CFM+ To do or not to do
 

So will this really help my truck!?!?! I am needing to know. A few ppl say no. A few ppl say yes. So what else can you tell me about it... I got the adrenaline and a 'few' gauges(fuel press thanks to LUKES!!), intake, fass, thats kinda stuff....

On the VP44 Cummins it is more for looks than function. If your going to upgrade get the ATS ArcFlow.

Well im looking for my next purchase.... guess its gonna have to be injectors... but OUCH! id rather not spend a grand for everything... thats labor included..

What size injectors you looking for Jay?

well i guess 100hp. but im just trying to make sure I have enough air to suppport everything. course Ill need a turbo later. But im hoping to get away with not having to get one at least for a little while...

I would probably get some RV275's then when you get a Turbo jump up to some 150's or even 200's.

Hey Luke, why do you prefer ATS? just curious.

Another thing: it's interesting how the CFM+, and ATS and AFE for that matter, can give pretty significant gains on CR trucks around the 1900 rpm range (Tri-Valley Diesel in NorCal did a few dyno runs with different manifolds) but not on VP44 trucks?

Can anyone say why that is?

Thanks, Mike.

yea I would like to know as well. Cuz I know a few guys who have VP trucks and are running the ATS one.

Personally, the CFM+ or other intake horn is not something I will do until I am completely out of modifications, the gains just aren't enough in general.

Its because the factory flows good already on the VP44 trucks.
