What gearing do you like for street use?
300hp with a quick spooling turbo

I have a new from last year 42 rear and can get a good deal on a new 19 front

so 19/42 is close to 18/40

 thumbs  up

Anything more aggressive than that and it'll be hard to put the power to the ground.

I run 18/44 in mine but it spins on the street badly at damn near any speed....probly 18/40 would be good as others have said.

I'm going to run the same gearing with 8psi on the turbo as I was na....which is 1 tooth up from stock in back. I'm also staying stock wheelbase and height lol. This is strictly a street ridden bike tho.....no racing, and I'm at about 4500ft up, so I'm curious to see the results of this set-up  laughing7

That means your going to run 17-41? if so and your running a stage 1 kit with 6-7lbs of boost, there is no way your going to keep it on the ground, in 1st, 2nd, 3rd, and maybe 4th when boost hits its going up, unless your a really big guy and sitting on the tank

I agree Dave...more than likely it'll be over the top  laughing7 But at my elevation I'm already going to be losing a smidge over 2 psi of boost....so it'll be real close to 6. When I get her finished up and running I'll post up my results  thumbs  up I have no experience with a turbo bike like this so I have no idea what its gonna do........I will be very careful tho....and more than likely end up with extensions and taller gearing I imagine lol
