Texas Mile Supercharged Nitrous Aprilia Practice Runs

This series of videos was shot during our nitrous dial in on Saturday, some runs are with the bottle and some runs are without the bottle due to learning the little trials and tribulations of a new nitrous system. Mainly I added all these together for audio and visual enjoyment of the Team Punisher/AF1 Racing Aprilia V990 LSR in action. This is one fine sounding bike so turn up the volume! Sorry for the shaky video, I was too busy actually working on the bike to bother with tripods and monopods and such!

The engine in this beast is the masterpiece. 100mm custom forged CP pistons are being flung up and down by Carrillo custom Steel rods, propelled by a Falicon supercrank all spinning in fresh and correctly sized new OEM plain bearings. The valve springs are beefed up but stock valves slide back and forth resting on Beryllium Copper valve seat, their push comes from custom web grinds on the intake side with a little less durations than stock and longer duration high lift intake cams on the exhaust side. Spent gases are exhaled through a one-off Smalt-Moto exhaust system, when in LSR configuration through two dump pipes with no muffling. The intake side is handled by a Rotrex C15-60 trim supercharger blowing into a modified spoon valley plenum which carries the injectors for the Labonte Water/Methanol intercooling system. VP MS109 gasoline is fired out from 750cc injectors after being pushed through the a/n delivery system by a Walbro 255 pump and all of this magic is controlled by an "Unleashed" Megasquirt based O.S. sending it's directions and getting it's inputs from a hybrid Suzuki GSXR wiring/Aprilia RSVR wiring harness....and so much more....3.5 years in the making, 192.8 is our current top speed!
