congrats

Baby update:

Adjusting sensitivity in Eboost2 fixed the boost taper through RPM. Just need to finalize boost tip in before meth hits and tune is pretty close to dialed. 18* timing and 12.5# is a fun ride.

May upgrade to a 4" mid pipe to dual 3" Y as close to the DP as possible to try to free up some backpressure. But I'll enjoy for awhile first.

I forgot if you said it before, what fuel are you running? Any dragy 60-130 times?

GN_Drake · 10-25-2021, 09:25 PM

Lt4 high and low side plus aux pump.
+30 injectors.
+32 cam.
Meth.

I've done 40-110 on draggy, but not 60-130. Mexico is far away...

I doubt it will be as fast as Kevin Martins SS single turbo built by GPI but I think your gonna have a fast SS. Kevin just broke the Gen6 Camaro record with an 8.35@160 plus and that had been held by Mike Swanson for 2 years so GPI has done some killer cars for its customers. I think your in good hands.

Agree, it's not on that planet. It's only pushing 12# and 13# on shifts. So it's not going full send by any means. If I found a way to fit a full 4" dp, then it would have alot more steam to work with. I think the 4" mid pipe will get me as far as I want to take a street car.

Love me some turbos and glad to see more guys diving into the pool and making it happen. Good luck on a cool build.

Ok, so I have been battling this meth coming on late during boost tip in... I got ahold of nitrous express, and only way for them to diagnose the Snow setup, is for me to send them the gauge/controller. Regardless, didnt seem safe because some logs showed over .9 lambda for 3-5sec before it brought fueling back to within spec of commanded. You can see one example of this in the first picture with e77. There are worse examples, but this is the most recent log handy.

Second picture is with base tune from GPI to see how far we can get without the meth on E50(and timing removed to get shake down runs). Right now its E55 and ~8.5#. Really wanting to get at least 12# when all said and done... but the ms is creeping to 5 pretty quick by ~9#. Ill get it closer to e45-50 as i drive it a little more. I might add the meth back with 50/50 mix if they can find the issue, just to spray a small amount to keep IAT's down come Texas summer heat. This is TBD though.

Posting more for sharing the data and the issue I found with Snow Stage 2.5 system. Has anyone seen similar issues on that system?

Reiterate fuel setup:
LT4 HPFP
+30 injectors
LT4 low side
Aux low side
+32 GPI turbo cam

Ben is back in office Monday, so hoping we can get this tune dialed in a little more to get boost back up. Completely different car at 12# vs 9#. Not asking for moon boost, but hitting 13 without meth would be nice

Why did you go snow vs alky control?

No reason in particular. Gauge setup is easier than the two modules the Alkycontrol comes with. I have Alkycontrol on my GN and worked flawlessly for a decade plus.

Regret that decision now... Maybe I got a lemon, who knows

SSUNDVL · 11-07-2021, 02:56 PM

Yeah when I saw the 85 GN in your sig it really had me questioning the alky vs snow. Hope it works out.

If things don't work out and you do decide to go alky, the gauge situation is pretty easy on the 6th get especially if you re-use the windshield washer res, you can route everything under the passenger side footwell and mount the PAC there, then run the wires under the dash and velcro'ing the controller next to the kneepad makes it super accessible. Lights can also be routed very easily behind the steering wheel so they are visible yet out of the way.

GN_Drake · 11-08-2021, 12:18 PM

Had a solid run while scanning the no meth tunes. Custom 40-110mph due to Mexico not being long enough of a strip. This in only at 10.5#.

Should have enough to get to 12# on e50 once we have a chance to work the tune updates I think. Def feeling strong now.

GN_Drake · 12-05-2021, 09:22 PM

Driver mod needed....
First fill pull from dig in Mexico. Had to shut it down early for safety.

KingLT1 · 12-06-2021, 09:23 AM

Definitely need me behind the wheel.
