IF YOU ARE ORDERING THE BREATHER FOR ANYTHING OTHER THAN AN N54 TEST CLOSE YOUR HOOD CAREFULLY TO ENSURE CLEARANCE IF IT DOES NOT FIT LET US KNOW, AND WE WILL GET YOU A REFUND ONCE THE BREATHER IS RETURNED.
MODEL LIST OF REPORTED CLEARANCE ISSUES: N55 E/F 3 SERIES
The N54 suffers from a weak point in its crankshaft. It has been reported that when increasing the power to the engine, the crank hub can move or spin slightly under an extreme load. This is most apparent under high-rev downshifts or in the case of increased boost pressure which creates more stress on the engines rotating assembly. In order to keep this from happening, the crank bolt must be secured to the hub to keep it from backing off, but this can be a tricky solution since a simple dab of Loctite will not suffice.
Here is an easy, and cost-effective way to secure the situation; The VTT N54 crank bolt capture. This lightweight and durable ring slips over the head of the crank bolt fully encapsulating it, and locks it to the crank hub and eliminating its ability to spin. The VTT-CBC is 100% Billet Aircraft Grade Aluminum, Anodized black to protect it from the elements, and give it a stealth look. What's more is that it weighs only 1.3 Oz's meaning you aren't adding excess mass to the crankshaft which will avoid any imbalance or vibration issues.
While this is not a full fix for all crank hub spinning issues, the engineers at Vargas have found most issues have stemmed from the bolt itself backing out, and this is a great way to keep that from happening. Extremely lightweight at only 1.3 Oz's it adds virtually no weight to the crank which is important for balance and vibration.
