what do you have launch control set at? and how did you do it? dump the clutch? slip? i mean its different from the stock turbo, curious how you did your launch with a big turbo on stock clutch. did it rip out of the hole? or bog or what?
your name is 900rr, i assume you have a big or know guys with bikes, how does the car hold up with bikes from a roll?
sorry for all the questions

Modded Evo= 477whp/3200lbs = 6.7lb/hp.
Stock 900RR= ~110whp/~400lbs= 3.6lb/hp.

As far as meth usage goes, the meth starts pumping when I hit 8 PSI of boost. Im guessing that for 1 minute of being in boost at 8 PSI or more I use about 1 1/2 gallons of meth. Its hard to have 1 minute of boost time during my average commute or rant around town so its not too costly meth wise. I got 10 gallons of VP Racing M-1 (meth) from AMS when I picked up the car, I think it was about 35-40 bucks for a nice 5 gallon can. I try not to drive in the rain so finally my windshield washer tanks gets some use... 
I think it would be much easier to disable your meth system (pull out the fuse) and then reflash your ecu (use ecuflash) using a race gas map.
This setup is great. The mivec + 50 trim + alky must be heaven.

modded evo = 477 + 3200lbs w/driver and gas = 6.7lb/hp
900rr = 110 whp + 600-650lbs w/driver and gas = 5.4-5.9 lb/hp
driver weight is a huge fraction of the total weight on a bike. if your a fatass, you will go much slower then someone who is a twig.
do some weight reduction on an evo to say, 3000 lbs/wdriver:
6.3 lb/hp at this point it is almost a drivers race. aerodynamics will play a huge part in a high speed race.
^that's what I was going to say 
adding a 200lb driver to the bike changes the p/w by 50% up, whereas even a 350lb driver in an Evo only adds 10%. And that's an even bigger dent out of 110hp than it is out of nearly 500...

Bikes are usually drag limited and have higher top speeds than an Evo so the slight hp/weight advantage over the Evo is more than enough even with an older bike. My CBR weighs 542lbs with me on it and has 173hp to the rear tire (3.13). My Evo weighs 3268 with me in it and has 352awhp (9.28). I know what I choose when I want to go fast.
