My puzzi 100 quadvac , still not finished

Someone here is fitting two accessory planet 6.6 to an older machine , perhaps they will post re fitting etc
For fitting two or three in parallel you should need no tank mods , as lift will be no greater than that of one vac on its own .
The 6.6 , even on paper has less lift than a standard 5.7 three stage .. 131" compared to 137" . In reality Jan Sullins has measured lift at around at around 115-120 for the 6.6 . The reason CA or solutions wont show lift figures is because id say many believe figure on the CA site ..ie 265" lift for two ... ( but that is for a series setup which doesn't relate to the Jag in any way ) also it would likely be less than the scorpion will many wouldn't be thrilled about either .
( my opinion ... feel free to disagree or argue the above points anyone

)
EDIT - (since typing this I notice Cross american had now amended the Jaguar lift figure on its site to 131" )
Yes two on the one cord should work well , four in series/parrell should make for a powerfull etm ... it draws about 7.5 amps (measured) which will decrease a bit in use ... and a pumptec draws ony one or two amps so id stick that on too , use 2.5mm cord (20 amp )
6.6 is a little cheaper on accessory planets website ..

... they are a bit expensive , but no more than some charge for a 7.2 here
