BMW E30 M10 - Full Head Race

[@danielsilvabrum7583]

Bom trabalho, quanto % aumentou o duto de admissão ?

[@carsandwhisky2002]

Nice ports but I'm noticing that you are removing material from the bottom of the intake port? Most shops only cut from the roof on these heads. Do you have any flow numbers and dyno results? I race an m10 and always looking for better cylinder head flow.

[@Hermiwalle]

yeah me too, they should have kept the flat floor and just raised the roof

[@karlssonengineering]

Where do you find that info? That is not correct. The ports are raised about 30mm and the inner radii have been welded up with material that filed to a new radius like a "tounge".

[@carsandwhisky2002]

Ahhhh that’s very cool. I’ve been trying to find a shop in the US to do this.

[@TurbineResearch]

what size valve do you use in these m10 race heads?

[@karlssonengineering]

That´s low boost on a 72mm turbo. It made later on 931whp in the dynapack with bigger turbine.

@@karlssonengineering I have been watching your videos since I was a kid. Your 2002 and other Swedish M10 monsters inspired my entire addiction to turbocharging !

[@mikaelhiatt]

do you sell these?

[@karlssonengineering]

Yes.

[@camholliday6142]

Interesting that they are using a 118 head, any particular reason

[@karlssonengineering]

its based on a 1.8I cylinderhead. thats very modified.

This is a bit belated however to my understanding you can pair a m10b18 head with a m10b20 body and have the same displacement but also a increase of compression going from 8-1ish to 8.8-1ish providing gains in horsepower and efficiency.
