Cam Gear Settings - Honda Prelude Forum

mcgranman · 05-22-2002, 07:24 PM

Hey guys,
Got a question for any one who put cam gears(aem,ur or other) on a lude with stock cams. I was wondering what seemed to be the average best settings for the adjustable gears?

i.e. Intake +3 Exhaust -1( did a search and this was the only one I found, and that was a starting point for tuning)

I ask because I live in Germany and no one seems to know where I could find a shop with a DYNO. Want to get them, but don't want to have to set them to "0" until I return to the States.
Thanks, any and all responses are appreciated.

With Crower stage 2 cams, I have mine set to +2 intake and -2 exhaust.

Thanks bdb for your reply.
I know there are more lude techno wizards out there that have done this. So help a fellow luder out.

I am pulling this old thread because I need to find out which pulley is the intake pulley and which pulley is the exhaust pulley, if this is the way it works? I bought my car with the cam gears on it, Never touched them. But I have a feeling these guys might be my culprit for my car lagging.

Anyone have any pointers on this topic?

uhh, intake pulley is the one closer to the intake mainifold, and the exhaust pulley is the one closer to the exhaust manifold.

intake on the intake side, exhaust on the exhaust side. funny how that works out...

Thanks smart a$$, j/k

No for real thanks, I didnt know thats how it worked.

Anyone want to reveal there settings?

you loosen the bolts on the cam gear, and then rotate the inner section (which rotates the cam inside the head) to your settings. Then tighten the bolts back down to keep your setting.

yes they mean cam gears, but if you think about it cam gears are pulley's also, they are used to turn a belt(timing belt) they aren't usually called pulley's i guess thats what threw you off.

I personally like to call them sprockets.

I have a question for you guys on your timing adjustments:
When you state a positive change (such as +2), does that mean advance or retard? I would presume that means retard, but I want to check.

red92si · 02-13-2003, 10:56 PM

advance = +
retard = -

bb6flier · 02-14-2003, 05:20 AM

Adjusting is easy...
Lossen the ring of bolts, nuts or screws on the pulley
Put a box end 14mm wrench on the pulley bolt with the handle pointing up (this makes it easier to remember which way to turn).
Then either push the wrench to retard or pull it towards you to advance...
Then tighten the ring of bolts while holding the cam where you want your timing to be and your done.

In most cases;
+ = advanced timing
- = retarded timing

thanks guys! This does help.

hustler904 · 02-16-2003, 06:28 AM

does the timing belt have to be off when advancing or retarding the timing?and when doing this,I assume the inner hub assembly actually seperates from the outer gear teeth right?

tifs · 02-19-2003, 07:53 AM

I dont think the timing belt has to be off, since the inside portion moves only, then you have to tighten the allen keys back.

has anyone put skunk2 stg 2's in and adjusted the timeing. skunk2 says not to adjust the timing with the stage 2 cams because the valve lift is so high that you could hit a valve into a piston by changin the cam timing. anyone try doing this? or heard of this? I had my vavle to piston clearance looked at when my head work was being done, and my mechanic told me i had about an 1/8 inch clearance which isn't much at all. so i took my skunk2 cam gears off and i'm plannin on sellin em. supposedly the skunk2 cams are pre adjusted at the lobes.

tifs · 03-05-2003, 08:50 PM

This helps alot, cause I adjusted my cam gears, and I can feel the difference in pull around 3500RPM and vtec. I feel a good bit,

I was thinking about getting stage 2 cams also, but the info you just mentioned makes sense. But the gains will be nice, I think with the stage 2 even if you keep the cams at stock.
