Thought you guys would find this of interest.
Various minor mods and tweaks along with a MOTEC ECU were used to gain some HP. I think that others have already noticed the extra rich WOT characteristics of the S2000. BTW, they seem to have rather high chassis dyno loss factors. This is not necessarily bad since any relative improvements should still carry through. It would be nice to verify or refute these claims.

I can believe the improvement in the motec.
But I find the exhaust improvements hard to believe - what you have to remember is that their baseline stock s2k run is not off the same car.
The car came in w the mufflers on already.
To be accurate one should just look at the motec improvements, which are very susbtantial

Isn't that absolutelybloodyamazing - a dyno recorded power output of 195hp at the wheels on a Dyno Dynamics - and all from just 2-litres of NA muscle?
They said they started with 153hp at the wheels!!!! I never seen a S dyno so low! Though it great for starting at that as a base line. Then quoting stock real readings.

BTW guys MOTECs aint cheap but it is the way to go, much better value than mugen ecu.
Also note that they used a dyno dynamics dyno, this allows easy ecu tuning as you can hold at different rpms and tune.
Roller dynos (which will give a higher notional hp reading) will not allow this, ie. yu need to do a whole rpm run.

Maybe the dynos run backwards down under?
They don't say how many miles were on the stock car and the test car but I am betting the test car was well run in and the baseline car was still tight. I think that accounts for more power gain than the exhaust. No one has really picked up any significant power with any of the exhaust systems on this board, not like this guy is claiming anyway.
Be interesting to see if they melt some pistons down the road. I am betting Honda wants it running a little rich for a reason, most probably as a safety margin in case the injectors get a little dirty or cold winter running, or some other conditions that naturally/unexpectedly may lean out the mixture.
