Wow.


Any chance he may also need a pump?

 

I did have to eventually get rid of my stock in tank and go with a 255 in tank. I already had the inline 255. Being that he is a returnless system, upping the fuel system is in his future I guess, but larger injectors should come first.

 

First thanks for the help and info guys...I have the LS6 cam.

The night of this run it was colder than a well diggers *** in the klondike, so I am sure the boost jumped up to 8# or so, problem was I had to get up on the wheel for a sec when it started creeping a little slideways after the tires broke loose, so I can't say for where the boost was then.

I do have the 255 in tank, but may have to move up?

For injector tuning issues I will just head back over and throw it on the rollers to have it tuned. I think that would prolly be the best...agree? With that what would be the safest route?

Again thanks to all of you.

 

Fuel supply (pump) was the first thing I thought of also. I know I only have a little 5.3, but my cam is bigger(I think), and my AFR is 11.2, and I never see IDC that high EVER. I don't think the injectors are the problem.

 

I'd upgrade injectors first as Dew said but you may want to also go ahead and put it on some rollers and check the Fuel Pressure under boost.

 

I have been running the 60lb'ers for almost 2 years now with no problems. I have yet to put the turbo on so my Injector Duty Cycle(IDC) only goes as high as 33% so I know I have plenty of room to grow.

As for tuning goes all I did was change the Injector Flow Rate(IFR) and that was it, no other changes. These injectors have the same basic characteristics as the stock units.

 

i have heard many people swear by the boost a pumps...i was just wondering if installing a boost a pump would help??

 

Thanks. I haven't put it on a dyno but I do goto the track alot.

I use the 60lb Siemens with the factory plug ends (no adapters needed), KB boost a pump, and Lingenfelter intank fuel pump.

 

as long as fuel pressure isn't dropping, you need to step up injectors. (the boost a pump will work but will incorporate another item that can fail. and plenty of people I know can confirm it DOES happen)

Even if you do have a clogged fuel filter(super rare) or bad pump, I still say that 6.0L and 2.8" pulley needs bigger than 42# injectors. Comparing a 5.3 to 6.0 on IDC is not fair, even with cam values. Hell the 5.3 can produce ~11#'s of boost with the 2.8" but the 6.0 can only produce ~8#'s. Just an example of the volume difference.

SRT what's the flow on those plug and play 60's at 60#'s? Just like the mototrons? You should link that thread discussion in your sig. LOL

 

What 60# injectors are plug and play for the maggie?
