A few people from around Minneapolis MN had a little dyno day get together this morning. It was my first trip to a dyno and went there with my t25 aero (formerly an automatic trans car, converted to a 5 speed by me in January). The day started off with the employee who was doing the pulls on the dyno not knowing where the key went in the first car to get on the dyno, a 2000 9-3 lpt, and making some comment about the engine being weird...I thought it might be a bad sign, but it turned out nicely after that.
I think there were 5 SAABs there...2 9000 Aeros, 1 Viggen, 1 9-3 LPT, and one 9-5 Aero
My best results for my 2.3 t25 Aero w/3" exhaust and K&N filter were:
196.8 whp at 5500 rpm
232.6 ft/lb at 3750 rpm
If you use the numbers from the stock 9000 aero and the stock 9-5 aero as references for the drive-train loss they made 193 and and 203 at the wheels respectively and that is 15% below the 225 stock figure for the 9000 Aero and a little less than 15% less than 230 stock figures for the 9-5 aero (but he has an upgraded factory intake from a newer 9-5 aero).
So, I'd say that the 197whp/230bhp that my car put out is pretty darn good for a t25 9000 without any software. And my A/F was rich enough at high rpms to allow for some MBC action if I felt like going that route (probably won't as I don't trust MBC's myself). The A/F was at 12.5 at 3500 rpm then tapered off to 11.5 to the red-line.
All I can say is that the filter/air box, DP, and 3" exhaust must have made a pretty good increase on my car!
