The supercharger kits designed for the Pontiac G8 can be modified to fit. A Roots-style supercharger is dependable and makes great torque in the low- and mid-rpm range.

There are companies producing kits for the Pontiac G8 that would be a logical starting point.

Turbocharger installations for a PPV aren’t common, but have been done.

A plate system has better distribution than the original intake, but an eight-nozzle fogger system is even better. If you’re wanting to get serious, a single-plane intake is less prone to break from a nitrous backfire. Keep in mind the tight piston ring gap is the limiting factor beyond that.

A nitrous oxide kit (at low settings) is great for street driving with stock internals.

We’ve addressed those in the next section below on fuel system upgrades. fuel injectors will support around 525 whp which is enough for most.

A 4-corner steam kit reduces hot spots that can cause the rings to butt and snap the piston’s ring lands.

L77 engines are a popular choice for people that want to stay naturally aspirated, but if you do decide to boost, here are a couple of things to address: Here are a few parts commonly used for an L77 cam swap: LS2 timing chain, LS7 spec lifters, LS2 timing chain damper, and thick-wall chromoly pushrods. Tech Tip: When you’re pulling the cam, switch out the spring-loaded timing chain tensioner for the more-reliable wedge-style (early) LS2 damper. This also saves you the cost of the installation tool. Want to save some shop labor? You can buy rockers with the trunnion kits already installed.

You will want to install a trunnion kit for added reliability. The stock rockers are good up to 175 lbs. Heads and intake good for another 40+ hp. Still can drive daily.įly-cutting the pistons may be required. Intake Duration 0.050 in.)Ĭonverter recommended. Turbo cams reduce overlap with less exhaust duration split in relation to the intake. Generally, supercharger cams and nitrous cams will have slightly more lobe separation and longer exhaust duration. If the car is turning into more of a weekend warrior, you can get into the 230-degree range without flycutting pistons. If you’re still driving daily, cams in the 215-220 degree intake-duration range can be tuned to idle like stock and still provide good mileage.Ĭams in the 220-225 range are a little more serious, but are still easy to tune and driveability is still good. What you’re looking for is power gains really starting around 3000 rpm for best average power between there and 6500 rpm. It’s not a bad choice and will make a lot of power at the top of the powerband, but there are better choices. If you’re doing an AFM delete kit, there will never be a better time to swap in a cam.Īn LS3 cam isn’t a bad choice, but it’s only a little bigger than the L77’s factory cam.Īn LS9 cam is the next step up. … Upgrading the L77 Camshaft and Valvetrain Before going to the tuner, we recommend installing a colder thermostat to open up the L77 tuning window.īelow are some more upgrades you can make to improve the performance of an L77 engine. Getting a tune makes it easier to dial in a bigger cam and injectors later on. Camaro differentials bolt right in with ratios starting at 3.25.

Torque limiting can be completely shut off.

Raising shift points and firmness (see above).

This is important with a Caprice PPV’s 2.92 rear gears.

Raising the factory redline keeps your vehicle in the meat of the powerband longer.

Correcting the fuel and ignition timing tables.

We recommend that you talk to your local chassis dyno tuner and decide on a computer programmer. So how do we deal with that? Easy! We can tune it out with a AFM disabler or increase performance overall with a programmer. A set of headers and a catted X-pipe flow a lot of air, but the drone becomes obnoxious. The factory exhaust system is very restrictive in an effort to reduce the 4-cylinder mode drone.

… How to Get More Power From Your L77 Engine (Bolt-Ons)įor many people, upgrading an L77 starts with adding a cold air intake. Performance is valued if it can be done without flushing money down the gas tank. This is because many of these engines are still used in commuters.

This upgrade guide is going to be a little different from most of. The L77 makes 362 horsepower and it’s a workhorse. The L77 is a newer version of the L76 with added Flex-Fuel capability.įirst offered in 2011, it came in the Australia’s Holden VE2/VF, and the Chevrolet Caprice PPV (read: cop car special) through 2017.
