How about 10.4 to 1 compression and a bottom end not made for that kind of horsepower. Stock fuel injectors aren't really large enough if the stock fuel pump could keep up which it can't. Fix all that and your ready to go.... oops now you need a rear end that can handle that kind of power because the 10 bolt is gonna be toast if you ever hook it up.
To add to that. The Vortech kits come with a t-trex and an fmu, so on low boost levels the stock injectors will supply enough fuel. Fuel really isnt the issue. As said above the 10:4.1 compression is extremely high for a boosted motor without forged internals, even at 6 psi. Mine lasted about 2k miles even with an aftercooler. Thats not saying that all are like that b/c there are some board members who are still on a stock bottom end with moderate boost levels. If you are an m6 car then yes your rear will be a problem, for the a4 guys it seems like they hold pretty good until you get deep into horsepower. Any blower combo will need to be forged eventually, some sooner than later.

LOL! You hit the nail on the head there! These cars are set up pretty well for the stock amount of horsepower, but not much else.

Just got off the phone with detective Beavers. He is mailing me paperwork to read over and fill out so we can go ahead with filing criminal charges against you. You're welcome to call him yourself if you think I am lying. 419-254-8974. So, you can either refund me now or I am going ahead and filing charges.

Have a good one!!!
