As title does anybody know if it fits and works on a r1 5pw? 🤷‍♂️Where’s marcaztls when you need him ?

Off the top of my head I'd say it's unlikely to fit, the 4xv uses carbs and the 5pw is fuel injected, a quick look at both the 4xv and the 5pw airboxes on fleabay shows that they're differently shaped and as far as I'm aware they also have different frames. 

Is there any particular reason you want to go down the ram air route? Apparently setting up a 4xv with one is a bitch of a job and I can't imagine that it'll be that much different on the 5pw.

Never heard of anyone doing it. That's not to say it can't be done. 

5pw frame is similar to 4xv/5jj. They share many common parts. It was more about chassis geometry than anything else. They went for evolution rather than evolution. 

I'd go for a decent pipe, air filter and power commander. That should see you near 150bhp at the wheel. Mine is 148. Or was last time in the dyno. 

A bit of head work and cams should get you maybe near 160. 

Decent 4xv's were up over 170bhp, the V&M bikes even more apparently so big numbers must be possible.

Get hold of a copy of April 2013 PB, it has an article on the Virgin bikes.

They made their own air scoop.

My mates 2000 bike was 191hp but that was bored / stroked / ram aired by EDR in the states.

I think mine deserves a bit of a lift.

I've got an Arrow full system to go on.  It's in bits again at the minute for another gearbox issue. I reckon it'd be worth doing something to it while it's in component form!

My V and M built 98 was 179 rwhp but on flatslides. Same engine was 160 with properly set up ram air. On the same dyno Glen Richards superstock R1 was 169 but was a far newer model.
