I just installed a set of crower 404 cams in my LS motor today. These cams are normally used for built N/A setups but alot of local guys have used these cams in their turbo cars and made alot of power. Anyways, I was wondering if I should installed the cams stright up (set to 0* on my adjustable cam gears or if they shoud be advanced or retarded slightly. Any info would be appreciated

 

Bump for my man...


Is he on the right track ... somebody gots some insight on this ..

 

Set it at 0 and go from there; only the dyno will really tell where they need to be. There not truly going to be at 0 though.

 

i would retard the intake came some and advance the exhaust cam some. N/A motors like valve overlap while turbos dont

 

Dyno if it was that easy to set cam timing everyones car would run right

 

im not saying it would be right, but probably make more power than set to 0°

 

You also have to realize we have no idea what else this motor has.

 

Your right, if it where a dohc vtec motor; I would say get a degree kit from Xenocron. In this case the dyno might be his best friend.

 

404's are essentially an ITR profile. You saying ITR cam's don't have overlap?

:P

If the exhaust is free flowing enough, a boosted engine acts more and more like a NA engine.

 

ya sorry about that....

ya its got a stock bottom end for now but I want to finish out the rest of the race season with it. There's 2 more streetcar shootouts at our local track (cecil county raceway) and I'd like to make it to honda day in atco, nj and impot vs. domestic @MIR. Over the winter I plan on building another botom end with rods and pistons.
