Excellent Engine Cooling

Posted on Facebook, Samba and other Sites, I have read with interest some negative comments about the Bergmann High Flow Fan Kits.
NO 1: DON'T BUY IT, it's a very poor design. Due to the absence of vanes inside the shroud, the fan just blows the air against the back wall, the air has nowhere to go and overheats the engine.
NO 2: 1+2 cylinder side gets all the cooling air, making that side of the engine run too COLD, 3+4 side gets very little air and makes that side OVERHEAT. Very inefficient design.
NO 3: The fan is so noisy, you can hardly hear yourself talk.
NO 4: I could not believe it, after testing my engine, the alternator and fan took 50 Horsepower away from my engine.

After 16 years in production, over ten thousand kits installed by individual customers, I have NEVER heard such comments from a single customer. Some customers had this kit on their engine for 16 years.

The Alternator-Ring Stand is bolted to the long block, sealing it underneath with the original type paper gaskets and a metal oil deflector plate.
The 3 bolts on the left will fasten the idler pulley bracket to the stand. On the right you see the cut out above the oil dip stick, creating just enough cleareance for pulling the dip stick out of the case.
The center 8mm bolt with washer and locking nut serves as a locating pin, placing the ring in its proper position. Screwing the bolt into the ring's recess hole will prevent the ring from turning to the left or right or push forwards or backwards, FOREVER keeping the serpentine fan belt aligned.

A close-up view of the recess hole drilled into the ring.

I placed the ring on top of the stand (without the alternator and fan), so you can clearly see the proper position, it's functions and how it looks inside the shroud. The CHEVY 110 Amp alternator has a very small diameter. We had to make a new mold with a smaller center ring to accomodate the altermator. This resulted in 22% more airflow. EXCELLENT!!!
The four air directional support posts do exactly that, directing the air flow inside the shroud. Please note that each post has a different angled shape.
NOW LOOK AT THE FOUR POSTS AGAIN.
The posts are exactly spaced 90 degrees apart. As the 12 blade fan turns clockwise the two UPPER POSTS directing air to the one and two cylinder side. The LOWER POSTS are directing air to the three and four cylinder side. Now, if you take a real close look at the four posts, you can see the shape and angle of them, directing air to each cylinder in the firing order of the engine 1-4-3-2.
The 12 blade aluminum fan is of exceptional quality and far more efficient in cooling the engine when compared to the stock $18.00 flimsy metal fan. Also, due to the increased air flow, it will deliver more heat flow into the car during the winter time.
