Thanks guys, I am scared of that pump now, I called elite about how soon I could get the tow power atmospheric and info on the bag of parts, waiting on them to return the call.
Do yall really think the stock pump will be ok?

Live tuning would be a good thing to add to the build and maybe a cam...

What are you doing for the trans?

I talked with suncoast a lil while back about one but still thinking about it. I figure I can do that anytime.

I say f industrial and their pumps. I will dump mine before it blows and they don't accept any responsibility.

60 HP nozzles or 60% over nozzles?

60 over, Is what it says on the site, I was thinking its the same but have read otherwise now.The guys at Rudys seem to think it will work fine. I talked to several people today half said it will half said it won't maintain rail pressure. Several people say its in the tune, idk but I don't want the II pump if its has issues and think dual fuelers are way over kill for what I need.

60% over and the stock pump will not maintain rp on big tunes. Go 30% over with stock pump.

I talked to Mike at KEM and he said if it doesnt hold pressure he could fix it, he said some will some wont. I don't know has anyone tried it?

I wonder if he's going to lower pulsewidth to maintain rail pressure?

Probably

Ya. I tried 2.2ms of pulse width with stock pump and 30% over nozzles with ported rails. Rp was 23,400psi which is low by a little bit. 1.9ms pulse width was fine. 60% over nozzles will be worse. Sure you could cut the pulse width back but what's the point of the bigger nozzles then.

I'm lost on all that, all I can go by is what he told me. I called Mike after I called Rudys back to change them to 30% nozzles but they had already shipped the 60% ones. Will I be loosing anything if he has to turn the p/w down vs going with the 30% ones?

In all reality you should make more power with a bigger nozzle and less pw anyway so you should be fine

It will be injecting fuel for less time but it will inject more fuel during that time. It'll prob be about the same or at least close.

78f100 · Mar 13, 2012

thanks guys, I'm sure I will have alot more questions to come, but I'm learning!

WoodBoy · Mar 13, 2012

All in all you should have a better running truck with the 60s over. Like stated you will need a shorter PW tune, but like Shane stated you will be injecting more fuel for a shorter amount of time. The fuel will also be atomized better. Only downfall is all your tunes will more than likely need custom tuning in order to maintain FRP.
