I can't say I'm a nos expert but have used it to qualify for some quick shows where we were out classed.That being said it is allot of extra work bottle heaters,filling bottles,changing bottles,getting the tuneup to do what you want,getting the chassis to except it.making sure it is not going to eat the rings ect ect ect.Any fool can bolt on a kit and go kind of fast is a true statement but to do it on a regular basis and not smash anything and go rounds is something very different.

All that being said I don't run it anymore because I don't have the time it requires to do it correctly and just ain't interested in the class. I do love to watch them run though and HELL YES THEY DO IMPRESS ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
