Does anyone know the specs for Type-S cams? Is it anything close to what's below? It's the specs for Crower's Stage 1 cams from their website. I honestly don't know if Honda and Crower use exactly the same measurements, but I thought I'd check. I asked them again about the "sharpness" of Type-S cams, and if they reprofiled them slightly, but I don't know what they'll say.

Advertised Duration:
Int-291 mid Exh-284 mid

Duration @ 0.50"
Int-246 mid Exh-239 mid

Gross lift @ 1.55
Int-.465 mid Exh-.465 mid

From what I know, the Type S cams have more lift than any of the Crower grinds advertised. Supposedly the Type S cams have 12.2mm of lift (0.480").

I don't know the duration specs, but duration has to be measured at some amount of lift.

Duration and lift don't give any info regarding profile. You would have to get either a plot of lift vs. position (not common), or a picture of the cam.

So you'd really have to compare the two sitting side by side to guess if the Crowers would do the same scoring as Type-s's could then?

Website says $680 a pair, plus $100 for custom grinds. Spring/retainer sets were $421. This is some more info. I got from Brian Crower (he's pretty quick at responding), does his explanation of the lack of Type-S cam problems make sense?:

"H22 cam info...

Stage 1 = factory springs OK, factory idle lobes.
Stage 2 = factory springs OK, up to stock rev limit, recommend Crower/Eibach spring
#68187 if over. Hopped up idle lobes, but still daily drivable. Slight lobe at idle.
Stage 3 = Aftermarket springs required. Rough idle.

Note: Our spring #68184 will be available mid April.

As far as they Type S core problem goes, since we use our own cores and maintain factory
base circle, there is no rocker wear issues to worry about. The Stage 1 has more
aggressive ramp speeds than the factory intake and exhaust VTEC profiles, but duration
and lift are similar.

Thanks for your interest in Crower,"


The questions from me to him:

"First, I saw no requirements for upgraded springs and retainers like is
> mentioned for the B18/B16 vtec cams, does this mean the stock springs and
> retainers can be used on the H22 cams, I saw they are available, so I'm
> curious what's up with them? (specifically for Stage 1 and 2)

> Secondly, for Stage 1 and 2, are both vtec and non-vtec lobes different

well im gonna be ordering the stage 2's today without the spring retainer kit. Because i dont plan on changing the rev limit, or anything, because i dont know if it can be done without doing the OBD-1 swap, but i dont think thats possible with the SS trans, do u think i should be fine, or should i got with the stage 1's?

Dan, I already have Type S cams sitting around and am thinking if I should go with Crower Stage 1 cams instead. I also drive a SS, the Stage 2 has slight lobe at idle, I don't think it would too good for automatics.

Does anyone know if the Stage 1 is any better than Type S? They are advertised to gain 12-15hp. (not sure if this was measured at the flywheel or wheel)
Type S cams gives about 10 whp.
