that is very laggy imo

it looks like Roys RB20 graph with a few more pony's up top

waiting for results with NVCS working

edit - that sounded a little harsh, 300rwkws from an L2 is great, but full boost at 5000rpm is not lol

My 30DET is now running TDO6H 25G, budget build with Hybrid manifold and 50mm Turbosmart gate. Turbine is the 11 blade option with 12cm housing. Tighe camshafts correctly dialled. Track car, chasin

LOL, too many results with no VCT :(

Interesting to note that the RB25, even with its extra displacement and half a point of compression doesn't really spool the TD06-20G 10cm as well as an RB20 running an 8cm housing. Will be interesting the difference the VCT makes. Would love to see the engine tuned on 98 instead of corn fuel, but if you have access to E85 and car is tuned for it understand why you wouldn't bother with 98.

I don't expect tuning along with E85 can see the result go from 17psi at 4,500rpm to the 21 psi at 4,000rpm of my graph above?!?! Then again I dont know dyno tricks 101 so perhaps there is something different to how the cars were loaded/run on the dyno. But my thing with no EBC and a simple but effective bleed valve which was holes in a bit of fuel line to bleed pressure gave me 21psi at 4,000rpm. Seems both engines are making ~130rwkws at 4,000rpm so the turbo isnt working as hard as you would expect at 4,000rpm on the RB25.

The above graph was not on my tuners dyno, and it was a comparo against one of the tuners cars other setups so it is at least a fair comparison to the other curve which was an RB20 running a HKS GT-RS.

Maybe the 10cm housing it a tad too big for the 20G compressor as the curve seems to have the BIG turbo shape of still climbing at the rev limit vs the bell curve look I would have expected of a 20G on an RB25.

Found it finally

yeah it should get close, was told it had a new clutch..big words like heavy duty and ceramic were used...

looks like they were just that... words :/

I hate the screamer already, when it first cracked I thought WTF!!!...some more work for you Scotty..lol

Thin red line is my old turbo, I have lost a little down low but it doesnt really feel any slower ..power ramps up so much nicer..

It Did hit 276kw at one point, holds boost nice too

Im just happy I can drive it again and as long as I dont mash the pedal too hard the clutch holds up ok :D

so got a reply back from them on ebay:

It still works as there is high % of Inconel.

If there is smoke, and then you need to start take care of this issue.

Gonna push for a replacement cause im not really interested in putting a timebomb back on...

All suppliers will cover their backside first, regardless of if they will warranty the issue or not.

You should ask him if the turbo gave up next week would he replace it then? And if the motor injested parts of smashed turbine wheel will he also warranty that?

Just point out there is a reasonaby high risk and the cracks were not there from new. That means they will only continue to spread.

Having worked with the person before I know he will accept the warranty claim after you make a large enough fuss about it.

Yeh, between United and Caltex it will be pretty easy for me to run E85 now. I am still going to just use Datalogit to switch back to ULP for daily duties and making sure I dont have E85 just sitting around in the tank and lines when I am away with work etc.

So can someone start to explain the difference between Artz's RB5-20G result and DVS JEZ's? Surely VCT and tweaking a tune doesnt make 1,000rpm difference in response???? I ask because I have read that on some setups E85 can make a setup spool a little slower....have not seen any cases of it yet and wondering if its a factor in this case

yeah I got no idea, i dont quite understand VCT well enough to know how much difference it should make but it does seem a bit too much..

Jez is also top mount, which usually will helps spool a little earlier doesnt it...

You said that twice in the same post... You drunk? Lol.

I don't see how top mount would help response? Unless the manifold is a restriction, and as I was told in the other thread in no uncertain terms, the stock manifold is not a restriction at these sorts of power levels. So I can't see top mount being of any benefit performance wise.

Jez is fairly conservative when it comes to his tunes in general, leaving a big safety margin. I would say his is just not finished yet and is still in its build stages, once VCT is in and hes able to ramp boost on harder Im sure the results will reflect its completed state.

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
