One Mod at a Time
I keep talking about my headers, headers, headers, but reality bites. I don’t have the time to do it anytime soon. John asked why the hell I still even had the factory smog pump still installed. I said I was going to take that out, cap the intake manifold, and install the headers at the same time.
He shook his head and reminded me of the ancient one modification at a time rule. You can change all kinds of stuff at once, but then how will you know what actually did the trick?
Besides, he egged me on it would only take five minutes to bypass the smog pump. It’s just an air pump that runs off a belt drive that shoots hot air from the engine back into the exhaust to make it “cleaner”. Bullshit. We capped off the intake with a plumbing fitting, plugged a vacuum line so no leaking, took off the belt so I wouldn’t rob the .00000000000001 hp that pump was pulling.
To be honest, you can actually feel the more linear exhaust flow out of the puny 1 7/8” pipe, and just as John had predicted, got rid of some minute backfiring that I had actually grown accustomed to. To be fair to the environment though, I gotta admit you can smell the exhaust now, and it probably doesn’t help that my front carb as usual is starting to run a bit rich again.
