Ok im a lil new to the car scene, and I have no idea what "cams" are. I mean, i know their camshafts, but whats the purpose of upgrading them? Thanks!

 

POWA, man...POWA

 

wut are the best cams out there then? Be reasonable guys!

 

LOL if your new to the car scene the last thing you are going to want to jump into is a cam...

 

The cam shaft is responsible to open up the valves, exhaust as well as intake. So with a different cam it can open up a valve more or less (called lift) and it can keep the valve open for a longer or shorter time period (called duration). If you keep your intake valves open longer and/or wider it brings in more air/fuel mixture in to the cylinder which equals more power if all the other components are adjusted correctly to the cam. So that's what a hot cam does, it increases lift and/or duration to alow more air/fuel mixture in the cylincer to create more power. At lease that's how I was thought.

Price sucks (about $500) but h.p. gain is 44-48 minimum.

 

I've heard 22-24 for VT stage 1 cams... mid 30s for VT stage 2. However, the stage 2 require new valve springs. Stage 3 might be in the 40s but the idle will be too rough for daily driving. It also requires new valve springs.
