I do a lot of road racing with my track evo. I have balance shaft eliminator kit right here in front of me, I have been thinking about having the balance shaft remove. What are you guys thought about it ? remember this is an track/road course evo. So keep it in our remove it ?

 

I'd do it. ya make a little more power. and it takes stress off of the oil pump so it will last longer. which is good since your in the higher rpm's a lot with a track car.

 

I road race and drag race my car as well and I was back and forth about doing it. Really this is the only thing holding us back from spinning real high RPM. I ended up removing the rear shaft and machining the front shaft to a spindle. Essentially is is the same as the one AMS sells for about $300. You simply bring it to a machine shop and have them put it on a lathe and take off the counter weights. It only costs about $40. The stubby shaft has been used for years on DSM's and many evo's run it as well, but I can't recommend it. I have personally seen 2 oil pump falures that were running the stuby shaft. I can not say that it was a direct result of the stubby shaft, but I have my suspicions. I can honestly say that I feel no difference in vibration even with poly engine mounts. The car rev's quicker and I am very happy that I did it. Now I can feel safe when I bring it up to 8500 RPM or higher. Hope this helps.

 

Remove them, they will be one less thing inside your engine that can cause problems, specially for what you use the car

 

If it's a track car I would say remove them. When I was building my motor I was thinking about taking them out. I DD my car to and from work and everywhere else so I decided to keep them in.

 

thanks everyone.
