Will Camshaft pass Calif. smog? I have a very clean 1990 240dl non-turbo wagon with 250,000 miles. Planning on putting 500 to 1 million miles on it, bar any accident. I have a new catalitic converter. I was thinking of installing a VX street performance camshaft (non-turbo) from ipd. I was wondering if anybody has any info if this new cam will pass Calif. smog? Thanks
The IPD VX cam is based on Volvo's original VX camshaft that appeared in the European B230FX engine.
Specifications:
Lift Intake: 11.37mm
Lift Exhaust: 10.65mm
Intake duration: 245.4°
Exhaust duration: 236.2°
Overlap degrees: 13.8°
"An excellent modern example of a high-performance camshaft is Volvo's own "VX" design. Featuring moderate-to-high lift, fair overlap, and good duration the VX cam has been used as a direct replacement for the B230F's anaemic "M" camshaft. This cam/engine combination was marketed in Europe from 1992-1993 as the B230FX and featured a strong (136 ft-lb) flat torque curve from 2900 to 5400 RPM -- improving engine performance dramatically. Peak horsepower rose from 114 BHP to 136 BHP -- a 19% improvement!
What the numbers or power curves cannot accurately communicate is the willingness with which the VX-equipped B230F responds. The reaction to throttle input is far quicker, with none of the roughness over 4000 RPM that the "M" grind typically exhibits. having personally used the cam for some time, I can attest to little change in fuel economy or idle stability
