Hitting the rev range early? Help?

[rsNick]

Sometimes when driving I can rev right through to 7,000+ but other times it only let's me rev to about 6/6500 and it's not just when the engine is cold. Other than this it runs perfectly, just hits the limiter early?

Can anyone explain why this happens?

Thanks in advanced

Are you sure it's up to temp? thermostat, coolant sensor, new kettle

 

[The Dominator]

Bet it's not at it's working temp when its restricting you

 

[Gandi69]

even though the water temp gauge is at half way, sometimes its still not warm enough to allow the upper limits of the rev range

 

[rsNick]

Alright thanks guys

it probs is just the temp then, how long would u say it takes to heat up roughly? Suppose it depends.
I must just be impatient

 

[hipwell]

I usually give mine untill the themp gauge gets to half way and then another 5 minutes or so just to make sure the oil is upto temp aswel.

If yours is still hitting the early limiter after that then id reccomend getting a new thermostat and maybe a new coolant temp sensor.

 

[The Dominator]

I would say 10-15 miles...could be wrong

 

[Dan519]

almost definitely needs a new thermostat (like most of them do) if it's not getting up to temperature and/or staying there

 

[Dan519]

lol, that's a pretty long journey to not be up to temp. 2-3 miles should be adequate

 

[Chip-mk1]

"Middle of the gauge" means nothing sadly, its a massive range of temperatures that it sits in the middle for, from well below the cutover point, so it looks like its upto temp enough when it isnt.

 

[imprezaworks]

Depending on the conditions mine normally takes five or ten mins

Really, About 6 months ago I called you as I was having issues with my car turned out to be a thermostat, You said take it for a good run and get it up to temp and advised 10 miles lol?

 

[Dan519]

probably said 10 minutes??

mind you, if it was the stat not working then it would have taken longer to get hot, so I was probably telling you to get it really hot and see if it fixed it = stat needed changing

 

[The Dominator]

If you say so lol

 

[Dan519]

see edit

 

[The Dominator]

?

Just seen that my bad appears Danny was right- Again:rasp:

 

[Dan519]

if it had a problem and it was down to not getting hot, I would have told you to go for a long drive to get it hot. With a working stat it wouldn't take long at all

In the grand scheme of things, it really doesn't matter.

 

[The Dominator]

Was actually asking Danny as I was curious as to why he had advised 2 things but im sure if you read the above it is explained so it has answered the op's question and my own

So yes it did matter

 

[Silent_Scone]

If you say so.

 

[The Dominator]

If you say so.

Clearly yes as stated

Mine runs the cold map for about 10mins at 60mph (so 10 miles). It obviously quicker if its hot outside, but most of the time in the UK its not

Yours isnt working properly then.

 

[The Fatty]

Really? Id say it works fine. Maybe its more like 10mins, 40% of which at 30mph and 60% of which at 60mph; I have to be half way to barnstaple starting from the centre of south molton before the hot map kicks in. All I know is that when the temp gets to half way, it still needs another few mins before the warm map kicks in. Once its warm it stays in the warm map just fine.

Change the stat, its 20 quid and it will save you fuel

 

[The Fatty]

ok I like things that save me fuel!

 

[Jay_G]

Isn't his limiting early still tho? (I'm just a bit excited as mine sometimes limits/splutters at 5,5k-6k and never seen someone with a similar issue), but ALLWAYS stops doing it when the temp gauge is bang on middle.

quick question, sometimes it will never get to the middle on a 30odd miles journey, just sit below it, just over half way between quarter and half. New thermostat?

 

[The Fatty]

it shouldnt limit at 5.5, it limits at 6.5. when its hot it goes up to 7.2/7.5

 

[Jay_G]

It's not "exactly" a limiter, it just completely loses power, and bounces around at them revs, normally bounces between 5-6k, not a specific rev. It's like a limiter, with the way it completely cuts the power, and won't rev higherhigher

 

[Jonnyf007]

CTS sensor and thermostat need changing....

 

[Cookson]

Oil temp is not.depndant on time. Its how the engine is used. Obv if people tickle its arse for 15mins, its not gonna be as warm as someone that works the engine up the rev range properly

 

[The Fatty]

I tickle lol
