Re: Building the supercharger to the engine (75 3.0V6)

So, maybe I don't see the design properly but have you added a wall around the inlet tracts? For added blockage? Less is more? ;) yes, but better afr control for al separate cylinders. Very important when you don't use water methanol on stock internals and 0.6 bar, 95 octanet and maybe some more bo...

Re: Supercharged 12V/Stratos copy/engine tech type stuff

why don't you tune the supercharger itself. I read in Gregs book it can be done at Embree machining. Don't konw what the costs are and what the boost rise is for an m90 unit..? EDIT: m90 unit @20.000rpm 0.96 bar (think it's the 5th gen) more then enough i think 8) 8) 8) What exactly do the change th...

Re: worn cam, clatter

A question about the cam followers. Can you lahte them down if the surface is worn . I mean the surface where the camlobe meats the camfollower.

Maybe it gets to thin.. Anyone?

Re: worn cam, clatter

Hello,

I'm also replacing my cams for the qv model ones (alfa 75 3.0v6). Does anyone know the height of the lobe of the qv ones to make sure the second hand ones are fine. Tanks!
