after speaking to geoff, he informed me that getting the fuel from csr was impossible as the big fuel companies have signed contracts for the next 6 months preventing anyone else purchasing e85, however they are not using it themselves... and the contracts are probably going to get renewed.

FARKING CARNTS!

update:

filled up with a tank of fueltown e85... which is supplied by powerplus (racefuel manufacturers)

the first thing you notice is the differing smell... its not as sweet as the CSR (united) blend, and smells a lot more "fuely"

we threw the car on the rollers and the AFR's were out by 1 (richer)

we tuned the car for the new blend, and ended up pulling out 10% fuel and 5 deg timing on the top end for the SAME power...

same dyno, same tuner, and pretty much identical ambient temps :)

i spoke to the guy that got fueltown onto 85 and he was saying that united rate their fuel at 104 ron, and powerplus call theirs 106! (the pump however says 104+ just to be on the safe side)

the differing smell is due to the fact that powerplus use wheatgrain ethanol, whereas CSR use sugarcane ethanol

both fuels are blended with 91 ron.

we did a comparison graph, with the CSR and the powerplus fuels, but i forgot to grab a copy...

next week when i'm back at status i'll grab them and upload them unless trent beats me to it :)

For the southland E85 Power is the same, but needs 10% less fuel and 5 degrees less timing to get said result. (red line represents first run with old e85 settings, too rich and too much timing)

im so glad you victorians get a choice of what e85 you can run... we don't even have it on pump :)

Still don't? Jebus... that's bad... :huh:

But then i live in the CBD basically here in Melb... as an example to get to Hoppers (where one of the servo's is) and back would see me using a 1/4 of a tank just to fill it up lol.

So whilst we have "choice", doesn't neccesarily make it instantly viable. A Sunday driver ye, anymore than that forget it IMO.

Friend of mine used to take two jerry cans with him just to 'justify' the trip even then there was one trip a month being done (car was only driven twice a week, not very far)

Hamish - given they only rate it 104+, various batches might change between 104-106 by the sound of that statement.

3 months the blend might die down a tad. At least the United seems to be extremely consistent... Fueltown might not perhaps.

Just something to consider.

Where is Fueltown btw?

Id also be interested in what e85 could do with a stock turbo? any ideas Trent??? im running 13psi at the moment, so theres not really any room to increase boost i wouldnt imagine

Im in St kilda so fueltown isnt too far at all! and the car is only a weekender so it wouldnt be a hassle fueling up.

Im ASSUMING the injectors and stock turbo would be the main things holding me back? ive got an aftermarket fuel pump, which would be fine.

Would there be any worthwhile gains to be had???? if there is, ill be knocking on your door Trent!!!!

R31Nismoid dismissed me asking this question in another thread. Overall consensus of e85 fuel was that you seem to be able to get more power out of a particular sized turbo then what you should. Therefore its better to go on the smaller side for a particular power level.

Although R31Nismoid does have a point that a full retune is quite costly and there would be better ways to go to get more power (upgrade turbo).

As you said the problem will be the standard injectors as you need 25% more flow just to maintain your current power level.

And is it worth the risk of potentially ruining your turbo.

seraphyn_r33 - you would run out of injectors before you make any use of E85 on a stock turbo unfortunately.

So you would retune, and not make full use of E85 without fuel.

You should get around 230rwkw on a factory turbo with E85 @ a rough guess

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
