What pistons did you use to get a compression ratio around 8:1 and still maintain a good quench in the comb. chamber? Kerry, I would assume you researched this for your procharger project?
I've been told that the dished pistons, like in the 455s, don't have any quench (or not enough to matter) and I've heard that boosted engines do well with dished pistons. Putting 2 and 2 together (and probably getting 13!) I'd guess that quench isn't as important in a blown engine. Now someone who actually knows can answer! :laugh:
I was thinking along those lines figuring it was possible that the added velocity of the charge entering the cylider might create enough turbulence to negate the need for quench. But then I thought that might be a stretch. I then figured that the flat all around the perimeter of the stock type piston might make enough quench, since that's what the turbo v-6's used.
I was told the same thing as Alan about the 455 pistons. I would have to assume that the huge dish in the blower pistons means there is very little quench. Must not be important.
