Sparks Racing Aggressive "drop-in" camshaft CAMH04450TRXA $215.95
i have the stage 1 and 2 hotcams sitting on the shelf.
i havent used either... because i dont have a 450r .... yet....
but ... what im told is... the stage 1 hotcam is more for a low end improvement over stock. the stage 2 is a mid to top improvement.... even better the the HRC. the HRC is sort of in the middle of both the hotcams... and as far as the sparks... i havent heard much about it.
Actually there are only a couple companies making cams for these engines. Hot Cams is the only company besides Honda Racing Corp. currently making billet cams. There are quite a few people MARKETING cams though. Some of the engine builders may have their own grinds though and use someone to grind their cams out of an OE camshaft. I seen at Daytona where Web is supposed to be making billet cams but haven't heard anything since.
I talked to web a couple weeks ago, they have 2 cams available now, a top end and a bottom end. Also did you know that web makes the cams for LRD? They told me that they were working on some of those too.
