I am looking for opinions based on experience with building up a P-pumped 24. I have a 2004 F250 4x4 with a 12 Valve and an NV4500. I have several motors, trucks, and parts and had some ideas. I have done several Cummins/Ford swaps and now it is time to build myself a nice pulling/quick off the line weekend driver. I was thinking about a 24 V with a P-pump and twins. My question is, what should I use for injectors, size turbos, delivery valves, things of that nature? I have experience with these and have my own ideas, I just wanted to hear some others. Thanks in advance.

 

just do a 12v as you will make more power with it. thats imho.

 

I currently have a 12 valve in it. I am building a 24. Trying to see what combo of injectors, DV's, turbos, cams, etc, have worked best for those who have already done it.

 

Go with an hx35 and s400 twin setup, got it only truck and its great, spools up real quick

i would keep it a 24 valve and do some porting. do a 13mm pump

 

Finally, someone that has done it! I have a 12mm pump. How much difference is a 13 going to make? Currently in the pump there is a #0 plate and AFC mods. I have thought about DV's and different injectors. Did you have to change the injectors in any way? I have read that you have to change the pop-off pressure to 240 bar. Any ideas?

 

the bigger pumps flow more at a lower pressure so you will have to drop the pop off pressure to compesate or youll end up with a chug mine did cause the pop was too high. and a 13 will make a bit of a difference on power, but if your not going to build a monster i would stick with the 12. i would go with a set of II tow twins or a bd R700 kit for fast spool and good towing. II also has a good setup on billet DVs also. also what size injectors do you currently have.
