yes you have a point there.but stock srt-4 injector are 520cc right?
I am gonna run the setup first on my stock block to see how everything runs
in the mean whyle i can build the 2de engine...

[filipinop1405]

well i'm not sure what the cc's are for the srt-4 injectors but what are you're power goals?

[DaRk_MauL]

Ill be happy with a steady 300hp

[speedfoos]

SRT-4 injectors are 577cc Ching.

Check this page out. It's a good way to calculate injector size. If you're shooting for 300whp, the 577cc injectors will run at about 85% duty cycle which is just fine.

thx clint good nfo check it out and yes the srt 4 ones wil be at 85% so they will
be fine for my project...

put my kw V2 suspension on this weekend. What a difference in driving behavior.Still have some adjusting to do because its to hard in the front right
no and going bumpy on the road, cornering is great tough!

[filipinop1405]

thanks for clearing that up for me clint.

nice coilovers ching

[exturbo6]

looks good man. good luck with the build!

[emjay]

ok .. about the srt-4 injectors ... 85% with a return setup or without ???

mine are at ~50% duty and im only at 196whp ... returnless. You guys sure it will be enough??

Aren't there two srt-4 injectors as well ... ummm 540 sumting cc and 577cc ??

I am going to go for 300 whp as well .. and i was going to upgrade my injectors to 750cc RC engineering and it costs 400 bucks !! FUCK and i would love to not get this .. but last thing i want is short on fuel come tuning

[DaRk_MauL]

hey wel if i use the site that clint posted
and i take your values at 50% duty it get
that you need 643cc injectors. So i found this sheat that also is refering to feul press.
I think its returnless but not sure about that.

Found also that there are 3 stage of srt
injectors.
Stage 0 = 527cc's
Stage 1 = 577cc’s
Stage 2 = 682cc’s

[filipinop1405]

jay i would go with a return line...it may be cheaper than just going bigger injectors if not that... i'm sure it'll be safer to go with the return lines! just something to look at and think about.

[DaRk_MauL]

yes that true

[speedfoos]

The return line is good so that you have positive control of the fuel pressure using an aftermarket fuel pressure regulator with a 1:1 boost reference port. In otherwords, for every extra 1 psi of boost it sees, it raises the fuel pressure by 1 psi. That's the only (although very important) benefit to going to a return system. If the stock fuel pressure regulator was adjustable then there would not be a need to change it.

[filipinop1405]

oh shut up clint...my shyt sounded better! damn always gotta put down the enlisted guys... just fucking with you... wonder if bob still has his stock one with boost reference...hmmm i'll check, thanks for setting me on the right track.
