ok i was curious which one is better for horse power. ive seen alot of trucks runnin on marines and make 300-400 hp but not many with 75er's

 

They work for me! as long as you have a HX40/16 turbo, ATS maniflod custom plate, pump turned up!

 

I like my 75's, they should be able to make 500hp with proper tuning.

 

ok, that helps alot cause i am shooting for around 500 HP.
Brendan, how do you like your .024DV's compared to something like stock and 191's?
marines-1
DDP-1

 

If you go with the F1 370's, 500 HP would be an easy goal. DDP75's would be a tough push.. I have not made over 500 with DDP3's (90 hp).

 

I wouldnt do either. DDP is just a expensive marine injector with higher pop pressure. I would go FTE, Coal Train, or New Era. Much cheaper injectors then DDP with the correct spray angle.

 

I like mine, and yes 500 is a stretch but it is possible. If you are shooting for 500 I would go for a bigger unit from the start. As far as my delivery valves, I have no complaints. never ran anything other than stock though.

 

from the getgo i was told not to get 370's because they get hot really fast.... so where can i find injectors from coal train? i saw a thread that said they were officially taking orders but thats all ive seen
