Freestyle 900cc 400hp 2-stroke

[CARBONX2]

Found this in the Bikeman Performance Catalog for snowmobiles. Looks like an 800etec bored to 900 with a turbo

not a 800 e-tech. since skidoo has the e-tech
this is for an fuel injected arctic cat.

my mistake
A turbo at the end of a pfp pipe could work in similar fashion
