Good deal, hope to see some good numbers

[Goertz]

Dyno tomorrow. Just putting some good miles on it and street testing today.

Got my first free oil change from chevy and they about crapped themselves seeing the car.

For some reason car was running super rich yesterday so i bumped the boost up till it leaned down (bumped it to 8psi and it was holding ars at 12.5). I guess it just needed the piss driven out of it cause it is running back where it is supposed to be today so boost is back down again. With some luck though we still have a little room in the 100% stock fuel system and can get good ars at 8-9ish psi.

the prototype is 100% finalized with a oiling system and everything to make us happy.

Get those dyno numbers up really soon (tomorrow we should), then next weekend rip it all apart and build fixtures and get geared up for production to begin in September

What's that noise toward the end of the video?

Maybe it's just me, but does 12.5:1 AFR seem a bit lean to anyone else, too? I'm shooting from the hip, and it probably doesn't make much difference, but how come you're not aiming for something in the high 11s range? Granted, I know more about big power from 2.0L 4s running E85; I'm just curious is all...

[V8SS]

wow this came together so fast, congrats and best of luck... Looking forward to dyno numbers

[Goertz]

On a typical port injection in the intake manifold 11-11.5 ars are the norm however on a direct inject engine they run a little leaner 12.5-12.8 ars.

6psi of boost and windows down lol the rear mount you can realllly hear the turbo boost. Sounds like air compressor exploded

[Goertz]

Minor things still to change for final build

Nicer vent to atmosphere catch can that will mount where factory air/oil separator mounts on passenger side head.

Billet Oil Cap

Full braided stainless oil feed and return lines made from our local hydraulic line company.

Thin the heat sink fins down on our custom billet oil drain

Wastegate will be located closer to turbo and on the hot side of the piping. The vband was in the way and then the sub frame was, that's the reasoning for the wg fitment on the prototype.

Tighter radius 4" bend off the tb so will fit with factory intake manifold (the 6" radius bends has it just barely clearing the radiator right now, a 4 on 4 bend will clear much better and work perfectly with stock intake mani)


For the future I will be getting in contact with cnc mandrel bending companies to have the y pipe, exhaust, downpipe, charge pipes all cnc mandrel bent to reduce the amounts of welds and reduce build time. I will look into building a street legal (catted) y pipe.
Alternate sizes of y pipe, and exhaust and turbo to better match individuals needs
(ex: a Billet s366 turbo should hit full boost approx 750-1000rpm sooner while still being able to support 900whp)

Supplemental stand alone fuel system in the future

Stand alone oiling system utilizing 2 pumps and a sump tank for the turbo

Full Ceramic Coating and Professsional heat wrapping to reduce heat and decrease spool time

[Goertz]

Ohh when we pull the car apart coming next week (19th)

We will also pull the factory headers so I can pop a fixture and look into building a more efficient shorty header and fully heat wrapping it also. We believe we can still get full boost down about another 1000rpm by fully header wrapping the stock headers, y pipe and exhaust pipe, then turbo blanketing the turbine housing.

I pulled out my laser heat gun and checked temps after some hard pulls with it today.

Turbine housing 650-700F
Cold side aluminum charge pipe coming directly out of intercooler 100F
Billet Oil Drain adapter 220F
Oil cooler hot side 180F
Oil cooler cold side 140F

based on this video of does a turbo blanket work


I like to think we are seeing pretty decent egt at the turbo being that we are pretty much right on par with that of a typical top mount near engine turbo setup.
