I had a similar 2 throttle body setup on my VTX with a 25-50-75hp staged setup. Wet with fuel pump, nitrous and fuel nozzle in same housing. Activated in 3-4-5 gear at 70% throttle, hot at WOT in 3-4-5 gear.
On the VTX it was 89, 108, 136, 154... stock 25, 50, 75 shot, running premium gas, side burner pipe and kn ramair setup with Barnett clutch. 50 and 75 shots caused wheel slipping on dyno in 4th and 5th gear...
its totally awesome to see an air cleaner fly 100 feet in the air not to mention a flame thrower coming out the bottom oil pan when things go wrong.
but it makes a great conversation piece. plus nobody would mess with you they would think you were crazy for putting the nitrous on that 2300!
of course i will not go into the bad stuff.
ok just one i was staged in front of a monster truck (in my rail)when his motor back fired and quit they were behind me and trying to get it started luckily i made my run through the mud bog before they got it started.
when it started no one was in the driver seat and his wife was in front of the truck the truck was wot and in gear it ran over his wife (she was just skinned up a bit) and was going across the arena when the flagman decided to flag the truck to stop it (wasn't a good idea ) but he was saved when the truck went in to the bog and got stuck. good day lot of excitement and no one was hurt.
