General Twin air pull back in 1st gear

[ovalbeanie]

I’m afraid I was responsible for this thread. My wife posed the question after I mentioned it to her. Thanks to all who have replied. (With the possible exception of Maxi360, who clearly does hate people having fun. I won’t, however, criticize him for that. He’s obviously suffered enough.)


I’ve driven the car several times and I do (mostly) try to adhere to my wife’s wishes on how I should drive her car. But, well, it is a fun car and, to be honest, I’d rather just drive it and not be monitoring fuel consumption every time I drive it. However, to the problem.


I should say that I have driven for 40 years and I know when a gear comes to its maximum revs and I seldom, if ever, go there. Though I sometimes go close, often to get away at very busy roundabouts, which is what happened on this occasion. A car in any gear will reach its maximum but then stay at that speed until the gear is changed. Our 500 definitely pulled back as though the brake had been applied, in many ways like the comment from Venters, with his analogy to parachutes. I just wondered if anyone else had had that experience.

Bovalweanie has hit the nail on the head. The moment I see or hear of someone having fun I start to cry.

Ovalbeanie, they're pretty robust little cars. I haven't had any major issues to speak of on mine and I'm quite agressive with her. Hit the limiter many times chasing people on track days. It's all good. Remember, they're designed to be driven like the Italians drive them.

But in the 1.4 there's still a bit of torque up there

Did your re-map alter the rev limiter ?

 

[TwinAir Newbie]

I have hit the limiter more than once in first gear.

It is easy to do as it is quite short geared.

The rev counter is a bummer to easily read so it is understandable what happened.

I don't like to mistreat cars either.

And you're right, the TA should be about having fun which is part of the reason we all seem to be getting mid 40s mpg!

Want to hear something unbelievable? I've never hit the limiter in the Abarth!

Is the limit in the Abarth higher up than the standard 1.4? Ive never hit mine. Might try tomorrow for a laugh. Might be difficult on my way to work but there is one 60MPH road for about 150 meters.

If i don't report back, ive crashed into the back of a slow car.

Make sure there's no one around and preferable in the 'dead of night' so there'll be no slow cars or sleeping police'men' on the road.

You're not driving it properly then.

 

[DraigFlag87]

Trust me, i am! It's just in a turbo car, i find it pointless revving much beyond 4500 to 5000 revs as you can feel the power fading. Better performance is achieved at mid range revs.

 

[Vance]

Only car's I'd take near the rev limiter would be NA cars that NEED to be revved to get the best from them.

As Draig said, pointless doing it in a turbo car as it stops pulling that high up the range.

 

[306maxi]

agree with Vance and draigflag

On saying that, i just realised the car in question is a Twinair. I kind of make an exception for this engine, it hits the limiter in less time than it takes to blink, and it doesn't have enough power for you to feel where the power band is! Fun engine though

It does have that rather diesel like low torque peak, and I have a feeling the 100hp one will have the boost modulated less at the top end, to give it more of a punch higher up.

I wonder why is the first gear ratio on the TA so low ?

 

[bgunn]

Especially as 3rd, fourth and fifth are quite a bit higher. Whats the FD ratio though? I don't think we're getting the full story from the gear ratios.

I struggled to get that little bit of information after a lot of searching. Would the FD ratio not be the same for all the models ?

 

[bgunn]

As the gearboxes differ, I think it's highly unlikely that the FD ratios are exactly the same, which explains a fair amount. Would be interesting to get the proper FIAT manuals for the car which will have the tech info in it. Wonder if you can buy them from FIAT?

I remember reading that there was always a delay with the Hayes manual coming out (4 years ?) but Dannyboy ? seems to be able to get 'his hands' on the type of information - he's ex-Fiat now.
