As for performance all i can say is this, i owned an Airflex Turbo which was and still is a great piece of British engineering, however things have moved on in terms of motor design and the new Jag & Storm use these new motors which have kind of abandoned the 3 stage idea and use a totally different turbine similar to a jet engine.
Not starting this again but ....
Your Airflex turbo had a CFM of 330 ( quoted from site )
The Jaguar has a CFM of 296
They both have lift at most of 130"
Nothing there gives the jag a performance advantage ....
Neither really have ' truckmount performance '
A Quadvac ( two in parallel coupled to two in series would approach small TM performance )
Some of the UK builders should really bring out an ETM like this ... and perhaps incorporate
a burner ... the 6.6 would be an ideal for this with its efficient design (lower amp draw ) i'd say we almost could run that on one circuit at 240v . In the states Mytee has just launched a small ETM ...a twin vac , but thats all they or any of the other US ETM builder can manage over there at 120 volts on two cords ... we really should make better use of our superior electricity .
Are you genuinely impressed with the jaguar as it is ... or are you jumping on the hype bandwagon
to flog zetas to Jag owners ...
