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?
