Car appreciation... the aesthetics, the engineering, etc

Want.

In that colour too. Lush

never had a 'grale in your yoof b&d? i am surprised

(popped my 8v through a dry stone wall in t'lakes...#csb #wac)

I lusted after 'Grale's, but German reliability outweighed Italian flair when one was trying to outrun the old bill from a dogging site.

Problem with anything turbo charged is the temptation to get more power. Then some more. Then a bigger turbo. Then intercooler etc etc.

The problem with turbo's is lag.

It's why Bond had a supercharged Bentley.

I don't mean to sound harsh, but selling it could free up a fair bit of cash, I'm assuming it's a 993 or 964 if you bought it ages ago? They command a premium now and hold their value, you could keep it in the family and downgrade to a Targa or C4, and probably make £20-25k.

I ran the Falken FK452s on my old E34 and they were a pretty good tyre. That mid-range between premium and budget tyres.

What width are your rears? 10J? 295/30/18 is an expensive size.

I have thought of selling it. But I want to hang onto it as long as possible. Its such an amazing car. If my finances recover, then all will be well. If not, it will have to go. I am optimistic, which is perhaps why I am hanging on.

I wish it was a 993....but then it would be even more horrible to sell it. Its a 996, 2004. So worth far less.

Its been tweaked a little, by a local Porsche racing firm, to 505bhp. But thats not really had an impact on tyre wear. They never do many miles, apparently, on Pilot Sports.

Hard to give up a car like that.

The 453 is supposed to be an improvement on the 452. So I will give them a try.

But a charger takes some power to create power. I remember hearing of a charger that took 50hp just to run it. Engine did produce something silly like 600hp though

They're good for off-the-line grunt, but as you say its a parasitic system running off the crank.

The Jag XJ supercharger was said to take 100 horsepower to make 400.

A turbo charger has to spool- a boost threshold below which the car is sluggish, but above that the turbine will keep adding power as the revs rise, running on the exhaust gasses to make that power.

Supercharger for drag racing where you need boost off the line, turbo charger for circuit- where you can keep within the rev range that is supported by the turbine.

That sounds interesting, get some pics up!

an ovlov crossed upon some ice (for neil). i'd love to do this winter rally one day

Seems like a fair exchange to me.

Wasn't VW's G-Lader charger supposed to be super-efficient. (if not very reliable)?

Technically very clever, hardly ever functional I believe.

I think the issue is more that with the Jag you had a supercharger taking 100 to make 400, whereas at the revs that the Jag V8 was making that 400, with a turbo it would be 600+.

NA all the way!

What's a modern F1 car engine put out, Mick, per litre?

And how does that compare to the 1.5 litre Honda V6 from the turbo era, or the BMW 4 cylinder from the same period?

(i.e. comparing cutting edge to 20 year old tech)

A hell of a lot less!

These days it's relatively easy to get 300bhp out of a sub 100kg engine. If you need more than that, your car is too heavy.

(Or you're racing, where forced induction belongs)

Though it should be noted that those 1000bhp/litre qualifying engines lasted for a qualifying session (well, a hot lap). Modern engines need to last 2.5 full race weekends.

I've always wanted to try a Twin Charged engine. Have you any experience?

Fast.
A lot to go wrong.
Mental.

swings and roundabouts: a supercharger is parasitic but a turbo can be heavier due to all the plumbing to get the exhaust gasses to it...

twin turbo - twin charge?

twin charge = suck & blow, no?

Yarp- positive displacement blower and turbo, with intercoolers between the stages (or the turbine impeller can melt).
