Nope, just a badge.
Just a bit of advice to your friend, I know a good bit of people who have done super chargers, both in real life and on the Z forums, most all of them have removed, sold, and bought a turbo kit.
Super chargers are great if you're looking at lower power with very little room to upgrade.
some people are making 400-500WHP but that's pretty much the upside where most turbo kits, that's just barely pushing them, in fact my GT35 turbo is hardly being used. turbo should easily make 600+ WHP
There's nothing wrong with superchargers, theres a few people that are very happy with them, its just surprising how many people have sold them and redone their setups. Thats a lot of wasted money.
for the record I was looking at the Vortech and Pro Charger systems. in the end, so many small things had to be replaced to make either kit somewhat reliable it would have cost the same for a legit turbo kit.
