your right clarkey, i have wizards system in the lotus but a usa purge kit and the first day the purge got stuck, reason being the american versions use solenoids, and WOS use pulseoids, which are so so much better.
and nice one ray, you have joined the nitrous revolution, where ya having your purges? just had mine re-fitted, shoot about 4ft each side of the windscreen, better to pose at night though,,,,as for c02 purge kits, i found it doesnt work aswell, think its to do with the weather at the moment to be honest.
and as for power increase, you can safetly increase your break by 40% on the cars power (standard output i assume) without and problem, im running around 100bhp jets in the lotus, maybe a little less. but it kicks in 2nd/3rd. i have used it in first but clutch only handled it a couple of times, and i have to try and grab the gearstick b4 it hit 9500rpm (oooppssss)
