Hey guys,

I'm thinking of installing VX cam in my '90 740, with B230F engine and LH2.4
injection, but I'm concerned about loosing low to mid range torque as
compared to my original M cam. Has anyone had any experience with the
performance of VX cam? It'd be great if I can see a power / torque curve of
the B230 engine with M cam and VX cam....

Will,
I put a VX3 in my '88 240 a couple of years ago before a trip from San
Diego to Boise, going through mountains has never been so much fun. Very
noticable difference, well worth the money. I have an automatic and the
power band of the cam comes on right about 2500 rpm, just about right for
spirited driving, really fun from 3500-5000.

Hi Dave,

VX3 is basically a VX cam but is retarded 3 degrees, from what I've read...
wouldn't VX give slightly better performance than VX3?
I don't really know THAT much about camshafts... but I'm trying to learn.

This is true, the change in lobe timing moves the power band down the rpm
range making the cam a little more automatic freindly, there is no change in
the overall performance. For turbo cars some people use an adjustable gear
to give even more low end, I fiind the cam pulls just fine without it.

William have you tried to contact Mike Aaro? He contributes to Turbobricks Forum
and knows just about everything to do with Volvo tuning. He would be only too
happy to advise you on all aspects of your intended modifications. If you search
the list (Turbobricks) you will soon find his address.

Cheers, Peter.
