Assuming you have the proper tune, fuel system, solenoids and 42lb injectors how much can you spray on a dry shot? This is on my car all mods are in sig and I have been spraying a 125 shot.

42 lb injectors are good to about 650 Flywheel Horsepower...
your stock pump will start to give up the ghost around 450-550 flywheel horsepower..

figure where you are at now.... do the math...
by what I can guess from your mods...
you are close to max with a 125 now as it sits...and I'd be very surprised if your stock fuel pump can keep up very well as it is, let alone do more.

a good racetronix fuel pump kit will put you at about 550 RWHP before it cant keep up

is it possible put a external high flow fuel pump?

I already have a full racetronix fuel system Hell the stock pump went 10.4's @ 132mph for about 3 years, I went ahead and upgraded it last year before my luck ran out and the grim reaper set in!! I am just debating a 200 shot on the dry system.

i'm running this type dry kit on my 6.0 lq4 with the second solenoid converted into a two stage. running 200 shot. i've also ran this set up on several different lt1 cars with no problems.

There are several LS cars at my local drag strip that run dry shots are spraying 200 shots and more. Also if I am wrong please correct me but on dry shots isn't it the injectors that need upgraded and not the pump.

doesnt matter how big your injectors are if your pump cant keep up...

and yes.. you need both

That was my original kit also that has been upgraded with cheater solenoids!! I will make sure my tune is good and hit it with a 200 - 225 shot and hope for the best!

the nozzle will only flow 150. i drilled mine while leaving the tip untouched. you could also split it up and run 2 nozzles. i ran a tee (used from a purge kit) between the main line and the nos fuel psi reg. used the first solenoid for the 2nd kit and the 2nd solenoid for w.o.t.(first stage) doing that, it might be kinda fat on the w.o.t. stage, but, better than being lean initially. fuel psi is spiked when 2nd solenoid (w.o.t./first stage) is activated.

I run a dry kit, nos5177. H/C M6 with a 125shot with 42lb injectors, casper voltage blaster and a racetronics pump kit. 565rwhp/585rwtq SAE, the injectors were at 78% duty cycle.

I ran a racetronix kit, hotwire, and voltage blaster with 42 lb injectors and made 700-725 rwhp for 2.5 years. Most reliable setup I ever ran.

I have seen others run 60 lb injectors with the same setup to 800 rwhp.

Both dual stage dry kits.
