so racetronix if I wanted to do max 550rwhp you recommend Racetronix PnP harness with a pump booster? that would work on either a 5.3L silverado or 5.3L tahoe?

if so where can i get it?

this is being a plug and play situation with no ***** or switches, you install, set and forget type of thing?

thanx

 

and that Racetronix PnP harness with a pump booster is with only a stock pump for 550RWHP.

 

Both Parish and I have the dual intanks which require you send in the pump sending unit to racetronics to have them modify it
Racetronixs doesn't have a drop in pump for the truck intanks

The harness plugs into your factory stuff and powers the 2 intank pumps

the stock pump is outta it's league at 550rwhp
you would need to upgrade to a custom intank walboro

Pm me if you have any question

 

you see, a stock pump can do 550 rwhp with a booster, I have heard people have supported 700rwhp on ls1s with a racetronix HW kit.

i wanted to know that for sure would 550RWHP be supported with a stock fuel pump w/ Racetronix PnP harness with a pump booster plug and play set and forget idea...racetronix are fuel gods when it comes down to it.

dual race pumps are loud very loud. not interested in that.

thanx though.

 

actaully the pumps aren't that loud as one of them is setup on a hobbs presure switch
so one is running the intank walboro 340 is maybe a tad louder than stock and quiter than a stock pump and inline setup
Imho how long is the pump going to live working that much harder
For what it's worth you can't skimp on the fueling pumps injectors

For sure racetronics are Damn Good at what they do
I've been to there shop in person and met the man behind it all

 

that hobbs pressure switch...its a switch that is set so that when a certain boost level is reached the 2nd pump kicks in?

if you upgrade with a booster and new fuel injectors like 43lb's you should be fine i believe at 550rwhp.

 

We do not have a single harness for the GM CK applications as an off-the-shelf item yet as we were putting the production off until the entire pump kits became available. We could quite easily make some up in a matter of days. The harnesses could be used in conjunction with a MSD pump booster which would allow the factory pump to support 550RWHP. This would keep everything fully PnP without the need to drop the tank.

Thunder Racing has our F99 harnesses in stock now so perhaps they would be willing to carry the CK versions as well?

PS. the posts with people supporting apx 700RWHP using a RX harness & booster also were using prototype in-tank pump assemblies or F98 versions.

 

so racetronix can you put a few together, cause I want to buy a few. PM me

 

also that msd pump booster, will work for our trucks...i remember something about our trucks are returnless fuel systems?? im not sure.

 

We do not use forum mail or messengers.
Please direct all correspondence to sales@racetronix.com


We will contact Thunder Racing to see if they wish to carry them at this time.
