RE: Gear ratio
Here are some 6th Gear numbers. I guess I get my 2K RPM range at 70 MPH in 6th Gear with a 4:10 gear ratio.

RE: Gear ratio
For drag strip and automatic is the way to go, but I plan to do more with road handling hence I prefer a manual tranny.
"Dave Smith of Factory Five Racing said there are numerous reasons to install a standard transmission in your kit car: "A Cobra replica with a manual transmission has a better resale value because that is how the original car was configured. Therefore, typically, buyers looking for a Cobra replica will look for a stick shift, but if you are going to do hard-core drag racing, you cannot beat an automatic transmission. For road racing and autocrossing, I believe you need to have a manual transmission. For driving on the street, it is personal preference. I prefer the manual trans because it is more period-correct. An automatic in your daily driver may be more convenient, but banging a four-speed is a lot more fun for me." "
For road handling I believe manual is the way to go. Kit car builders who understand that you put 15 to 20 percent more power to the ground in a manual than in an automatic, as there is very little parasitic loss in a manual trans system. Heat is parasitic loss, plus you link power to the ground instantly in mechanical coupling (manual) as opposed to hydraulic coupling (automatic). Another key point is that manual transmissions can be 99 pounds lighter than an automatic, and some automatic systems weigh as much as 200 pounds more.
Every 100lbs can be .1 seconds off of ET times

RE: Gear ratio
while i agree that the manual is more efficient, your numbers are bit off...a manual trans is not 15 to 20 percent more efficient based on whp...unless im unclear on what numbers youre using...ive seen an MTX car dyno 5-8 percent better based on bhp..but not 20%
and in the event of some cars, the auto is better for the track, especially older cars. old MTXs were crude and inefficient...ive seen someone take a high 12 second cuda, and swap in a 4 speed, and slow the car down quite a bit. while its more efficient than the 727, it isnt as fluid, and time is lost in shifting...hell, even the fastest LS1 based GM cars have automatics...i know a guy who has a built 02 camaro, and when he went from the mtx to a built atx, he went from 12.1s to 11.80s...

Your 12 second Cuda is obviously for the 1/4 mile drag strip and I am talking about talking the road. Automatics are very consistent for the drag strip but if you want to feel the road
you need a manual tranny.

RE: Gear ratio
I think Dodge will set it up so you will only shift once to get to 60mph. One set up for the automatic and one set up for the 6-speed. They will do this for the 0-60 times that most car mags will test. Just my opinion and we all know what that means.

RE: Gear ratio
What was cool was the older Ford GT40 could hit 93 MPH in 1st gear alone.
No wonder they would win in the quarter mile when they were not racing in Le Mans.
