yes I do. Just about done
2006 with twins.
PLEASE post photos of the build if you did it yourself. The work you do on your bikes, is second to none, can't imagine what you cooked up with your own car.
As per your original question, I would recommend you go with a TR-6060, and have Donato Engineering do the revised 5th/6th gear ratios. We have 2 local TT Viper's that had G-Force transmissions, and I believe they went through a couple G-Force builds before going to a stock T-56. That lasted for a bit, but the TR-6060 is going to be your best choice if you want it to live a while. The .80 5th gear will definitely keep you on boil compared to the stock .74. If you don't want to dig into your new transmission, get a 2010 Viper TR-6060 that comes with the .80 5th gear.
My stock 5th gear ratio makes me want to bang my head on a wall. Nothing like pulling like a freight train to 160mph, and then bogging in 5th gear
If you've read around a bit, you know the .74 to .80 5th gear change in the stock 2010 allows the Viper to reach it's top speed 14 seconds faster, with no other modifications! I'm taking a wild guess that you are looking to enter in a top speed or standing mile competition with the car?
