good stuff. post up the graph?

[johnbarry88]

this isnt the one stu did is it?

[cefiro]

Nice one, getting some turbos soon and will hopefully get close to the 300rwkw mark. Have you thought about getting some cam gears

[Andy D]

Thought about cam gears, but I like the fat low-mid range and am not really chasing peak power. Not sure if they'd make much difference for what I'm after.

Yeah, it was Stu (and friend) who installed all the parts, and did the tune.

He did an awesome job, and is a top bloke as well. I couldn't thank him enough.

[johnbarry88]

yeah stu does all my work he built my motor too..

[Stinky Rooster]

LOL @ gympie diesel. Not what you expect to see on a dyno sheet

Nice work though.

[Andy D]

it does the job.

unfortunately we're not exactly blessed with a choice of 4wd dynos on the Sunny Coast.

Hey Guys,

i got my 260 tuned the other day after running it in after the rebuild.

Basics of the work, full forged internals, sump and rocker baffles, oil restrictor, Sard Injectors, malpassi fuel reg, in tank walbro feeding 2 litre swirl tank then to 044 bosch external, Garrett 2860rs-5 turbos, ems 8860 computer running 20psi it made 420rwhp (313rwkw)

Need to get a set of splitfires to increase the spark then we'll wind it up to 22psi and hopefully reach mid 320's at the wheels, that way completely ensuring it has 300awkw.

congrats on your newly acquired power. How much did you spent on total?

I was planning on the same mod myself but i have to scrap it cos im being restationed overseas. Will have to wait till i get back in oz.

How does the Jim berry's clutch feel? Any hard slamming like a sledge hammer?

[Andy D]

Very nice work Grim. How did you manage the rwkw figure? (front driveshaft out?)

Jim Berry clutch is a rebuilt factory item. Slightly shorter travel than standard but really smooth (wife can easily drive it).

[cefiro]

cam gears can be set up to increase your mid range depending on how they have been dialed in. So if you ever do 100k service then great to do.

[BoostedBarge]

Nice work guys. It inspires me to begin the mods to mine

How do you find the GT-SSs? Not too laggy?

From my knowledge, the GTSS is just right for it. Probably you are refering to the GTRS. That will be too laggy.

[BoostedBarge]

Yeah I know the GTRS is laggy as all hell, but the GT-SSs are still going to be slightly laggy. I was wondering how they compare with stock turbos. I really wouldn't want much more lag than stock. The stockers can support another power for what I would want, it's just a shame the turbine wheels are ceramic, otherwise I'd keep them.

[GRIM_R32]

Hey Andy,

Yeah dropped the front shaft and pulled the fuses then ran it in rwd as my tuner only has a rwd dyno, waiting to sort a few things then will drop it back into 4wd, i must say, 313kw in rear wheel drive is ALOT of fun though, the "wow did you see that volvo go sideways" looks i get are pure GOLD!

Mine with the 2860rs's isnt too laggy, real boost starts to come on by 3500rpm, then acheives full boost by around 4200rpm, so it comes on fairly hard. Its even more fun when it hits peak torque around 6000rpm and breaks traction in all but 5th gear! lol!

[Andy D]

GT-SS's feel like they spool up just as fast as the stockers. Don't have exact rpm numbers, but by seat of the pants they are very impressive. Almost feels like a big cube NA motor.

My old RB20 with 450hp bb turbo, had lag. These are light years ahead.

Do miss the sudden boost hit and manic wheel spin though, (damn ATESSA, sometimes i wish i had a switch to turn that off)

[msports180]

Hmm been reading this with interest as i went for the 2860-7's as i wanted the response (there the same as GT-SS??). I wanted 300rwkw with them, might get it. Mine's a built motor with cams, so hopefully be responsive. Will know shortly.
