Cam gears on stock cams
you could put gears on the stock cams, but I doubt you will be able to gain very much power, if any. You could probably smooth out the curve but thats about it.
I'm using spoon camgears on my stock cams, along with a VAFC for fuel tuning and I saw some good power gains and a smoother curve, but nothing drastic. I'm happy with the setup. So to answer your question, yes you'll gain some power and yes it's safe, just make sure to dyno tune, don't guess
I gained some good all-round power on stock cams with cam gear and VAFC tuning.
You made 186 HP to the wheels with stock cams? What is your setup?[Modified by eg-six, 9:20 AM 2/5/2003]
could you guys please explain what you mean by smoothing the power curve
what is the advantage of this?

I'm going to try to get maybe 190 with my stock cam maybe next year.
wow good looking plot for stock cams.
Did you try retarding the intake a bit and advancing the exhaust at all? Mkae a little more peak hp but sacrifice a little low end....
What header/exhaust setup was the 186 hit with?
Advancing intake & retarding exaust will wide lobe separation angle reducing overlap.
So you'll have less top power and more midrange.

The above illustration should be helpful. Note:Honda B-series engine rotate counerclockwise.

The reverse is true. Overlap is when both the exhaust and intake valves are open. The exhaust valves are closing at the end of the exhaust stroke/beginning of the intake stroke.The intake valves are opening. By retarding the exhaust cam , the exhaust valves close later, spend more time open with the intake valves. More overlap also occurs when you advance the intake cam. The intake valves open sooner, and spend more time open at the same time as the exhaust valves.

Stock cams...red-->green is tuning ecu and cam gears, blue was semi stock.
