@klaspeppar5619 A very good reply, hope you dont mind if I explain some things about what I meant, dont take it the wrong way...
Warning, long reply But I think you will find it worthwhile...
Yes, 250hp is very believable, no doubt about that. But how is the number 250 reached? Most tuning companys dont have the resources to test engines the way manufacturers does. They also have an incentive to inflate the numbers, and little to no negatives in doing so. Many people will buy the tune that promises the most hp increase.
But that also goes for the engine in the Golf of course, since it also is tuned by a tuning company.
That doesnt mean the numbers are untrue per se, but that the variations could also potentially be larger. And if your Volvo makes 260 hp, and the Golf 230, that makes a really big difference in the race, but is still well in the variation, I would say even a 15hp swing per car would be, so potentially 225 vs 265 or 255 vs 235.
As you say, there is also the condition of the car to factor in. A small leak or almost imperceptible misfire, some less than optimal old fuel, a slightly bad MAF and many other such things can sap 20 hp without being noticable, very true.
There is also the definition of what kind of race it would be. Lower weight and power gives an advantage at low speeds, while higher weight and more power gives an advantage in higher speeds, were aerodynamic drag is most important. So it could well be possible to see the lead change several times in the race, as the speed goes up.
The comment you made on the cylinders and torque is interesting, as I said dont take this the wrong way...
Number of cylinders dont matter. At all. They only matter in in indirect way, as in, can the car produce mpre horsepower because it has more cylinders? If the cars have the same horsepower, it doesnt matter they got 1 cylinder vs 12 cylinders, when it comes to speed and acceleration.
Same deal with torque, it matters only in an indirect way, as in can the car produce more horsepower becuase it got more Torque? Sometimes the answer is yes, sometimes the answer is no. But the "peak Torque number" in itself doesnt mean anything when it comes to maximum acceleration. Only "in gear mean horsepower" does, which is a number that is not availible from any manufacturer or tuner as far as I know.
Yes, the DSG gives a big advantage, even though it saps sligtly more power and makes the car heavier than a normal box. But at very high speed, where the shifting is a smaller percentage of the time spent acceleratiing, then the advantage goes back to the manual box, for the reasons stated above (less weight and power loss). VAG themselves used a manual box in their Nurburgring lap record attempt with a Golf or was it a Seat leon Cupra, dont remember, but they are more or less the same car anyway. One or the other.
Yes, indeed it would be very interesting race, too bad I dont have my old tuned BMW 120d diesel, which could have added an extra dimension. But with only about 215-220hp and more losses since it was rear wheel drive, it would surely lose against both this and your car. I also had a BMW 123d diesel with about 270 horsepower, and that would have also been interesting, maybe it would have been slitghly faster.
Currently I have a BMW 335d, but it is tune to waay to much horsepower curerntly for it to be a worthy race for any one of us, though I suppose I could flash the software back to the factory standard of about 285-290 hp, and that would maybe be a bit competitive, since the 335d I have got is very heavy for being a coupe.
Hit me up if you are interested, It could be a fun race. Since You own a Volvo and got the name you have, I take it you are based in Sweden just as me, or am I assuming too much?
