.....I have never seen any good person reving a kt100 at 14700rpm

How can you know how many revs people are doing without seeing their data? I've run within 3-4 tenths of my home track's clubby light lap record on a green track with old tyres while only revving to 14800. That lap record was set last year during qualifying at the QLD open states by Ben Stewart against the likes of Joseph Mawson and Cian Fothergill. Seriously, there is no hard and fast rule about how much these engines should rev.

Like I said, it depends heaps on how they are built. There are so many variables with the port cast and other adjustable items that the engine builder has at it's disposal (cylinder head shape, squish band size, port timing, different piston, piston skirt length, ring end gap, ignition timing, etc.) that you could get two engines doing the same times with different gearing, one revving to 14700 and the other revving to 16000.

No idea, optimum is probably somewhere between 150-200. Someone who races this class should have a better idea about it.

We can sorta model air cooling right now, the biggest problem is that the starting temperature is always optimum, so if optimum temp is 180 degrees that's where the engine starts out of the pits in KRP.

I was the first to vote 4/5.

If someone is willing to do the 3D work and we can get access to a dyno file I don't see why we can't make this happen.

Yeah like I said that was just approximate. All of the five S engines that I've used have only revved to 15300-15500, sometimes less, and yes they were good engines. It depends on the track and how they're built, but I do know some people rev them higher.

unless you have super strong neck muscles then you pretty much are an idiot for not wearing one if your in something like KZ, KZ2, KF1, KF2 or pretty much anything fast and has sticky tyres because your pulling over 3G's through some corners and doing that in a final which something like over 30 laps  without a neck brace is just suicide, how you would keep your head up when driving is one thing but how you would handle getting out of the kart after and doing all your other things would be just plain annoying and uncomfortable. The wet you don't necessarily need one because it's not so fast and grippy but it is defo recommended to wear one if you don't have strong neck muscles both in the wet and dry but more the dry, wet is easier to handle

Here are a couple of photos from KZ and KF last year, count the number of neck braces:




Do you think nearly every Australian CIK entrant is an idiot? The series was revived 4 years ago with KF1 and KZ2, and in that time there have been a few pretty massive crashes, yet no broken necks. Neck braces are more so a marketing thing than a genuine life saver, they make it out to be incredibly easy to break you neck and that if you do roll over you will break it unless you are wearing a neck brace, however in reality they can do just as much harm as they do good because they can jar your neck and generally transfer all those forces to another weak point on your body.

In my 4 years karting I've only seen one accident where a neck brace would have helped. The kid wasn't wearing one but he walked away from it....after he regained consciousness. I think they're a good thing for younger drivers whose necks are still relatively fragile, but for most adults I don't think they're really needed.

Most drivers around here don't wear neck protection. I find it extremely uncomfortable and the good ones are too expensive.

All you need to do is delete everything in the install directory except the skins and tracks you have installed, then install the new version over the top. That worked for me anyway. All the additional karts from beta 8 no longer work, you'll have to wait until they are updated for beta 9. I hope to have the X30 updated next week some time.

It's only compatible with beta 8, you'll have to either reinstall the older version or wait for the update. I plan on updating once I've tested all the default KRP karts then mess around with tyre selection and ballast again. Hopefully I can also get a proper dyno sheet, and maybe even actual engine 3D models however I don't know how far along LauZzZn is so that might have to wait for the next version. I hope to have the next version out within a week or two.

Yep - Inside, Middle, Outside

KZ1 is simply awesome to drive, I'm running a more realistic setup now due to the tyre changes and it feels great. Same times as B8, but more fun and realistic. The new cadet kart is massive fun too, I can see racing that kart being lots of fun with a big group. I'm yet to test F100 or KF3 yet, but I did more testing with the KF1 and I also noticed the problem of lack of temperature. It feels great once temps are up to 60-70 but that takes like 8-9 laps which is 5-6 laps too long. I'll do more testing tomorrow before saying more but so far I think it's a sure improvement! Only downside is the temperature build up.

Something changed for sure, the karts are much looser now. It's a bit more realistic but definitely harder now. Almost the same times in KF1 (42.1 at Lonato) but I had to change my setup a bit.
