how much extra power do you think it will make over the stock intake manifold?

are you running the Alpina  B9 cam?

@bmwe24M6driver I really have no idea, but the engine has made 304 bhp with tripple Weber dcoes and a 284deg cam. Im using a Catcams 299deg. The stock alpina cam is a 280deg.

Just curious ,have you had the car on the dyno yet?

My warmed over 9:1 CR. B35 with a 292 cam some port work on the intakes

a miller MAF and chip made 202 RWHP.

Your set sure looks cool !

@bmwe24M6driver It´s going on the dyno this summer, just need to change clutch first.

I have an M6 and a 635csi

how does the system work with out an air flow meter?

[bmwtouring02]

@bmwe24M6driver It works great. I use Haltech e6x and this sysem supports Alpha-N (TPS vs Rpm.)

They arn´t a straight fit. You either need an adaptorplate or cut and reweld the flanges on the ITBs.
