Gen3 Low compression Aluminator

[hennessyVV]

Hey,

Looking at a gen3 low compression 9.5:1 aluminator and running n/a for a while until if/when I add boost. Any issues going this route versus going with a high compression 12:1 gen3?

The only thing I can think of is you’ll be down on power approx 10-1/2% relative to the 12:1 engine. Conventional thinking suggests a reduction of around 4% for each full point of compression drop.

And bonus…you can drive it on regular gas! 😁
