Hey I wanted to post this and see what some of the other tuners think. I have heard and I was thinking of reinstalling the pair valve system and using it as a crank case vaccum pump. I have heard that this mod will yield good HP numbers by relieving the crankcase pressure's.
Only thing is you need to make sure that if you do this mod you need to undo it while tuning on the dyno, then once you get it tuned then hook it up since it will throw off the O2 sensore by getting oil fumes into the exhaust.
Basically you connect the large tube from the pair vlave to the crank case breather tube and then plug the airbox ports off. If anyone has ever tried this with good results post up here and if not I may do this mod and dyno back to back with the results.
