Emmissions vs Horsepower:
I just wanted to throw some information your way. Several people say removing the Smog system only nets one or two HP. I live in Phoenix! As soon as I had my truck (86 Chevy C-20 4speed registered as a classic) I wanted to remove the Emissions, but first I had it Dyno with 80 Hp at the rear wheels. I removed the pumps and the tubes that fed into the exhaust manifold. No wonder these trucks were bogged down. I pulled the exhaust manifolds removed the power robbing tubes, my
friend welded bolts over the holes in the manifold. Once I got it back together I immediately noticed the increase in power. So back to the Dyno I went. This time 105 Hp at the rear wheels. Once you have it apart and see how much power is robbed by restricting the exhaust, unbelievable! For you Phoenix guys Charlie Echols has the Dyno. 25 Hp for just a couple days work, was well worth it. ![]() ![]() |
