For anyone that's interested. (not sure if this is the right section)
Always wondered what power the m50b25's make as I've heard 3 common figures : 170bhp 180bhp 190bhp. So I took the car for a dyno run today at WCP (West Coast Performance) in Kerry. Sound experienced people there with a good reputation and known for more accurate figures. They've tuned and built many rally/time attack/drift and road cars.
He did a number of runs in 4th and 3rd gear here are the results:

182.8bhp 180ft/lbs
Very happy with this thought it would be somewhere between 160-170bhp.
