The problem you will find is that you have to remove the passenger side fan when you install the FM. So if you are like a lot of people that have wired them to both come on with the drivers fan you loose 1/2 the fan capacity.
I had SOME cooling probelms with mine wehn I installed it, and solved it with Tony's dual Spal fans. They pull a LOT of air and sound like leaf blowers when they are both going.
With both of 'em running I can start a run at 150*-160*, end the run at around 190*, turn the fans on on the return road, and be back to around 170* by the time I reach the pits.
My advise is if you do a lot of street driving, but the fans and install them when you do the FM.
HTH!!!!
