Since it's been refreshed Wayne Park (Race Car driver & mechanic) has the car sorted and running so well that it's now scary fast. His words were it's the fastest 930 he's ever seen or driven and estimated HP at about 500 .. I've had the car since October and the Previous owner knew nothing much about it, he bought it 'cause it looks pretty . The car has a 1.5 Bar spring in and breaks traction easily in 1st 2nd and 3rd in a straight line .. I'm running 98 octane with an additional Octane booster to give it the fuel it needs - Wayne advised me that the car has had a lot of $$$ spent on it to get it to where it is now so spending more $$ to make it slower didn't really make sense.. Give it the fuel it needs and you'll be fine .. But I still have concerns about over boost .. But the car does run VERY well now that it's been tuned properly .. Don't want any blown motors ..
How can you be running 1.5 bar of boost on crappy 98RON fuel in a CIS 930?

That's the equivalent of 93 MON in the USA.

What kind of intercooler are you using?

I'd turn that boost down before you blow that motor. All it takes is a few seconds under load and BANG!!! 1.1 - 1.2 bar is probably safest for a well sorted car on our pump fuel.
