Yep, test and see the difference between 0.80 and 0.85ish whilst paying attention for detonation. If the gains are considerable and detonation doesn't rear it's head, all good.

Just goes to show how big an overkill my 910's are! At least I'll never have to upgrade them again. I'd certainly expect an improvement in reponse tuning for E85 and using the Stage 5 housing. How much of a difference there would be between the Stage 3 and 5 (power vs. response) I really don't know. If only it was a 5min' job to swap them over... again. Plus my Stage 5 housing is internal vs. the external Stage 3. I'd really like to see how the Stage 3 wheel + Stage 5 housing combo' would go. Then again, as it's been over 2 years since I started this turbo set-up, I think I'll just enjoy it for now and concentrate on other areas of the car for a while - more interior trim work commencing 20th Feb Shaun at Boostworx did the current tune. He added 7' on the ramp and 5' up top. Further additional timing up top didn't increase peak power (0.Xrwkw only) extra boost only added 2-3rwkw. Slightly leaner up top might liberate a few more kw - 330rwkw maybe. Sounds good mate.

Thanks for the comments guys. Adrian, yep pretty much. The Microtech displays duty cycle in milliseconds. To be honest I can't actually recall what DC figures we were seeing, certainly less than Max Duty (the handset flashes MD if you run out of injector) I'll get back to you next time I go for a drive and will drag up the peak figures from the data logger. Very similiar territory with the A/FR: 0.80 Dave, I am running a single internal Bosch '044 pump. I'd say the limit is well over 330rwkw. I recall reading a Bosch '044 will support ~350rwkw on E85 - not sure what base fuel pressure this was at. Lee, I'm still reluctant to switch back to the larger Stage 5 Turbonetics housing - trading less response for another 30rwkw top end.... hmmm it's a hard one. I still remember driving the car with the Stage 5 housing last year and hating the docile mid range. I just don't think E85 could improve it enough to give me what I want. Sounds like a good plan. Hopefully I'm free that weekend. I just wish we had a functional drag strip in Adelaide. I would love to see where I'm at vs. the old numbers in my sig' - I ran those numbers with ~260rwkw @ 420Nm and a very good spread of mid range torque.

As I wrote above, my '33 is finally up and running on E85. I'll cover off on what I think are the main points first: Despite running the 'humble' Microtech LT12, it starts first go each and every time and idles away nicely at a slightly high ~980-1060rpm - this is with mild HKS cams and 910cc Siemens injectors. A/C idle up is also no problems. My small Turbonetics 0.63 Stage 3 housing is well and truely at the limit, however, I am happy enough with the trade off in response vs. peak power. I would have prefered another 15-20rwkw peak power, but I downsized from the Stage 5 housing due to less than acceptable response - Stage 5 would support ~350-370rwkw but require 5000rpm before making decent power. The increase in off boost torque is noticeable - picked this up by seat of the pants immediately! 7' extra timing is the key here. Peak power has increased by a mild 25rwkw, mid range by ~40-45rwkw. Power and torque is up across the entire rev' range etc. I am seeing 15psi @ 3300rpm, 20psi @ 4200rpm and peak boost at 4600rpm. Spikes to just over 24psi before dropping back to just over 22psi. Also holds a nice spread of peak torque, or near enough to peak torque, for ~1000-1500rpm in the mid range. I've stocked up with 5 x 20L jerry cans of E85 - seems to be in short supply in Adelaide at times, so figured I'd keep a small stockpile. It should maintain a 'shelf life' for at least 8wks if stored correctly. It was also decided to scrap the idea of back-to-back testing Martini 110 vs E85, time was the main factor here. Apologies to anyone that was keen to see the results. Dyno sheets attached* *The savage flucuations in the before dyno runs were due to a combination of things - Mickey Thompson ET Street Radials don't like knurled rollers!

My '33 is now up and running on E85 (more info'/dyno sheets to come shortly) and I am still using NGK 7's iridium plugs - no issues whatsoever. Mid winter night time temps might uncover fouling issues, but I doubt it.

Brief stints at those temp's are nothing to be majorly concerned about, but if it's a regular occurrence I'd be looking at rectifying the situation, GT. It's not something simple like a dud radiator cap is it - I know it's one of the first checks you would do, but I thought I'd ask.

Ha-ha. He's a man with a memory like an elephant. I was considering upgrading the cement to top quality 300*300*40 pavers, as not only do they give a nicer Autosalon style boot display, but they also allow more adjustment in weight distribution

Cheers, Hamish.

I'll add my 2c too. We finally fired up my RB25DET at the end of last week using 910cc inj' and running E85 for the first time. Scaling ~25% fuel out of the map for the old 550's saw it start up and purr away like a kitten. And now that the Adelaide temp's have dropped from 'insanely hot' to mid 20's I'm expecting a dyno number sometime next week. Still have to do a bit of tidying up after the rail and injector change, but it all looks neat enough.

jet R31 (Darren) a semi-regular in the South Aust' section, has a full weight R31 with a RB30ET and GT42 combo'. Last year this car ran 10.2 @ 140+ with ~440-450rwkw on a Dyno Dynamics dyno. And from Darren's info... the car had more top end in it (transbrake caused issues that held the car back a touch). There's no doubt that Regan has a solid engine package, and no doubt it has the grunt to run 11.1 @ 132, but in direct comparison to the 'average' Dyno Dynamics dyno here in Aust' his 446rwkw figure doesn't add up. R31/ RB30ET + 440-450rwkw = 10.2 @ 140+mph R33 / RB25DET + 446rwkw = 11.1 @ 132mph I doubt the somewhat lighter R31 would gain almost a second and 8+mph!

NPL = Donkey City. No offense to regular NPL players No cash riding on it and it just becomes laughable. Give me real money game any day Last year one of the top 5 SA NPL guys came to a 'mates' cash game. He lost the lot by nights end. Cash games have a greater skill component vs. tourney - increasing blinds force you into situations, cash you can sit back and decided your own fate (luck can still desert you at inopportune times though). I've had a bit of a look at the ANZPT stuff on PS, but haven't taken things any further than that.

Yep, Evaporative A/C systems are pretty much useless in humid climates - NSW, QLD, NT, Northern WA etc.

You know it's warm when it finally drops below 40'c at 2049hrs, only to reach 40.2'c again at 0300hrs. As for humidity, this place (Adelaide) doesn't get 'real' humidity... I'd rather 40'c and 10%, than 35'c and 95%.

Updated / bump

I'm the same mate. Between my Plazmaman plenum, ETM manifold, numerous other custom alloy and stainless gear I've had done, and an all signing and dancing $20k welder we've recently ordered in at work... I also have one hell of an appreciation of professional welding skills! Leigh's welding abilities are in another dimension in comparison to my capabilities.

Good choice with the plenum and the ETM products

What really blows me away is it's making that power on 'mere' Nismo 555cc injectors and standard fuel pressure (OEM reg still fitted) Absolutely crazy results!

Thought that was you. Yep, saw the black and white R33's. James and I are mates, I was chatting with him when you walked through the door (I was one of the guys in uniform - not the blonde one). James is flat-out at the moment, so he would have struggled to fit you in I guess this loosely fits the spotted thread - I spotted the person rather than his car

Mitch, did you by any chance drop in to see James at Nisspeed a few days ago (might have been late last week, or earlier this week - can't recall) asking for a quote on a RB26 rebuild? I could be way off, but your engine issues sound very similar to someone I saw at the workshop.

About what I'd expect from the removal of the cat' convertor - hiflow or not a cat' convertor robs quite a bit of power. Race track only mod' though. Awesome figure on 555cc injectors and standard base F/P! Any idea about the mid range? Just a dyno thing, or has it actually lost a tiny bit of low down - mid range grunt?

Good to meet you , Reuben. No problems at all. I was waiting all of 2-3mins.
