Default Do I need an adjustable cam gear for SOHC?

I have a skunk2 gear and was wondering if I should keep it or sell it. How beneficial is it? I realize that with a DOHC you can dial out overlap, but what good is it on a SOHC?

I'm going to be self-tuning my car (or trying to at least) with uber and a wideband. If I need to adjust timing, can't that just be done by rotating the distributor?

you won't need a cam gear unless you have an aftermarket cam. Also the timing you adjust by rotating the distributor is your ignition timing...however you won't need to touch that if you have uberdata. With uberdata you tune your timing maps in the program.

I don't think there is a need for any single cam motor. THey are just wanting to be like the big boys with an adjustable cam gear.

You're gay.

With an adjustable cam gear you can adjust your powerband up or down in the rev range. Whether you have an aftermarket cam or not.

Please elaborate. Maybe I should clearify that I only mean that the results are really trivial, when you can just play with your timing and do the same thing. There are more advantages with a DOHC motor because of the over lap you can play around with.

How do you figure that tuning your ignition timing and tuning your cam timing are the same thing?

I am not assuming, now. I want to know why this works the way it does. I have a basic knowledge of how cam timing works, but whats it matter if you ajust the cam timing as oppsosed to the ignition timing, it is the same thing in both cases? This is one area I am not perfect in, I really do want to know why.

No it's not the same. In the most basic way to explain this, adjusting the ignition timing changes when the spark occurs in relation to TDC, and adjusting the cam timing changes when the valves open and close.

Alright we got this cleared up, a cam gear can be beneficial. You just need to have an idea of what you are doing with them. I am glad I know a little more about life now. haha. Take her to a dyno and get some power out of it.
