these got ran successfully to 775 rear wheel & 840 tq today at a fuel pressure of 76psi. these will work just fine with the stock computer (high impedance)

also in my fuel system:

speed inc billet rails and BIG filter
cas rising rate regulator
twin in tank walbro gss340 pumps
russel-8 single feed line
stock pressure line used as the return

i was absolutely SURE i'd have to move to 83's etc. but fwiw these babies are about maxed but talk about impressive! im glad i got my set when they were 430 a set.

dyno graphs in homepage link.

 

awesome power!!! congrats!

 

Were these easy to tune, I'm pretty sure these will support the goals I'm looking for, now the ? is......

These or the 57# Siemens, the Siemens have the benefit of being flow matched.......

I got a 420LPH pump, CAS regulator, Speed Inc. rails, etc, all braided lines......its ready to go on that side......

 

i dunno how far those seimans have gone before?

i really dont notice mine not being flow matched

if you are looking under 800 i am pretty sure too.

they were easy as pie to set up with edit on my car (before the switch to dfi).. i posted my flowrate and fuel pressure here before for my tune w/ stock offset
and i didnt hear anything at all about difficulty with dfi, i dont imagine there was any at all.

 

Can you post the flowrate again.........

I Pmed you, but I guess we are better off talking in this thread to get more info out.....

Where can I buy these?

I got your PM, thanks for the help......

 

good luck with your combo dude.

 

David whats your inector duty cycle if you say their about maxed?

 

something like 80% at the fuel pressure i'm running.. so they can do more, but 80% is the rule of thumb for most you want to run the injector.. which lots of people go over without problem.

 

These seem to be the ticket......
