Long time customer decided it was time to turn up his combo, ran out of fuel pump, upgraded the fuel system and made a smidge more chooch. Keep an eye out for this unit at local street race events this summer 👀.

Haven’t shared anything in awhile, still cranking out customer work. I’ve been at capacity for awhile, just a reminder - tuning is 3-4wks out unless you’re an existing customer needing minimal tweaks. I am not taking on any builds until this fall. If you have something in mind, I’d suggest you get in touch soon so we can schedule it and make a game plan. Spots fill up quickly.

Now onto the cool stuff - Beautiful 1955 delivery that came in for tuning and diag. 525hp LS3/4l70 combo.

LS swapped Pontiac Solstice - Came in for a 4L60e swap. Bubba Ginn 60e/Converter combo. custom drive shaft from Tim Herr . 3D printed a filler plate for the console to clean up the old manual shifter location and added a line lock.

What are the odds this is the only Solstice sporting a Motion Raceworks Operator shifter? 😂

Still alive and kickin’, just head down and trying to get caught up.

A local racer dropped off his small tire new edge mustang for some work - Installed an Innovators West Belt driven timing setup, engine plate,crank driven Procharger combo, fabricated a 4” aluminum charge pipe, and added a funny car containment to the 8.50 cage.

Photo of the old procharger setup included for a before & after.

Keep an eye out for this dude triggering win lights this season.
