thoughts about 18G

[scheides]

I doubt even an 8cm housing could make that happen; I had a Super20G on my old 1G, and it spooled 20psi by about 3800 at the latest, and that is with a 10cm housing. What is your base timing set to?

I once spoke with someone who was trying to fight knock & run high boost on pump gas w/ a scm61 (which should spool on a stock motor by around 4500, right?). Anyways, he had his base timing set to -5 degrees or more and it didn't spool until like 5500 or 6000 rpms.
