Default who is actually running without balance shafts?

what displacement motor?

how many miles?

street or race only use?

observations?

im not especially interested in spending more quality time with my TiG fixing cracks...

real world experience would be appreciated.

Lots of guys dont use them... TongG I think does not. I looked at this a while back. They are a Mitsubishi design, dont dont make too much vibration difference if I remember correctly from people comments.

definitely a mistu design...the whole motor looks like they cribbed it from mitsu...

i appreciate the post...i know the diamond star guys get rid of em, but they are running smaller displacement shorter stroke stuff than we are.

still hoping for other voices.

thanks

What is involved in removing them? Engine rev quicker? What are the gains?

Can't give you the answer you need, but I do have a Gomes delete kit in front of me too. Nice kit! I'll be putting it in a race motor, who cares how loud and obnxious those things are?

What does the delete kit give you? Who supplies them? Cost?

No balance shafts here..

Definitely not as smooth as stock here. 2.5L, Carillo Rods, lightened crank, aluminum flywheel.

Be prepared to locktight/locknut/lockwasher everything bolted to the side of the engine including the bellhousing.

5lbs each is my guess. I pulled them off the block, but I didn't actually weigh them.

Thats heaps! Whats the deal with the delete kit? Smooth ride Tony? Benefits? Other than removing just another thing that can go wrong... Down side?

Don't do it unless you have lightened your reciprocating mass. It won't help, ie aluminum flywheel knife edged lightened crank, etc...

So how do you get smooth as stock and certainly not in another? What are the differences between that would influence it?
