Sproket and tires

[WOOSAB]

My turbo should be finished in the next week or two. What combination of sproket and chains are you guys running on the street. I'm at a 4 inch extension and should be pushing 300 hp at wheel on my rcc tubo. This bike will mostly be used for street riding and the occasional roll on race... I was thinking 18/43 or 19/43 ... It's a 2008 gen2.. tires wise I have always ran Dunlop q2 but never had this much hp to play with so I figured I'd ask..
Thanks in advance

I'm going up to 300 here pretty soon. My tuner said to go 18/42 but its personal pref. I use mine for same reasons as u....Street! I'm rolling 250 in 6" stretch with Shinko's. I like so far
