Gas Milleage

Pretty important to list the individual transmission ratios too as those effect launch (especially 1st gear ratio) and the rest of the acceleration curve regardless of the rear ratio. 3.31 might be fast on supercharged cars, but FGT owners who upgraded to a lower 3.90 aftermarket ring and pinion love the feel of the car, even with 700 plus rwhp on modded FGTs. Lot more fun to drive on the street and the track.

Having a car with 3.07's is like driving a car with a Powerglide.....might be fast in a straight line but not as much fun as 5 or 6 individual gears to choose from.

I don't think spinning the tires of the rim is fun. I like traction and that is why they all had lower gear ratios. Plus when you say supercharge you have to say well what makes this ratio good for that characteristics? The characteristic of the supercharge is a flat torque curve with mostly steady torque throughout the entire band. Not to mention a lot of torque throughout the band. The viper if I remember correctly and I could be wrong, also has a flat torque curve even though it is an N/A motor. So the 3.31 would help with the traction, gas mileage, etc.

The viper does have a flat TQ curve, basically off-idle up to 5K RPM, where it peaks and then tapers down to 500 and change near the redline. The point of the taller final drive gears is to get the engine into its powerband faster, especially between shifts when you drop revs. There are really no traction issues with the Viper once its already moving and fuel economy is good enough for a car with nearly 700 HP - didn't even think about it when I went to buy mine. The TCS in the Gen 5 really works well for keeping wheelspin under control during hard acceleration.

I much prefer the 3.55 gears over the 3.07 gears in my other Viper. The Gen 5 is easier to drive with the new gear, take-offs are a breeze. With the aluminum flywheel, you need the rpm to keep from bogging, that gear helps a lot. When I put an aluminum flywheel in my '06, it was difficult to get off the line from a red light without wanting to bog. I put 3.33 gears in that car and it takes off much, much better.

On my long road trip, I was filling up the Viper around 250 miles each time. Believe me, those stops were a welcome thing after 3 or so hours. Good to get out and stretch.

Wish bigger tank at least...

Me too 18 to 20 would be great

If it's any consolation my friend's boat has two 275 gallon tanks and burns about 25-30 gallons of diesel per hour if he goes easy. My Yamaha rhino has a 700cc motor and gets 10mpg and the average moving speed during a good ride is about 17mph.
