Losing power on airfield this morning

[Maccy]

Have never noticed this before when on the motorway, but was on an airfield this morning with my uncle and some of his friends, took the micra on and tried to get a top speed out of it.

Now, I have managed 100 out of it before :blush: and I got to about 97 and then started losing power. Engine started to crawl down to 90 and wouldn't budge from it despite me flooring it.

Any idea on the causes? I wondered possibly tyres....

my facelift went faster in 4th (IIRC 115mph) than 5th (95mph)

Yeah 5th is more for cruising

wind direction would also have an impact.

I presume you were in the lowest gear possible at the time? Anyway I bet it could be down to wind or similar and not necessarily something to worry about, airfields can be a lot windier than a motorway!

Discussion of speeding on public roads is not tolerated on the MSC

i have probs aswell i get up to 7k in 2nd well thats 60 the other day in 3rd i could get to 90 at 7k but now only stops at 6k but only in that gear is it a related prob or did i just destroy 3rd gear

 

[Retepetsir]

No point revving to 7k, you're out of the powerband at that point.

when i took my old Green K11 onto a private air strip it had a flat spot of about 85-90 and started to loose power.I just put it down to a flat spot but i guess Olly is right and that 5th is for cruising

 

[bolton_18]

where can i find out the powerbands for different micras

 

[whipit]

I Found i got best performance changing before 5k in a coil pack cg10 and carbed 1.2 k10! Quite sure nissan design the engines for low end torque.

 

[bolton_18]

klkl ye not much happens after that any

 

[nO_JeZeBeL]

oh man, so much easier in an automatic ...

just need to get it tuned for a faster response...

 

[bolton_18]

nah each to there own but i find manualls more fun

I get a higher speed quicker if I shift at a lower RPM than if I redline on the changes.

It would be nice to know the ideal shifting point though so I could set up my shift light.
