Have i reached the end of stock injectors with only a catback, boost and intake?!



I hit 265-270 load peak and tapering down to 230 at 7k

 

Your stock injectors are fine for your stock turbo.

 

You're fine. I ran my stockers out to 127% IDC. I've seen others start to max out at 119%. Slap in a walbro and you'll have a little more headroom, if you really want it.

Do this at the same time as cams and you'll be in good shape!

 

Lean it out some as well and get some of the IDC back.

 

I have a set of Precision 680's for $150 shipped.

 

yeah stock injectors are almost running flat out on a boosted stock turbo.

either lean out a little, install a walbro or get bigger injectors..

 

Hmm.. Im already running 11.2 afr, I could bump it to 11.5 or so. I guess ill get a walbro 225 with my GSC S-1 as my next investment. Hah!

 

yeah lean it out to 11.5 ( take some timing out up top and then re-add it back in.. )

 

Thanks for the offer, thats a great deal on a set of injectors. But i plan to get some 1000's and switch to e-85 in march when i move to charleston,sc. Cant wait for that

 

I was running my stock injectors out to 119-120% IDC, get a Walbro pump and you'll have plenty of head room.

 

Its just weird, not saying that 120% wont work on our cars. But im a electrican and when i see something read 100% duty that means a constant signal to it. Meaning the injectors dont stop spraying. I guess the stock value of 513 for injector scaling is off a tad.

 

Stock injectors are 560cc, so yes, the scaling isn't exact.

 

The general consensus I get from exploring what % in evoscan means your injectors are really maxed out = 110%. I've heard this mention a few times by the more senior members of the ecuflash section of evom.

 

^+1

still injectors are meant to be run at less than 80% (dunno why, just what most MFC's state).

And anyways they are cheap as chips now... $350 for FIC1050's is a GREAT DEAL!

 

+1 on get the walbro pump. I had same issue and it solve my problem... for now.
