Question:

What the heck does this blanket thing look like? How the heck am I supposed to build or where do I get one of these new blankets for my gearbox? Does it have to be sfi approved ? If so, what spec does it have to be?

Answer:

No, it does not have to be SFI approved, but it must be built by a recognized blanket maker and you will need a receipt that states the date it was made, material and manufacture of the blanket.  Below I have listed a couple of companies that have already contacted NTPA and are ready to build a blanket for the multi-engine gearboxes.

Remember, when you order one you will need to know the circumference and width of your gearbox and will have to provide the builder with all the proper dimensions in order to fit the blanket correctly.

Companies that have agreed to build them so far:

Gerardot Performance in Indiana,   
260-623-3048

Taylor Motorsports Products in California,
714 630-7850 Tech Line
800 320-2988 Order Line
714 632-7897 Fax Line

I have posted a picture below of the blanket. I believe that Gerardot built it for this tractor.
