Hi guys

Currently running a gtx3076 .82 rear housing on my s2 r33 rb25, it's got a 50mm external gate aswell. What's the max power I can get out of this turbo? I'm making 305rwkw on 19 pound 98 octane tomei valve springs only otherwise it's unopened.

You're in a similar boat to me in that 98 will hold back the full potential of the GTX, good to hear you made 300+ though as I have a very similar set up to yours nearly ready to put together. Have yo

I was making 320kw with 16psi, each psi increase was giving a solid 10-12 kw's so if that kept up I think it would of easily smashed 400kw, however, Ive been told after a certain psi it would stop giving so freely,

if a gt3076 is rated at 520hp and has made 360kw, then a gtx should do 400kw you'd think.

Have you had a read of the WMI thread? If you don't have ethanol readily available it may be worth looking into...

no way it's going to make 480rwkw... i could see it at the fly tho... just

Those ratings will be crank hp estimates - and very rough really, going from the 64lb/min peak flow the compressor is rated to.

Never seen a GTX3076R "all in" yet, but I'd expect that it'll be possible to crack 400kw @ wheels on E85 on a good setup.

Glad to see newer members are making good use of the discussions we've had on this forum :)

Powertune have managed 400kw from a couple of SR's with GTX3076Rs. AFAIK their dyno is not super high reading or anything, its fairly well trusted.

That being said I would say there is definitely 400 in one on an RB25.

They also made over 370kw with a 3076 which we found physically impossible no matter how hard it was pushed! :P

I think 400kw is possible though, there is one in the 300kw club thread thingo at 384kw or something from memory!

have you seen their ramp rates? they're too short.. hence the numbers.. (just saying)

We've seen 370 from a 3076R a number of times on this forum, even 380 IIRC... Lith posted one which was a 52T, also up at that level.

There are often reasons beyond the turbo itself why some of us can get there and others can't.

John, I know the talk yet still believe the results are within reason. Not 20% variance or anything silly like that.

Fair enough.... Just a lot of interesting results there! And some interesting mishaps on mates cars....

A lot of those reasons come down to dyno. When talking dyno expectations on threads on SAU I am using a second language, I have to convert everything from what I am used to (Dynapacks with SAE correction running ~9s sweeps) to understand or suggest numbers on here. Even then not all DD dynos read the same for whatever reasons. It is clear to me that JEM's dyno reads much lower than I am used to - they have multiple 56T GT3076R results on strong setups which are maxed out under 500whp/373rwkw yet I've seen 56T GT3076Rs make that or more with more basic setups.

Supporting mods I have are a plazmaman plenum,044 intank,6 boost manifold, 740cc tomei injectors. Could possibly add another 044 pump and surge tank I have to the mix aswell. I have another turbo I might throw on later on down the track to push big numbers. I'm trying to avoid the e85 route as much as I can atm and stick to 98 :) The cars running really rich at this power level aswell

Trusted? They still have a broken air temp sensor?

Got pics of the setup? I like pics :D

You shouldnt need another 044 at your current power level!

      rb26, build year ? check my math

      By Butters · Posted

      I've never seen this on a factory built RB26 have the screws come out, or gears break for that fact. Only once someone has touched the motor have I heard / seen it.   I've seen a few factory built Rb25's shatter gears but we talking high mileage extreme beating at drift track, constant limiter for a full season.  Well outside what it was built for.

      By Butters · Posted

      Over the moon in fact.  Engine is coming out to put on a new enlarged sump. I planned on putting on either a new pump(Tomei / Nitto) or billet gears.   But a bit of waste of time if the crank has narrow collar.   Things spiral quickly, if crank is out, new bearings ... maybe new rods and pistons ... wait just rebuild the engine... oh but I should get an N1 block  .... 40k later  .... haha.

      I think he's just happy that the crank doesn't have to come out of the engine in order to have a good (read reliable) oil pump.

      Doesn't really do any good, especially without billet gears. The oem pump is crap. If it doesn't break, the screws holding the backing plate will come loose.

      Any help appreciated

      Has the VCT bulge on the intake(Actually, you can see the VCT solenoid on the intake side, so looks like an RB25, but thats not a RB26 intake for sure. Wouldn't be surprised if its a rb25 that someone has just 'slapped' on a turbo on the factory ecu. If its running like a dog, then the dead giveaway is the intake.. missing the AFM.
