Hey guys I should probably know if something like this already exists given I've been in the S2k community for such a long time but I've never found one centralized place that has actual data for "performance" mods.

Obviously we can google (often pointing back here to old S2ki threads) for a specific part, but do you guys know if there are any resources with data comparisons across multiple parts of the same category? Example, like comparable dyno charts for intakes, headers, exhausts, HFC, test pipes, etc?

I know many of us (myself included) have long parroted the "bolt ons do nothing for the S2000, all the factory parts are perfect and flawless", but to be fair that isn't strictly speaking 100% accurate. Changing anything about the air coming into or leaving the engine does alter how it runs obviously - and it would be handy when people ask to be able to actually provide data to show the exact impact that a given part has.

Just curious if anyone knows of any compilation of data points for stuff like this?
