The Vortech kit comes with a billet aluminum mounting bracket that holds the blower and all the drive pulleys for it. Since space is tight and the blower cannot be mounted very far to the front of the car and the blower drives from the rear, power must be taken from the crank. From the crank the power is transferred to a short intermediate shaft that goes through the mounting bracket. From the intermediate shaft the power goes to the blower transmission via a short belt on the rear side of the mounting bracket.
Since the blower is always coupled to the engine, at light throttle, closed throttle and at cruising speed, this bypass valve opens and dumps excessive air overboard. This reduces parasitic losses as the blower is basically freewheeling when the bypass valve is open. The Mass Airflow Meter is positioned after the valve so dumping excessive air does not mess things up, the MAF only reads what’s going into the engine.
When the throttle is opened and manifold vacuum drops, the bypass valve closes and the blower can now make boost. The valve is large and has minimal restriction so the blower will have minimal drag on the crank when it is not needed.
The kit comes with a large washable and reusable K&N filter. The filter clamps right on the blower inlet.
Since extra power makes more heat, we decided to upgrade our radiator with a Koyo racing radiator. The Koyo radiator has an all aluminum TIG welded construction which is much stronger than the plastic stock radiator and can run at higher pressure. The Koyo uses their new V core, a 36mm core designed for applications with minimal clearance. With the Vortech, clearance is very, very tight and we felt that this was one of the only performance radiators that would have a chance of fitting. The V core is very efficient despite being pretty thin and was over twice the thickness of the stock radiator.
Like all Koyos, this radiator has all the correct mounting locations for all of the stock stuff and easily drops right in. The stock fans and shrouds install easily. The filler neck is machined from solid stock including the tabs that retain the radiator cap for strength.
