looking into a fuel only build

[dommel01]

No lol.

I would try a good low pressure system and 60s and see what it does before you.replace the pump

Whats considered a good low pressure system?

Airdog and Elite Airdog upgrade kit.

I've got a II pump if anybody wants one. I can flow it to make sure it's running right if need be.

Airdog and Elite Airdog upgrade kit.

weve tested this on two trucks same build with our 30% nozzles..one truck had airdog and upgrade other had just airdog and both trucks held same rail pressure

 

[blk350on20s]

Are they they holding rail pressure craig? Im seriously contemplating a set of 30%

Only on extreme street but made 630hp with batmos

do you think there is a certain % nozzles you can go before needing the upgrade kit or?

 

[Craig@MFI]

if your upgrading pumps i would just doesnt seem needed on just nozzle swap

xrace isnt holding RP then?

Fyi my 110k mile pump won't hold rp with 60hp elite nozzles and kem 345 1.92 pw. I have tried every regulator adjustment possible with no luck. I havent decided if I should just go back with a new stock pump, II, or duals. I'm scared of the II from what I have read but it just seems so much easyer.

I didnt want to be giving out bad info, mine does hold rp with stock rails back on. My ported ones were leaking, I have never ran more than 1.92 pw though.

What would the stg 2 ported rails do to the rail pressure?

 

[White_monster]

Stage 2 rails will prob surge worse than the stage 1 rails do with a stock pump. My stock pump, elite 60hp nozzles, stage 1 rails hold rp on x race just barely but if the filter clogs at all rp drops 1000psi

 

[dommel01]

By surge what do you mean?
How would the stg 2 rails perform with an ii pump and 110's

 

[White_monster]

The surge I refer to is a fluctuation in rp while cruising and it is very annoying. It makes the truck lurch while cruising. Stage 2 rails and 110's might work but in all honesty I think you will be fine on stage 1 rails till you move into the 200hp nozzles and up which the II pump can't keep up with.

I hear ya there. I think the main benefit on a stock pump of adding the airdog upgrade if you already have the ADII is extending the life of the pump by not allowing it to go to vacuum. The factory regulator in the upper fuel filter bowl is set at @2.5 psi, and with the banjo fittings after the bowl... well, you see what I'm getting at. I'd strongly recommend doing the airdog upgrade if anyone's running more than a stock pump.

For what it's worth, for 99% of ths stock injection pumps out there, on the most radical tunes, even 60 hp (15%) nozzles are too much to maintain. On a recent build with stock injection pump, airdog II, airdog upgrade, stage II ported rails, and 60 hp nozzles the truck would barely maintain on the spartan 300 tune, but would be about 1500 psi below demand on the 310. these results seem typical of what I've seen, so if you're running larger than stock nozzles on a stock injection pump, and maintaining you're one of the lucky ones.

Shane earlier referred to a potential surging problem with stage II ported rails, and we have yet to find a customer with an issue with the rails. They work just fine. No power gains have been documented yet with the stage II rails over the stage 1's, but the theory is having a larger rail capacity stabilizing the pressure especially on hard runs.

So when are yous comming back out with a stock mod style pump?

Charles clean out your inbox i cant reply to you its full

Don't hold your breath. it's gonna be months. We're spending most of our resources on some other stuff I can't mention, so it's on the back burner for now.
