I'm lookin into putting a airdog 150 setup, a industrial injection vp44, and a set of injectors on my 2001 cummins. im lookin into the 90 hp-200hp range on the injectors. How big can i go on the injectors before i need to change my turbo?

 

I would say if you tow a lot or heavy don't go over the 90hp. But on the other hand if you don't tow at all and don't mind some hot egt's go for the 200hp sticks. You can always drive a truck with bigger sticks as a daily driver but you won't be able to use those sticks to their full potential until you get a larger turbo. Do you have a pyro?

 

So very true...

Before you do anything make sure you have gauge installed... (Boost, Pyro, Fuel pressure at least!)

 

towing heavy loads i would be cautious of the trans temp as well

 

i'm runnin the nv4500 5 speed trans. pyro, boost, and fuel pressure guages are goin on with the new fuel system. im just worried how much it'll hurt my power, performance, and mileage.

 

Power will go up for sure. (Lots of black smoke) But you MPG's will fall some for sure.

Typically the RV275 and 75 HP injectors are good for MPG's...

 

my 6 inch stacks love to smoke. long as i can keep the mileage up around 15 i'll be alright with it. i'm gettin 20-21 now

 

i have 150 hp sticks with a stock turbo. if i floor it the egt's will go to 1350 in no time and it defuels, and thats on level 1 on the juice/attitude but when i was towing the cattle trailer with the od off it only went to 800 maybe this will help
