Went out in my friend Seat leon cupra R with the vag com pluged in and got a peak maff of 224 g/s what sort of power ould that be running?

Should be about 260-265bhp. Can't remember the exact ratio, but its in that region. I'm guessing your mate has a remap?

If the calculation is the same as it is for the S4 then it's pMAF/0.8 .... which in your mates case gives him 280bhp.

I think 0.77 seems to be what they claim on the seat forums, but that would put the power figure at over 290bhp - beyond the limits of a K04 (unless your mate has a different turbo). I had my S3 dyno'd at Star recently and I think I was getting roughly 260 g/s and about 305bhp but I sold it a few weeks ago, along with the dyno plots and I can't remember exact figures.

The turbo is a K04 and it has a red dot racing Map. He is thinking of changing the map to an MRC map. That is a very good bhp result for your S3 (305bhp) did you have a standard turbo?

Its actually quite a poor figure for the S3 It has a GT28RS fitted and usually runs a bit higher. 330-340 depending on the dyno. It had an N249 valve issue so they were doing some logs to see what was up. Probably the only reason I can remember the readings.

I see alot of the seat boy's run those turbos. Bet it went well when you sorted the problem!!
