Optimum shift in 1.2?

[AhmedRSi]

Out of interest... when really giving it some (which i wouldnt normally do...) whats the optimum revs to shift at?

Car is 1.2 8v

 

[C.slicker]

I think for the 16v (which I have is about 6k). After 5.5k the power curve falls with an ever increasing gradient, yet a change at 5.5 will mean the next gear is going to come in at about 4 which will be too low for optimum.

I would say 6k but not sure exactly for the 8v

Thanks, Well my max revs is 7000 on the dial and rev limiter kicks in at about 6500 iirc... anyone know what it is for an 8v then?

According to the Renault book.....

1.2 8v: Max Power: 60BHP @ 5250rpm
Max Torque:93NM @ 2500rpm

1.2 16v Max Power: 75BHP @ 5500rpm
Max Torque: 105NM @ 3500rpm

 

[AhmedRSi]

So i should shift at 5250?

 

[Wilkeh]

i wudnt even bother giving it some tbh

 

[Mells]

Your lucky to have a rev counter. I havent!

its a 1.2, just have fun in it dont go all tec like, next it will be if i take the jack ot of my car i would be 0.01 secs quicker, i have a 1.2 8v that hasnt even got a rev counter bt i dont care lol,

Drive like a taxi driver! 4th gear all the way!

lol my old 1.2 used to hate being reved even to 4k it was like CHANGE!!! was a reet shock when i got the 172 as insted it was going MORE MORE CUMMMONNNN GRRRRRRR

 

[AlexS]

Mine revs quite freely all the way to the limiter, does a ton in 4th when its nice and warm. I rarely ever take it over 5k though, and round town it rarely sees 3.5k.

When my 1.2 16v was rolling roaded, it hit peak power at exactly 5500rpm

 

[Pep]

just take it right to the limiter in as many gears as you can where ever safe and you'l be fine

 

[teeCup]

lol. peak preformance from a 1.2! i got the same but its 16v, jus thrash it to just before the limiter and have a laugh!if i dont thrash it, it barely moves!lol

i like your style!

 

[_M_A_T_T_]

my 1.2 8v was best bout 5500rpm but it doesnt urt it 2 take it all the way

 

[AhmedRSi]

thanks ill just rag it till something blows up then

 

[sh33n]

Just flat shift, Reno gearboxes love that

 

[AhmedRSi]

flat shift?

 

[jayxx83]

change b4 engine sounds like its gna drop out.

 

[C.slicker]

Yeah you could do as above.

But as you said it may blow up.

I recommend changing at 5750rpm.

If you want your engine to blow up though, douse it in petrol yourself then light it...gives a bigger bang that way.

 

[Chadwick]

If im really giving it some (trying to catch up/keep a decent distance from my mates) then the most i will give it is 5000rpm, then it sounds like its not far away from happily throwing a piston in my face. Day to day driving, 4500rpm is the optimum rpm ill give it.

 

[Whiteley]

Limiter on my old 1.2 8v was at 6250rpm, Change just before 6k and your about right. No beans behind the engine to start with though! :approve:

 

[Capture_db]

usually change about 5500 on my 1.4 16v

 

[edde]

You need to get it on a RR realy and shift points chnage with what gear your in as you want to maximimse power all the time also depends if your racing the 1/4 mile etc as sometimes it better going well out the power band rarther than change up.
Changing up at maximum power isn't often the best idea.

 

[NOT! gary l]

Looking at the rev counter every time you change gear is a bit sad, just a thought but why not change gear when the engine sound is telling you to? and in a 1.2 8v that is WAY before 5k revs.

So youre trying to catch up with a mate in front in of you, eyes firmly stuck on the rev counter at 5.5k revs doing about 45-50mph and you havent yet realised that youre mate in front has hit the anchors as the car in front of him has performed an emergency stop.

Just a wee scenario but entirely possible by the looks of some previous posts.

Its a 1.2 8v doesnt matter how much revs you give it it's never gonna be quick, it wont rev past 6k so taking it to 5500 every gear change is doing it no good whatsoever.
