My logical reasons for not allowing Nitrous.....
1) there wont be any classes. if you throw Nawz in the mix, turbo size wont matter. you can have a guy with a 62mm charger spraying Banks amout into the motor and having the same amout of Dyno HP as a 3.0 charger truck on fuel only.
2) tech would be painfully long! Checking turbos is long enough, now you want to go over an entire wet or dry system? Measureing jet sizes, solinoid sizes, and all that will take FOREVER!!!!
3) insurance companies dont like drugs. Its hard enough to get insurance for a pull, and if you say that you are allowing Nitrous in a pull....nobody is going to cover the event!
4)If nitrous is allowed, the rule sheet on that alnoe will be so long that most people wont be able to follow it. The rules in pulling is long eoung, most people dont want more rules.
5) Running fuel only keeps cost down. Its hard enough to build a motor, chassis, and drivetrain to hold fuel only HP that building for fuel and Spary would skyrocket the cost of pulling. Its not like drag racing....we are dragging 3x,xxxlbs down the track with us!
6) Sled pulling is deeply rooted in our coulture. pulling has been around A LOT longer than drag racing, and we have gone this long with out spary and many guys condem the thought of it. Just try telling a Pro Stock tractor driver he needs to spray his tractor!
I guess thats enough for now. Thats just my hunble openion though......
