Hi,
Sorry mate but if you bolt this "kit" straight onto a standard motor you will break something.
The basic reason for forced induction (turbo or supercharger) is not to increase compression or the maximum pressure in an engine cylinder, it is to increase volumetric efficiency (will explain that in a mo) although forced induction is the most effective meathod of upping compression.
If i confuse anyone wih the Volumetric Efficiency bit let me know and I will try to clarify things. :wink:
When a naturally aspirated engine suck air in, it can only draw so much in before the intake valve closes and seals the cylinder. The average N/A engine will pull in around 60% of its volume, so as a result is only 60% volume effecient.
The only way to improve this is to force the air/fuel mixture into the cylinders (forced induction) thus filling them more. the average forced inducted engine runs at onver 90% volumetric efficiency.
If you increase the amount of air/fuel in the cylingers by 30% then as a result you will increase the compression by 30%, which would be too much. In order to keep the final running compression the same, the inital compression (without boost) has to be dropped to compensate.
I think that makes sense. :?
