hey im wondering do you guys after degreeing your cams do you leave them there? or do you move the cam gears around on the dyno to see if anymore power can be had?
any info/input would be great

DDTECH

Its a starting point, Nothing more.

Proper Track and dyno time will need to be had to finalize settings.

D-Rob

Right. A lot of people think degree'ing in the camshafts is a be-all, end-all setting that means it's going to make the most power there. This is not true, at all. Every single engine will want different settings to make the most power in the area you're trying to target.

Where do you guys typically see the best gains as far as advancing or retarding timing?
I suppose to narrow it down ... for instance drag racing. You would want the powerband shifted towards the top? Or?
Thanks guys. I love informative reads like these.

DDTECH

To add to our conversation. Sometimes, Degreeing becomes an issue when clearances aren't known. Sometimes the recommended Centerlines pose a issue due to v2v or p2v contact.

Degreeing is a great place to start, but knowing clearances are great too..

To answer the above question, its going to depend on things.. little more information about the setup would help

D-Rob

Agreed on all points.

Knowing your clearances is more important when using a larger camshaft than anything else.

I tune too many cars that people have no idea what clearances they have, and tell them straight, "I will not be moving the camshafts unless you know how much room they have to move."

I can't agree more...

When I installed and degreed my DDtech cams I did a lot of measuring. Not only did I check P2V and V2V and the specified lobe centerline degree'd setting but I also used a number of different cam gears settings and made a table of clearances.

Having a table to reference all of the potential clearances you may be encountering when making cam gear setting changes while tuning on the dyno or at the track is very critical. If you plan to use another gear setting you better know for certain that you have enough P2V and V2V to run that cam gear setting without running into contact and resultant catastrophic damage.

I check my v2v.
I check my p2v.
I check my p2h.

Then I degree to see what it comes out to May work with clearance may not but it's not the end all very possible to make more power with diff cam adjustments.

Just know what your clearances are that's the main thing.

DDTECH

You're a Boss, sir.. Boss.

When i built my motor i made a table of clearances but I have yet to actually play with the settings on the dyno.

Would you care to share the most effective/efficient way of getting to the best settings?
what i mean by that is, do you advance and retard both cams until you get the powerband youre looking for and then play with one cam at a time for further gains?
or do you move one cam, 1 degree at a time and compare the changes?

^^^I've researched this before, as well as how ignition timing comes into play. Answers are readily available on Google. But it would be cool to hear these knowledgable cats chime in with a Honda perspective

so do you guys think if someone else is tuning the car it does not make sense for me the builder to degree the camshafts since the tuner will have to do it again?

TracerAcer2.2L

NO. If you don't degree them, how would you know where your cams are set in relation to TDC. The tuner doesn't degree them if you already have, he adjusts them from there
