Ok...
Just one more thing..
What is the difference between a 6 piece and a 7 piece balance shaft elimination kit???
Just ordering through JAM.

maybe they meant the differance between 6 bolt or 7 bolt crank?
Also, I think it is a good idea to run a good fluid damper pulley. I have seen a crank come out of a good running stock block evo magnafluxed with a hairline crack so we were lucky to decide to build the engine at that time instead of run it more on the track!

I've had motors w/ and w/o B shafts. For a DD, I perfer b/s. It just makes the car easier to drive.

FYI the balanced shaft was developed by mitsubishi to balance an inline 4 cylinder engine. it is not needed by inline 6 or V6 engines. Porsche thought that it is a great idea and uses it in their engines too.

Few question i would like to ask;
How much hp were you putting out with balance shaft???
Did you built your motor keeping Balance shaft???
Did you had any sort of failure with keeping the balance shaft????

Do some research? Wow. I asked if you refering to a balance shaft itself failing, because thats what it sounded like in the prior post. I ask because it seemed ridiculous to me to think the shaft itself would fail.

Man, more and more people with attitude problems. And when i refered to bearing failure, I was refering to the same bearings you were, smart guy.

And again I ask, where are all these balance shaft failures documented?

Hey bud, I was seriously NOT giving you an attitude.
I think it came off wrong with my typing. Sorry

Alot of companies use balance shafts, I have yet to see a well arranged argument that is valid for keeping them on a well balanced assembly.
I guess when the failure occurs the lesson will be learned.
They have been removed for almost 2 decades now. On a daily driven vehicle that will not see the same stresses as a higher output engine, I can see why it may not be as much of a concern. But that still doesn't mean that it cannot randomly fail.
As far as the detonation point made that causes rod bearing failure.....
Its a stretch to say that detonation of that magnitude will not destroy the evo's two piece piston first. At least a ring land, something. Now a very high tensile load, detonation and or over boost can cause more damage to the conrod bearing over the piston surface. But for a prolonged period. At least 20 passes at a drag strip with the same result will weaken the assembly to that point.

Also, I totaly agree with incorporating a fluidampner
