Ok guys, I have a fully built turbo gsr, I recently got tuned on q16 fuel. Yielding 750whp. But now I'm looking to make my car more street able, so my options are retune on 1000cc injectors and 91 pump gas, or e85 on 1000cc or the 1600cc on there now, let me add that this car I rarely driven but started at least twice a week. Will e85 be fine sitting in my tank as long as I start it on a every other day basis? Let me know what you guys think thanks in advance...

 

Here's the deal, if this is a street car you need to consider that just because there's an e85 station by your house doesn't mean a station down the street or even 30-40 miles away will have it. So if you have to fill up and can't find e85, you're basically screwed unless you keep a 5 gallon gas can in the trunk full of e85.

 

Well that's the deal, this car will be driven maybe once a week if that. To work and back so I mean if I see its a little low ill fill up I have another car as my daily. I'm more worried about the sitting time

 

As of now the 1600cc injectors drive like crap on the street, if I use e85 would would tht make them a little less rough o should I use the 1000's for sure?

 

What brand?
Injectors that large normally idle and part throttle/load like ****, that's the trade off of making power.. you could go with an 8 injector setup and have smaller primary injectors for the low load stuff, but that's a lot of work for an existing setup.

 

Ya true. There Bosch, they were injectors I had sitting around so I used them. But I know tuning on e85 you tune on the leaner side which would make the injectors a little better but not sure of how much

 

SMH and this is how people end up posting new threads crying cuz their baby got stolen

dude a 750whp fwd car should never see public roads. your gonna be losing to 300whp cars or even slower lol especialy froma dig. unless you can afford $400 for new drag radials every 1800 miles and even then your car gona look retarded and u just risk unwanted cop and thief attention

 

why would u take yor car to work?im pretty sure people know that your car makes 750whp and prob has lots of goodies underneath. DONT DO IT. KEEP it locked up safe

 

I'm going to tune it down. So I can drive it every "once in a while"

 

What the **** are you taking about. Plenty of people daily their cars regardless of the power they make, I have a friend who daily drives a 1000hp 8 second supra with a 5000 or something rediculous rpm stall converter and a powerglide.

I sometimes drive a 600rwhp c6 z06 that has brakes that cost more than your whole car....

What's the point in building a car if you aren't going to drive it. And he hasn't given any info on where he lives or works, or pictures of the car... by your logic you shouldn't drive your car either... and I have your tag number from the videos and pictures you post so if I wanted to I could find out where you sleep at night...

Stop being a tool

 

Lol. Ya that's the way I see it if I put all my $ into I wanna drive it

 

I just had my car tuned on E85. The tuner said the fuel should be good for about three months before water becomes a problem. Because the fuel system is in a closed loop, the fuel isn't exposed to air, which is why there is an issue with it going bad. I keep a 5 gallon gas can full just in case i don't want to drive 30 miles to the nearest station. Drive that shizz like you should and it won't be a problem.

 

Nice. Thanks man

 

 

If this is for a street tune then wantboost nailed the limiting factor. If E85 is not readily available then you will be range limited. But if you choose to run E85 then you will def want the 1600cc injectors. 1600s are too big to idle on gasoline.

 

Ya but as of now my driveability is garbage due to te 1600's will it be better on e85?

 

There on q16 as of now

 

Basically yes. E85 requires 35% more volume than gasoline which will keep your injector duty >0%.The driveability issue you are having is likely because you cant run the injector pulse low enough to lean out the AFR without the injectors shutting off. A common issue with large injectors.

 

Ty. I appreciate everyone's knowledge/opinions.

 

Yea larger injectors don't exactly have the nicest low pulse width operation, hence why when you see high power cars they normally have 8 injectors, 4 smaller primaries for idle, light load, etc and then once a certain rpm or pressure ratio is reached the bigger secondaries start firing

Like muck said, the e85 should make everything low in the rpm range better, as the injectors will
Need basically 33% more open time, so idle and part throttle driveability should work

And again, like I said and muck reinforced, you need to make sure that e85 is available around the places you mostly travel. I know a lot of the evo guys keep 5 gallons in the trunk in a jerry can just in case they get stuck somewhere without e85

Here's a station locator, it should be 100% accurate unless a station was recently built or stopped carrying e85. It just uses the government database of who has the proper gear/licensing to commercially sell e85

Oh and if you plan on storing e85 for a long time or keeping it in your tank, sta-bil makes an e85 stabilizer like their super awesome gas stabilizer. You can get it at most Walmarts and auto parts places

 

E85 is good stuff just requires more maintenance, more fuel system etc.

But if you have some big injectors they'll idle better on E85 due to the need for more fuel. I had to drive from Nebraska to Indy once and a nifty app on my phone got me E85 the whole way back. But it is the midwest after all...

 

If sitting for more than a month the injectors will need to be pickled so to speak with gas or wd40 (recommended by injector dynamics).
If you're worried about its hygroscopicity nature you could always install an ethanol content detector like the zeitronix unit
