Maybe if you really understood dynamic compression ratio, I would take you seriously!


Without knowing anything about your car. How would anyone know what you might need for a SLR?


I will need even touch this.

Lets look at Dynamic Compression Ratio a little closer. It is based on engine parameters and IVC. So unless you have done something to have these change once the engine is running it is really now static. People look at Cranking Compression PSI and running cylinder pressure and say see see the DCR has changed. No what has changed is the engines VE / mass air flow. There have been OEM manufactures that actually call this trapped CR and listed it as an engine spec.

Let’s not! Start another thread about meaningless DCR. Meanwhile this thread is about rear gear, more of which the OP needs.

So peak HP is @ 6700 RPM and he said he is crossing the strip @ 7100 RPM. So just how much rear gear would you like him to run?



As I, and other have said he needs a 3 speed trans.
