I have changed the gearing on several 2008-10 Vipers lately and the results have been very positive. On the 2010 model they changed 5th gear to make it more usable. I have been changing 5th and 6th gear, thus putting them closer to each other. I have been pleasantly surprised how much more usable the 5th and 6th gears are. You can actually stay in 6th gear down to 50mph and still have enough power to accelerate and pass someone if you want to.

For those of you who have 2008-2010 Vipers or those who have fitted the later T6060 to your earlier year model viper. There are some close ratio 5th ad 6th (.80 and .63) gear sets available. This allows you to reach top speed in 6th instead of 5th and makes 6th gear much more user friendly. This change makes the upper gears more responsive, putting the engine in the better part of the torque range.

For those with the later T6060 (2009-10) that has the .80 5th gear, you can get just the lower 6th gear.

We can do the same for the earlier Viper trnsmissions as well, but its harder to get the parts.

I have triple synchro .89 and .75 gears in my Gforce trans.  Top speed with 26" tires is 196mph and with 28" tires redline is at 215mph

The stock gears suck and 5th is 195/215mph at the track.  The car that improves the most is the Paxton cars because the OD gears drop the rpm way too low at shifts and lose too much power/boost ...

Agree completely. I was quite happy with the performance increase in the 300 miles I got before the engine blew  :driving:

Almost time for a gear change to my Roe blown Viper.  With a better 5th and 6th I can beat top dollar race cars with my slower Viper too ...  Long live the street car!

You were planning to change the tranny in your TT weren't you? Why not put the Gforce in your sapphire?

Too much money to get a strionger tranny that the GForce so ...

I think I'll plan to buy a 6060, upgrade the od gears and then use that to do my (low power setting) land speed runs then instal that into my Sapphire GTS.

Apparently the 6060s can take a couple runs at 1000hp before they bust ...   I'll add the oilpump system to it for the highspeed runs probably

Back to original plan to use the GForce T56.  GForce does build a race T6060, but it's a 6060 that's been modified to hold the GF T56 racing guts.  Strongest made normal type tranny and only about $7000

What type of clutch and flywheel is required for that setup?
I have to upgrade my brand new spec stg 3 clutch and flywheel for once my engine is back together. It has 300 miles on it, not quite even broken in.
What is your recommendation for what I should run?

I have a chromemoly flywheel and a $3400 dual disc Macleod clutch but it has massive pedal pressure.  Dan at DC Performance had a used one that could be rebuilt to your specs for about $1500 or buy one of the new triple disc clutches.

What will I actually "need"? This clutch I have now (spec stage 3) is rated for 950 lb-ft. That will be pretty borderline but maybe last the whole summer?
Why go dual or triple disk vs what I have now? I'm new to 6 speeds, sorry for the noooob questions.

You have the Spec 3 right?  It's a bit less than the Spec 3+ that Joel put into his TT.  His started slipping at over 1000whp so yours won't last.  They make several twin disc units that work great but none of the decent ones are cheap.  Can Cragin's is the cheapest and would be custom built to specs.  His is a $3000+ US clutch (after rebuild) if he still has it.  Once you get past 1000whp you're into the 200mph below 10 sec quarter mile catagory and you're risking your legs to a cheap clutch.  Most of them do slip instead of blowing up though.  I just purchased a scattershield for my TT.  Required in most competitions and definitely n the faster classes and events.  PIA at $860 but no choice on the TT.  That car is also into the new tires, full cage and 2 year seat belts  SFI axles, loops, etc.
