i personally think that netkar engine sounds are kinda lacking, compared to the sounds of formula cars in rfactor. the sounds of cars in rfactor (not all though) had the "rush" of a real engine. you can even feel the "vibration" of the engine through the sounds alone. but with the netkar pro the engine sounds feels kinda canny, it's like something's lacking. it doesn't have enough transmission sounds too, i would like it to be more noisy, it's a race car after all. and also the engine sounds should be more noisy to the engines just sounded too clean. (i hope I had thought of a better word than 'noisy' haha) if you have tried the AE86 mod in rFactor, it had, by far the best engine sounds in all the rfactor mods i have tried. it sounded really good, plus the transmission noise adds to the whole adrenalin. i hoped netkar was like this too. IMO it's only the thing lacking from netkar pro for it be perfect for me. the skid sounds are great though do you know any sound mods for netkar pro? i saw someone in youtube with sound mods, but the dl link was already dead. also i stumbled upon this netkar pro sound crossfade, but also, having been posted in 2007, the DL link were already dead. it would be great if Kunos released a new soundpack for all the cars. just my 2cents.
