In my 400 4x4 im running the red primary, 10-58s, violet sec. If I put the S-55s back in it will it over rev? Will it shift out properly? Im running in a 50ft mud bog competition Sat and id like to get more stall out of it. Thanks. [img]i/expressions/face-icon-small-smile.gif[/img]

 

it should be ok

 

I would suggest the HPD light blue primary with the S-55 weights.this will stall to about 4200rpm.

 

Is the lite blue softer than the red?

 

If you look at HPD's chart the light blue is the third from the top.What your engagement right now.
