Has anyone tracked carbon build up? - RS5

[jdmnomore]

Sup guys i have a few questions but first some background. During my 2 years of owning a B7 RS4 i drove about 40,000 miles. About half way through at around 75k i had a carbon clean done by my indy shop. They werent prepared for the labor involved and charged me $400 (lol) but did an amazing job. Needless to say there was the expected build up and after the fact the car felt noticeably quicker.

Ive been researching threads and have seen documentation showing the RS5 dynoing pretty low on multiple occasions however I am not able to find many if any quarter mile times so am at a loss as to how bad carbon affects our cars. Has anyone had a cleaning done? If so did you do any before or after dyno or quarter mile runs?

Also whether you did or did not address the carbon im curious about what quarter mile times you guys are running or have seen from stock/modded RS5s.

Thanks in advance and obligatory pic of my RS..

I'm driving an S5 and going in to get a carbon cleaning first of the month after low dyno numbers. Gonna dyno again after cleaning before I put my tune on.

A friend of mine has a RS5 that I service and he let me take it to a private event at a dragstrip. At the time it had around 28K miles with no carbon clean, full of stuff, and had an AWE catback exhaust. My fastest pass was a 12.50 et @ 110 mph. APR ran a stock RS5 with like 1K miles at the dragstrip to see 12.43 and 12.48 ETs @ 110 mph. I don't see carbon buildup being that hateful on the RS5s just like how Sakimano ran a 12.75 ET @ 108 mph in his non-carbon cleaned stock B7 RS4 with like 50-60K miles.

Interesting Bones its weird seems like it shows up on the dyno but not onnthe track. Im starting to look at power mods here and there just recently installed the eventuri intake so i want to make sure im getting max output. Will probably head to the track some time soon so set a baseline.
