The yank solonoids are apparently unreliable in comparision to the Wizards of Nos kits, don't take heat very well and using them progressive controllers shortens there life further still. Also with the Wizards kits you don't need to purge the lines and imo better customer service as they are based in England.
Ran a kit on my old rst and it loved the stuff Will be putting 100 shot in a saph 4x4 once I find a decent one

Using it as a anti-lag would eventually turn out too expensive, better off hooking up the anti-lag on the P8 imo...Gas is great for 1/4's but just as anti-lag I wouldn't bother unless it was something as huge as a GT40.

Lastly I was led to believe gas does'nt like low revs ie below 2500rpm can't remember the reasoning though. Have a look on www.noswizard.com
