Title: RoJett port timing
Post by: steven yampolsky on June 10, 2007, 09:11:30 PM

What is the port timing for the RoJett's? I am trying to get a pipe length for a RoJett51 from Randy's pipe chart.

Hi Steven

You cannot set it by what my chart says for PAs  because  the timings on Jett engines have been differant.
Best thing is to check your particular motor your self, or  call Jett  and  ask, if you do neither  use  the  chart  at the  145 degree setting,

Regards
Randy
