LOL - ya the voluminous amount of time slips showing those 12 second numbers must all be wrong. Come on, man, like forza said, just do some searching on here and AZ and you'll see plenty of good 12 second times.

Since you are well versed in this could you post a 12.0 - 12.1 time slip and video for me to see? I mean all youtube videos are real aren't they? I will be happy to put my knowledge of physics aside if you can simply show me a piece of paper with some numbers on it. LOL!!!

To run a 12.0 quarter mile time you would need about 420-430 wheel HP. I'm not trying to be a hater here but common guys lets get real.

Sure. Here are a few:

Ron, do you have video of your best run? I couldn't find it.

Alright you win. Your car has over 400 hp!!!

Yeah, it's possible with low drag coefficient, great 4-wheel drive traction, and Launch control.

Well actually it's not my car - Primetime earned the honor of fastest B8 S4. I'll defer to him on the validity of his dyno readings. But I can GUARANTEE you that he is not running 420-430 whp, which you claim below to be absolutely necessary to get into the low 12s.

Isn't that kind of the point? To drive around and provide feedback?

Disagree. An exhaust modification for a street car is a compromise between sound and performance. There is a reason race cars sound the way they do. The point isn't to simply add the MOST horsepower, it is to find a happy medium, for each customer, that maximizes the benefits of performance AND sound.

Not true. There are actually four of us. We all have different roles. "I" own the B8 S4 and as a result it makes sense that "I" am responsible for the B8 S4 content but "we" all work on the reviews and "we" have an equal vote on the recommendation decisions.

As for the rest of your post, I would be extremely hesitant to compare what "worked" exhaust wise across platforms. The exhaust requirements for a NA V8 are not the same as a supercharged V6 and making assumptions based solely on the diameter of the exhaust tubing is not logical.

So the guys have pointed you to some solid data from a reputable source? How about you show us some data on why it's impossible to run 12's with the numbers Ron has documented.

I would wager that this is correct depending on the dyno. According to APR, a car running 100 octane Stage 2+, which primetime has, would put down just over 400 hp on their dyno.
