Not sure why you're arguing with people who are pointing out flaws in your work, but you should listen to your critics if you want this car to ever be as good as it could be.
Physics wise it's ok, that's about the nicest thing I could say. It drives like the old Formula GT in Gran Turismo 5. Feels strange and unrealistic. I've found a lot of F1 mods with unrealistic physics though, so you're not alone there.
As for your insistence that it has 900hp: I checked, and it has 1034hp. These engines had close to 900hp at the crank, so this figure is off by some margin.
The sound is also not good, but this is another area where a lot of F1 mods are lacking, so it's not really a big deal.
Lastly the model: This is good, the only disparity with the real R24 is the sidepods on your model are a bit mis-shaped, with the upper shoulder being a bit too flat, and the bulge mid way down the side not being there on the real thing. But other than that relatively small detail, I'd say the model is pretty good. Good job on that if you did it yourself, and the people saying it's not sized correctly are wrong, it has all the correct dimensions when I checked.
Overall I'm giving you 3 stars for the good work on the model, and for the fact that with some work on physics, and if you listen to the critics, this could be an excellent F1 mod worthy of 5 stars. I'll gladly give you 5 stars if you address the issues.
Keep the good work up, and take this critique for what it is: a critique. I'm not being a "hater", or needlessly bashing your mod, I'm offering criticism of what isn't right, and praising the work you've done well.
