power

[Jack powers]

i'm still new to the whole forum scene so apologies if its in the wrong section, still getting to terms with how all of this works.
anyway, it feels to me like my clio 182 starts to hold back a bit somewhere between 6.25-6.5k revs, all the way to the red line.

is this normal?

the car is standard other that a scorpion cat back system

Should not hold back no. But i guss they do lose some power around that sort of rpm. Belts done recently? If so where.

Usual stuff really. Sparks, coil pack or leads. Dodgy injector

 

[Jack powers]

i think hold back would was probably the wrong term, id say slight loss of power. not really noticeable in 1st or 2nd gear

 

[N4TH4N]

As above then really

 

[letsturboit]

Dont they stop making more power around that rpm? Most peoples rolling roads graphs on standard cars show a little dip around that rpm.

More power? Shift up?

 

[jamesycc]

My power peaks 6800 rpm but will go to 7400. Difficult to be helpful. Could book it in for a rolling road session to see if that shows up anything or drive another 182 to compare.

They should pull to the limiter but peak power is around the early to mid 6K's as stated. Depends how sensitive you are to the torque drop off or you need to start checking for a cause. Starting with service items.

These cars have a two stage rev limiter, the lower revs stage works until engine has reached full operating temperature. No need to go to max revs anyway, unless in a race where the changing up of a gear just before a corner will necessitate an almost immediate downchange thereafter.

 

[warwickstingray]

Cold rev limit is 6800rpm but can come in as low as 6500rpm. I had the impression the OP was feeling a drop off not Hittimg a wall.

 

[Jack powers]

What should the rev limiter be when it is hot?
I'm sure mine is about 6800-6900 when hot

 

[Mr Plums]

7250 iirc.

 

[GrahamS]

Sounds like you need a decat my friend

 

[warwickstingray]

7250 in first 3 gears.

 

[Mr Plums]

What about 4th and 5th?

 

[warwickstingray]

7000rpm I've nudged the limiter in 4th at track days so I know it's lower. One of those straights where 5th is no use so you use all of 4th is the culprit.

 

[Mr Plums]

I doubt you could hit the limiter in 5th in a standard car lol.

 

[bozothenutter]

timing?

 

[coverman]

172 Cup declared max speed equates to 6682 revs in fifth

 

[Jack powers]

I managed to get it to 7250rpm yesterday (first time I can recall it going over 7k) . Which leads me to believe that it's a faulty thermostat

 

[Mr Plums]

Just make sure its fully warm before thrashing it, usually takes around 20 mins or so then it should rev right round.

 

[Goodj]

As above.
If you try hammering it from cold it will try and stop such things in the name of self-preservation.
Faulty thermostat? Probably not else its unlikely you'd have got it free up at all.

 

[Jack powers]

I never wind the thing up until about 20 mins of driving anyway. I'll try leaving it longer before thrashing it and see where that gets me

 

[Mr Plums]

If it doesn't go round the 1st time, try it again and it probably will

 

[Dooby]

I had this issue where it would cut the limiter in early on a warm engine. was a faulty CTS.

 

[warwickstingray]

Phase 2 fifth gears are quite low. I bet there's a few downhill runs in the UK where you could hit the limiter in 5th in you were insane enough to try.

As mentioned the ECU has a present temperature to reach before increasing the rev limit. If these conditions don't occur through faults then no raised rev limit.

Honda's vtec won't engage until the engine is warm. They are wise to not trust the average driver.
