The compression is going to be really really low as stated above. You would need a blower or some extremely steep gears to compensate for the huge power loss. PS the cobra compression is 9.85. There are many sources that say 9.5 and many that say 9.85 just clarifying that the gt has much lower compression.

So, it would actually be a loss in power, rather than going with a full pi swap?
