What are the pro's con's of removing balancing shafts...

I know the only motors that these really apply to are the prelude motors. But the new K24's have them too. I am thinking about removing them from my motor and putting in the RSX-S oil pump. I have been told this will free up a few more ponies, but I am doing it just to make the motor a little more basic, especially if they are not really needed.

I have read that removing them adds a little more vibration in th cabin, but is there any real harm in doing it?

BTW this car will be used for Road racing and occasional street use...

 

you guys got nothing, ehh?

 

Well I dunno about K24's but on H-series the shafts supposedly make little difference. More vibration in the pedal and in the cabin/chassis in general. More vibration in general means that loose bolts will vibrate out, hoses and wires will wear if they are rubbing on anything else and possible short out/spring leaks. More vibration is a PITA if you are just driving around dealing with traffic and trying to listen to the stereo...

summary: 2whp and 3wtq across the board But this is an H not a K...

I suppose that there is no real near-term detrimental issues with taking the balance shafts out. Another benefit though is that you should have more oil pressure/flow that is not dedicated to oiling the shafts.

I get a lot of vibration (if I have my hand on the IM it'll make my hand numb for a second) at about 6000-6400rpm on my 97mm stroke engine but that is still not a K. So it's up to you.

yah I know what you are saying. I am not to worried about the extra vibration, the mounts that theyu make for these K swaps are pretty hardcore already...

I am more interested in someone that has had them out for a while, I want to know if there car is still running? Any long term effects?

Thanks Pirate, I will ahve to read that thread...

 

come on you Prelude guys...
