Just put some 10k boost in my Williams. The revs rose and dropped when it was going in. Quite a bit of white smoke came out when it was going in. Drove it after and a big puff of smoke, then no smoke. Result - Now have a large induction roar on acceleration and the exhaust pops alot more between changes and when i ease of at high speeds. Whats changed in the engine? Are these effects good?
