Guys what is the highest recorded dyno run at the wheels for these cars? I'm going to start dynoing my 2 valve soon to tune it, it has already had one base line run on a Dyno dynamics machine and showed that it was running an AFR of 10 to 1.

I don't know what the spark was doing but I think there is more there. I think that once this engine is tuned I will get a good idea of what the 5.9 liter engine will produce as this current engine as it is only slightly modified.

Thanks in advance

Greg.

my 4.7 made 243rwhp the 5 liter 2 valve made 293rwhp and my current S4 engine with the 85 cams makes 320, and had made 335rwhp/335rwt.

ok greg, we are waiting to hear what your baseline dyno was... honestly you have more patience than me if you can resist posting the numbers untill you have optimised tuning, come on, lets see your dyno!

Very Good Brett! I have read a page that someone had posted somewhere that listed many many 928 dyno results. I do not know where it is as it was some time ago.

IIRC there was a euro on that list with 315 rwhp and i think it only had headers and not a hybrid. I also thought it was tested or worked on by devek. I could be wrong though. But I would take Brett's result any day.

My 2V 5.0L was 305rwhp. Stock EuroS intake and heads.

Interesting...I just put a 4.7 Euro engine with L-Jet injection and 84 US cams together for forced induction. I figure the baseline on this NA engine to be about 270 HP (crank) give or take. It should take well to boost.
