Wiring Wednesday!!!
We broke down the OEM engine harness to extend the bulkhead for more clearance of the heat from the Garrett - Advancing Motion G35-1050. Cleaned up a few items with it as well.
We fitted the Injector Dynamics BPC100 in the most inconspiquous location, yet still serviceable, & easy access. Relocated the battery to the trunk, while building posts in the factory location for easy access as well.
We set up the Radium Engineering surge tank on the opposite side of the trunk to hold the 550lph Walbro Fuel Pumps all being controlled with a PnP Link ECU EMS.
Keep an eye out for the rest of this build. 💪

Tr**ny Tuesday!
This TR6060 came in for a refresh, with no complaints of any issues. Upon tear down, we found part of 6th gear laying in the bottom of the case. We performed our Stage 2 upgrade with carbon synchro's, new bearings, & bronze shift pads to get rid of the plastic units from the factory. Obviously we made sure to replace 6th gear, & its synchro sleeve as well.
This Camaro was headed for the road course, & be back in for some fuel upgrades before its next event. Stay tuned.

HEMI Hump Day!!!
This gorgeous '70 Plymouth Road Runner made its way in with a 392ci crate motor mated to a Tremec Transmissions TKX & wasn't running properly with the previous calibration. It was having some issues of excessively backfiring while decelling.
We did a baseline run, & could see it was running leaner than we'd prefer to.
We got the Modified by KC calibration dialed in via HP Tuners, & the byproduct was additional power as well.
We picked up an extra 31whp & 26wtq!💪
Vince is super pleased to get rid of the popping/backfiring while decelling, & no longer running lean

🟥 : Baseline : 416whp/448wtq
🟦 : MKC : 447whp/474wtq

Honda Hump Day!!!
This brand new Civic Type-R arrived with only 2700 miles on it to be outfitted with a 27WON Performance downpipe to a Private Label Mfg. front pipe to a Tomei Powered Inc. Expreme titanium catback. We mated up the Eventuri carbon charge pipe to the intake. Along with the carbon intake manifold from Drag Cartel Industries with a Spoon Co.Ltd. throttle body.
We dialed in the Modified by KC calibration via COBB Tuning AP3.

Throwback Thursday!
This minty 67 Fastback Mustang made its way in with a Gen2 Coyote swap done, & a Roush Performance supercharger attached to it.
It had some drivability issues, & we found that the builder had both of the primary O2 sensors on one set of the headers on the drivers side only. One in a single runner, & the passenger side in the collector. We moved it to the passenger side where it belongs, & moved the drivers side in the collector rather than the single runner where it belongs. Then we dialed the Modified by KC calibration in via HP Tuners

✅️ : MKC : 573whp/478wtq

Still continuing with more CTS-V's, this third gen made it's way in for a Stainless Works catback system.
We'll see it back for additional mods a little bit later on.
