parisifal, I don't like the way you saying. I dont' have to say much. Below is the quote from Maximum Boost by Corky Bell. PLEASE READ and do reseach about HIGH compression on engine. The book can't be wrong
And I repeat, HIGH compression engine, example FSZE, can be TURBO !!!!! Honda GSR turbo is an example !!
Quote:
" In outlining engine performance desired, the first decision is the compression ratio. Comperssion ratio affects a large number of performance and driveability factors. Throttle response, economy, bhp per psi of boost, and that intangible, sweet running condition associated with engines eager for action are some of the performance factors determined in large part by the COMPRESSION RATIO. DO NOT BE HASTY TO LOWER COMPRESSION RATIOS JUST BECAUSE MOST OEMs LIKE TO DO SO. The proper compression ratio for the job is determined by lengthy thermodynamic calculation and comprehensive testing. All that good technology has its place, BUT USABLE NUMBERS CAN BE GENERATED BY SOME EXPERIENCE and will hold for most general applications. The two largest influences on compression ratio are BOOST PRESSURE DESIRED and intercooler efficiency. Fuel octane certainly plays a big part, but we are usually limited to using commercially available pump gasoline."
And again, plz start with lower shot of Nitrous before you go for 50 and above. Good luck.
peace.
