If you are thinking that that title requires zero imagination and probably just spilled from my mouth as useless drivel, well you’d be right. I can’t deny that my words were poorly chosen. In my defense, I said that when I was sent a link to a thread with one wicked fast Forester. When I clicked on the link the only thing my mind could utter was “Holy . Shit.” I know, how educated of me. You try looking at this and not saying something similarly moronic.

What made it even better was the body of the email said simply, “509 horsepower . . . just sayin . . .” Best email I have received in a while.

Well? Were you cool under pressure? Liar.

If you’re unimpressed at the moment, wait for the next part of this post.

I’m not even going to try and summarize the laundry list of things done to this beast, so I’ll post verbatim what was in the thread.

Did you get all of that? Huh? Good because neither did I the first fifteen times I read it. I saw 509hp and Forester and my mind went to mush.

In case you didn’t catch what I meant.

Hubba-Hubba.

Did I mention that this is pretty much a daily and is driven to and from every track day? No? Well that too then.

Did I also mention that the owner and shop are expecting to run 10’s next year? No? Well yeah, that one too.

Holy. Shit.

Thanks for the tip Boost!
