Avi135 said:yush1 said:Hey guys. Small update. Went to the dyno today at CS Auto. Obviously the car is stock. I was shocked at the power it made. Just to add some perspective, the was a M135i, LCI, with a JB4, upgraded charge pipe and a full exhaust by TMSS which made 240kw. Below is the graph and a video.
Impressive!
I think the m135i that ran 240wkw and 505Nm was run with the hand brake up. It had bootmod3. The shop damaged his rear brakes. I maybe mistaking cars though.
You are right. it was a white one. The car normally gives you a warning if you drive with the handbrake amd you would defintly smell the brakes. I did expect more from than M135. When i spoke to the owner before he ran, he said hes expecting between 240kw and 250kw. Maybe other M135i owner can comment. This was the LCI one.

A stock b58 makes 300kw at the fly? Thought it was an underrated 240fwkw, is the 60fwkw what bmw underrated that motor?
Indeed yes you would expect the 340i to be between what the 335i was and the M3/4 is.. My car makes 222wkw stock, this B58 makes 266wkw stock and the M3/4 makes well North of 300+wkw stock. So sounds about right yes :smilebounce: All BMW 6cyl turbos are quite underrated.
Im beginning to wonder how accurate dynos are? Are the manufactures actually under quoting this much? What is the actually power on the fly wheel than? I would like to compare on the same dyno on the day with another B58. Guys at the dyno kept insisting the car is tuned and its not possible. I guess some side by side action with other 40i's is the true measure. :thumbs:
