Does anybody actually run E85?

[Magpie]

MattR point on the storage. I can use smaller drums as needed. Race E85 is available without too much drama, plus I would not be running it all the time, special occasions

Beavis yes you could however you will still need to have the car tuned on a dyno.

angusis2fast4u - yes GT AUTO does my tune through Automotive Plus.

sailaholic is correct I will have it tuned on a race fuel E85. There is too much risk of bad quality fuel and I will not risk the engine. The sensor should adjust for a bad batch of E85 out of the bowser, but it will only make adjustments based on the initial E85 tune and the 98 tune.

I will only use E85 on the track so I will buy it in 205ltr drums, that should be enough for a track day.

Magpie - How much of road driving does your car see? I ask because isn't Race E85 up somewhere at at $2.19 per/L? Like i understand the insurance bit of it but United E85 has been proven to be exceptionally good in thousands of street cars and race cars in Australia who use it daily so unless your car is purely track only (as in you don't ever take it out for the occasional drive) why would you want to spend that bit extra? I would just have thought you would run United E85 so you can run it always and 98 only when you can't get E85. I know you said you were expecting only 10hp more, but isn't the magic of E85 all in the bottom end power? I would think the car would be extremely lazy compared to running E85?

angusis2fast4u my car is lucky to see 150km a month on the public roads, even less with me working away.

I'm going to leave the brand of fuel decision in the hands of the tuner. However as you have observed I will be able to run it on 98 anyway irrespective of the E85 that is used.

[sailaholic]

Nothing lazy about the car now either.

That's the best idea, leave it to the professionals. and if it only see's that many K's on public roads then you there would be no point in it, you are right.

Sailaholic - Do you understand how E85 works? in comparison to running E85 98 would be very noticeably lazier. Dann read up an awesome thread on E85 if you can find it

[sailaholic]

Yes thanks Angus, I understand it. I think I even read that thread when it was new.

Having followed marks development of the car and had a chance to have a quick drive my comment was complimenting the owner on the current performance.

I assumed that Sailaholic's comment was a polite dig You need to have another drive with the new tune, it is even more fun

The one thing lazy about the car is me, the driver... but I'm getting better. Hopefully I will get some more seat time before the E85.

Don't 'post' too much, but I feel obliged to do so Angus, to the original ??.
I do run E85 in my red NA not aways affectionately referred to as the 'Turbonator'. When you speak of N Dann running this fuel, most lately that was probably in this car as it was with him for an EXTENDED period for the fuel mapping project, among other things. We had specific goals since I wanted to enjoy both tooling around to work and other things in a reasonably well mannered, but non boring road car, as well as a challenging (even exhilarating) track car. This required dual fuel maps run by a Megasquirt ECU that allows me to use pump E85 (70 octane minimum) or petrol (98 of course) with the flick of a switch.
It had its first outing at LS on Sept 13, managing a 63 sec lap (with my son pedalling it for the 1st time), ran all day while we tag teamed it, and I drove it sedately home. All this from a n AVO turbo N Dann exhausted but otherwise stock (unopened) SNC B6 with walbro fuel pump and big injectors. Apart from the drive home from Newcastle the week before that, I have not run it on 98 since, and can't find a reason to with Caltex E85 at $1.28 at my last top up:)
BTW Angus, I bought the standard exhaust from you (for the replacement '89 I drove whilst waiting for the 'Turbonator's transformation, so more info if you want.

I'm running e85 in my NB turbo. Apart from the ecu capable of managing a flex sensor, there's the sensor itself, larger injectors and higher volume fuel pump. I suspect, the pump and larger 1000cc injectors I installed are more than was needed.

I've only run two tanks of e85 through it at this stage.

The e85 and pump tunes were done the same day, with the e85 tune producing 16% more power and 18% more torque, but with an additional 2psi boost. I actually thought it would produce more than it did, but I've concluded that the previous tune results must have been comparatively optimistic.

The nearest United E85 bowser is only about 15 minutes from me, which makes it an easy adaption.

Assuming you need an aftermarket ecu, it's not a cheap mod, which might discourage many. If I had not needed to replace the ECU already, I don't think I would have spent money on converting to E85. Safety, sticky tires, and suspension mods would probably have come first.

[Magpie]

Thanks The American based on your figures I can expect about 29 more HP and 34 nm. I'm happy with that as all I need to do is add the sensor and have it retuned. However my engine may have a little it more of a gain than yours.

[project.r.racing]

Those figures dont mean much unless boost pressure is known. If you are running relitively normal or close to normal boost and compression ratios. Then you are not using the full potential of one of the benefits of E85. E85 prevents knock alot better than normal fuels. So unless you are gonna wind the boost up to stoopid levels, increase the compression ratios etc etc to where knock would normally occur, then it may not even be worth spending the money converting to E85.

[Magpie]

Mine is NA and running 11:1 compression. No boost...

[The American]

in my case, 8.5:1 and 14.5 psi

I thought the username was familiar! Why are you using Caltex over United? United is more consistent isn't it? In the Nissan world everyone forgets caltex, United E85 or next best is Meth injection. Lots of people even run NOS

That compression plus that boost = awesome.

Thank you E85 for preventing pre detenation.
