Spannered for a bloke with a full v&m tuned fzr400. That came with a ram air system. A car brake scoop was shoved through the rad and 2 flexi hoses fed up over the cam cover into the bottom of the airbox. The original air intake was blocked off.
I surmised that from all the leaks and hot air floating about it was a complete pos.
We isolated the rad bars so no hot air was entering from the rad, then insulated the pipes from the motor and finally sealed the airbox feeds with mastic.
Original power runs were 69, after airbox mods and 're jetting as per RMD spec it went to 74.
Also had an R1 with QUB ram air box...........took 2 days of dyno work to get it running right.
Moral of the story is don't foc with it unless you REALLY know what you're doing!
