I have the 3.55 10r80 in my GT Performance Pack, I've hit 155mph and 156mph on a long straight stretch 2 different days. it can easily do it, unfortunately as soon as you hit the wall, you can feel the computer cut the power to avoid going over the governor.
Except the manual transmission is very tall, and 4.09 would be more fun for sure. I'd think the car would still do 155, but even if it were lower, it'll be way more fun at all the other speeds. Alas, I'm running 3.72 still.
The difference between 3.55 and 3.73 is only about 6% which might make a difference on the track but I am not sure you would notice it in day to day driving. Personally I am not sure that high ratio rear ends is the way to go. The A10 will skip gears indicating the gears are too close together and a lower rear end might be better. My 4 speed 82 transmission was really spaced out but there are advantages remain in first gear as long as possible as you retain the higher torque as long as possible. My dad used to say the first person who shifted would lose the race. Probably true unless you blow the engine. The 82 would go to around 45 miles per hour in first and close to 90 in second. Yes we have far better today but that car could still smoke the tires off the line. Don't believe me? Read the article that I saw before I purchased the car. Remember, in its day this was top of the line and many police department used it as a pursuit car.
That can't be right. All three transmission have a final gear between .62 and .64 so you would expect the top speed to be nearly the same. Either the rev limiter is in place for the tr-3160 or you are using 5th gear instead of 6th gear. As a double check 2,000 RPM is about 70 miles per hour in my car. There isn't that much difference in the rear end.
i just checked and you are right, somehow i had the TR-3160's 6th gear in the simulator set to 0.829:1. the corrected test shows it runs out of steam at ~210mph, 6th @7000rpm
