How Much Horsepower Does a Ls4 Have

Other, more involved upgrades to the LS4 are really not practical. The intake manifold limits the engine’s ability to breathe. The FWD driveline can really only handle about 400 hp. Even upgrading those components to make more power will result in issues with the steering and handling of the car.

How much HP can a stock LS4 handle?

Other, more involved upgrades to the LS4 are really not practical. The intake manifold limits the engine’s ability to breathe. The FWD driveline can really only handle about 400 hp. Even upgrading those components to make more power will result in issues with the steering and handling of the car.

Is the LS4 a good motor?

The LS4 is a bad choice for an engine swap, but it can be improved when used in a FWD car or mid-engine kit car swap. Install a 160-degree thermostat before heading to the chassis dyno tuner as it will give them a wider tuning window.
