The Ruf front cooler package worked extremely well for me with a 550 hp turbo application on the track.
Its a proven design, it bolts on and fits without hassle.
Since the Ruf valence is mounted flush, it leaves more room for air flow.
I fitted mine with the Ruf in series with the stock front cooler and temps never got above 200 deg F even on the hottest track days.
I bought this same combination for my current project, but have since changed my plans...... again.
I am building a "Yellow Bird" clone for the street with about 450 hp. I have fitted two factory 87 911C type coolers instead, to allow room for a larger A/C condenser in the middle.
I can post some photos if anyone is interested.
