With all of the mods people have done to increase boost, I have not seen anyone mention changing the cam profile. The whole purpose of increasing boost is to push more into the combustion chamber. If the valve stayed open for a little longer, wouldn't you in effect end up with a similar result? <p>A while back I did run across one Volvo tuner who sold cams with a modified profile. I don't know if they were crap but, it does make an interesting "what if I....?" <p>And Kai, did your car pass the smog test?<p>Steve

Re: Cam profile - The search for more HP (SCFrost)

It sure will help, the problem is, there's no company out there that makes one for these engines.<p>I've used the cams from larger displacement volvo engines similar to our T5s, but the result was......dunno, couldn't tell. Didn't do step by step kind of comparison.<p>I know Heico was selling a set of cams, but someone I knew back then installed it on his car...didn't seem to make any difference either. I guess unless some company decides to make some very aggressive cams for our cars, only way to pumping more power is through turbo and other related upgrades.<p>Plus, the other upgrades are way more noticeable in these cars. We'll just have to wait until one day some company that is willing to risk themselves for the pointless R&D cost to develop something Volvo and get no customer even when they get it made. <IMG NAME="icon" SRC="http://********************/smile/emwink.gif" BORDER="0">

I have seen a few C70's with changed cams.<br>They were regrinded B5254 cams but they bend the standard rods for sure.

Email Unitek and see if they offer any white block cams (I'm guessing that they do): <A HREF="http://home.bip.net/unitek/" TARGET="_blank">http://home.bip.net/unitek/</a> <p>Also try KG Tuning (less likely, more OHV/OHC redblock stuff): <A HREF="http://www.kgtrimning.com/" TARGET="_blank">http://www.kgtrimning.com/</a> <p>And finally, Enem who apparently supply some (?) cams to Unitek: <A HREF="http://www.enem.se/index.asp" TARGET="_blank">http://www.enem.se/index.asp</a>
