E30 Zone

Just had the old girl on the dyno an after opinions on weather it's a good result or bad one
M52 running an m50 manifold with a danthe map, k&n filter
I got 207.8bhp and 204.7ft-lbs

Very close to mine

Henry had a few more if I remember was about 225bhp

My totally standard B28 ran 180hp and 200lbft with a tank full of asda finest on a known low dyno so I would say if its know to be a conservative dyno then your pretty much spot on.

Dyno variation can easily be 10% given you are measuring at the wheel contact patch and back calculating it at the flywheel.

People can say that pretty close to normal but it’s impossible to say without seeing the full curves and AFR’S as to whether it’s a good result. I guess what im saying is of all the information you can get from a simple power run the peak torque and peak hp is a mere fraction of the story”¦.

Mine was 212 bhp and 202lbs/ft with a bad air leak!! I need to get it checked again now the air leaks have been fixed, as it drives a lot better!!

Thanks everyone I was told the afr was bang on though

hi guys how much does it cost to do the m52 engine swap

That depends entirely on who is supplying the parts, whether you are doing the work yourself or paying to have it done, and the quality of the work to be done.
Anything from making a small profit on the whole thing, to paying out thousands for a quality turn key job.

2k to 4K dependant on quality of fit!
Hope that helps! Well worth it!!
