Well I havent even got my injectors back from F1 yet but I know that I will be wantin to get dual cp3s pretty soon to take full advantage of my new injectors and try the new tnt R. I may have a stage 2 from floor it lined up to get me by until I can afford duals but wich one should I be shoping for?

Duramax or Cummins?
Why?

TIA

 

I have run both pumps in my Evil Twin setup, no difference whatsoever in performance. Run the pump you can get the better deal on.


My current setup with a Cummins pump


My previous setup with the D-max pump

 

Why did you swap out the pumps?

 

He was the test fitter to make sure the cummins pump could be used with our kit

 

I heard the Dmax pumps are easier to fit on the top of a dual setup and that they flow a little more when comparing stocker to stocker. Is this true?

 

I understand the same thing and that is why Brady uses Duramax cp3 pumps in his upgrades at II...

But that is only my understanding and I can be very wrong about that.

 

Thanks Lloyd, I am lookin for my second pump right now for later.

The reason I asked is because I THOUGHT the dmax pumps didnt like pressure very much, and to see if any of yall liked one over the other.

I supose I will just get the one I can find the cheapest. As long as the dmax pump will flow the same or more and it is as reliable thats good enough for me. But if it is easer to install thats a plus.

Thanks for the info fellas

 

Might help determining which pump to get based on if there is a price diff in the evil twin set up.Is one kit cheaper than the other Lloyd?

 

I am not trying to answer for Lloyd but I think the only diff is one line, that is bent differantly.

 

go with the chevy pump lly type preferably

 

No difference in price. And I didn't forget about you.

 

Why is that?

 

D-max pumps are cheaper.

 

if you get a PPE dual fueler, go with a dmax pump, and save yourself some aggrivation! they dont make lines for the cummins pump with that kit.

 

its the same as the LB7 pump..

lbz/lmm pumps are different [better]
