How will more compression react?

[streetknight]

going in the 9 to 1 range. How will this affect the alky side of the equation?

Can I still run the same timing and boost?

You will have to drop something a little, timing or boost. But it will probably make the same power with less of either.

I would start with not making any changes at all and seeing what happens. Obviously don't pound it right out of the gate..but sneak up on your max boost setting and see when knock begins.

If it starts knocking, which it may, you can try to add more alky and pull out some fuel to maintain afr, and leave all else alone.

If that doesn't work, then the simple thing might be to just back some timing out.

Whatever you do, make one change at a time so you can backtrack.
