HOW TO: Balance Shaft delete

On a more serious note, thanks to the OP for this "How To BSD" thread! Good stuff. Been thinking about doing this.... still thinking, lol.
 
Geez, the Noise/Vibration/Harshness (NVH) "engineers" think that any 4cyl larger than 2.0L needs a counterbalaner setup to reduce NVH. If there is a 4cyl honduh larger than 2.0, it will have a balance shaft....

So a prelude 2.2 vtec has them? I dont know Just asking. I know Honda has some tight tolerances on there motors thats about it :(

Yes..... Pretty much ALL Honduh engines have balance shafts to allow them to run so "smoothly".....

The presence of a balance shaft has NOTHING to do with the "tolerances" in the engine design/assembly and EVERYTHING to do with consumer perceptions of "quality" as it relates to smooth, silent running of the engine. This is also the primary reason why so many cars now have the plastic "covers" over the engines, to reduce engine noise heard by the idiot consumer.

I just figured it would also help the reliability. I mean if your motors vibrating does this not cause undue stress to the internals?

just wondering

pfft no, vibration never causes any kind of fatigue failures in anything...ever. why would you ever think that?

In some cases, especially on smaller displacement engines, the added weight tied to the rotating mass is more stress than small vibrations the engine might have.

This is really old technology and as casting, forging, and machining procedures (and materials) have improved over time it is less and less of an issue.

I think Mr. Tesla would disagree with that. A very small weight vibrating at the right frequency can have a pretty big effect.

Given the scope of a small displacement engine and understanding its environment, even Tesla would have acknowledged the balance shaft's limitations related to the application.

Let's keep this thread clean and not go off-topic with chit-chat.

Please explain to me how its completely off topic. We were talking about how the extra vibrations from removings the balance shaft might/can cause extra wear and tear on the engine. Thus leading to a proven example how a vibration at the right frequency can have an affect on the engine via a link on the Tesla's theory which is still related to the fact that removing the balance shaft might do undo harm to the engine.

A how-to thread should be more technical, and address the original issue or installation, not a place for chit-chat because you don't know where else to put it. While vibrations is the only thing that you're talking about with relevance to the original topic, the rest is BS chatter.

That way, when someone wants to consider/do this mod, they don't have to sift through 10 pages of useless s***, and can see any questions that might arise after the OP posted the thread.

No, this "balancer" has no positive effects on reliability. In fact, in modified, high output engines, it places undue axial loads on the crankshaft thrust bearing and can be detrimental to reliability. Most other OEMs use external belts or internal chains to drive the balancer shaft.

I don't know how many times I need to post it, but ALL balancer shafts in consumer cars are solely for passenger comfort/perception. Maybe it would help those ignorant souls to do an web search for balance shaft...
 
One question from me i would like answered by someone with knowledge on this topic. comfort out of the way. If i plan on having a reliable 350awhp ms6, would i be better off with a BS or a Windage tray/baffle?
 
Take it out, Put in the F2 Mazda BS Delete. go with PTP's windage tray. enjoy 7 quarts of oil and not blowing cylinder 3. call it a day.:)

I'm not sure by how your question is worded, but I recommend the F2 BSDelete for sure and I prefer the F2 tray, but either is better than none with the BSD.

Where can I find the F2 BSDelete kit with the F2 windage tray and how much is it. Also this takes 7 Quarts of oil after removed correct?
