is the fuel system that comes with the drag kit for an LS good enough to see 9 or 10 psi? (if tuned) on B series injectors.

no.

and how do you "tune" the drag fuel system? heh

 

hmm.. good point laff. well, tune hte s-afc hack ?

what would you recommend for a drag setup to be run at 9 or 10 psi... that doesn't come with the kit

sam

 

s-afc hack + dsm injectors will do it....

but the FMU won't ..

 

cool. i was considering the drag kit, but i'd love to do a custom kit. I'm just concerned about not having all the fittings, hoses, etc... all those little things.

your thoughts?

 

if you don't have much first hand turbo experience, get a kit

 

fair enough. i've done hte na route with jun3s, and 12:1, its turbo time, never had one though.. sounds like a kit is a better option for me.

I disagree. I've tested the DRAG fuel system up to 11psi on a stock LS.

 

heheh, ben we all know what fuel pressure looks like @ 11psi on the drag fuel system... although the pump never actually gets to the pressure it should.. which ensures a timley death for the pump and an eventually broken motor

 

Actually the pump held up pretty well and the A/F ratio was still a little on the rich side. I agree that the fuel pressures at 11psi are astronomical but the question was whether the DRAG fuel system would be able to support 9-10psi. From my experience, it has been able to.

 

Reliably? hehe ... it's your motor
