I just picked up a set of ID1700's mainley for e85 but noticed this on their site:

"The ID1700 will deliver flawless stoichiometric idle and cruise mixtures on E85, but like the ID2000, should not be expected to do so on gasoline.

If you need flawless drivability on gasoline, the ID1300 will provide this, and is capable of approximately 150hp per injector on E85."

If occasional 91 is used how bad will the id1700's idle?

 

ID1700 is right on the edge of idling like a factory car. I've seen GTRs idling on pump gas with 1700s and I wasn't sitting there thinking anything about the idle.

I will have 1700s in my new setup as secondaries, using the 1300s as primaries.

 

Bump for a great thread, this should be a sticky. I'm probably making the switch this summer and there is a lot of info in here that will save me time and money. Thanks to everyone involved.

 

Thanks NBoost. I hope that this thread help our platform with this E85 decision. It really is an easy "somewhat" move but, there is always a compromise.


With colder weather and 5W50 oil (ID1000cc), cold starts are a (*****) or a (female dog!) It really only takes two tries but, I didn't have this with my stock gas setup running the same oil grade.

 

Mitch@Cobb added fuel for my cold starts, really improved things, but sure when running thicker oil and E85 during Swedish winter, it is a good idea to let the car idle until temps come back to something more normal before driving. I think any turbo'd engine deserves to reach 60-70C before asking turbo's to do their work...

 

Are there any particular challenges to running E85 at elevation? I assume you're at least at 5k. I live at 7k. While I don't drive my car much in the winter I will be putting a space heater in my garage next year to bring it up to at least 60* or so before starting it on days when weather permits driving it.

 

There won't be any challenges running E85 at elevation.

Cooler temps are one thing for sure, while running E85. Elevation only adds to it.


One disadvantage with an E85 setup (injectors, tune,) would be a revert if you decided to sell your car. You wouldn't be able to revert your setup very easily.


Not putting my car up for sale but, I did the injector install while the engine was out, this was easy. Now, It might be more difficult.

 

I realize this is a 2+ YO thread, but there is really great info in here.

I have AP, EP1 and upgraded intercoolers (stage 2) currently, and believe all I need to go stage 3/E85 is 1000cc injectors (ID1050X). Do I need any harnesses/adapters for these? Or do I/should I consider hardwiring?

 

If you get them through Cobb then they come with the adapters.

Also...just go 1300cc. You will love yourself for it in the future.

 

I was just going to say the samething. Do at least 1300 , as on upgraded VGT with a aggressive tune you will still have some headroom for safety. You do not want to either leave power in the table or pull down the motor twice.

Either way Sam knows his stuff so you will be in good hands.

 

Thanks for the tip. I will look into the Cobb injectors. Looks like they don't do 1000cc.

I say this now, but I'm not looking at changing out my turbos. I do agree however that if I'm going to go through the trouble of installing the injectors, I should just do it once.

 

Agree with the 1300cc. I would get them from Cobb and speak to them about your mapping needs. They probably have a map to meet your needs.

If you road track the car at a club event, I would recommend running a Stage 1 map.

 

That's a good tip. Never thought about that, but it makes a lot of sense. Essentially de-tune the car even though it has larger injectors/power potential.

 

What oil is everyone using in their E85 car?
