yeah bang for buck it's pretty good, ( be better on E85, diff go's bang ) not bad for a daily

2 points higher, if it was actually higher, would make it run a bee's dick richer, hardly worth plugging the laptop in but!

Or get a gearbox full of third........

2 points higher i would have thought be richer too....Alls i know is that fuel will not be going in my daily ever again....E85 on the other hand hmmmm....

Well the United site lists E85 being sold only at United Tapleys, hopefully they will bring it to Salisbury, then ill seriously consider it.

Increasing by 2 points shouldn't make it run like a POS if it ran fine on BP 98 though......different story when decreasing by the same amount.

Apart from running slightly cleaner, the only issue by not tuning to the extra 2 points would be that you would not be taking advantage of the increased octane.

I stand to be corrected by the tuning gurus though. :D

I may be wrong but thought I read the V8 supercars switched to E85 and had a world of issues until they got the tune right. I don't think the RON value is the issue, maybe it's the way the fuel burns which requires the vehicle to be tuned accordingly. I've also heard you will use a third more fuel if tuned correctly thus burning the cost advantage. So ultimately the only advantage to E85 on a standard vehicle would be your conscience effort to support the environment.

^^ not entrily true

Less knock and more power even if it uses more fuel you still get more power

yes but on gasolene more power does not always mean you're burning more fuel. Your engine will burn more E85 per Kilowatt than gasolene no matter what the tune, so the cost advantage is moot.

And FWIW I don't think the v8's changed to E85 because they get more power out of it, I think it was enviironmentaly driven............pardon the pun :D

When peeps convert to E85, cost doesn't even come into it, neither does the environment...that's just a bit of cream on the cake.

They do it purely for higher state of tune that can be achieved and extra boost that can be had without the leaning and knocking that pump gas gives you at maximum AFR's and timing.....hence more power, with only injector and fuel component upgrades needed.

My 34 has been runnig on e85 for daily duties for over 9 months now, and there is no issues once tuning and injectors and better fuel pump gets addressed.

To run this fuel you have to add the supporting mods you cant just put it in and expect more power or reliable operation. I did it properly once and the car runs the same as on pump fuel sligtly smoother at idle.

Your wrong. My car would ony make 280awkw on 98premium, the day i changed to e85 the car jumped to 300kw with no tuning, and then up to 315awkw with a better tune. So yes e85 does make more power, you do burn slightly more of it, and at the end of the day dont give a hoot how much it costs, i was buying it from scotchers at 1.80 per litre but out at mallala the car is always on redline on every gear change without even the slightest misfire or anything.

that's a bit of a blanket statement, which part of my posts are wrong? To summise I've stated so far:

Yes you need to tune to suit E85

Yes you will get more power on E85

Yes you will use more fuel doing so

Yes the running costs will go up.

So what is so wrong with what I said when you just confirmed all of it.......... :rofl:

And let's not forget that I've stated all this in relation to the GP who drive street cars, not race tuned track cars.

yes but on gasolene more power does not always mean you're burning more fuel. Your engine will burn more E85 per Kilowatt than gasolene no matter what the tune, so the cost advantage is moot.

This bit :P

then I'll make the blanket statement and say YOU are wrong. :rofl:

The press release:

E85 fuel supplier announced

Friday 10/10/2008 13:10

V8s at Phillip Island

CSR Ethanol was this morning named as the official fuel supplier of the V8 Supercar Championship Series for 2009 and beyond.

V8 Supercars Australia Chairman Tony Cochrane joined Ian Glasson, the Chief Executive Officer of CSR Sugar – an associated company of CSR Ethanol - at the Supercheap Auto Bathurst 1000 on Friday to make the announcement.

While this year V8 Supercars use a five per cent ethanol blended fuel, next year they will run the E85 fuel which is an 85 per cent ethanol and 15 per cent petroleum blended fuel.

The safety cars will also run on the E85 fuel, which is made from molasses (a byproduct of sugar cane).

“This is one (announcement) that I think we’re particularly proud of at V8 Supercars Australia,” Cochrane said.

“It’s not only a great day for our sport, it’s a great day for the environment, and a great day for renewable energy here in Australia.

“What we consider is one of our key roles in all of this quite frankly is to help educate over the next five years the Australian motoring public in particular.”

Glasson said E85 fuel will substantially lower the greenhouse footprint of motor racing.

“CSR Ethanol is delighted to be part of V8 Supercars to improve the environmental footprint of the sport and also to establish ethanol as a very credible fuel, not only in V8 Supercars but across the Australian motoring public,” he said.

“Every litre of E85 produces about half the greenhouse gas of traditional fuel.

“That’s a very significant improvement and not only is it sustainable but renewable.”

So not environment driven then !!!!!!!

Edited by mosoto

the teams mechanics dont give much away while looking for any advantage they can get, atm they are more interested in economy than power and since e85 can be run much leaner before shit melts thats the direction they are playing, IMO the teams who can afford to run leaner will win, triple 8 have the advantage here because they have lots $$$ and can push there engines further

V8SA's green theme doesnt seem as friendly if someone mentions performance

Your missing the point. A car wil get as much as a 40kw increase by switching to e85 over premium.

Im not fighting the fact that it is an enviro fuel. All im saying is the prformance benefits are quite large. So if you think tyres is what make horsepower in an engne than thats fine. Id rather beleive what my figures say than someones press release.

    • I'm seeing torque specs all over the place for the OUTER tie rod, but none for the INNER tie rod, where it connects to the steering rack. Even in videos, people are just tightening em up as much as they can with a wrench and that's it. Anything tightened down without torque makes me nervous. Anyone know what the spec is for it?
    • Hope you had a great time here in our tiny country.   The JDM scene we have here is quite small, it's mostly BMW, Volkswagen with burble tunes haha. But the few JDM cars we do have in the scene are pretty nice. Some of my friends drive cool s14's too. Both built engines, red one makes abt 500, blue one abt 400 i think?
    • Ye good idea , would have never thought of something like that. Might aswell do it to every pulley and the balancer while I’m there 
    • Use an LS1 or similar, via kit like Frenchy's. But.... It's probably not the alternator. It sounds like belt squeal, which would be because the pulleys are glazed. Rub every groove on the pulleys with 120 grit paper. Report back. Oh, and new belts afterwards too. The old new ones will be shitted up already.
    • Hello all I have 2 r34 sedans , one turbo one na, only recently aquired the na 34.  Man what is with these things.... My turbo 34 started sounding like a super charger, it was screaming at anything above 4000rpm , I took the alternator apart and replaced the front bearing which is the only one I think you can access and it did not fix the issue so presumably the bearing in the rear of the alternator is gone. ( diagnosed it was the alternator by taking off the aux belts one by one to figure out which pulley or bearing it was )  My friend gave me one he had lying around, Installed it , it did not squeal for maybe 500kms and now its started to squeal again briefly on startup  Recently got an na r34 and I replaced the timing belt, water pump + all the auxillirary belts. Runs amazing but it suddenly developed the same squeaking problem but significantly worse, Ive had my neighbour come down screaming at me because it was waking her up everytime I moved the car. It takes a good 2 minutes before it quietens down.  Im yet to diagnose where its coming from but im fairly sure its coming from the alternator aswell. My question isnt about how to fix it but rather where can you get a new alternator for an rb25 neo??? Ive searched everywhere but I havent been able to find a direct fit oem type replacement thats not genuine. All the automotive stores sell an oex one - BXA035 - which I picked up for cheap through a friend with staff discount , got it home only to find the connector is completelty different.... As far as im aware bxa035 is for rb20/30's and after a bit of figuring out the bxa035 has an ev14 type connector, which is tiny compared to the rb25 connector. I actually had an ev14 connector lying around which I was considering just replacing the bigger plug with to get the alternator working but the bxa035 is rated for 70amp vs the rb25 alternators are 90amp ( or so ive been told ? ) That paired along with the fact im about to install an amp + sub in the back and I have the stock sized small battery Im not sure itll do the job unless anyone has another opinion?  I know and have seen all the websites selling the ls1 alternator conversion kit but I am not going down that route, nor do I have the money to. Hopefully I can figure out how to get 2 brand new alternators for both cars. I would buy second hand which there seems to be many of but considering how common this seems to be im sure If I installed a second hand one it would start squealing in no time  Or even better if anyone knows how to fix the issue directly with the alternator itself... Any input appreciated Thank you     Link for bxa035 connector picture
