Im putting my 850 seconds in my primary slot. What should I go with for the secondary though? I have a PFC w/ Commander but I dnot have a data logit.. so should i go for 1600's and get a datalogit (or borrow) or just get 1200/1300's? Anyone have some sell..

 

haha.. im just going with 850x4.. with a walbro fuel pump =]



should this work for 14lbs on pump and 16-17.5psi on race?

1680's for secondary and then just keep the 850's for the primary!

 

what exactly are your mods?

 

850/1200 should be more than enough for what I am guessing is non-seq twins. 850/850 is not going to be enough for 14psi and up.

 

what about just the 550pri and some 1680 sec. ones? i just ordered a rail....wiating for the bonus in 2 weeks for the injectors.....

 

Yeah 550 with 1200 and up is plenty. I ran 550/1200 on my old apexi single turbo running 18psi keeping the duty cycle below 90%. 550/1600 is the same as 850/1200.

 

wont the PFC whack out though? with the 1600's in? or am I on crack..

 

I think theres a way around it, but you'd need to ask in the ecu section probably for better details.

 

well isn't it better to run a smaller one up front, for tuning sake.....i mean, wouldn't you have to tune more with the larger injectors up front, rather than bulking up the secondaries....??
