The 2058 pipe is amazing to use with the Orion engines. David have increased his mileage alot with this and 7.0 Ventuty on both the 3 and 7 port engines.

In sweden he normaly have 10:00 - 11:30 runningtime, and we always go for 9:00 refueling time .. often as the only driver.

Then ofcause the gas finger is very important, but before the 2058 he never could go on 9 minutes with the same engines.
