Water injection and intercooler

[fstbusa]

if you get it tuned right it should survive just fine at 7 lbs with stock compression if you're not doing many top end runs.  I've been running 7lbs with water inj and stock compression for 4 yrs and haven't had a hiccup yet.  Tuned by motorhead.  If I ever plan to do top end runs I will put c-16 in it.

Have u done  a dyno run like before or after? Does the the 6lb -8lbs get you 265 -280 range I'm really just looking for  a little edge not  a pure racebike that hp range sounds sweet. Been dreaming of a turbo since I got the bike.

the 0.5 bar spring which is approx 7.25lbs yielded 270hp with no water spraying. With water spraying it was like 263hp.

Methanol injection is another option, used to cool the intake charge as well. My unit is programmed to kick in at 6 lbs of boost and I check it every other fill-up. I use HEET which is 99.9% methanol and sold at any car parts shop.1
