Ok, ever since I modded my car with a full exhaust (y-pipe, b-pipe, high flo cat) and intake (WAI pop charge), it seems as if my top speeds have changed a bit.

All I noticed was my third gear tops out at 98 MPH. I also just glanced over to see that my 2nd gear tops a little over 60 MPH. The owner's manual says 2nd is around 55 MPH and 3rd is about 88 MPH.

Is my tach or speedo off? I'd like to know. If you have the same mods (or close to) what do you top at?Thanks for the insight.

It's the owners manual, tehy have safety, non performance in mind, and if you mean you have different speeds relative to different RPM's, you're wrong.

Even with differnt tire sizes, your speed/rpm relation will never change, even if your true speed is off due to your tires because the speed/engine rpm are calibrated and will enver change unless you get different gear ratios and swapped them in, or final drive of course too.

OK so what you're saying is it's normal to hit 98 in 3rd? If that's the case, my question is solved.

I can see 98 in 3rd. If you had a mevi wouldnt that change the speed in a specific gear???

A MEVI wont change it, just make you get there faster, only mods that will change that are swapped gear ratios or an increased rev limiter, NOTHING else.

that sounds about right i hit about 62 in 2nd and about 97 in 3rd. 01 5-speed AE. im not sure if the limited slip has a slightly different ratio or not. i shouldnt, but it might.

if you put more power down with mods/bolt ons, why wouldn't you shift at a higher speed than you did stock?

how do you think cars trap higher speeds at the track? Your rpm ratio will never change unless you change out gears. Your speed in each gear will varying depending on the amount of power you put down.

what he said.

You wouldn't shift at a higher speed because you would be over-reving the engine. Your speed in each gear will not vary depending how much power you are putting down, because as you mentioned it is a fixed relationship between engine speed and road speed. With more power however, the ability of the car to get to redline faster increases, which is why the car is quicker.

66MPH 2nd- 100 in 3rd, 125MPH in 4th, 159MPH in 5th.

HP doesn't change your gearing. You will hit the same top speed in eahc gear no matter how much hp you have. You'll just get there faster.

I didn't realise that the overrall gearing is shorter than a 3rd gen 5speeds, awesome.

okay there we go, overall time to get to those speeds are faster. thanks for correcting me
