I see so many absolutely HORRIBLE bits of information flying around forums these days... Moreso on other forums than here, thankfully, but still...
Let's see if we can compile a list of common myths as they relate to tuning (cb7s specifically, though Hondas in general, or all cars if it applies)
Someone recently PMed me about making a forum about this, and I forget who it was! I think a thread would be better suited, at least for now.Whoever sent that PM, step up and take credit
So, on with the list!
1. Hollowing out your catalytic converter - This does not make power. If anything, it causes a loss in power. A hollow cat creates turbulance and a place for the exhaust flow to stagnate. A free flowing exhaust only works when the gas velocity can be kept at a decent level.
2. The CB7 is too heavy for any engine smaller than 2.2L. - Bull. Granted, "there's no replacement for displacement"... But in many countries, the CB came with a 2.0L engine, or even a 1.8L engine (even carbureted!) Sure, they aren't rockets, but they move just fine. The engine size is a common argument against B series swaps. A B18 would move the CB7 easily enough. The engine size isn't the reason why the swap isn't practical... it's the cost of fabrication, versus the direct H and F swaps.
3. You can't boost an H22 because the compression is too high - This is only partially true... The main reason for this is that high compression significantly decreases the threshold for error. If you don't know how to properly tune a high compression turbo engine, the chances are greater that you will do damage. Lower compression gives more room for error.
