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 
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.
Didn’t Count Vohn say headers will be (most likely) necessary for stage 3?
I thought he said the headers might be more valuable on a stage 3 setup than they were on stage 1 or 2 cars, on which they don’t seem to help.
So what is the problem with the headers/TPs/HFCs? Is the factory setup just that good or are these mods not being tuned for to get the potential gains out of them? Is it as simple as supply and demand since we are working with a small displacement motor/supercharger there simply isn’t that much air to scavenge?
Just trying to gain some knowledge on this since other supercharged platforms seem to get very noticeable gains with a header/tune setup.
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
why hello there whitehawk.
like I posted before, my stage 1 car with headers made a few less horspower/but similar curve than NWS4’s car on the same dyno running stage 2.
Obviously that doesn’t take real world acceleration into account, but its telling that they at least do something.
This makes sense Saki, as I stated, I am not arguing the fact that for the cost they are not worth the $$$. For your question, no, I would not purchase them. I purchased them for power(more to less), sound, and to have something most did not.
I wonder if I can port my supercharger and get force some more air through that bitch!

The headers may still have their day in the sun. Maybe stage 3. Maybe someone writes a tune that can take more advantage of them.
But since the B8 S4 is not reliant on getting exhaust out to be efficient, and rather has the benny of the 1320 RAMMING air in, I don’t see any huge advantage to any of the current exhaust mods on the supercharged cars. We also haven’t found that the stock manifold, downpipes and catback are terribly ificient either.
It’s not like the NA V8 B6/7 S4 where they are in need of free flowing exhaust to help the engine draw air in on the intake side. The B8 S4 is more about keeping the blower moving air efficiently.
We see this on the B7 RS4 with the APR TVS1320 kit. The results from the cars with full exhaust aren’t far off the cars with stock exhaust (although stock RS4 exhaust is pretty excellent, with headers from the factory). But APR went 11.83 with stock downpipes and all 4 cats on the RS4…where we KNOW the cats on the RS4 are a big restriction that fuck up performance. Remove them on an NA car and you’re picking up 20-25 WTQ. But, the APR RS4 just didn’t care.
Blackhawk, Welcome to the forum! I don’t think it’s a tune thing I just don’t think the stock blower pushes enough volume to make the exhaust a bottleneck… The intake is the restriction currently… I’ll let the more knowledgable guys chime in though… CountVohn made a good post on this a few months back… Good read!Again, welcome to AR!
Thanks for the greetings Primetime and Not Armed.
That is what I am thinking as well, there just isn’t enough air volume being moved to net real gains. As some have said, potentially with a larger displacement SC they(HFCs/TPs/Headers) will provide more noticeable gains.
