I'd be after a lowmount for a rb25det but need to save some pennies first...

holla at me when ya do

[Seano350GT]

32?

35 man

[89CAL]

All 35's are sexy

[Seano350GT]

Indeed, but i'd never seen one in the flesh. Pretty sure it was stock standard, it had the LED's at the front which i'm not a big fan of so i think it's a 2009-2010 don't those years have the LEDs?

So nice but!

[Stewie Griffin]

35 Sexy?! If your into fat chicks that are really, really good in the cot. But whatever floats ya boat i spose

Tell me you wouldnt have this:

There are prettier cars that have come out around the same time as the GTR, but there still a nice car

[Stewie Griffin]

Yeah I'd have that and sell it to buy a 34 ztune, resprayed in midnight purple 3. Or even a de-stickered mine's 34. 35's are like the half decent looking fat chick you take home after being knocked back by the hotties. But if money really was no option, the original maclaren f1. In silver. Side profile looks like a silver .223 round, should be hunting down werewolfs.

[Seano350GT]

I disagree, i think the GT-R's in white look amazing.

[89CAL]

Just had a thought now driving past Caltex Nebo road. They are ripping everything out of the ground there. Are they bringing E85 here?

Or did they have a cracked tank etc and are just doing boring maintenance?

[The Mafia]

I've seen that many times too. I am hoping they are bringing E85 there since the tanks are being dug up.

I'll be buying something forced ASAP if so.

I be it runs out all the time though

[Seano350GT]

Pardon the very uneducated question but what's the difference between say E85 and premium unleaded 98? I have no idea..

[89CAL]

E85 is higher octane rated, burns slightly cooler and u can bump a bit more timing into the tune (From memory these are the perks)

down side is it isnt as economical, but it should be cheaper

[Robi33]

From whst I've heard, they are just renovating and putting new tanks in. The only service stations that have been intetested in E85 is the BP and Shell at the city gates. Only because of Palmyra's location though.

[89CAL]

United should do it, would be alot more people going there then I think

[Nur33]

E85 is 85% ethanol and 15% petrol, octane will be over 100 and the ethanol is good for running more boost and timing a bit more detenation resistance the Sucrogen E85 we use in the R32 is more refine with better quality petrol it is 109% octane. Down side to E85 is you need bigger fuel system with better flow and it burns up nearly twice as quick as petrol so if you average 500km per tank on Petrol you will probably get 250km a tank so your range is halved

[89CAL]

I didnt think fuel economy was that much worse. I thought it was around 20-30% worse?

[FineLine]

On a 600 hp 25/30 I can still get 400 kay to a tank on pump e85. Octane rating is 104,

driven sensibly (stay off boost) fuel economy is sweet fa different to 98 unleaded, Its only when you open the tap that it starts to drink like a sailor.

If you have it available just use it. your engine will run better, plugs last longer and it smells like a rum distillry, (i like that)

This is where I can help - Chemistry was one of my strong areas at school. Always had an interest in it.

This is a Ethanol Molecule:

This is a Heptane Molecule (The most common molecule in gasoline)

As you can see, there are a lot more Hydrogen and Carbon atoms in gasoline (These are called carbon chains), so technically you'd need 2 x more ethanol molecules to take up the same amount of weight as Heptane is twice the weight. You should see diesel - its twice as long again.

When you add oxygen (o2) with Heptane, compress it and add a source of ignition, the carbon chains break down via a chemical reaction and re-forms into co2 +h20 + energy (and lots of other nasties due to the additives in the fuel). The reason these chemicals do this is because of electron shells, and wanting them to be full and stable. (Electron shells are another whole chemistry lesson, haha)

here is stoichiometric: or simple terms - (Thanks wikipedia)

This is is a fairly simple maths equation. If you count the amount of carbon atoms in the Heptane molecule it helps you understand this equation better. You can work out how many oxygen molecules are required to burn a molecule of heptane. If you did chemisty you would have learned this back in school! haha.

Anyway, ethanol is more interesting in the way it reacts with oxygen under pressure and an ignition source.

Ethanol -> C₂H₅OH_(l) + 3 O_2(g) =^Heat=> 2 CO_2(g) + 3 H₂O_(g)

_{Gasoline ->} 2C8H18 + 25O2 ~> Heat=> 16CO2 + 18H2O

Ethanol being smaller, having its own oxygen molecules, and being more "chemically satisfied" means that you can compress it more, and with that extra heat due to compression it is more stable and less prone to becoming unstable and reaction on its own without control (detonation). The extra oxygen molecules also help it also burn cooler. It also produces more energy so the idea of using double the amount on light loads isn't entirely correct. There is an exact way of figuring it out but I CBF'd doing the maths right now. Once any engine is on heavier loads, power starts to simplify and mostly rely on the amount of fuel and oxygen that can pass through, and efficiency.

In a nutshell, you can cram more Ethanol into the cylinder because, meaning you will use more, but you will also make more power. If you can't make more power because of engine \ airflow \ other limitations, then you won't use more.

The consumption is really based on power output. For example - Bennys GTR would chew the shit out of it because its making bulk power

There is much more to explain and I'd need hours and a white board to explain but this gives you a good idea of the differences. Google also helps a lot if you're looking for information on the chemical reactions.

I love E85 and the chemisty behind it and I wish they would replace all bowser fuel with it as its much better for the environment, and our precious engines. Oh, and there is almost no soot!

To the people that don't know me and make up shit like I read a few magazines to learn how to tune (They know who they are) and think they are cool posting lies on facebook, keep living in that muppet \ sheep lifestyle of not having a clue. I'm more than happy to see you burn money on tuning elsewhere. I'm 8 years into tuning and my friends \ customers are quite happy with the results.

To the rest, give me a call if you have any questions, I am more than happy to help

Hahahaha. No post was aimed at you. People who commented on it made it about you. Get over yourself.

And lets get some facts right... There are a few of your 'customers' who have not said a good word about you at all. Enough is enough. Stop blowing your own horn. You don't see other tuners preaching about themselves, do you?

You tell me to get over myself, yet there is nothing for me to get over. You are the fools trying to prove some bullshit point. I'm simply confident in my work.

And dyshonest, the man how winds the f**k out of his timing, blows the f**k out of his head gasket, and then sells it to some poor unsuspecting person as a perfect engine... Then bags me out as a tuner. oh the irony.

I'm astounded at the "dyshonesty" alright...Was a dog act. And you're his sheep, you and your Chris mate.

its ok, good for you.

A few of my customers? Let me guess, Blocka, and the Ebay turbo that wouldn't make power beyond 200rwkw because it was a peice of shit, proven by 2 different tuners? I can't help it if people get scammed and buy shit that won't produce the flow. Good for you though. If you want to talk about mis-informed shit, thats your problem I guess. You're a sheep.
