nice story.
In the interest of dispelling /QOTW LIES I should point out that a Charade GTti is a single turbo not a twin and can't do 115, let alone average it.

mind, tidy cars, and you can overboost the turbo and make them even more insane. Pity 3 cylinder cars sound like a bag of nails inside a spin drier really.

I always thought the 'tt' in 'gtti'
stood for 'twin turbo'. But you maybe correct. Also, a minor tweak on the turbo easily allowed my car to top 130mph. The manufacturers stated standard top speed is 116mph, so they can make it that high. I know. I've owned two of them.

I doubt it stands for anything.
But no, one turbo. Cars of that era that had twin turbos used one per bank of cylinders, so two in the 300ZX for instance as it was a V6. It's only very recently that people like BMW have started twin turboing one bank of cylinders with a small turbo to spool up at low revs and remove the midrange turbo lag.

oh, and a mild tweak (or even a fuckoff tweak) to the turbo will do cock all for your top speed. That's governed by gearing and engine revs. It'll just make you accelerate faster.

It did easily top 120mph.
Here's some berk doing 220kmh in his gtti...that equates roughly to 136mph.

The green light you see flashing is the turbo indicator.

While we're in the process of correcting stuff
The Skyline's been a twin turbo straight six for, well, ever. That's just one example.

Of course an increase in power will increase your top speed, top speed in a car is defined mostly by the power of the car to overcome drag. I have never driven a car (and I've driven lots) that has topped out at the rev limiter.

And
The Mazda RX7 had sequential twin turbos plumbed onto its two rotor engine.

True, I'm just deliberately being an arse here.
Although, it doesn't make much difference to top speed, much more to acceleration. Small car gearing does take you close to the redline in top IME.

Anyway, given the rate of increase of air resistance with speed you need an epic power up to seriously alter anything at the top end.

The skyline is a twin turbo, yeah, but one per 3 cylinders, similar to the 300ZX system but on a striaght 6. I wasn't really being clear but I was differentiating between twin and sequential turbos really. Poster below is right about the last generation RX-7, it was the first sequential turbo production car I think, I'd forgotten that. But that engine was witchcraft.

cars topping out at rev limiter
the skoda pickup normally aspirated 1.9l diesel will merrily accelerate to ca. 150 km/h at which point the rev limiter kicks in.
this is due to a shorter diff gearing compared to the hatchback base meant to increase power off the line at the cost of top end.

This is top pedantry - good work!
Enjoyed the original post too *click*
