Hey Rob, congrats on the power hehehe
Now hurry up and get some FIC 1050cc, heard they are pretty good, or just find some FIC Bluemax 1250cc just to be safe

Also the new 400lpm Walbro intank pump will be nice, where did you purchase from Tim? and how much are they going for? i hope they dont make chinese copied like they did with the 255l
Oh and last of all.... is it louder than the 255l

Never mind, i found some http://www.ebay.com....=item20bf0c5a3a

holy mother of god

if i even thought of pushing my block the far it'd aircondition itself

Kyle - He's only running low boost coz it maxed out lol

[Evo-00x]

Mikey, most tuners place an 80-85% limit on injector duty cycle when tuning and my 880's got there just before 300kw atw.
I wouldnt consider 26psi on 98 octane fuel 'low boost', as its up there near the limit you'd want to take it on 98. Its not that uncommon to see some cars boosted to 30psi on 98 pump these days, but their CR's would be 8.5:1 and less. Also to run that much boost the fuel must be consistent, so no prizes in guessing that BP Ultimate is the fuel of choice for them too. You'd still want to carry a spare bottle of octance booster in the car just in case though

Awesome result Rob, you must be wrapt that it's starting to realise all your ambition for it.

You can get E85 in 20l drums that are sealed, there's not a real concern of it going off as long as you haven't popped the seal. I buy 2x 20l drums at a time and just leave them sealed until I'm ready to use them.

Great result Rob, good to finally see it make some power. Suprised to see your 880's maxing before 300kw i'm only running sard 800's and i'm just short of 340kw. I'd look straight to the walbro 400 intank over a 044 these days, When i had my III i only had the 255 intank and had to back it up with an 044 as it was just on maxing the 255. Just wanna see LOW 11's now mate

[Evo-00x]

Yeah the new design of the Walbro 400's look pretty good and the 400Lph shits on the 255 Ive currently got
They're only $200 too cheers guys.

[DOUGMO]

Good stuff Rob,the 400lph pump is definatly the go. I would probably go the 1250s if your tuner isn't happy pushing past 80-85% duty cycle.I'm sure it's great fun now mate

Cheers George. I want to stay away from an external pump and surge tank setup so the Walbro 400 sounds like the way to go.
Got a set of 1000cc Power Enterprise TL1000 injectors (Denso) from my brother Mikey today
They are these ones: http://www.velocityf...?idproduct=3637
I'll be ordering a set of adapter harnesses for them this week [rubs hands together]

Nice power!!

What turbo were you running?

[Evo-00x]

Its the GT3082 (GT3040) turbo with 0.82 rear. They use a GT35R compressor wheel, compressor cover and centre cartridge, but the rear turbine wheel and turbine housing are the same as a GT30 series turbo (GT3076 for eg). An equivalent turbo in the U.S would be the FP3065 which should have more info on them when being used on our engines.

The GT3082 sort of overlaps between the GT3076 and GT35R's, but doesnt have much of the benefits of either of them. ie. GT3076 is good for quicker spool, GT35R is good for top end.
However, the GT3082 turbos might not come on spool as quick as a GT3076, but they do flow more air and can make more power than a GT3076. They might not make as much power as a GT35R, but they do spool up a little bit quicker than the GT35R. It definitely overlaps into both territories, but only by a little amount and is therefore obsolete to continue making them in that combination I guess - it has no place in the Garrett line-up anymore due to people being able to step up from a GT3076 0.82 to the GT35R 0.64 nowadays. One thing that is undeniable though, is that the GTX3076 0.82 is pretty much what the GT3082 should have been - it has more overlap between the GT3076 0.82 and GT35R 0.64.

The way I interpret it is like the attached image. Both black lines are GT3076 and GT35R.
A. red line = GT3082
B. red line = GTX3076

Contradictory to what you read on the internet about the GT3082, its not easy to get these things to compressor surge on a 2L engine with a 0.82 rear housing. There has been no evidence of compressor surge at anytime on my setup, nor even at low rpm in 4th or 5th gears... not a peep.. even with the big 280 cams... and I dont even have an anti-surge housing on it!! The only reason we stopped tuning is due to reaching 80% injector duty cycle and needing some colder spark plugs. I assume you'd have to run these turbos on larger capacity engines flowing more volumes of air, or do something silly like put an 0.64 rear turbine housing on them to get them to surge? Yet even guys with 2.3 Evo's have run 10's with over 600hp with these turbos and have never experienced compressor surge, but others do... its a bit of a mixed result but I believe its due to whether or not you have an anti surge / ported shroud compressor cover fitted or not. A good example close to home of when compressor surge was evident was when BAZENG was running 24psi on a 4G64 2.4L with GT3082 and a 0.82 rear. He was only experiencing surge at low load at approx 2000-3000rpm in 4th gear generating approx 10psi boost. If he had stepped up to the 1.06 rear housing or fit a Garrett GT3082/GT35R anti-surge compressor cover on the turbo when fitting it to the 2.4L it would have shifted the compressor map to the left and never had experienced surge at all. Therefore in my opinion and real life experience, for a 2L engine to experience compressor surge with the GT3082 with 0.82 rear and a non anti-surge compressor cover, it would be more of an exception rather than the norm. And if it does, fitting an antisurge compressor cover would sort it out quicksmart.

Ok... who would like to see some pics at WSID from 19-02-2012???
Thanks to Cackling Pipes for these awesome images!!!

[MISGSR]

From my experiences I wouldn't want to be using 98 on over 250kw atw. (4) - now you have the 1000s = E85 time!!

So there's a 'new design' of the Walbro 400? I know the first version did the opposite of help to the 300 club...

[EVL20T]

Pics look good Rob you can see the colour alot better

Bad thing about E85 is that there is only 2 servos here in Newcastle that pump it

So its 98 for the time being until more becomes available

Just buy it in 20litre drums. It's not like you drive it everyday and need to fill up all the time.

[Evo-00x]

98 octane pump fuel for now Shayne With over 300kw atw it'll already be quick enough for what I want.
I can tell you right now that the stock GSR box in the coupe right now isnt going to like this engine on E85!!
Have to sort out the other gearbox first.

How about you put E85 in your engine, all that torque from your 2.3 stroker and 400kw atw through your gearbox.... then tell me what happens

Thanks for the info on the turbo mate!
