Norvels have a large venturi and work best using pressure if not a bladder would be an option.
They do just fine on the bench with no pressure but in the end up in the air running
around you will want a good steady fuel flow. Of course if the tank is in the sweet
spot and the feed line is short you may get away with it with a tad rich setting.
The Norvel .074 is robust and is one of the best in its class the TD .09 would be a step up.
Your lil delta is going to haul arse and may really allow some unloading above expectations.
I have been testing a Vertigo .07 on a tuned pipe 35.5in span plane 140sq. in. 16.5oz
5x5E / 20.43k / 120w/ 16.1oz static / 24.94k / 118.1 mph
4.75x4.75EC / 22.86k / 134w / 16.7oz static / 26.64k / 119.84 mph
