I'm using the aluminium shim only for 15% in my D5.
I've had to lean my mid-range needle and im also now playing with the pressure fitting on the pipe (not yet tested but ive moved the hole to forward of pipe) Seemed ok at my house but I need long straight to test.
BTW you using stock NTC3 pipe or RLogic D/THS pipe?

Stock FT NTC3 pipe. I have read other places where the pipe has been deemed to be an issue, but if it was ok with other engines (they varied a little from full tank to empty tank, but never ran this hot!), then I don't want to be chasing my tail. I'm going to install the Novarossi engine tonight and see how that goes.
After that I'll see if I can still be bothered with the STS.

Also I tell you one thing,most of the thermometers on the market are not precise. Except you use high price temp gun(more than $200US?!). I have tested many thermometers,all of them have huge different results. Sometime even more than 20C different. I don't know which one is correct so I use "Exagen" now.

I actually wondered about this. I use a venom on board monitor which isn't going to be highly accurate but at least it will always be the same amount of innacurate if you know what I mean.
I have the sensor placed at the base of the head on the crank case opposite the exhaust port.
When the motor says it's at 250F if I do the water drop test the water jumps off the head so I know it's a roughly accurate reading.
So if it runs a 9 fin heatsink and is ok to run hotter then no probs. I'll try and find a bigger heat sink for it.

All the venom ones ive seen where 20F or more out. I had one myself but sold it because it was just too far out.

333.9F!! Must be a new record. That was with the extra shims and a #7 plug. It must have an air leak but I give up. I think if STS wanted to ever sell more than one engine to anybody, they should really look at improving the carb or whatever it is that leaks.

Check your carb;head button;plug;front bearing;rear cover...if there is any fuel leaking?

It was still making good smoke everywhere. It just continued to get hotter and hotter. Before that run I checked the head button, I sealed the rear plate, carb where it mounts to the crank case, the main needle and fittings for the fuel inlet. When I was removing this demon engine from the car, I noticed that there was some fuel around the front bearing.
If a brand new engine is going to have a front bearing that is unserviceable then I doubt the rest of the HP claims or anything like that are going to be substantive.
If you want it for $100 Mr nightmare it's yours. But no cheating and putting a different carb on it!
As for going to visit the dudes at project ZEN, for the price of a plane ticket to the US, I could buy a number of decent engines that you can actually use easily, not STS ones.
