Does anybody out there have any horsepower figures from a Vortech G trim with aftercooler on an otherwise stock M6 LS1 with just a catback? It will probably make 8-9 psi on a stock motor I assume.

Yeah they make about 460-480rwhp in stock form. And can make about 550rwhp pretty easy with a pulley swap fuel injectors and tunning.

I am going with 60# injectors for room to grow and a custom tune.

I,ve got dart heads and a fast intake and throttle body,When I first put the supercharger on it dynoed 488/524 with the trans going out. raced it that weekend it ran 11.90 before the trans said goodbye. I changed the trans tried it again and went 11.20 so I,m thinking a little over 500hp a4 trans,9inch rear

Before I did my swap mine had a 2.95 pulley and it was around 8-9 psi with a set of 317 unported heads, ls6 intake, and full exhaust it was right at 500rwhp. If you did a g-trim with heads/cam it would put your stock bottom right at rod breakage territory.

I,m running about 8or 9lbs,I,ve only ran it about 15 times but sooner or later I,m sure I will be looking for a forged bottom end. No problems so far though.

450rwhp stock with a blower. I know a guy putting down 550rwhp bone stock with longtubes and a g-trim on 9psi with e85. I put down the same numbers with a cam, full exhaust, ls6 intake manifold and 8psi on 91 octane. Same blower.

Make sure you have your crank keyed if you get a supercharger setup though
