How far will 780cc injectors take me?
What types of turbo's will the PTE 780cc injectors work well with? I just want to know if these injectors will work with turbo's like the 50trim or 3076? I realize they'll be fine the Evo green which is also a possibility for me, I just don't want my injectors to hold me back if I install them now and get scaled and what not.
Any suggestions?

I'm going to run 850's on my stock turbo car (stockers are at 95% on current mods) - figure i will have enough injector for whatever i want to do in the future?
If your questioning 780's then just jump to 850's or 1000's and don't worry about it

on 93 octane these were the results from my own car:
20g evogreen @ 26psi DLL 400awhp - 680's were fine
35R @ 28psi DLL 504awhp - 780's were at 120% IDC, AFR was 11.5 until 7000RPM where they moved towards the 12's regardless of how much fuel I threw at it in the fuel map.
35R @ 30psi DLL 534awhp - 880's are fine at 96% IDC with kenne bell boost a pump.

EVOm is no different than any other forum...there's some old hands that said this and that a long time ago and it's been regurgitated through the ages. Sometimes you have to ignore the gospel and figure out what works on your own.
Just like when I was told you can't go beyond 680cc injectors on the stock ECU by a reputable tuner on this forum less than a year ago

the IDC calculation isn't accurate....naturally you can't physically flow more that 100% IDC, that would mean the injectors at static and spraying all the time. Notice I mentioned earlier that I didn't begin to lean out until 120% IDC ![Thumbs Up](https://www.evolutionm.net/forums/images/smilies/smilie_thumbsup.gif)

I don't like pushing the duty cycles because when you do long hard pulls you really stress the coil to heat up and failures can occur. I try to stay under 80% but typically run up to 90% as I make more power than I intend. I've had friends run years on stock injectors saturated going down the track with no failures. I've also raced a turbo honda that lost a motor pushing the injectors pretty hard and he lost it after only a week.
I've been saying since the Ecuflash forum started a lot of ****. In the end it all turns out to be true. One of them is you can run any size injector just as well as a standalone and usually better than an AEM. I run 1000's on a cammed DSM with enough base fuel pressure that they look like 1200's to the ecu. It'll start and idle fine in freezing weather with a mini battery every time.
So yeah, experience says don't push injectors. Its your engine or your customers so I personally don't care, just saying.
You can easily run 1000+cc injectors on the stock ecu. I actually think 1600's would be fine.
