How do RM cams compare to any other manufacturer (spec-wise)?

I was about to get crower 402's for my stock block B16, then RM was mentioned; I am having trouble comparing the specs between crower and RM and I do not want to get too big of a cam, but I also am not going the typeR route...been there, done that.

I just need some direction......

pm rocket he will tell you everything you want to know!! very informative man!!

 

can't locate "rocket"....

I just need the basic idea: What cam compares to crower 402's? Someone offered me used 402's at a decent price, but if RM cams are a lil more punch, I'll gladly pay a lil more for them. What RM cam is similar, if not superior to the 402's?

set-up:

built B16 head (springs, etc.)
stock B16 block (will be higher CR LS in 7months)

I just need info soon and the search function is a lil iffy (looking this stuff up for DAYS and still have no definitive answer.)

 

Rocket will not be answering anymore questions via his username

all questions will now be deferred to his distrubutors

with your setup, i believe the M22's are a lil bit much for your motor. The m22's are more for 11.5cr+ 1.8L's.

I believe either the M20's or M21's are good both have the same duration while the M21 have 0.1mm more lift. M20 lift is 11.5mm

 

i think with a high compression LS you should go with the m22's

 

What about the 402's? I had the CTR/ITR cam combo, and it was pretty weak. I need more power.

Any suggestions then? I was confident with my last set up (LSV, crower, etc.), but it was sadly lost.

I want more punch than S2S1, any idea? Every time I read a spec sheet, every manufacturer uses a different method to confuse me to no end.

 

If you want more "punch" than the S2S1 then I would do the BC3+. For a mild motor they are hard to beat, the M22's are gonna be complete overkill for your motor. Are you saying that you're gonna do a ls/vtec later on? What header and engine management do you have?

 

I will be using hondata and ????header. The LS block will be finished in 7-8months. I just want some punch right now that will carry over once I get the LS block prepped. I loved my last B16's rev-happy attitude, and want to have fun right now till the LS....etc.

I just need advice about all these new cams. I haven't built a motor in over 2yrs, and am very confused and listless as to all the new brands/combos/specs.

BTW, this car is set-up for the occasional autoX and drag race. DD is always on

Another thing.....stock B16 cams are 284int/283ex Why are the m20 and m21's # lower? Even the m22's #s are BARELY above the stock B16's advertised #s.

 

Rocket doesn't really do the M20's anymore.

For B16 I'd go M21. But since you're going 1.8 down the road. Go with the M22's. You won't have much of a midrange now, but top end will be killer. Once you go to 1.8, they will rock your socks off.

 

sweet....thanx

I htink i'll be going w/ the m22....unless anyone sees otherwise....

 

<ben stiller voice> do it

 

<creepy ______ voice> it shall be done...

ALSO (Sorry for all the hassle) What would be comparable to the M22x? I need options that might be a lil more cost effective JUST IN CASE...

Jun 3's are the closest cam to the M22's

 

what would be Toda's closest cam?

I'm just trying to get all my options together and make a purchase soon.

thanks for all the help BTW

 

From the specs I have for Todas, it would be the Toda B. M24's would be comparable to Toda C's. Rockets special cams for drag teams would +1 the Toda D's.

I completely agree, this is one of my pet peeves. Most cam grinders duration numbers are useless because there is no reference point. There are so many different way to measure duration and the tooling used makes a difference making comparisons very difficult. I like cam company's that give you ###'s that compare to a Honda type r (as a reference)cam measured their way with their tools and there cam measured there way with there tools. That way you know what the hell your getting. Webcam and crower are the only two I know of that do that. That way you can say well this cam has X amount of degrees over a type r and this cam it's X amount over a type r. Sometimes I think they do this so that you are forced to trust and believe them when they say put this one in it's wonderful. Dan

 

yea, its BS how everything is not at all related....I might end up going with the crower 402-2's ONLY because of the comparison on the web site and the fact that I have used them before....Not too mention, for the price of most of these 'other' cams, I can buy a trusted name, i.e. Crower.

 

There ia a 402A-2 and a 402-2 which has the bigger non vtec lobes have you tried both? Dan

 

I dunno.....?

 

Why compare, just get Rocket's cams lol.

I wouldn't mind getting RM's cams, but for the prices I'm finding, I can get Crower for less....Frankly I'd rather stick with names like Toda, Crower, etc.

I do have RM valvetrain and On quality

 

I would go with rocket motorsports, or skunks new pro series, both are excellent cams. I have never been impressed with webs or croweers

 

The reason for my loyalty to crower:

Several associates have made great power w/ stock blocks using crower products.
" " have blown motors, never the fault of ANY crower component.
Crower has been around for ages...Every domestic builder I know uses them.

I am always willing to try new things (usually) but when prices tend to be the same, I will always fall back on the tried and true.

But to Rocket for making quality stuff ( with my limited experience with them).

 

A local guy Jared was running Crower rods in his resleeved, Rocket CNC ported head turbo engine. A rod broke. Not installation or tuning. Crower said they'd give him a new rod. SOL on his damaged sleeve and head.

RM cams are made from Crower blanks.

RM M20's are slightly bigger than CTR cams. There is a comparison for you.

A member on here with a stock block C5, RM ported head, RM ported AEBS IM, SMSP header, Hondata S200 made 238whp on Churches dynapack with M22X cams.

Quality.... Look up the problems the few people have had with RM cams. They've all been taken care of very well by Rocket. A customer of mine bought some M22's. There was a problem with them not spinning in his head. Something with the cam caps. Rocket had him send them back to him. Rocket tried them in a core head and they spun fine. Still didn't work in customers head. He was given a full refund for the cams and was very happy about it.

I had a customer in PR that bought some M22's. He accidentally received 2 intake cams. He was overnighted an exhaust cam the same day he contacted me about the problem.

Rocket Motorsports quality and customer service is top notch. That is the reason they are the only cams/valvetrain I sell.
