I was just browsing eBay for a used set of ID injectors, and I came across this listing.

New Bosch EV14 80lb 850cc Fuel Injector High Resistance USCAR Connector

Thoughts? The title has all the right key words but looks too good to be true.

 

 

Aww..so no?

 

It's not the worst "new idea" I guess.
IMO not worth the hassle or the risk, but I guess if you're willing to pinch every single last penny....

 

After further investigation, I came across your post to refer to sturovo's thread on EV14s.

I came across this during my search:

You're right. The risk isn't worth the hassle/risk. I will be sticking with IDs.

 

for researching and cross-linking.

 

I think most of the regulars and I would basically agree that, for budget and/or smaller size fueling needs, FF is pretty much the go-to.
Or just go with ID and never look back.

One of the guys I'm tuning locally just recently learned the REALLY HARD and REALLY EXPENSIVE way that the two things you never wanna cheap out on is injectors and ecu

 

Out of curiosity, how do you know that those are redrilled?

 

Larger injectors that we all see are reworked (redrilled/new nozzle/etc.). The differences are the testing method and validation of new spray pattern.

I took a quick glance but I didn't see any that flowed at 850cc

 

it's like comparing a TSE manifold to a tacotaco: both might "work", but the quality/design/engineering/etc could not possibly be any more different

 

All pump gas applications: FF640s
E85 up to 425whp: ID1050x
E85 up to "lol" whp: ID1300x

 

we ran outa fuel on colipto's FF's on only 20psi* on pump

*but he may very well have some sort of issue with his setup.

 

We had FFs on a 2860 car yesterday showing tons of headroom in duty cycle at 240kpa.

 

I really don't think this was the case.

Bytevenom suggested that the OEM FPR may be restricting the increased flow pressure. Could there be any truth to that? I honestly doubt he's maxing them out at the HP that he's running.

 

plenty of guys running oem fpr to well over 300
I agree that it's most likely a problem with something on his car, maybe clogged something or pump is faulty. I dunno. all I know is we maxed them out lol

 

If I recall correctly from my tuner, I was around 80%(mid-high) duty cycle with E85 on a 2560r at 15psi, and this is with FF610s @ 4bar.

 

The FPR is after the injectors, so it can't restrict flow to the injectors.

 

Ah okay. Thanks for learning me.

That said, what's going on in his log is kinda perplexing...

Stock pump?

​​​​​​​He's running 93 and an aftermarket pump. Should have way more headroom than you left, ya know?

 

FF640s should be capable of 300whp without any trouble at >43psi DFP. If you experience otherwise, your car is broken

 

DW200, I could be recalling incorrectly. Its been some time since I got it tuned.
