lol intresting subject!!!!!!!! i would love this a very expensive consumable tho not sure how long it lasts tho....jaxx?
It really depends on how much you use it and how big the jets are.
Raptor has made a decent observation saying it will last 4minutes in total, which i can quite agree with.
Doesnt sound much, but if you use a progressive controlller and only have it activate at Wide Open Throttle (WOT), and only have it switched on when really necessary, such as for racing or out for a blast, rather than the drive to work. Then you should find a 10lb bottle holds out well for a month, maybe 2 also depending on your driving style.
Of course a pure race session, such as at Santa Pod will probably see you empty the bottle in a day
Remembering back when i used it i ran 25bhp jets on a Yaris T-Sport (1.5l) and i used 2 tanks in one week at a cost of about 35ish quid i think... but it was a novelty at first!
After it had initially worn off, i was using a tank every 3-4 weeks i think. I never went higher with the jets.
Then i sold the kit to my mate who had a V8 Range Rover, so with it being a big dopey lump, we worked the kit up to the the 75bhp jets, and he was easily polishing off a 10lb tank in less than a fortnight on moderate use.
Im quite intregued to use it on the Clio in future, as to start with you have a nice cast manifold with easy mounting for a direct port kit, and i would use only small jets (25-30) with a progressive controller, that went from 25% to 100% between 3000rpm up to the redline.
I think that would nicely add to the grin factor of the car, without having to get too concerned about damaging anything or emptying the bottle too fast.
