Will I have to change my clutching ??

[doornenbal]

I have a 2009 M8 OVS race gas turbo, 162 Power claw track, timbersled skid... etc I have been running between 10-13 lbs depending on the weather and elevation on 111.

This sled is dialed right in, clutching is spot on and throttle response awsome. Only thing that I want to change is the track. I was hoping to put on the 3inch but I do not want to be messing with my clutching and fuel etc because the sled runs so good, I figure I could put the 2.5 and make no changes....

Reasson I am a bit nervous is I tried to tune the sled to run slightly higher boost (14-15lbs) and I could not get it to run right... Lots of burbles and missing, sled was not the same at all. Put the boost back to 11 lbs ... perfection!!

Any help from people who have made the switch would be great!!

If you go to the 2.5 you may not have to change anything, the 3 inch might be a different story but I would look at a gearing change for that if anything.

what gearing would you use?? And is the 3inch that much of a difference to the 2.5?
