Default You are all tools. If you bought this car just for a fast 1/4 mile, then you chose poorly.

These cars are the overall package. Go buy a used Cobra or Vette go do donuts all day.

Default I agree! You want to see these cars shine? Heres the link!

The crapy compression on YouTube sucks, if it catches your eye though you can download the full version on my website at

You need the Divx codec and its about 30MB

Default I totally agree. The car really does wake up after that break-in period.

Default Re: there are a few things that I'm doing....

I know that I'm going to get a beating for this newbie question...but here goes... I've got an 07 A6 4.2 s-line on order and am interested in giving it a bit more. Your 3 phase plan sounds great but it's also a little greek to me. Could you possibly give a little more detail and your gut feel for the performance improvement? I'd greatly appreciate it.

What is I/E/DPs? I assume exhaust and downpipes. APR claims a 25hp/35lb-ft of improvment. For roughly $2500, it seems like a great investment.

I understand the chip improvments. GIACs chips probably going to run $1K after install and get me 10hp at best. DO you have a recommendation on vendor?

now on to the third phase and here's where you lost me....

What's a valve job get me? Better seating? What's the benefit? $348 seems cheap for ripping the head off.

Ditto on the R&amp;R...absolutely no clue what this is...(I did say that I was a newbie)

Any recommendations on the cam and/or timing?

I've heard the lightweight clutch was a good to do. How about the rear differential? Any benefit to adding a limited slip differential? I know it's not an engine discussion but...

Sorry for the long post but any reply would be very useful.

Default That is a hell of a way to go bug collecting :)

Default Re: didn't see your post until now....

I/E/Dp is Intake, Exhaust, and down pipes it's usually the first step in performing your basic performance upgrades; (BPU) from there is a chip. APR is about $500 you want to call them to find a local distro.

Once you've done all the above you can focus on doing the light weight mods..I've removed the spare tire and bought a super light odyssey battery. Since I had to do engine work I'm doing the head work. But I would recommend some light wheels, suspension, and brakes which for me personally I have experienced to be the biggest bang for my buck, BUT they cost the BIGGEST BUCKS. Something like a 17x7 Velox PG-Rev10 that are 11.5lbs per wheel, with lighter suspension and brakes make a huge difference in ALL depts. acceleration, handling, stopping and of course weight.

Timing is handled by the chip, now the cam was the only item I changed my mind on because after installing the cam the ECU would need to be tuned and you're opening a whole new can of worms. better to say on the path than blaze a new one. (none of the chip manuf. have a program for the cam) The piston and valve paths "interfere" with one another (known are an "interference head") so having a cam that had a longer lift or duration may cause a catastrophic engine failure when the chip advances the timing.

I'm having trouble finding the lighter clutch flywheel...when I got it over to the shop the stock unit was completly different from what they thought. So i'm exploring other options. as for a rear limited diff...I would probably not do anything with it unless you've done everything else (including a supercharger) and you're really tracking the car and you can get any speed out of the corners.

Default Thank you. I'll start with the easy pieces!

I'm not as confident as yourself when it comes to that type of engine work.
