So I've decided to start saving for a supercharger for my 95 5.0 GT. I've looked at the options and I really just like the top mount Kenne Bell units. So I've seen some for sale, some are the new 2.2L units, some are the old 1.5L units. I am only looking to run 6PSI, Intercooling preferred, but still optional with that low of a boost number. So, will the 1.5L unit suit my needs (since they are soooo much cheaper), or do I have to cough up the extra dough for a 2.2L? This car will be my daily driver, so there are no plans to ever take it above 350HP (so none of the "Then you can't get to 750HP" comments). I just need to know which lasts longer, works better, will make me happier. Thanks again guys, this one has been puzzling me for a few days.
