Hi, does anyone have a dyno sheet or log of a GTX3584RS gen2 on a N54 engine? Thinking about testing one on my Speedtech Kit with A/R ~1.0 T4

Greetings

Martymil, sorry to change the subject, but did you see a noticeable power increase when you changed to mhd only?

We haven't maxed out the tune on the car with MHD as I blew the motor at just over 500rwkw before Xmas, switching back to logs on E85. I suspect we'd have got closer to its potential with MHD and its just a nicer drive all round.

We had endless nights having to tune the car over and over with JB4 and changes in atmospheric conditions. You'd get it sweet after a dozen runs or more fiddling about until we could get a clean log. No such trouble with MHD and a custom V8Bait tune. Head out to our logging road, a good 45min drive, and with heat already in the Trofeo R's, peddle to the floor. 2-3 logs and all the data needed for any changes.

3584 is available in many different configurations. If you are serious about getting one, drop us an email. We can get it any way you want most likely the same or next day.

In the new logs which are buried somewhere in the files it reaches 20 psi by 4200rpm that is not bad for a massive turbo on a small capacity 3L engine, really it's to big unless you want to run 35psi plus which was intended but never reached as the motor let go

at which Rpm do you see 30 Psi with the Garrett? I have been using a Turbobandit TB70 70mm with 1.15 a/r so far with my speedtech kit. Pretty laggy too. Highest i hit was 36.5 Psi with ~8* timing on my stock engine. On the other hand traction is nice with torque so late in the powerband. Thought the GTX3584 is spooling a bit better but also keeps boost in high rpm.
