Well the internal gate 20g sucked balls last night. Well it did perform well except it was running 21psi minimum. This on 98 octane, We got it up to around 280kw.

We tried everything to back the boost down, even had the wastegate flap off and was lazy onto boost but then ran 21psi after 5000.

Ill post sheet up later

Its not blakes old turbo.

Roy at 4750 there is a missfire, i have fitted splitfires which sorted the constant miss, and a few other things but there is a miss at 4750 everytime.

The dyno rpm scale isnt perfect guys. Working off roller speed

I had barely any preload on my last td05h18g and I got full boost 19psi by 4200rpm on a sr but now got another one on the same engine but preloaded it about 3mm 3 complete turns in and now it makes 20psi by 4000rpm

Only difference now is its running eflex e85 where as it was running bp98 before

So not sure if preloading the wastegate tighter made the 200rpm boost response better or the fuel

Ah, k.

Did you try increase the spark dwell?

No i didnt. Car will be back monday night. Worked on ur car, ill try it on the rb25 tomorrow. Only 1 trouble area at 5000.

He is going to weld a new dump to the turbo, the stock setup even with the die grinded outlet sucks balls.

ah me clutch fail!

Did you get a graph anyway?

On the news on poncams for my car, someone has a spare set lying around who I'm going to do some deals with so will have new results soonish :whistling:

Hey Simon how does your old T04Z GTR compare with ur current T67 GTst in terms of rolling runs on the street, take -off and seat of the pants whack?? Much in it?

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

    • If you have a RB25DET NEO AWD motor, you will need this: https://www.hioctanedirect.com/ASR-RB26-RWD-Street-Comp-6.5L-Sump-Suit-R32/33/34-and-VL It is made for the AWD motor, but makes it fit a RWD setup and gives you a new pickup. Just one thing, the pickup sits quite forward, compared to a conventional RB25DET RWD motor. This may or may not have contributed to my previous AWD -> RWD shitting the bed at the track.
    • My car is also flex tuned. It's worth mentioning it (the LS1 ECU) has a 1D table for E85 addition and just uses the ethanol stoich part as the second point of reference. It also as a 3D timing map for Ethanol adjustment. You would think this isn't enough but it works pretty damn well. That said, I wouldn't want it in turbo application. It's like lifting non-natty, or taking meth. It gets you unrealistic results that break down more things going forward. If people used it to make the same amount of power they do on 98 then it'd be one thing. But people use it, crank it up to eleventy million PSI, it doesn't knock - but it pushes the point of failure to another, more expensive thing to break. Every time I see someone make 280kw on 98 and 350kw on E85 on the same equipment I just cry a bit and really wish they would just stay on 98 in that exact scenario. It's bad for you. 
    • This is kind of what I was thinking but the temp sender wire and the two pressure switch wires run through the starter subharnes and I eliminated the two pressure switch wires completely.  @GTSBoy I have a can gauge with unusually bright warnings should the oil pressure fall so the factory light isn't needed. I need to dig out my wiring diagram and see if I can sort this out.
    • It's a valid point. And it is doable with the Nistune. But I'm not inclined to flex it the way Nistune does - certainly not on a Neo ECU. They're already pernickety enough to tune just one one fuel. And of course, I'm not that interested in putting in a Link or similar, on a daily. With the stock ECU, stock looking turbo, etc etc, I still stand a chance of surviving a run-in with the plod. Last time it went over the pits (which was for the transplant, for because of a run-in with the plod), the Nistuned ECU did not even raise an eyebrow. They want to see a stock ECU running the engine, and they are happy to see it do so without the check engine light** on. Never mind that the Nistune is necessary to make the stock ECU work in a different chassis without ABS, TCS, etc. **And they actually provoke the CEL to come on by disconnecting the AFM, to prove that the globe hasn't been pulled!
    • This is why you flex fuel it...
