First, overboost switch doesn't have nothing to do with revs. It only senses boost and not RPM. Once the boost is over 1.1 bar (roughly) it will cut fuel.

Second: Car makes max power at 5500 RPM with stock cams. It also has same weak rod bolts as OEM Carrera. You know, the ones that stretch at high RPM and make a nice hole in the case and your wallet.

Third: as far as I know, RPM-limiting function was somewhat flaky for earlier cars and would creep upwards sometimes.
Manal says: 6000 RPM continuosly, 6500 RPM in brief emergency. You said you revved it to 7000+ RPM?

Stock boost is 0.7 bar. Stock CIS and engine will tolerate 1.0 bar on a nice cold day...if you are pegging 1.5 bar your wastegate is either stuck and overboost switch is disconnected or there is something wrong with BOV and you have excessive boost peaks on overrun. First is much more dangerous than second....second will "merely" blow your gaskets from intake system.

It seems like you are on your way to produce nice long rebuild thread on this forum pretty soon.

Get my point?
Thank you for your time,
