We got it! Finally they were able to break through the issues with closures and limp mode. We got a full clean pull at 14psi and at 20psi. These are just baseline runs and we still have more psi and more timing to go for numbers. I can tell you it's making 550 tq before 4krpm which means this setup is going to be perfect. The twinscroll EFR 9280 comes on way sooner than everyone expected and I'm very happy with the result so far. Part of this is because of the 4" downpipe, external gate manifold design, and properly sized a/r housing.

Stay tuned today for power runs and to find out where the stock fuel system can go just on 100 octane. No meth, no nitrous.

Sound up and enjoy!

any updates?

Yes and sorry for the delay but I have been working non-stop on the car since Thursday. So these are the new modifications:

Turbosmart Eboost2
Tial 50mm BOV
Snow Performance Stage 3 kit
Deutsch Connectors for all wiring
Kooks Catback Exhaust System

We were having an issue with the previous boost controller regulating boost so I ended up getting the Eboost2 and it works great now. When moving to external gates and large turbo we may end up with a situation where the OEM system isn't able to let off excess boost when the throttle is closed so we added a external BOV for safety since we removed 1 of the ways it regulates this.

My last dyno pull it had low fuel and got the same code you did so we called it that night and I drove it home Saturday to wire up everything and install the Snow and EBC in the glovebox and have it look really nice. I spent my time just making sure all the wiring was very clean.

I removed my windshield washer reservoir and measured the capacity against the tank that the Snow kit comes with and the OEM is much larger and tucked away nicely. The OEM tank held a full gallon so I tapped it for 3/8" NPT and installed my meth bung in there and re-installed it. It came out really clean and ran my meth lines so you can barely see them. I installed the pump under the passenger side panel near the windshield so that's hidden too. Now I can just pop the hood and refill right there on the passenger side.

I drove the car to work today and am dropping it back off at CES Motorsports to go for bigger numbers. Basically everything on the car is now 100% ready for John to continue working on the dyno sessions with the guys at Pureboost and MHD.

I should have some good updates Tom as he has scheduled time then to just work on dyno pulls. I think she has over 65 pulls on the dyno so far. Haha

nice
keep them coming

thanks

nice
keep them coming

thanks

606whp and 642ft-lbs but the meth kit came with nozzles that were too small. New ones on the way tomorrow.

I will probably end up doing a MS109 tune to see the full capability. The 100 octane is just available at a pump near my house so that's what my daily driver tune will be on.

Congratulations @Dreihundert !!

 

[geert.bieseman]

Great gains indeed.
Now curious how the gains are on standard 93 octane.

 

[A70TTR]

wow, those are def great numbers.

Pump Gas 93oct numbers on our EFR9280 Supra....... 550whp on mustang dyno equates to about 615-620whp on a dynojet.

Running so nice numbers here keep up the good work.​

I just came across this article/video. It's not clear how much horsepower and torque this guy's MKV is pushing (I skipped the 370Z section of the video and went straight to the MKV section so maybe he said something I missed) but this is curious to me: just how strong are the MKV's rear axles and just how strong is its stock rear differential?

Even the 200mm MKIV diff and TT Automatic axles are known to be very stout out of the box aside from the limitations of the stock open diff and stock Torsen T-1 diff.

He says he replaced the rear axles with stronger ones on his MKV prior to his diff blowing out. Perhaps the diff casing itself is plenty strong but it's the differential itself that needs to be changed out for an aftermarket clutch type unit?

This second video only discusses the MKV's rear diff failure (following his drag launch under who knows how much boost) for the first five minutes.
