Anyone else on this forum has the Gen3 SC Aluminator short block 9.5:1?

I tried using the search function and its coming up with no results. I have one currently being installed. How is it running ? Who tuned it?

With the 9.5:1 CR, it will feel a little doggy until the boost starts cranking in. Just be aware. Dyno #'s will be 50-70whp less than a 12:1 boosted setup with similar parts/tune etc.

Hey Cory, he's on a gen2 so it's dropping from 11 not 12.

Also, if the tuner knows how to calibrate the torque-to-load and load-to-torque tables then there will be no difference in part-throttle torque response.

There are at least a couple of gen3 9.5/1 aluminator dyno results on youtube if you care to check them out.

Well, since most people focus on that big dyno number, it was just a warning mostly.

Without a doubt, lowering compression reduces efficiency of the combination. So, in order to make up for it, the boost will need to be increased. Dropping from 11 to 9.5 will lose on the order of 40 hp, so I believe and additional 2 psi will make that back up. You'll find you can run a good bit more timing as well, before knock sets in.
