Combines N5 what should the boost be at

[Hyper_Harvest_II]

81' and prior N5's with the Roosa-Master injection pump usually run between 19-21 lbs..If your N5 has the AMBAC injection pump then your boost pressure will be lower somewhere around 15-18 lbs.. Now,the above can be considerably different if somebody has tweaked the fuel settings. Hope this helps, Hyper Harvest II

THanks for the info. TOday I ran in 2nd with the hydro all theway and in150 bushel corn the boost would rise to 18,19 sometimes but inthe thinner corn about 15. I'll check on what kind of pump but it sounds like an ambac. THanks for the info. thanks,lawghawg
