Gimme a few mins to get to a real keyboard and I'll update this post with helpful stuff.

Ok. Sorry, was on my phone and with a freshly-sliced right index finger, anything more than a few words was painful to type. Literally.
Anyway... on the sounds, we actually got an update for them last night from iRacer with the global volume lowered, so I wouldn't worry too much about that. We all agree it was too loud - it's been addressed.
On the power thing, if you want to test the pace of the car now to see if it's worth it, the procedure is very simple: I've included all 3 power curves in the data folder, labelled
power[xxx].lut where 'xxx' is the peak bhp rating. To do an 'engine swap' on this thing, simply delete power.lut from the folder and copy power[445].lut in its place. (Don't just rename it, make a copy and
then rename it. This way you still have all 3 options backed up and you can swap at will.)
On the physics in general, yes, IMO it felt fantastic after 1.11.0 but this car generates aero lift, which was bugged until 1.11.3, and now that's fixed the thing's a bit of a deathtrap. I've been working on it for the last couple of nights and I think we're getting close.
Can't say for sure (Mantas is the boss) but I'd expect an update sooner rather than later.
