Why can't they make a manual with tall gearing anymore, *cry*

But it's okay, because I can rub my hf tranny in everyone's face, :p

I think some of the high rpm gearing may be the result of strict emissions testing...I don't know, I'm guessing. Possibly less carbon, hydrocarbons produced from the engine working harder? I've noticed that my wife's Stratus runs around 2,600 rpm at 65 mph and my old Spirit (auto) was only 2,100 in OD at the same speed.

I think it's just because people want to floor it in 5th and go, :(.

From what I recall emissions are greater at higher rpms, but I forget for sure.

Well that's true (about
 

Well that's true (about flooring it in 5th)...

Emissions systems are so complex now though it's hard to say. Maybe the engine is producing more emissions, but maybe the system is burning off more or pouring more back into the combustion cycle?

My 85 CRX HF was at 1700 at 55, and 2500 at 80. Those were the good old days. :(

When I swap in the hf tranny to my 91 std civic hatch (with SVOboy's help of course), i will have reached a decent baseline of I'm hoping 45mpg highway. With the 4spd std I get 40mpg highway. I will be running over 1000rpm less than what I am at now on the highway! I got coroplast, and want to do some aero, and add vx rims = good for 50mpg? I am with DaX on 50mpg...a good round number.

If you're at 40 and dropping
 

If you're at 40 and dropping 1k rpms, that's a lot more than a 5 mpg improvement for just highway driving, sheeshers.

Scratch that. I get 40mpg
 

Scratch that. I get 40mpg tanks not just highway. I want 50mpg tanks like DaX!

sheeshers,

What kind of improvement, highway or overall, would you expect?

sheeshers.

10mpg, pretty please?
