1.3 A-Series Maximum Engine Speed

[Stu_CDX]

Right, as you all know, I've just got my 1.3LX 'Stro.

I was wondering, screw the facts, what is the maximum engine speed that the car can take?

I was wondering when sitting still on an icy slope in 3rd gear with the speedo pointing at about 65 waiting for some traction as I don't have a rev counter (Yes yes, I CAN hear the noise of an A-Series!) but the book says 5500 is the maximum and you can momentarily to 6000 without killing anything.

Well, on ice, with varying levels of adhesion, it's hard to get it just right and I'm worried I may have done some damage.

Now, this ISN'T an invite for a hate campaign, but I saw the speedo fly up to 40 in 1st gear, but there wasn't anywhere near the noise I'd expect.

My old 1.3 would rev to 6500rpm and my Mini would go to 7k but it did have a better cam. You'll know when it wont like revving so high when the valves start to bounce, there isnt any need to go over 6k because useful power drops before then.

Have you ever thought of just walking ? What kind of answer do you expect to a question like this apart from the logical assumption that you are indeed completely mad.

Walking to the pub would indeed be quicker, as even with my brand new front tyres, being as the pub is up hill, I still can't manage to pull off!

My driving instructor always said use the highest gear possible, which IMHO is 3rd on my car as it's a 5 speed.

I'm not mad, but I did want to get to my destination and I was asking a genuine question.

I thought your first post was daft enough. What on Earth are you doing revving away in 3rd gear on ice at such engine speeds that it's showing 65mph? What if it burnt the ice away and suddenly got traction?

Now you're saying you're trying to drive to the pub? Digging a bit of a hole, Stu...

Reading this quoted post again - You're trying to take off up a hill in 3rd gear? Why? I've managed perfectly fine by gently taking off in 1st.

I think you should stick to walking, Stu.

I was thinking more if one wheel got traction and the other did not. So one side was turning at 130mph whilst the other side was stationary. How long could the differential stand up to that :banghead:

Try not revving the nads off it on ice, which isn't going to get you anywhere. How about rolling down the hill to a point where you can get traction, or keeping some old rolls of carpet in the boot for such emergencies?

I get the impression from your first post you were just hopeing to 'wear away' the ice with the tyres spinning?

[E_T_V]

Driving on ice or any slippery surface for that matter requires low revs, not high revs when going uphill, (the opposite going downhill). I remember proving this point nicely at MGSD a couple of years ago. The missus was driving my 600 which was towing a trailer with all the club stands gear in it and she sat spinning the wheels trying to pull off up a wet and muddy hill. I yelled at her to take her foot off of the throttle completely which she looked a bit strangely back at me then promptly did and the car pulled away nicely.

As for how high an A series can rev, well that would depend on if it is modded or not, but a standard one will start protesting above 6k and there is no useful power up there to be had anyway. If overrevved you get valve bounce and the piston ringlands tend to shatter too so not a good idea.

Bet you paid for that later.....:laugh:

Steve... You'd have struggled to get up it. First gear was doing nothing. My idea was to burn the ice away.

No idea about differentials, I don't understand cars much, I just drive them.

Rolls of carpet? Now... That sounds like an idea! No chance of rolling down the hill as I was at the bottom. :(

Thanks. Sounds like a good answer. I know there's no power up there, but I didn't want to damage it and if there was going to be, I didn't want it to get progressively worse.

My thoughts exactly. :laugh:

I don't believe there's a crime in driving to work is there?

I beg to differ. The idea is to set of very gently, as Dan says, using low revs, using the engine's power but with only gentle movement so as not to slip. You revving away in 3rd with the wheels slipping, as mentioned would be highly dangerous if one or both wheels suddenly gained grip. It would lurch forward out of your control and most likely stall as it isn't going to set off in 3rd, especially up a hil. So all that effort would have been wasted, possibly in a dangerous way.

No idea about differentials, I don't understand cars much, I just drive them.


We can tell.

Good idea, indeed - but you'd have to stop again to pick the things up. ;)

You should have said work then, shouldn't you, Krusty.

Will you two put the handbags away?:sissy:

This thread is priceless :rolleyes: , What did you try after this ? Super glue on the tyres :laugh:

[BikerGran]

Play nicely children!

[MaestroTurbo]

Burn the ice away? :S

Call me stupid, boring or just plain lazy, but I'd just spray some De-Icer on it... ;)

I'll call you all three...

De-icer? Lol... Last time I used that I was about 6 and wrote Dad on the windscreen of my Dad's car with it lol (When it was icy).

Now you can write it in the ice on the road with your wheel-spinning. ;)

Anyway, what actually happened, did you manage to set off up the hill in the end?

Seeing the Bank of England has just cut their official interest rate again reminded me of this thread. If the UK were a car, the Bank of England would be the engine and clearing banks the gear-box and wheels.

The clutch is broken and we are stuck in neutral, meanwhile the BoE just keeps revving that engine for all it's worth. Soon the tank's gonna be empty.

Until there is a connection restored between the BoE rate and the real economy, what is the point :banghead:

I took off at a nice steady pace up the hill, then stopped on a dry patch and got going quite nicely.

What the bloody hell is that all about!?

Sorry, I shouldn't have posted that, because I don't think we should spoil this excellent forum with stuff like the economy or politics. It seems members can find enough to fall out about without that :sissy:
I will try to engage brain before mouth in future :o

Don't forget to fix the clutch first. ;)

I don't think Stu quite got the analogy, surprisingly... :p
