    Muscle Car Upgrade in Superior

    Boost up your ride

    It doesn’t matter what kind of car you drive. It comes to a certain moment when we all feel we just need a little more power. Your family car might need a new turbo engine, or maybe you feel you can handle a boost of power in your muscle car. Regardless of the muscle car upgrade goal you have, it is important to know exactly what and how to modify your ride, otherwise, you could easily ruin it. 

    Driving around Superior outdoors is delightful, and cruising in a well-powered car is just addictive. However, before looking for nitro kits and bigger turbos, it is important to understand how they work and how sensitive muscle car upgrade projects can be.

    Torque and acceleration

    When it comes to better acceleration, properly matching your engines torque curve to the vehicle is essential. Engine torque is what accelerates your vehicle. However, there are several ways you can achieve better acceleration with the proper muscle car upgrade guiding.   


    Turbos come in a variety of styles and installed by a professional muscle car upgrade technician can easily provide fuel efficiency or power as required. However, fitting correctly a replacement turbo is not easy at all. It requires professional muscle car upgrade expertise and skill. 

    Most car owners in Superior upgrade their car turbo to a larger compressor and exhaust housing. This is a popular muscle car upgrade project that will provide more overall power. Some turbos could be the same size as your current one but are simply stronger and capable of running more boost pressure without failing. 

    A turbo with a larger exhaust housing will give less exhaust back pressure which will increase your power, but at the expense of some low RPM power.  A larger compressor, with a standard size exhaust housing, will give more power, but the small exhaust housing can be restrictive at high boost. 

    Nitrous kits

    When looking to boost the acceleration of your car, a nitrous system is a great muscle car upgrade option. There are several performance levels, nitrous systems, ranging from 50 to 500hp. In Superior a 150hp system could cost about $500. Of course, the price could vary between brands and quality. 

    It is important to consider that too much power could break and damage your engine. Therefore, it requires an expert muscle car upgrade specialist to perform these upgrades correctly.
