As other posters have written, it's a gear issue. 6th gear is not useful for anything except for increasing gas mileage on the highway. From a performance standpoint, the Viper as it comes from the factory really has a 5 speed transmission. 6th gear is just too high. Almost no amount of...
Check your fuses. A blown fuse can cause the reverse lockout solenoid to not function. Lots of folks have this issue after a header install (melted insulation on wires, causes short, causes blown fuse, causes solenoid to not work.) Don't know if you've got headers or not, but check the fuses...
Tilton flywheel is lightest you can get.
Not cheap, however, and you've got to replace the stock clutch with a carbon/carbon Tilton clutch.
Crazy free-revving.

Will jumpering the airbag sensor disable or interfere with the functioning of the airbags? I assume that a similar workaround would be required on a 2008 which by the way now has multi-stage airbag sensors in the seats (for male, female, child).

If you do it correctly, then...
I looked into this a while back.
You're likely going to have to get custom made seat brackets.
After a lot of research, the lightest weight seats that I could find that still had an adjustable recline feature were the Cobra Misano (full carbon)
I need/want reclining adjustment, because...
Yes, that is with all the mods. It has a little different sound than others I've heard. I've taken a lot of rotating mass out of the engine and driveline (30 pounds for the crankshaft alone) so the rpms rise (and fall) really quickly. Gives it a bit more "bark" than most.
I've run the standing mile a bunch of times at the Sandhills Open Road Challenge in Nebraska.
158-162 is the range for stock Vipers (Gen II or Gen III)
Maybe a difference in altitude accounts for the extra speed in the Motor Trend test.
They are the SSR wheels that John B at Partsrack sells. "Comp H" I believe. I did weigh them, but it was a while back. Can't remember exactly what they weighed, but I think I saved a hair over 22lbs per rear wheel/tire over stock, and almost 20 pounds per front wheel/tire over stock.
18x13...
Some things I did to my car to cut weight:
Custom billet crankshaft (29 pounds lighter than stock)
Lightweight pistons, rods, etc.
Corsa exhaust with crossover delete
Carbon fiber drive shaft;
Tilton carbon/carbon clutch with lightweight flywheel
SSR 18 inch wheels
Light weight stereo...
No. Think way back to high school physics.
Greater rotational mass would require additional time to get up to speed assuming the power remains constant. Once up to speed, however, it does not require any additional energy to keep it moving.
Why would a change in rotating mass result in better dyno numbers?
Thinking of the physics involved, I can't think why that would be the case.
I don't believe that going to lighter wheels/brakes will change your hp or tq numbers.
It could change your real world acceleration numbers, but...
