Serious turbo tech. questiuon...
Ok this may belong in forced induction or off topic, but here it goes... I was visiting with my friend the other day and we were talking about cars and turbos. And this idea hit me... The problem with high boost is detonation caused by heat from either the hot turbo gasses or the high compression ratios,, So i was wondering... If you droped the compression ration "CR" down really low like 6:1 or 7:1 or lower and boost the helll out of the engine would it not make more power than less boost at a higher CR? or is there some magical number where the benifits ware off? Or are there other problems? like blowing head gaskets... or melting the turbo(s)? Maybee this is already being done and i have just never noticed it.. But it has been buging me for a while and i thought you guys may know... Please give me a definate answer not an I think... or if it is an i think tell me why you think it is true..
Thanks alot! :thumbs:

Lower compression ratio will allow for higher boost but will make the car a slug in the low rpm area before the turbine gets enough energy to power the compressor.
Also, the biggest contributor to detonation is the temperature of the intake charge.
If you're realy interested in the in-and-outs of turbocharging, I recommend you purchase the book called "Maximum Boost" by Corky Bell. ISBN 0-8376-0160-6
