.....bama
