i love my auto but I am having an existential crisis because no ptuning turbo for it Q.Q

Please reconsider making a kit for the auto owners.

We've had a handful of inquiries over the past few years for an automatic version. But due to the larger size of the A/T vs the M/T, It would require re-engineering a completely different overpipe, turbo placement, downpipe and all the other hotside components and brackets. At this time there's just not a real demand, as in 25+ kits, to justify the R&D on an A/T version.

Going to dyno tonight on both 91/101 octane tunes. Can't wait to see what kind of power I'm putting down at 14.5 PSI (101) on the 2867!

274/217 at 12.7 PSI on Evasive Motorsports Mustang Dyno

So that is what it will take for you to consider making one?

I'm sure we can get that easy.

I co-own a mechanical engineering company.
I would be willing to put an engineer on the project if you are interested in partnership. I am talking flow analysis and all the bells and whistles.
Send me a DM with contact info for further discussion please.

was that dyno pull with 91 or 101?
and are you running the gt or the gtx 2867r?

[BRZ_Willy]

His build thread says Garrett GTX2867R. Not sure of fuel though.

That pull was with 101 octane in the tank, running about 1 and 2/3rds degrees more timing over my 91 octane tune. I could have run another couple PSI to squeeze more power which the 101 tune was setup for, but I only got 3 pulls total at Evasive so I didn't get to do all that I wanted.

GTX2867R with 7lbs waste gate spring and 70 % duty cycle on the boost solenoid on that dyno pull.

[rb6freak]

Here is the 91/101 tune and pull overlay. I instructed the tech to do lower boost on the 91, but according to the chart he did the higher boost setting. I don't know though, I think maybe they mixed up the 3 charts. It's possible, but hard to believe 1.66 degrees more timing added that much power. The 91 octane tune is set to about 9psi where as the 101 I can do upwards of 14 (was 12.7 in the pulls on the dyno).

are you still happy with the switch from the 3076 to 2867?

[Xevuhtess7]

Why does it take all the way til 6400rpm to build peak boost?....

Yes, very. More so with all of the V2 upgrades and the fact that its easier for installation/maintenance with the smaller turbo.

My boost solenoid is very basic (AEM Tru Boost), at 1PSI its set to ramp up spool until 6PSI (my WasteGate configuration), and then maintains 70% duty cycle. My tuner said he could run circles around this setup if I plugged in the solenoid 5V/ground to the ECU so he could control it, but I already have my gauge cluster setup and I kind of like having the flexibility to adjust.

If I set the solenoid to a higher WG spring number or use stronger spring in my wastegate, I could achieve peak boost much sooner, but I like it this way. Also note this is a 4th gear pull on a dyno starting the pull at 3K.

Which oil cooler will fit with this kit ? I currently have the jackson racing oil cooler will that still work?? Also do you need injectors and pump for 94 gas???

I'm not sure which off-the-shelf air oil cooler kit works with this kit. I'm using a Setrab series 9 15row sandwiched between the intercooler and AC condenser, but it is bolted to the bottom plastic tray with a home brewed bracket further securing it to the AC condenser. I believe the JR oil cooler bolts to the bottom of the crash beam right? I'm not entirely sure that would work. The intercooler bolts to the crash beam and hangs underneath it. You could relocate it to the same location I have here.

See my oil cooler here in front of the condenser.



Injectors are highly recommended. A friend of mine tuned with pump gas on stock injectors and was at about 85% duty cycle on the port injectors and the tuner didn't want to take it any further because of this. So he ended up getting new injectors. I'd recommend that too.

Pump not needed until you're going far beyond 350whp.
