There's still only one servo to get it from in NSW... kind of limiting.

Ye same for us :down:

I never saw PULP mentioned before you, Nismoid - I thought E85 is pump gas in Oz these days, too? It is showing up a lot around the world....

Well 700cc injectors gives it away, you'd need 1000cc or bigger using E85 :)

There is only a couple of servo's in Melb.

To give you an idea... The closest to me (and i live basically in the city), is 30mins drive one way.

If some one says they want a certain amount of power, i think we need to assume it is on 98 octane. It is a bit pointless telling some one they can make the power on "x" turbo, they go an buy it, try to make the power and can't. Then when they come back you say "oh sorry, i ment it would make that power on C16, E85, Nitrous..." etc.

I also wouldn't classify E85 as pump gas in Oz.

Couldn't agree more.

E85 is like saying you made that power on C16 - utterly irrelevant for most people being you can't get E85 anywhere in most states.

and that is that...

Maybe you should read the first post then?

700cc injectors

i want a single top mounted turbo and want to make 350rwk

700cc injectors should manage it on e85...

but either way i agree with pm-r33, when people ask for a power figure, its PULP unless otherwise stated...

Fair enough, I wasn't sure if E85 was quickly becoming the new premium or not - I'd imagine if it came out here we'd all be getting tuned on it. I know everyone who has access to E10 here are doing so :down:

It was meant to spread to heaps of servo's here in Melb really quickly... this was around 12 months ago for Melb.

Since then not ONE of the servo's marked for E85 have started stocking it yet. Just the original few... So something serious must be going on to stop this becoming more widespread as it is a massive money maker. Few discussions with friends etc we roughly think its more profitable than PULP so why a company wouldn't adopt a more profitable product must mean there are issues.

Either way - assumption always is PULP. We've never assumed it was C16, Sunoco104 or anything else in the past... to magically start now is silly.

Slightly different, E85 costs less than PULP per litre and officially could be available from the pump... so quite different from race gas. But yeah I get what you are saying.

I find it interesting that no one over there has managed to get more than 320-330kw @ wheels out of one on pump gas, though I am not sure exactly how harsh your dynos are. In the states there are people who have done around 350kw or so on PULP on Dynojet rolling roads and Dynapacks. Either way, I'd call a GT3582R more suitable for 350kw @ wheels on a drift car - you're going to be in high revs most of the time anyway, surely?

dyno jets read quite high and ive noticed the us guys tend to qoute flywheel power when using dynapacks (they use the TC factor caculator)

The issue with E85 seems to be the storage tanks,no one wants to cough up for the required tanks and subsequent regs etc..

Out of curiosity what car is this RB26 going to be in ? I'm guessing a GTR wouldn't be such a good drift car ?

Probably the real thing to to know is what is "adequate" power output because if 350 is too much sizing a turbo to suit is a little pointless .

Now I know nothing about drift but if I again had to guess I'd think real strong mid range torque with good throttle and boost response - to the hoof - would be everything .

I'm thinking the "burning" question should be how much torque and how accurately can it be modulated .

Not my money but would an RB25 with a supercharger be simpler/cheaper ?

superchargers generally suck unfortunaly we do alot of superchargers on v8's and so forth and it is suprising how laggy most of the popular ones are.. makes a T51R look responsive :down:

Yes Trent is right!

The issue with E85 is the cost of the replacement tank lining. I was told it costs 40 GRAND per tank upgrade so as you can imagine who is going to spent that kinda cash on a upgrade that will not return the money for at least 5 - 10 years ?

It is also a legal requirement to have this upgrade to be able to stock E85.

Wait till holden brings out E85 flex. Things will change very fast.

My RB30DET ran out of injectors with Nismo 740cc at around 345 - 350 rwkw (mainline dyno)

There is plenty of info on my E85 thread about this stuff.... worth the read.

Yep :P

Fact. A GT3076 will not make 350rwkw on PULP. Nor will it make 360rwkw, or 374rwkw on PULP.

Fact. You will not make 350rwkw on E85 with 700cc injectors, nor will you make 360rwkw, or 374rwkw with those injectors.

Fact. A GT35 will do make 350rwkw on PULP with 700cc injectors, which is the question that was asked.

It's not the 'most responsive' option, but that power goal is in a little bit of no-mans land. However if you are drifting, the first 3500rpm of a tacho is rather pointless anyway.

Overall it's laughable to think E85 results (a specialist fuel no different to C16 at this stage, if anything C16 is EASIER to source) were brought into this thread just to try and backup incorrect facts...

And then try and call 'ignorance' :)

Shows how ignorant those with the incorrect facts really are.

lol

just to prove your "facts" wrong... i cant wait till conan7772 gets bigger injectors, pumps a extra 1-2psi into the motor and makes the extra whole 13rwkw to make 350rwkw on pump fuel no less

Guilt-Toys car was making 345-350rwkw with Nismo 740cc's on e85 bump the fuel pressure a little with a reg and you will make more with 700cc's

Noone said that 35R's will not make the power...

I could make 360rwkw from GT-SS's if i want, doesn't make it true though does it?

From page one incase you've forgotten it, again. :P

I couldn't care less what a dyno says until there is some real proof to back that up.

Of which, as usual, there is ... zero.

But then you do love your arguments without real evidence :P

Lemme know when you have the evidence, i suspect though... we'll never see it.

A GT3076 isn't going to make 350rwkw in a .82

Al has maxed his out @ 306rwkw or there abouts.

That is a solid 50rwkw shy really...

NYTSKY made 362rwkw with a 3076R and Denzo just made 374rwkw the other day...

your ignorance is always bliss

Oh i see it is E85 - well that comes as little surprise, everyone seems to make a solid 40-50rwkw when changing from PULP (which everybody has access too), to E85 (which a lot of people do not)

It is not PULP 360rwkw...

There is no way the OP is going to make 360rwkw on E85 with 700c injectors, so he is clearly talking about PULP.

So its still back to exactly what i said, seems im not as ignorant as you are silly to put E85 results into a PULP thread... but that is fairly typical of you. :P

epic lol...

r31nismoid: 3076R is not going to make 350rwkw

cerbera: here are 2 that made more than 350rwkw

r31nismoid: i dont believe you, therefore your wrong

r31nismoid: *finds out he is wrong" epic backpedal and changes topic to e85

      Biggest thing is you're okay!   It sounds like between the accident, and the drive home, it was a pretty torturous trip again! On the bright side, you took the opportunity to enjoy the event more from the perspective of a spectator, than as an entrant!   Sad to see so much damage to the car. It really has taken a HUGE hit in the front end. If/when you choose to repair, hopefully the rails are straight (At least from shock tower backwards). Hopefully the extra cage coming through there has save most of the chassis rails, and HOPEFULLY saved the motor too. Best of luck when you eventually get motivated to start pulling it down to check it all out

      Slight brake pedal stutter after new pads

      By MBS206 · Posted

      Sounds more like what Brad said, that it's mainly transfer. What pad bed in procedure did you use, and did you replace/machine the rotors, or just swap pads?

      Slight brake pedal stutter after new pads

      By PranK · Posted

      The stutter is almost entirely in the pedal. I don't feel the brakes release and reapply as you would with ABS engaging but the pedal feels that way, without the brakes releasing. It only lasts for less than a second and the pedal is fine again. It's hard to explain, sorry.  I'll get under this weekend and just double check everything is tight. Fluid is at max where I left it.

      By MBS206 · Posted

      What bedding in procedure did you use?   When you say stutter, what exactly do you mean? Like it feels like someone letting go of the brakes momentarily and regrabbing them again to get you to stop? Re-reading your post, and that is what it kind of makes me think you're explaining, like theres a little bit of a jolt, likely just as you're reaching a stop. I've only had this issue once. And if its caused by what caused mine, you will want to get the car up on stands again and check it over. Mine was a case of a caliper mounting bolt coming out and letting the caliper rotate on the other remaining bolt and gave play in a wheel as it came to a stop. But not every stop either!

      Yeop... binned it   This will be a summary will not many pics atm and cbf  Fixed the samsonas - it was totally munched Put a new precision 7675 T4 on with proper split pulse mani Got to Sydney to get to car - drove to canberra to get racecar - drive back to sydney that night Next day all day at Plasmaman putting on new clamps cleaning some things up and adding another large engine oil cooler sitting at the rear above diffuser to keep things cooler Next day - Tuesday - on Dyno - killer wikid awesome pumped out really good numbers - more mid range and on lower boost levels Wednesday - first prac - all day again getting the suspension right - had to borrow front suspension again - out do a lap come in - out do a lap - in - what i had just couldnt handle the load at the more consistent higher speeds - got a lap in at the end of the day that was pretty reasonable  Put it this way that lap wouldve had me in 4th in Pro am for the whole event - with only 700 hp and used tyres Thurs first official prac day - lap out warm up - then entered a hotlap with above setting and 80% effort took corners 1,2,3 and into 4 car felt awesome -  rear came around out of nowhere bang into the wall near front on at whatever 140 kmph Done, over, gone Just one of those how did that happen apparently as all indications show nothing out of the ordinary Got to spend the rest of the time at the event like I hadnt done before - was actually Ok mainly as I had my family and my boy is 9 and got treated like a rockstar Long trip home, lost a trailer wheel in nowhere land, X5 airbag suspension gave up half way across nullabour and rode on bumps stops (its now completely fine) had to do a 19 hr drive day on day 3 as accommodation got screwed up so just had to keep driving till found a town with some Now to reassess - hopefully the motor and other things are OK but yet to be seen too. There is no easy fix there is no i'll just order that part and get it sent - we'll have a talk to people see what can happen and what the go is but at minimum its rebuild from scratch struts forward and alot of time effort and $ should and if I return and if but maybe/ when  I have the cage tied into the front strut towers - if I didnt have that things couldnt been worse you can say its just a front end but if you know what goes into these cars... you'll know what that actually means in reality   Car was very fast. Disappointing we just didnt get to show it Effort doesnt win you races though     Apparently this is motorsport !
