Rev Limiter 4th Gear

[Toypop]

At what speed was I going when I hit the limiter in 4th?

 

[Liam]

mmm, not had chance to try it myself, but i would imagine fairly rapid...

guess at 120ish?

 

[fUbAr]

speed of sound?

 

[Toypop]

Given that we know the gear ratios is there an accurate way of measuring it?

 

[chris182]

Is it not just easier to look at the speedo

Why didnt you look at the speedo?

Also was the engine hot or cold?
Had you been driving for a long time?
Were you going down hill or uphill?

Like come on man... if youd looked - youd know. IMHO your looking at between 110 and 120.

Not allowed to discuss that on Cliosport anymore. Needless to say I was concentrating on something else, in fact the limiter caught me by surprise.

Also was the engine hot or cold?

It had barely/only just reached full water temperature, I know I shouldnt have pushed it so soon.

Had you been driving for a long time?

5 minutes, again I know I should have let it warm up.


Were you going down hill or uphill?

On the flat

Limiter caught you by surprise? The shift light is on for quite a while when your at the top of fourth gear.......... Sounds like it was cold, so limiter would have been at about 6250 rpm.... about 108 mph. Not completely sure becuase I think the gear ratios are slighlty different in the 182 to my 172..... my 172 does about 114* in fourth. On a private runway.

*this is not GPS verified and is only my guestimate from galncing at the speedo.

 

[Toypop]

Yeah I think it would have pretty much got to 7k or 6900 at least as I am sure it did in 2nd and 3rd. But normally I can go just over 7 before it comes on?

My Cup can hit about 125 in 4th at 7800 rpm, standard must be about 110/115..

 

[ken182]

7800rpm?.. they dont rev that hard. limiter cuts in at 7200

 

[Neil82]

Mines chipped.

 

[ken182]

ah.. touche

 

[Toypop]

I change up at 7k anyway as you can feel the power dropping off at that point. I assume that chip does more than just raise the limit because I feel I would be better off changing up than going past 7k.

Dont know how it is on the 172/182s but on my williams my car is noticeably faster revving to my 7.1k limit than a standard car changing up at 6.5k....mine does 113ish in 4th btw.

LOL I need to raise the 6500rpm limiter badly, managed to hit it in 5th today!!

 

[cup_racer]

Strangely enough, i almost hit my limiter in 4th today aswell.



Changed when the change light came on.

Never managed to hit the limiter in 5th in my 172...just dont have the power to get past 5600rpm...

My car makes 172 hp@ 6k 181@6500 and 179 hp @ limiter @7800 rpm. Torque dies down a little but it pulls very cleanly to the limiter with no slow down.

i can do 120 in 4th, i use it from a standing start to the top of the slip road onto the A34 by the time i reatch the middle of the filter in im doing 110 - 120
