Every car is different. The only way to know for sure is experimentation, preferably with a dyno. I've run both and like the Bullets better, but I don't have any proof that they make me more power. The did save me about 12 pounds though which may be a consideration to you. But there are guys with the 2-chambers that run quicker than me so that could be a consideration as well. Either way, we're not talking about mega differences in HP.
As far as Bristol goes, it was par for the course this year. We went out in the semis again. Out of eight races, we've made it to the semis five times and finals once. Unfortunately, semis don't pay the bills!
