sorry if its been covered but why the ~200rpm difference in reaching full boost? actually different with e85 or just different ramp rate on the dyno?

interesting results, wish one of the servos would hurry up and start selling some over here, keen to experiment

Exact same ramp rate, the E85 seemed slightly lazier but here is another graph which is more indicative as the two runs i've listed here were within 5mins (the time to swap fuels)

I've never really thought too hard about the cause of this kind of thing when tuning with alcohol but it definitely happens. I'd say at least part of the reason would be the increased (even if just slightly) amount of volume passing through the engine and as such, through the exhaust system.

We got 200rpm better spool when we tuned an RB20DET R32 running a T3/T4 on an E33 mix recently, interestingly we got an extra 40wkw on roughly the same boost level with that conservative a mixture of ethanol - and making big modifications to the fuel system wasn't needed either. I'm quite tempted to do such a tune for my Skyline...

Trent do you know where the cam gear were set? Joey previously indicated they had been adjusted and I am curious where they ended up.

Looking at the results of this thread has got me pretty excited and pretty bummed out at the same time.

Bummed out because I do not have access to any ethanol in this country (if you have kept up with my current adventure you would understand) .. Excited because I can see all the testing and time I have invested in e85 last year is paying off, there seems to be a big e85 trend going on since I stuck my neck out and tested this stuff in my car, Just search for E85 on google.com.au and you will see how many other forums are linked to us here at SAU.

Looking at the results from Trent @ Status Tuning - URAS has backed up everything that I have found on my initial testing of the fuel. I found a 40 - 50 rwkw increase with my setup but I was using a bigger turbo charger so you cannot compare them with this setup 100% but it does show that when you have a experienced tuner working with this fuel you can see major gains with no other modifcations as long as the fuel system is up to the task then you will have gains all across the board.

It is good to see that you guys are still working on this boost juice, without the support of tuners like Trent and enthusiasts like Joe Joe, Nytsky and Now the all famous Dirtgarage (AKA Twoogle and Mark Jacobson @ Godzilla and a few others like Yavus @ Unigroup Engineering and even JEM) it really puts SAU first in line in Australia for for this remarkable race gas in a pump for only 0.99c a litre.

So yeah, I am sure I do not only speak for myself when this warm fuzzy feeling of E85 love gets its share of internet hits... Its because of tuners and and enthusiasts like us who make it happen.

Keep up the good work! Someone needs to try and and push a complete stock RB25DET to as much power as possible with this fuel... are you up for the mission Trent? :D Can anyone say 400rwkw ?

:D

Yup sponsorship drive is on for next year, dont be suprised if its sexyland, AMI, 4SEASONS etc.... AMI's nasal delivery spray budget is huge... how many billboards are around? 1000's. If you look next to it you can see wrigleys and haynes manuals are also listed

ok ill pay that :D

haha i had to edit the first one as i thought you picked up my spelling mistake "tuune"....... then i realised it wasnt that funny.... so i looked again and pissed my self lol

gonna go e85 on my ke70 too.... what kinda gain ya recon i'll see on an n/a 4age with quads and cams?

no idea! But will be very interested in what you find with the NA engines and E85

well as soon as i can afford an ecu and cams i'll be posting the results in my thread :blink:

any idea what kind of gains the holden boys have been seeing?

i really want to try to get it to around 120rwkw n/a

the other idea i was toying with was dedicated gas...

well i have the fuel system & injectors to run e85 as i always planned on running this e85 stuff 1 day - my tuner also recommends it :blink: he told me about an increase of 50-70awkw would be within reach for my setup which equates to approx. 15-20% power increase...looking at joejoe's results this seems about right!

if only i could get this fuel from more than 1 servo in sydney (united in drummoyne) i'd be in @ my knees

oh & congrats joejoe on your results!

    • Thanks for taking the time to post that ! If anything changes or happens please do update us. 
    • Somehow Vertimass/Oak Ridge National Labs has figured out a catalyst that can convert ethanol into C9-C10 hydrocarbons in basically a single step without ending up with a bunch of ethylene or similar waste products: https://patents.google.com/patent/WO2023224867A1/en I still don't think anything like this will keep us from needing to transition to EVs regardless along with all kinds of other electrification, but things like this will go a long way towards alleviating the problem of how to electrify things like planes. Renewable diesel is seemingly an easier problem as well, Chevron is already running refineries for the stuff and the primary feedstock is tallow and other waste fats from agriculture.
    • Ok so I have sorted everything with my uniclutch and  i can offer up a bit of feedback and some things that might help others.    I found problems with factory damper line. Weird shit and had trouble with peddle adjustment    I used this https://au.gktech.com/products/r33-gts-t-skyline-braided-clutch-line?_pos=2&_sid=22b01b9b9&_ss=r Also when adjusting peddle leave a bit of play. You can get into a over stroke condition easy.. Make sure you can push the slave forward after adjusting to confirm fluid can return to master then you will need to pump it up heaps…..not sure why but that’s how it is.    last thing the splined adapter is machined perfectly. If your input shaft is old like mine was I would put a bit of valve grinding paste on it and stroke it like a 15 year old. Just to give it a tad more clearance and to better match it to the spline.    reason is on a near flat shift I have had situation where the peddle returns a millisecond after you lift from the clutch. No slip or anything but I reckon this is due to tolerance on the spline being way tighter than stock clutch and binding for a sec. I think this will go away but also my spline was old. Box is old so I guess I should have checked better. It’s a super neat fit.    it feels light as and holds awesome without any noise    
    • My Fuga Hybrid is JDM, 2014 model but very similar to the V37 from the looks of things..same platform just physically larger and very comfortab;e
    • Was that Australia Delivered Duncan? Does it have siren etc?   I used to have remote start on an old 32 two decades ago, it was a cool feature. I used to wake up early in winter for work. Start it and by the time i was out the door a few minutes later the engine was warmed up and the heaters had the car toasty. It was great.    I don’t mine the ambience lighting.  I drive a western star and it has footwell lights and ambient lighting and it’s great! From the pics of seen of them installed in a skyline I think it’s a nice touch
