Hey everyone, im new to this page and im new to modifying my cobalt for performance. Iv been doing some research regarding supercharging my cobalt that has a 2.4l engine and automatic transmission. I have tons of things im not really sure about because this is the first time i have wanted to boost a car. Im looking forward to going for a cheaper way to supercharge but if it cant be done that way no big deal. So anyway i have heard from a friend that i wont need to do anything but slap a supercharger on my engine with the new pulley and possibly bigger injectors... but i have heard that i could blow my engine even running low psi. The car has 150k on it and i havent had it for more than 10k yet. So im not really sure how well it was taken care of before. So would i need to do anything to my bottom end to make sure i dont blow it up? Im not looking to take it to the drag strip or anything just want it supercharged. So i wont really be running it to hard or anything but another thing i was curious was what size pulley would i need on the supercharger to keep a low boost like 6psi or so? Looking for the most cost effective and safest way to do this. Iv heard many different answers so i was hoping to find someone with alot of experience with the car on here. Thank you for the help in advance!
