Clean. Simple. Ready to roll.

Michael’s C7 Corvette was in for routine service and a full inspection. Keeping up with maintenance is one of the best investments you can make in any performance vehicle, and this Corvette is ready for another season of cruising.

Anyone can talk horsepower. The real test is time.

This C6 ZR1 has been with Speed Inc since 2015. Over the years it evolved from a bone stock ZR1 into an 1,100+ RWHP and 1,000+ RWTQ stock bottom end LS9 monster that continues to exceed expectations.

Recently it was back in the shop for its annual inspection and maintenance, including transmission and differential service, valvetrain inspection, and leak down testing.

Everything checked out with flying colors.
Nearly a decade of 4 digit power later this LS9 continues to prove what proper tuning, quality parts, and consistent maintenance can accomplish.

That’s the difference between making power and keeping it!

This one came in for more than just a dyno number.

Dan’s C6 ZR1 stopped by to remove the m**h system, repair a fuel rail pressure sensor issue, and upgrade from an older Nick Williams 102mm throttle body to the newer 103mm t/b.

The rest of the combination is no jokes.

Kong 2650
Cam
Long tube headers
ID1300 injectors
Cooling upgrades

With 20.7 psi of boost on tap, the final result was

1,014 RWHP SAE
877 RWTQ SAE

Big power gets attention.

A properly sorted combination is what keeps a car enjoyable long after the dyno session is over.

When you’re chasing 4 digit horsepower every part of the combination matters!

Matt’s C6 ZR1 was back at Speed Inc for fuel system upgrades to support the next chapter of this already serious build. The result?

1,028 RWHP SAE
889 RWTQ SAE

Those numbers don’t happen by accident.

Making power is one thing. Supporting that power with the right fuel system is what keeps a combination reliable, repeatable, and ready for whatever comes next.

Safe to say this ZR1 isn’t done evolving.

Sometimes it’s the little details that completely change the look of a car.

chicagoautosports (CAS) brought us this C8 Z06 for a set of Paragon Performance lowering collars giving the car a more aggressive stance while maintaining the drivability expected from a modern Corvette.

The before and after photos tell the story.
A subtle change. A completely different attitude.

Thank you to Chicago Auto Sports for trusting us with another incredible build.

If you’ve been around performance cars long enough, you know there was a time when 750 wheel horsepower was almost unheard of.

Today, that’s exactly where Vick’s 2016 Auto C7 Z06 landed.

Our LT4 cam and DOD delete package paired with a Kong Stage X blower, Nick Williams 103mm throttle body, ATI 12% overdrive balancer, long tube headers, and Roto Fab Big Gulp induction helped this Z06 put down an impressive

SAE
751 RWHP
684 RWTQ

What really matters is having a combination that works together and delivers every time you put your foot down.This one does exactly that.

Back for round 2. 👀💪🏽
Mike’s C7 Z06 automatic originally came through the shop last year for a Kooks header and pulley package. This time it came back for the next step.

BTR Stage 1 cam / DOD delete
Kong Stage X port
Nick Williams 103mm throttle body
Update Dyno tuned

Final result:
744 RWHP / 660 RWTQ SAE
That’s a serious street setup with the power to back up the look.

This is exactly why we love building combinations in stages refining the setup, improving the package, and making sure every upgrade works together the right way.

Sometimes the smallest changes completely transform a car. This C8 Corvette came in with just 35 miles on it for a set of Eibach springs, and the before/after says it all.

Lower, Cleaner, More aggressive stance without losing what makes the C8 corvette such a great street car. Simple upgrades done right always stand out.

Which look are you liking?
stock height or lowered? 👀

We appreciate Chicago Auto Sports bringing this one through the shop.

What do you prefer on a C6 Z06 centrifugal or positive displacement?
