Not Ranked
Of course, you only need less than 20HP to keep your Cobra rolling along a flat plane at 75MPH, and only two or three times that if the plane is inclined (upwards, obviously  ). To really enjoy the .64 TKO, you have to live in an area where the highway cruising speed matches up with the product of your engine's quietest RPM, your differential ratio, and your tire size. The .64 is not for racing, nor even aggressive acceleration. It is for quiet cruising, but you have to do your homework and make sure it will work for you. If it does, then you'll love it, and if it doesn't, then you'll hate it. But, even if you make a mistake in the choice, it's not the end of the world. The transmission only weighs 100 lbs. and is not that hard to pull. You and a strong son can pull it, drop it off at the transmission shop for a gear swap, and then put it back in if you find you don't like what you have.  |
