p { margin: 0; }Michael
i have the Jab 3300 on a 601 XL that was running high EGT's on climb out at WOT.
i finally had to go to a 260 main jet to get them down to manageable temps.
they are now all in the 1200 to 1250 range.
i also had to richen up the needle jet one size to lower cruise EGT's
you might want to try this. it also brought down my CHT's.
Fuel consumption is 5.2 GPH at 2800 RPM
do not archive

Bobby,
I should have mentioned that I'm running a Jabiru 3300A w/ Hyd Lifters which has the new exhaust and induction designs, as well as the new head fin design. I'm also running an AeroCarb instead of the Bing.
Last week I put some monitored engine data on my website, which you can see here...

I haven't gotten the courage yet to get near the spinning prop, as I've gotten that suggestion from some local automotive gearheads.
Thanks for comments!
