Here's a little 94oct K04/RS6 'brid FATS to chew on...

Mike2kS4 · 08-28-2005, 06:01 AM

Details: Mid/high 80's out, full tank of gas and full weight driving home from work deal. I did about 7 3.4x's in a row, even uphill!

Boost: 1.55 kg/cm^2 spike tapering to 1.45. Quite conservative... Definitely more power available.

Flow: g/s is 290 peak on an 88mm ID maf!!

Peak Timing: About 18deg or so (hot out, XR with no timing pulled). Plugs need replacing.

Fueling: Still running a bit lean according to narrowband at ~.85. There's quite a bit more power there.

Sounds pretty good for total, no BS daily driver mode

100oct fun should resume in a couple weeks.

Thanks Jacob for the killer turbos, and MarkP for the ecux timestamp calc.

if it's already leaning on you some, where's the added power to come from? i thought the most performance you can get is when the car is running on the *leaner* side.

Impressive run Mike, was this was RS4 intake components?

I need to run some logs on my car, maybe tonight. I haven't logged in a couple weeks. I'm shooting for a 3.6 in similar weather.

We taper about the same amount, so it'd be nice to see how much later your peak airflow hits. My boost curve is more like 1.475bar tapering to 1.375bar, though.

We taper about the same amount, so it'd be nice to see how much later your peak airflow hits. My boost curve is more like 1.475bar tapering to 1.375bar, though.
