Go on then mate what are the actual cfm figures ? I am baffled, I thought a Scorpion produced 325 cfm ? not sure what two 6.6 motors actually produce but it must be less ?
Stuart , CFM is difficult to measure accurately so i wouldn't worry too much about 10 or 20 differences here and there , its only when they claim figures like 370 for the 6.6 jag on CT tht it get ridiculous .
The original Scorpion had quite poor very narrow internal plumbing so this didnt make the best of three three stages imo , if you ever used it in two vac mode this could be demonstrated as performance was quite poor with out the third vac , this plumbing was carried over from the American Recoil where narrow plumbing was used to throttle the vacs in order to reduce amp draw , but not really needed in the UK . So yours may have revised plumbing since you had it as a special order .
Your scorpion should be producing about 300cfm and 135" lift .
A 6.6 Jag should have around 280cfm and 130" lift
the 8.4 jag should have about 295cfm and 147" lift
In series the 8.4s have about 145cfm and 235" lift , i believe Extracta are using them like that in the mythical new Turbo version .
