You´re Uncle Bob on SMJ, right?
Also well known on theturboforums.com for his turbo bikes.
Just a rough guess, but that turbo is probably good to 150 hp or so. A little bigger than I'd want to go unless its an all out race bike
Do you know of any that have useful power ranges lower than the current crop of small frame turbos? I mean even Garrett's tiny GT12 has a sweet spot around 100hp.(as you already know)
