Hi, I've been using fuel injection (Enderle Bird) and methanol for many years but I've never had the opportunity to do a supercharged application until now. We've got Duster bodied tube chassis car that weighs right around 2600 pounds. Loose converter, hopefully it's appropriate for the situation, and we picked up a stripped 671 and an additional Bird with the "K" series barrel valve. It's been suggested that it'll need to at least be respooled or just use the cube. We use iron 440 Block, bored and stroked to 500" and Stage V Hemi conversion heads. We'd like to see some low 8s and maybe an accidental 7 would really make my life complete.
I understand that a good blower cam, like a good nitrous oxide cam, is rather specific to supercharging. We have a very aggressive solid roller that I need to see what the specs are...maybe it'll get us by.
My first question to the blower guy was "what compression ratio should we use?" He said that with methanol you can go all the way up to 18:1 but he suggested we'd maybe want to stick around 12:1 and start by spinning the blower 25% overdrive. Fine with me if that's correct.
So those are the question I need to start with, you guys may need more info but I need to start by know what compression ratio will be the most friendly so I can get pistons and rods ordered. We're going to need lots of parts and we also don't yet have a blower intake. So if anyone has some good used stuff we can use, let me know.
Thank in advance,
Wayne
