you can look at my sig and see what i have going on but i am going for a set of injectors next but what is the best recipe for making upwards of 500 hp and keeping drivability daily and for long trailer hauls as well as family trips i have my hx40 refulated at 45 psi i am not exactly sure what it is capable of before just blowing hot air, i am also going to do head studs,gaskets,fire ring or what not so what else do i need to make my power.

 

First off have you built up your trans? With your current mods you can burn it up let alone adding more power. Other wise you want to post this question in 5.9L 24V Bombs (Aftermarket) - Diesel Bombers

 

Beef up trans, 150 injectors and a nice turbo.

 

you will also want to run some kind of high flow intake (air filter) and 4" exhaust to let that motor breathe.

 

I made 488 with 110hp injectors on a 62/71/14 and an edge juice with attitude and hot unlock. I never ran 150's. But with 200's I made 532 and it was too much fuel for the turbo. It got hot if not careful... well only when towing. top of the track was 1350 not bad really. good for 12.72

 

I'm about to go with 150's, a 64/71/12, headstuds, and my comp box, and I should be somewhere around 530, from what I've heard.

 

If your running a 5spd id probably go with a 13 or 14cm exhaust housing.

 

its an auto and i am going to have it built but i am gonna have a core sent off and buuilt and run mine till it goes but do you think with my hx40 and i can add some injectors i can hit around that number i found a good deal on a brand new hx50 and a 51 brand name for 500 from a young guy here he bought em and was gonna put em on a honda as twins and well it did not work out so they are nice i like em what you guy think keep my 40 or go with a 50 or what
