flywilly,

jettengineering.com is the web site. The BSE engines page has most of the 1.20L info on it.

Headers.... I believe Johnson is making those for Dub. They are available in a few different rise sizes.

Pumps...... Dub has in the past utilized the perry pumps in a few applications. I've tried them too. In most cases, they work ok. In some cases, they were not quite as effective (mainly on the higher rpm engines). That was using them as "direct supply" pumps. In some cases, we found better results simply running a 2oz tank as a header tank right behind the firewall, which was fed by a tank over the CG.

More recently I have been experimenting with the iron bay regulator and fully pressurized system, and also gathering some info using the perry pump with a return-loop system (works more like a fuel pressure regulator) similar to what the helicopter guys use. Results are promising, but I don't have enough data and flight time to claim a victory quite yet. Cold weather is setting in... not sure how much time I will get in testing over the winter.

As Dub likes to say... everything works once in a row. When you can duplicate the results consistantly a great number of times, then you are on to something. So I tend to error on the side of caution before making any official recommendations

If you wish to get more specific information on Dub's pump tests/experience on the 1.20, drop him a note directly at [email protected] and he will glady reply.
