I am a turbo freak :P
I am currently running a stock gsr with a turbo setup on 10 psi on pump gas and was thinking of swtiching over to E85 and am just wondering how much more boost can I run safely with E85?
stock turbo gsr vs e85

You would need to get re-tuned to run on a different fuel. Your tuner will be able to safely judge what changes need to be made for the most power. I dont think you should exceed what you are at now on stock internals. You are pushing the limit of your motor if you go for anymore.

Its not a matter of boost, actually E85 has a higher resisitance to things like knock and lowers cyl temps. So really you could actually got for more boost. But honestly id stick with the same boost level, 10psi on pump and 10psi on e85 are two different beasts.
Your issue is fuel. You will need a retune and a fuel system that can support at LEAST 33% more fuel then your running now.
But once you switch you will love it, its a great fuel for an engine, especially a boosted engine. I should know, I run it.....
If you have any questions feel free to ask and i'll try to help you out.

The only things that really need to be changes at the injectors and fuel pump.well im running 750 RC injectors with a aem fuel rail for my fuel system what about changing all the fuel lines over ?

Most of the lines are metal now adays. And I know the teg is metal. So really the only rubber you have is a sort length at the fuel pump and from the metal lines to the rail. And the lines today are ment to take about 20% ethanol. So running E85 there is still 15% normal fuel to lubricate the pump/injectors/lines, so really it should be fine for a long while.well im running 750 RC injectors with a aem fuel rail for my fuel system what about changing all the fuel lines over ?
750 should be plenty to get the job done then, so long as your not using a big snail. I know on mine im runing 750's on a tiny 13T and have about 20% headroom on my 750's. And thats with the turbo MAXED, like 25psi maxed.

Totally missed that avatar pic. Well you can always tune and just stop when you reach the limit of the injectors. But I dont think 750's will cut it to get the full potential out of your set-up. But even if you do have to lower the boost you will still be making more on less boost with E85.yea im running a big 60 trim snail haha

Octane is a very small part of the benefits of the fuel.

Hey Speedin, I am getting 1000cc bosch injectors, when i get my turbo what else do i need to run all e85? Its a fully built motor, i have regulators and walbro pump.Totally missed that avatar pic.

I know, I was just making it clear to all who look at the thread.im aware.
Its not really difficult to switch to ethanol. Really you just need add about 30-40% more fuel to your set-up. More headroom is always a good thing with injectors. And it sounds like you have the fueling system down.Hey Speedin, I am getting 1000cc bosch injectors, when i get my turbo what else do i need to run all e85?

If I had to really simplify it it would be this:
- 30-40% more fuel
- Tune
So so long as your not going with a gigantic turbo I think 1000's should be fine.

Ok cool so as long as i have those 1000's i should be fine. I am going to be running a Garrett T3/T61 .63 trimI know, I was just making it clear to all who look at the thread.
