Using an SC12 supercharger in a blow-through setup is a BAD idea (I don't know how many times I've said this). If you think a little BOV is enough to vent excess pressure when the throttle is snapped shut, think again!
AFAIK the rpm limit for an SC12 is around 10k rpm. The SC12 is a positive-displacement pump which means it displaces exactly 1.2 litres per air every revolution. So, imagine your at max revs and you lift off the throttle - all of a sudden, you have 12,000 litres per minute (approx 420cfm) of air with nowhere to go except out the 1" outlet of a BOV! Hmmm, what's wrong with this picture?
Running fuel through an SC12 is no problem, plenty of people have done it before. Just think of how many old-school supercharged V8's run fuel through their roots blowers, no problems there either!
