hey guys, i got the rsm stage one s/c kit. i want to get a nice set of cams in the spring when i take my car in the get the head port n polished, and the new clutch put in. my question is, what cam should i go with? i've heard that there isnt any that'll work well with the blower kit but i find that hard to believe.
any thoughts?
the standard "secret" cams work well. one of the guys in our club runs that and a large TB and works well. another runs both those and a ported head and seems to be having a bit of trouble but not sure the excact reason.
I was under the impression that the 'secret' cams won't work in the LSJ?
Maybe call up JBP and ask them for a custom blower cam for your eco.
yea... LD9 cams don't work in the ecotecs. completely different.

Comp Cams makes a boost grind cam. Haven't tested it yet but I would love to.
I used to race cars, now I race myself.

nope. i don't pay much attention to sigs.
k well im gonna start callin around to find about about the cams, i'm also considering adding a front mount intercooler. i know its a low boost level, but i'd rather be safe than sorry. plus ive talked with rsm about turning up the boost come spring...

I know the reason. Nobody around here listens to me when I talk about those cams.
Oh well. He will have problems until he gets stock cams back in or a proper set.

it's not the cams. another guy is running the cams but stock TB and head and no problems. its obviously a combination of a few things.

My point exactly - it IS the cams... in combo with a ported head.
Swap them out and he'll regain his powerband back.
But hey don't listen to me I don't speak from experience as the first person to make the mistake of putting hybrid cams on a heavily ported head 3 years ago. Whatever.
-Chris-
the powerband is fine. the thing goes like a raped ape. it throws code after code and has running issues. not power issues. i'm thinking an adjustable rising rate FPR with fine tuning will solve issues.

It has NOTHING to do with the cams.
You speak from experience, but unfortunately, not enough.
Porting your head will have little, or no affect on what cams to run. The secret cams are so mild, and there is so little difference in lift and duration, they will not affect your poerband AT ALL.
If you have a problem, it is not with the cams, but with your tuning. You can't just sart swapping parts in, and not consider your fuel management. Almost any cams will work with your supercharger setup. Its all about the powerband you want to run, and your ability to control the fuel after your cam install.
I will repeat this again.
THERE IS NO DIFFERENCE BETWEEN TURBO/NON-TURBO CAMS. ITS A MARKETING SCAM.
If somebody starts to tell you a story about too much overlap for your application, you will know right away that they have NO IDEA what they are talking about. It is complete BS.
Decide what RPM you want to run, and go from there.
I race turbo cars, build enfines,,and have a business grinding, and selling custom perf. cams. Before you ask, no I don't have any grinds for your application at this time.
The front mount I/C is a great idea.
yes exactly. a combination of things has caused a problem with the fuel/air delivery or how the GM computer controls it. it'll get figured out though.
Front mount is a waste on an rsm setup, your making 6psi at most to start with on the stage I, you put an intercooler on it your adding weight, and dropping 1-2psi in boost pressure, its more effective to use nitrous or a Co2 kit to cool down the ambient air temp and theres no pressure loss.
The actual power you put the wheels with or without an intercooler will be about the same on the stage I kit, a ported head is a good idea, make sure when your getting one you have the EGR port shaved off the right side of the head so you can fit a larger pulley on for more boost, RSM does sell the pulley seperately (900) but you cant put it on a stock head cause of the EGR port, this is why the stage II kits include the head. But really 1500-2000 more bucks more on top of a kit thats barely given me a sizeable increase in power, I cant justify it.
IM me id like to compare notes sometime reguarding this
