To supercharge or not to supercharge...that is the question..

Robyn if the only reason to do it is to beat me, don't waste your time girly. I'll just have Sharky launch my car and you won't stand a chance. Save the 10k for girl stuff and leave the car stuff to us guys!
hahah, how's that? Makes you kind of want it even more now huh!

Like I said, I have not heard of ANY issues related to a EVO SC on a 996. For a moderate amount of boost, I contend there will be little or no adverse effect on the engine. Just lots more fun.

There are more adverse affects than just detonation - compression itself is hard on the motor. Your pistons are taking a beating with higher compression. Think of it like this - you have a piece of metal and a hammer. If you it the piece of metal for 2 years straight at say 11x force, and then you hit another piece at 16x force, which piece is going to fare better? Same goes for the connecting rods, bearings, etc. I mean it's just common physics - more stress = less life. Same goes for any mod - a short shifter probably will shorten the life of the synchros, etc. etc.
I'm not naysaying guys, I love modding cars and I'm all for supercharging the 996/997. I run more than twice the boost of a stock S4 on my car. BUT, you need to understand that forced induction is hard on a motor. If you don't believe me, I encourage you to call a tuner and get them to show you IN WRITING that supercharging the 996/997 will not put any additional stress on the motor.
Lasltly, I believe the EVO SC came out a little more than a year ago - how many miles have people put on it? Again, don't want to start a flame war, just something to chew on. And the argument that you only use boost 1% of the time is fine, but really not relavant. Someone I know ran 2 bar through his engine for 2 days, and his leak down tests are so bad it's laughable.

although I am curious how a 'short shifter' might stress synchros.

That example by itself is laughable.. We are not even talking 25% of that kind of boost. Any guy that increases his compression ratio to 29:1 is an idiot and know nothing about physics. There is a point that the amount of boost reaches a maximum before the heat caused by the compressed air starts reducing power. I am sure that his pistons had nice little holes in them too.
However, I suspect that this guy was just pulling your leg.

2 bar on an Audi S4 != 2 bar on a Porsche. The point was, there is a limit on safe boost levels, and for some engines that limit is 0.
I should note that the owner did not run those boost levels - the guy tuning his car did - and it was a well-known competition. Don't want to go into any specifics, but the car was running lots o' boost.

I am speechless, I have no comebacks, we'll have to wait and see on the 1/4 mile with you, Collin and myself...but I think I will be the slowest =(
But damn this thread is fun...
Hmm, hey Alex, I might have to get my Top Secret 9sec. car project going...

Robyn, please tell me that you're not going to spend $10k on a supercharger just to get even with Kirby? a watch is a beautiful thing, something that you'll be able to appreciate every time you see it, a super=charger is so far from what we're talking about that i can't even make the distinction. but, then again, if you're needing to keep up with all of your pals on the board, the supercharger is probably a must, as many of them may not know how to appreciate a fine piece of jewelry. as for the tiptronic, christ almighty, i'm not sure how anyone could possibly own one.....do Porsche cars really come with such?!?!?
have fun
have fun

Robyn.... YOU WILL LOVE IT!
To have a SIGNIFICANT surge of power available at your every whim is a very, very, very fulfilling feeling. To be Master of the Road, King of the Hill... it truly brings you closer to GOD. And that's what life's all about, isn't it?
