Default Re: Methanol Dominator jetting/ EGT Tuning help

I have pro systems 1050 dominator that came with 200,210 and 220 jets which I'm pretty sure that's way to rich.

I have also installed a egt meter.

I started out with 188 jets made 2 runs with egt of 1348 and 1342.
Changed jets to 192 and made 2 runs and both were 1350.
Then I went down to 184 jets and could only make one run because track was closing, the egt was 1240.


I made 5 run's and it was pretty consistent even with the wind. The last run was slower, 10.21 129 mph compared to 10.18,10.16 130mph 131mph

The question is am I heading in the right direction?

Thanks
The reason the egt was higher with the bigger jets is the fuel was burning in the header causing the high EGT. I still think your EGT is to high and you should keep going. You would benfit from a 950 4150 over the 1050 dominator. The 1050 will work but less fuel will be required, belt drive or electric fuel pump, and what fuel pressure you running ? Did you buy this carb new from pro system ?
