It’s time to button up Operation Air Flow. In Episode 1 we installed a CORSA carbon fiber intake on our 2009 Corvette coupe with the help of our friends at Smokey’s Dyno and Performance. Then in Episode 2 they helped us bolt on a CORSA Sport performance exhaust system. Prior to each episode we ran our C6 on the dyno at Smokey’s so we could compare the stock horsepower and torque numbers to those after each component was installed. Now it’s time to share the results.
After our visit to CORSA Performance last month we headed over to Smokey’s Dyno and Performance in nearby Akron, Ohio to check out their first class custom shop. Smokey’s is a full service tuning shop offering everything from ECM tunes to custom wheel and tire installation. They specialize in all makes and models but, of course, we were there to talk Corvettes.
Most of us will never have the chance to drive, much less own, a supercar like the 2014 Hennessey Performance HPE650 supercharged Stingray or the upcoming 2015 Corvette Z06.
But while we’re dreaming, let’s go ahead and compare what we know about these two dream cars and try to come up with a conclusion about which one we’d take.
If you want exclusivity, then the Hennessey might be your best option. Only 100 of the cars will be produced, and with an engine tune that cranks out 650 horsepower – 25 more than expected in the Z06, the Hennessey definitely will have its fans.
I really like how the Corvette Stingray sounds on these dyno videos. Like this one from Late Model Racecraft after a Heads/Cam swap. With those upgrades, the car is pushing 470 rwhp. Headers coming next.

Now that the tuners have their hands on the new 2014 Corvette Stingray, we’re starting to see the aftermarket world works its magic. LG Motorsports has a Z51-equipped Corvette Stingray and they’ve already added a set of their popular Long Tube headers to the LT1. Still equipped with the stock GM tune and air assembly, LG saw a gain of 30 hp and 45 ft-lbs torque.
Like some other well-known tuners and performance shops, Pfadt Race Engineering has been itching to get their hands on the new 2014 Corvette Stingray. Pfadt has big plans for the C7 Stingray with a new line of parts and a performance upgrade package they’re calling the Pfadt P58. The package is expected to boost the LT1 from 460 hp to approximately 580 hp.
But before all that can move forward, they first needed to pick up the car.
Here’s another tuner that has recently got their hands on the 2014 Corvette Stingray. Hennessey Performance announced early on their plans to upgrade the new C7 Corvette and that process begins with doing a baseline dyno test of the car.
The new 2014 Corvette Stingrays just hit dealerships beginning last Friday and already one customer has taken his new C7 to Lingenfelter Performance Engineering for a couple of baseline runs on the dynojet.
How much horsepower will the C7’s new V8 engine be able to produce on the dyno?
Well, Jessi Lang with The J-Turn web show for Motor Trend wanted to find out so she took a 2014 Corvette Stingray to the K&N facility. With Robert “Pops” Calles, product tech with K&N, behind the wheel, the blue Z51 was taken to the limit on the dyno, literally.
