Keeping the C8 train going. This car already came in with a few bolt ons already, but got almost everything else to make it a max effort SBE set up. This was the most recent heads/cam car we just wrapped up. Except this one got a little extra flair to it. Fitted with a twin bottle, direct 8 port injected, NO2 system by Nitrous Outlet that’s controlled without any standalone ECU’s! This was something our customer requested, as NO2 isn’t our traditional route, but it sounded fun and figured if we’re going to do it we are going to do it right! It’s only on a 100 shot for now, but there are bigger plans to come with this one in the future.
Here’s the details:
- GPI - Gwatney Performance SS3 camshaft
- GPI - Gwatney Performance ported/milled cylinder heads
- Brian Tooley Racing valve springs/pushrods/dfm plugs
- Cometic Gasket MLS head gaskets
- Performance Design carbon pTR intake manifold
- Chevrolet Performance LT5 throttle body
- Nitrous Outlet NO2 system
- DSX Tuning flex fuel kit
- Mightymouse Solutions
- Eventuri carbon cold air intake
- Kooks Headers and Exhaust
- Twin Cities Performance custom dyno tune via HP Tuners
Car made 544whp & 486wtq on E85 motor only, and 645whp & 585wtq on NO2.

With the good news of TCM tuning now being available for the C8 platform, here’s a heads/cam car we did over this last winter. It was tailored to be a daily driver with calm manners but to have a presence when pulling up. See idle video and dyno graph at the end. This car turned out awesome! Overall is a great build for anyone looking to enhance there C8 Corvette, maintain stock drivability, but pack a mean punch behind the throttle!
Fitted with:
- GPI - Gwatney Performance SS2 camshaft
- GPI - Gwatney Performance ported/milled LT2 cylinder heads
- Brian Tooley Racing valve springs, pushrods, and dfm plug kit
- Kooks Headers and Exhaust long tube headers w/green cats
- Valvetronic Designs Exhaust Systems titanium valved cat back exhaust
- Halltech Systems, LLC cold air intake system
- DSX Tuning flex fuel kit
- Mightymouse Solutions catch can
- Twin Cities Performance custom dyno tuning thanks to HP Tuners
Final numbers were 536whp & 482wtq on E85 (red line on graph is pump gas)

Finally a sunny day! Happy Thursday y’all, nothing hits quite like a C6 ZR1. Such beautiful cars.

This one came in for general inspection, found cracked intercooler bricks along with a mess of other things. Made 610whp on the baseline pull and is leaving at a pinch under 750whp after getting sorted and dialed in.

Happy Friday!! Low mileage C7Z we built a few years ago on the dyno after some maintenance getting a few updates to the tune. Making consistent 1kwhp pull after pull. Will be a super fun street machine.
