Bolt-on engine modifications are performance mods that don’t require disassembly of the engine. There are endless options for bolt-on performance improving parts for nearly every application and budget. Below are just a few examples of bolt-on engine mods that we perform regularly at Accelerate Auto Repair. If you don’t see what you’re looking for, give us a call and talk with one of our service advisors about the performance mods you’d like to have done. We’re happy to help you decide on the best brands and combination of parts to reach your performance goals.

EFI System Upgrades/Holley Sniper

When you want more horsepower and a more reliable vehicle, swap your carburetor out for an EFI system upgrade. While our performance shop technicians can install any EFI setup that is on the market, we recommend the Holley Sniper System for everyday reliability, performance and fuel economy. Holley also has an ignition system that is designed to work with the Sniper setup.

Speed Shop supercharger installation at Accelerate Auto Repair in Rowlett Tx.

Supercharger Installations

A supercharger is an air compressor that increases the density of the air going into an engine, which means the engine has more oxygen. A turbocharger does the same thing – but it gets its power from the exhaust instead of being driven by the crank like a supercharger. You might hear people in the industry refer to superchargers as blowers. With either, since you’re adding more air, you have to adjust the fuel mixture to match.
