Gt35r Vs Garrett T04z - Discussion (just Post In This Thread To Create A Database)


Recommended Posts

My tuner (Ant Scali) has only just returned from Mt Buller.

He was working with Steve on the r35 development.

My car WILL be tuned Friday arvo.... then I will post up results as soon as possible.

26 with .84 T04Z

20 psi with little timing.

Just picked up the car, were doing some more mapping tonight. 4th gear pulls.

Doesn't feel to bad, mind you I have yet to have a proper drive of it.. Everytime I try to make a rationed opinion the adrenaline kicks in and I forget to keep an eye on how responsive it is.. lol..

Fix that boost control :D

If you can get it to pull to 21psi much sooner it'll be interesting to see what happens before/after.

So yes... that means get the graphs overlapped when you do :)

Funnily enough, almost a carbon copy of the one just above.

On a preliminary tune, it went 540rwhp (~400rwkw) at 19psi. Quite a bit lazier than the 35R though. On the same dyno, the 35R went 510rwhp on 26psi.

Am changing boost controller (as we weren't impressed with it's ability to hold boost) and tuning for 25psi next week. When that's done we'll print out a graph overlapping the 35R run with the T04Z run and I'll post it up.

Sweet, sounds good, what boost controller did u have in it.

ya didnt think the Z could defy human nature with response. but will be interesting to see the true outcome and how fare apart they are.

Yeh at this stage it looks like it's going to be about 500rpm difference, but I believe the area under the curve will be greater with the Z.

I had a Greddy Profec B II, and I've just ordered a Blitz Dual SBC Spec-R.

Nar, overlapped Scatalotto's. His tromped mine everywhere, but we'll see how it goes with the new boost controller and some cam timing adjustments.

Did Paul tune your car? Is that the Twin scroll or just a single entry? Have to let me know how responsive it is etc

I've had fairly good results using the GT35...

Thinking of going to a GT37 or GT40 when i do a 3L bottom end...

car wasn't running it's best on the day of the dyno either...

Ok, mine went 580rwhp today.

Will pick it up and scan dyno sheet tomorrow.

Keen to see a comparison vs your gt35.

what boost to make 580rwhp?

How much longer (RPM) to reach full boost than gt35?

    • Old Son, did you re-use the Holden ABS in the new shell or try a different module?
    • Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.
    • Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up
    • Does anyone know ow what these two plugs are for and if they should be unplugged? Just put the dash back together and can't remember if these were plugged in before or unplugged! (Blue and white plugs) 🤦🏽‍♂️
    • Did some FASTing ...got the impression that the actual part# was a moot point ; seems all of these hardlines for coolant are discontinued/NLA... like, I take it you're after the hardline that bolts onto to the manifold...that's NLA according to amayama & nengun .... ...just to clear up some confusion, they typically mounted the AAC valve to the intake manifold somewhere near a coolant passage, so the body of the valve heats up & holds it open when engine's up to temp - no coolant flows through the valve, it's a mechanical, thermal connection.
