Cams

Hello,

what should I look for when choosing cams for forced induction(supercharged)?

Regards

Is it for a civic? D series? if so contact Jon at Delta Cams. Send him your stock cam, and he'll regrind it to a 272. It does perfect and the vast majority of people run that set up in their D series. He can probably help you out with a B, H or K series if you're running one of those

Oh also, he's in washington. I believe his last name is Brodwell if you want to find him on facebook. Stupid cheap too, about $100 plus shipping and handling each way.

Cams for any FI application need to be carefully chosen. in the case of cam profiles for a supercharger it's important to limit the amount of overlap as otherwise the intake charge can blow through into the exhaust during the overlap period. Any cam manufacturer will have specific SC grinds available though and the Honda market is flooded with quality options.

Hi Andre, thanks for the input. How much degree of overlap would you limit, also is it wise to sacrifice the correct timing of the cams to decrease overlap?

Unfortunately it's not that simple. The cam selection needs to be considered along with your turbo size and really it all comes down to exhaust back pressure. A small turbo that is responsive at low rpm will also be restrictive at higher rpm and cause high back pressure. This sort of turbo won't work well if you use cams with a lot of overlap. On the other hand large turbos that are used for drag applications result in low back pressure and often we would use cams that are similar in design to aggressive N/A cams incorporating a lot of overlap.
