You guys want numbers???

The main point was that it was an in house dyno by the company selling the product.

Sorry I didn’t define the type of comparison, but plain and simple…Primetime’s runs with a header car same day same track speak loudly. I have no dog in this fight, but this is audirevolution…the furthest from dynorevolution and vendorzine that you can get.

Why hasn’t Paper’s Eurocode dyno queen made it to the strip? Just curios.

Eurocode doesn’t have a dyno, they pay to rent one just like everyone else.

Ughh ok, so since you are making your final conclusion based off one track day using two different cars, how about evaluating my experience

Direct comparison, same car, better conditions pre headers. Why has no one discussed this, everyone is using one track event comparing the single fastest S4 ever recorded against another S4 who has no no other data, track days, driving experience?

Everyone claims to be fact based but some are concluding their decision based off a single day. Different cars, different drivers, similar mods.

As stated I am NOT saying the headers are some huge boost of power, I have even stated they are not worth any “gains” shown or not shown otherwise for the cost. I am simply wondering why, a fact and data based group of individuals is concluding their findings on one event, with zero logs(that I know of). Who knows if he was having timing issues or if there was anything else going on, do we know they were running the EXACT same tune?

Jeff, I was going to mention your testing but I figured I would let you… I think your data is valid and useful, Euro may not have known about it, trust me he is very objective…

Good to know, he sounds like it. I like intelligent debates.

This is all in good discussion euro, I am always up for debate! Don’t think I am trying to attack you as I am fairly laid back and don’t hold anything against anyone. I can come off aggressive sometimes though.

I just cant understand how people can make a conclusion off a sample size of 1, maybe 2, as well_armed has gone to track. Once again, its all relative, different track, car, driver, etc…

The engineer in me is out in full force, if I based my decisions on 1 sample size using different variables, I would not have a job very long.

I myself am undecided on the subject at hand, all I know is what facts I have, and there are not enough to make a decisive conclusion. This is the same reason you(prime) have not purchased them, there is not enough factual data to prove anything, in either direction.

I’m not really trying to argue…maybe I should say that any advantage of headers has been negligible in my opinion thus far. I’m not trying to say that Primetime’s track day with Imola was the end all be all of the discussion. I also believe…actually strongly believe, that the company who designs and sells the headers should be showing those comparison (same car with the same setup pre/post headers) instead of just pumping the product with dyno sheets.

Even your direct comparison has its flaws, how did your whole slip look? I’m not going to focus on your trap and ET. Were your 60s very similar? was the car faster the first half of the track or the second? Where do you think Headers make a true difference?

Lol, I’m really just here to get Paper’s punk ass to run his car somewhere other than a 35MPH side street.

I do honestly look forward to you and Prime going at it…good luck to the both of you! and trust me…your not being aggressive, I think guys like you are good for AR.

My apologies, 13.02.

Car got faster after 60’ picked up some speed.

Actually slower,

So the slightly better 60’

Still does not account for the heavier wheels and massive difference in atmosphere.

Even this is still not enough data in my opinion, I would need multiple runs to prove anything.

Thanks for the slips, I was really curious and the second half of the track looked great.

Same track?

I honestly cannot wait to meet Ron and run alongside the legend :wink:

We promise to get logs, videos, anything and everything, in order to give as much back to the community as possible!

Also some friendly competition!

On stock tune the headers will help a bit because the stock tune holds the car back so much. Your numbers make sense. On a tuned car though, they will do a lot less.

And frankly nobody has discussed your results because nobody really gives a shit about what headers do on stock tune for your platform. The tune gives 50-70 whp on the 3.0T so it’s an automatic that someone who is modding the car is getting a tune. The odd of getting $2500 headers without getting tuned are astronomical. For a short while you were an anomaly in that you got headers then the tune.

Let me ask you for your opinion as a b8 s4 owner…My tuning company have developed a product for the b8 s4 that gives a twenty five whp gain, but only on stock tuned cars. On apr/giac/revo tuned cars, my product provides virtually zero gain. Would you be interested in buying our product? Before you answer, can I show you some testing we’ve done on a stock tune b8 s4?

What’s that you say… You don’t care about results on stock tune because you’re already tuned? Well now you know why nobody discusses your old headers results.

Actually slower,

So the slightly better 60’

Even this is still not enough data in my opinion, I would need multiple runs to prove anything.

Lol… I do appreciate that but no legend just a car guy having fun and sharing his experiences!

Definitely will have some great data and discussions for everyone… Good stuff!

Yep, good competition, looking forward to the races… Just hope I don’t lose too bad? ;D

Oh your car sounds awesome and looks killer with the alu optics. and wheels…

Saki, great points!

I’m with euro on this, ec should provide more data! Oh and I want to see paper run, that is why I originally bumped a 6 month old thread… Lol
