Awesome. I love the lights (and everything else). Too bad they aren't available!

Re: 14' forged 426 turbo

Update time. The 426 turbo is now running. New CFR hood installed. Verona 10.5 X 22 wheels and 305/35/22 tires at all 4 corners. On 91 pump gas at 14 lbs making 772 rwhp and 846 ft-lbs torque. No EVIC numbers yet for several reasons, including the fact that she scares the shit out of me New problem.... The 76mm turbo is maxed out at 14lbs. Cant get a pound more out of it, which is severely limiting my ability to do the 104 octane, 18-20lb boost tune. For this, Im replacing the 76mm turbo with an 88mm turbo next week and will see if I can actually get 4 digits at the rear wheel Now, it pulls like a freight train and sounds like hells symphony rolling, but the TCM is now schizophrenic and doing weird stuff under boost. Will be talking to some people about addressing this issue. Anyhow, here are some pics. Pardon the dust. I had just driven it back 100 miles from the shop in West Texas and you could plant a flower garden in the hood :/

Re: 14' forged 426 turbo

Keep us posted on what you do with the TCM. I'm curious if anyone can truly tune it separately from the rest.

This is only video so far. Friend of mine that races for TSC was trying different launch functions but we only had a limited area, so can't really appreciate the boost kicking in. Was hoping to get it to the track for some runs tonight but the snow is coming in at 8 :/

Re: 14' forged 426 turbo

You may want to look into checking out your wastegate spring pressure and boost controller.. I would think that turbo has more in it..

Re: 14' forged 426 turbo

So, another update:
1) Overheating issue was related to aftermarket overflow basin that was about the size of a paint can, allowing for loss of coolant and slow air accumulation - fixed with replacing with OEM overflow basin.
2) 76mm turbo swapped for 88mm turbo and wastegate moved from pre-cat area to first turn of outflow pipe and springs increased to 14lbs - manifold pressures more adjustable and Innovate boost controller now playing well with everything else in the sandbox
3) First dyno report pretty much the same for pump gas (shown earlier). 104 octane tune completed yesterday (will post pic of sheet later) now has max HP at 1060 and torque at 1010 (Mustang Dyno at 3600ft)

Heading to pick her up this afternoon (hopefully), get my tune files on comp, get her home and cleaned up and pics posted soon. Working closely in the field with some guys who are working to crack the tuning on transmission and will keep you guys posted. Next up is custom fab CF driveshafts and half-shafts

Simply amazing, 1000+whp.... And I can't get my 2015 pcm tuned still. Congrats on an epic build!
