I know the info was around at some point... but I cannot find it. been searching for a half hour. maybe my searching skills are lacking lately.

Trying to get my car setup for the summer; and all of the 1000 miles it will probably be driven. having the injectors gone through, but might just say screw it and buy new ones if I can find out what the heck they are.


I know they are rated at 880cc @ 5 bar, but what are they in the real world?
Anybody have a link?

 

Probably testing/cleaning is the way to go?

If you want to upgrade, I will have ID 2000 cc injectors available for a very good price (ran only 3k miles) and switching to ID 1300c c (which is what I wanted but weren't available last winter).

 

I have them at a local shop to be gone through. I am not changing injector sizes. Too much hassle to get any tuning done with the HKS.


Just want to figure out if I can get a replacement if it comes to it

 

injector flow is part of a proper inspection. You should get all the info from teh shop that has them. If not, dont pay them a dime. 725cc will prolly be close.

 

Got them back. the test out good:

 

so roughly 650cc at 3bar, 780cc at 3.5bar?

 

They flowed ~650 @ 3 bar per the report I received.. not sure how they scale other than that APS rates them at 880 @ 4 bar

 

thats just too small. A single walbro 255 pushing through proper plumbing will keep up with a set of 650cc injectors no problem. Why even bother with the second pump in that kit!?

 

Not sure what to tell ya.. it does run at a one bar higher fuel pressure... other than that, you are more versed in these things than I am. Just posting up what I found out.

 

it just depends on what you expet whp wise. under 600whp dynojet on pump/race gas and they would be at their limits.

 

as an update, I am moving on from the APS supplied injectors for this season. I have a set of ID 1050X injectors on order. these are a new to market injector over the last couple months (from what I am told)
