Has no one noticed that some have proven hp increases with the m50 manifold while others have proven results of a loss? These stats come up everywhere and everyone has their own opinion on whethet THEY like THEIR car more. Just because John smith had a loss doesn't mean Harry Smith will have a loss too OBVIOUSLY by the various results. Is there something that we all are missing here?
I've done the m50 swap on my 2.8L and I couldn't give a rats arse what others say, I know it goes better and I'm the only one I have to please.
So for all the tech heads that only crunch numbers then spit abuse to people for liking the change, maybe their just jealous they didn't get the result others have.
1995 328i obd1 (factory)
Jatco auto box
M50 manifold
K&N pod filter
3.46 diff (non lsd)
Decat and modified standard muffler
And mine goes way better than with the m52 manifold
So maybe its just luck of the draw lol.
