blower hat

I'm about to buy a blower hat for my dragster , 421 c.i BAE motor , 14-71 Kobelco K-11 . Can somebody tell me , if i can see any difference in performance between these hats
: New Enderle B & U 5 9/16 , Don Gerardot CFR serie , use carbonfiber type ,
also considering price difference : Enderle $ 1200.00 (bare) Gerardot $ 1500.00 , use carbon fiber $ 2500.00-3000.00 what do you think is the best buy to do.
Thanks Claude

 

I have one of the Enderle Big Ugly hats like you are talking about. For the money you cant beat it. The biggest drawback is the glare off of it since its polished, I may have it powdercoated this winter. Got mine from JR. at RBS, he'll hook you up!
