This here is my unopened rb25. Has a surge tank,

044 pump, 750bosch injectors, e85 fuel and an apexi

Power fc. Turbo is a hks 3037 .63 rear housing with a

Garrett front cover. Tuned by smmotorsports making

344.1rwkw on only 15.8 psi. Since October last year

I've done 5 drift events, Phillip island sprints and

Winton Vic time attack over Easter. Engine still has

no signs Of wear.

Hmmmm interesting, my car has tested the limits of that turbo in every way and with a 0.82 rear on the same turbo with every supporting mod possible the best we ran was a 320-330kw...... 344 required 20psi bleeding to 18 and that is with the bigger rear housing!

yeah, I think we can conclude it's a happy dyno, however it's definatley a 300+ car and would be an assload of fun

Yep not doubting that part! It is an awesome combo and tried and tested many times! Good result and welcome to the club haha

Good to have people around who are willing to try and test combos so you know what works :D Your car has become a bit of a benchmark for the GT3076R's ability, I reckon!

Well we have found the limit with this combo and will be looking to improve where possible, the 3076 and RB25 were made for each other :yes:

:ph34r: swap it for Hypergears VNT and get 400kw.. do it!! :yes:

Not convinced on that as yet! Good result for sure but there are other ways to make power on mid frame turbos! You should know, you are about to try ;)

srsly?

it's written on the chart :P

:laugh:

I know i'm probably going to be shot down in a ball of flames for this.... but is there any real point in shooting for 400?

surely it's just useless power unless you have a very very good and expensive setup

@ 320+ rwkw in a 1.4 tonne chassis I needed to run NT05's just to have a hope of traction, and on your average tyres it was already game over.

seems to me like it's just inviting the motor to pop for power that you will never use beyond a dick measuring contest

No need for flames, it is a pretty decent comment and something i have also said in regards to my car... My tuner was saying i should go to the 35r frame turbos but i said i was overall happy with the performance....

Overall i think mine needs a little extra spool and maybe more in the top end for drag and long open circuits.... For street and hill climbs i would be running gate pressure anyway so it gives you all options.

My car is only running RSR 265's but once warm i can start to get them to grip up, of course i cant launch the car on them but that is where MT tyres will come into play!

As an all round car to do all events i dont see boost settings allowing 330kw, 360kw and 390kw to be a problem as you cover all bases and still have a damn fast car!

Of course bragging rights too :P You know, coz racecar!

I would love to have more because i can! But the old 3037 has nothing more to give! I will continue to seach for a better way haha

Finally some results. Slap us with a teaser.

Haha yeah some results for you finally! And it went over 500rwhp as planned ;)

Well the meth injection is finally installed after months and months.

Was hoping to join the club but might fall a little short of 300 :(

Looks like the old 2835 pro s is maxing out and we have had to tune to fight off knock rather than outright power.

Back up to JEZ tonight to finish the tune and try a couple of things (cam gear adjustment, adjust afr etc)

You never know, I may get there buy I am a little doubtful.

Ah damn! Well i hope it goes well! Shame i hadnt picked mine up from its tune today or i would have popped in and said G'day!

I stay in this club with 390kw :woot:

    • It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪
    • And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil
    • Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.

    • Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
