In case you missed the Iron City car show this weekend with Pittsburgh Brewing Company & Max Motive, here is a little recap of what we had going on. We’ve been lucky to be a part of this show for all three years and are excited to get back to work on some new projects for next year! As the event keeps growing, we are more and more impressed with the turnout, variety of vehicles and vendors each year! Thank you for all that we’re involved!!

A little 2650 action to wake this spotless C7 Z06 up! Not only does Dylan's Coatings take meticulous care of this car, but drives the crap out of it as well. Shooting for a high 8 second pass when weather permits!!! Texas Speed & Performance American Racing Headers DSX Tuning Wisher Performance

After a long list of previous modifications, this client was ready to go all out with the addition of a Kong Performance supercharger, ported blower, Grip Tech 2.30, Cordes Performance Ice tank & an upgraded heat exchanger system along with some magic on the keys from MSTuning. We were able to lay down 968 whp! This is going to be one bad m**o on the street!

Not every day you get to throw a 70 Cuda on the Mainline DynoLog Dynamometers. We were able to pick up 49 hp with changing nothing but some screws and timing. Gotta love a good old carburetor set up from Holley!!
