Theoretical Top Speed....

Hey, I know that people come on here to get a break from school and stuff but maybe someone could put all of those physics formulas and stuff to work for me.
I couldnt even figure out where to begin.

Heres my question (and stuff that is relevant):

Assuming that my GA16i engine could pull all the way to the redline (which it can't right now) in third gear, what is the top speed that the car could reach?

My car max's out at 165km/h pulling about 4000RPM.

I have a GA16i that redlines at 6200. I also have a 3 Speed Automatic. Gear 3 I believe has a ratio of 1.000 and it has a final drive ratio of 3.476 .

Also to make it simpler, i would ignore any wind resistance, drag or friction.

-Nick

When I had the GA16i and 5 speed, I was able to slowly creep to the indicated 105 mph on the speedo with 13" stockers. After going to 16's I was only able to muster a wopping 98 mph. I then shortly took the motor and threw it away.

in my 4door b12 with a stock e16s i managed to go over the 105 indicated on the speedo. i dontknow how fast i was going but id guess 115 or so and that thing was screamin. i think i might have also had wind from behind.

Let's just assume your rate of speed is proportional to RPM (remember KISS) then you should see on your speedo 255.75km/h at 6200 rpm

Damn you all have me beat. My e16s tops out at 85-90. My 3 speed automatic transmission is worn out badly though.

This is a sad thread all of us bragging about going just a tad over 100mph we should all now hang our heads in shame.

Ha! It really is all relative, isn't it?

Yup, I never took the Sentra 10/10ths, the fastest was a buck-five, but she still had a little more in her. I've got Ziex's, custom exhuast, Weber on it.

In my 240SX, I got it up to 115 really quick, and then let off before the fuel cut had a chance to cut in.
