That's just poor fitment. I've got an APR intercooler and a TyrolSport radiator and mine clears my Neuspeed throttle pipe. Not a mark on it. Maybe your fan is jacked up and out of balance and spins wonky when it goes high speed.
Yea the mishimoto would be 14" for the latger and 12" for the smaller. what makes them even better is they are not exposed so (like ive encountered once without knowing) you wont have to risk the throttle body pipe getting sliced open by the fan.
and yea way more output from these. just did a set on my buddys fox body mustang. used to sit a little over 190 on the gauge at idle and now hangs out around 175/180 at idle.
This does wonders too!
Yea def weird your plastic fan sliced an aluminum pipe, but why the big throttle body?
the hell is going on with your HPFP?
ok i'm getting my head wrapped around it. looks like the mount is fabbed off the intake. what about the lower bolt(s) and how is the high pressure line routed
