Another 2010 SS Camaro we just did. This car came to us & had a previously installed, Airaid intake, camshaft (specs unknown) & a single disc stall converter. We weren't able to get horsepower numbers before we started because the car had been taken apart & wasn't running. We installed a ZL1 supercharger with an ADM performance 2.75 upper pulley, a ZL1 fuel pump, an ADM Performance fuel pressure control module, Rotofab cold air intake & ID 850 fuel injectors. It makes 620 (rwhp) horsepower on 91 octane through the 6 speed automatic transmission, very quick, fun & fast car!

Here is a car we did last week at the shop, it's a 2010 SS Camaro that came in with longtube headers & 3 inch exhaust, we put it on the dyno & it made 400 rwhp. We got right to work with all the new parts laid out & ready to go on after disassembly of the stock motor. We installed a Brian Tooley Racing stage 3 pd camshaft with supporting valve springs & accessories, to hold the cylinder heads down we installed ARP head studs. The big horsepower adder in this combo is a GM 1.9 LSA supercharger with a ZL1 lid on top, we installed our 2.7 upper pulley with quick change hub, a Rotofab cold air intake & ID 850 fuel injectors. This combo needs a fuel system upgrade so we dropped the rear sub frame & fuel tank to install a ZL1 fuel pump along with a ADM fuel pressure control module. We then got to work doing the custom dyno tune to make it all work together. The end result was 670 rear wheel horsepower! This car gets over 22 mpg on the freeway, sounds awesome at idle & drives great! The only problem is the price of rear tires because the owner is going to go through them fast with a big smile on his face. Thanks to the owner for trusting us with his baby!

We really appreciate all the support our shop has been getting since we opened! Makes us feel really good & that we must be doing something right! This customer called & said I'm 20 minutes away from your shop with my 2014 ZL1 to drop it off, I've seen & heard about your work & I want you to build my car, we're not open on Sundays but I'll take it! Car is 100% stock right now, this car is gonna be insane when we're done with it. We can't thank everyone enough for trusting us with their pride & joy! We will try our hardest to raise the bar on performance, quality, attention to detail & customer service. Remember that we don't store cars, we work on them from the moment you drop them off until it is finished & ready for pickup. We believe it's good enough when the customer says so!
