B8 S5 N/A Dyno

[Jake@JHM]

Do you have a stock baseline on that same dyno?

The stock baseline is on there in red @ 319awhp. But that was already with the test pipe installed, air filter, exhaust and 94 oct, just no tune.
I also very recently did a carbon clean and even after that I felt a very noticeable difference in power but that was from the butt dyno lol
It must just be a healthy b8 because the next highest hp b8 s5 on the same dyno with everything I had minus the cat delete and exhaust but + snow performance water/meth ran ~300awhp and they preformed a carbon clean right before the run. But I was told the water/meth on that car was for reducing carbon build up more than power hunting.

This ☝️. If you want a true valuation of gains you must do a baseline, then post mod pulls (all on same dyno). I have a B6 s4 and put down 251 awhp stock and 282 awhp after do’s exhaust and tune on 93 octane. This was one a MustangDyno.

So why has JHM in all it's years never done a back to back 1/4 mile comparison between their flash and the stock flash on ANY platform B6 V6 3.0, 4.2 B6/B7 S4, 4.2 FSI S4, 4.2 FSI RS5...

How hard would it be to take 10 min, reflsh the car between runs and compare 1/4 mile times hmmmmm????

One possible reason would be, I've heard the ECU can take some time to adapt to a new tune, may be BS though. Or not as the tunes are what would be called 'Canned Tunes' much like OEM's do. Problem is every car is unique and in unique conditions from when it's calibrated. So some level of automatic/learned adaptation will occur. This is why every car should be custom dyno tuned.

I love the dyno argument. Dyno's are basically scientific tools. They are very accurate. Biggest variances come from operators, and or improper maintenance. Dyno's and the racetrack both have their uses and one cant really replace the other. Not giving dyno numbers is a cop out.

Although it would be ideal Jake, you know as well as I do that there's no way that he's installing a set of downpipes on the dyno.

So taking three different pulls 1) DP stock tune 2) DP tune and 3) DP tune E30 gives us all the information we need. Forget the absolute numbers, just look at the delta.

-The tune itself is worth about 12 AWHP

-tuning for E30 is worth about 10 AWHP beyond that

I'd also say that this dyno makes a solid case for running water/meth on these cars which is something I've been advocating to the S4, RS4 crowd for almost 2 years now to no avail...

The gains from the extra timing from the E30 also mirror the losses that a heatsoaked engine displays like what happened to Ape Factory during his last dyno session when he lost about 7-10 AWHP when heat soak set in on the Dyno when he was testing your guys own tune on his RS5 https://www.audizine.com/forum/showt...release/page11
