Puffwagon's Territory Adventures

[Puffwagon]

Intake manifold is on, AC compressor fitted, injectors and fuel rail fitted, wiring done, converter done up, intercooler piping sorted, exhaust fitted with a small join needing to be done tomorrow, adjusted the tune to suit the new setup and that's about it.

 

I can't find my wastegate clamp so no doubt that will be the one thing to stop it in its tracks. So yeah I should finish it off tomorrow and then spend the rest of the week finding my clamp.

Not a massive amount done today, exhaust fitted, dump connector made, hotside fully assembled, check wg spring @12psi, ran the oil line to the turbo to give it a quick fire up and after reverting a few throttle settings it starts and idles now. Maybe tomorrow will see it fully assembled and on the road.

Ok it's all back together and I've gone for a drive. Something is up with the tune cos there's a couple of issues. I'll sort it out and update when it's all good.

Ok another small update, I had to change the tune for the 4 bar boost sensor, as it still had stock values. I put it into open loop boost control for now, cos it has a 4 port boost control solenoid and it was making too much boost in closed loop. Fortunately I had anticipated this and updated the ignition map to account for it before driving.

 

So for now it is running on gate pressure which is 12psi, it creeps up to 12.7psi up top which is fine. It comes on boost as quick as an FG turbo, miles quicker than it did before and obviously outflows the stock setup considerably on the hot side.

 

Also despite several recharges, the battery is farked. I'll replace the battery tomorrow and do something with the boost control when I get a chance. I'm looking forward to seeing how it goes with 20+ psi up it's guts, should be pretty decent

Nice man.

So with my G35-900, I started with the 1.01 housing, then went up to the 1.21. It came on way earlier and made heaps more power with the 1.21. Open vband housing, but I still think your split housing is too small. Barras need exhaust flow

[Puffwagon]

The current housing is bigger than a stock housing by a fair margin. You can max out a gen2 gtx3582r with a factory T3 housing, I've gone slightly bigger, explain why I should go bigger again.

 

I posted a picture of the housings side by side, go back and have a look.

Cool mate, good luck with it 🙂

Do you know a good tuna?

Funny you should ask... The tune was giving me the sh*ts so I reverted it to stock and just added the necessary things, such as injector data etc. After a bit of messing around I've got it to 323awkw at 15.7psi with stock timing, so there is probably another 20kw on the table just with timing. I'll leave it as is for now cos it has 13% ethanol in the tank, and that makes a surprising difference to how much timing you can run.

 

I've got the 4 port working again in closed loop and it is controlling the boost like it should be. I'll start winding it up shortly, just gotta do the fuel pump pot swap and it'll be sorted.
