Turbo pressure

[Berging]

Whats the maximum turbo pressure on a stock engine?
Yamaha rx1 03

That question depends on the fuel you are running. If you are running 87 R+M/2 octane then the pressure will be very very little...
Detonation is what typically kills a stock engine, way before parts break from the added HP stresses.
The better the fuel, the higher the boost just like any engine.
Also the condition of the stock engine, too. If it's sloppy poopy worn out then it probably wont handle as much as a fresh "stock" engine...

I'm going to run it on 98 octane standard gas here in Sweden

98 octane in Sweden, Norway and the rest of Europe and Russia Equals US 93 octane Premium.

5-6 lbs at the most, but I would not garantee it will live. You need to install a head shim or low compression pistons to be able to run higher boost.

Okej thanks

My best Guess for a head shim would be MCXpress in Sweden.
