The results of our test are very puzzling, indeed. I shared the dyno plots with AEM and they were quite surprised. When Shawn Church saw it, he was shocked as well. It's just not the way it's turned out in his independent testing.
In any case, we can't complain about 209 hp to the wheels. Consider this - if the dyno plots would have shown the typical 8+hp gain over stock, we would have been looking at 215-216 whp, which would have been inexplicable for an otherwise stock 2.0L S2000. But something tells me that there are other things at play. One theory I have is that the V2 possibly "fools" the engine computer into a more optimized fuel strategy. And since we didn't reset the ECU on the dyno, perhaps even the stock intake system was able to benefit from this optimized ECU calibration even though it may not quite flow as well as the V2. Yes, it sounds far fetched, but what else could explain our very high baseline number? I suspect AEM will be getting back to us with their own theory as to what could explain this, but for now we have our dyno test results.
|AEM V2 Intake System for Honda S2000|
|Test Date:||6 August, 2004|
|Odometer reading:||19680 miles|
|Peak measured HP Gain:||1.8 hp|
|Peak measured torque gain:||5.4 lb-ft|
|Total Weight:||6.5 lbs (4.0 lbs lighter than stock)|
|Solid power gain(?)|
|Excellent quality and fit|
|Is it really only a 2hp power gain(?)|
|Installation requires some light cutting for proper clearance|
|It's hard to argue with 209whp on an otherwise stock 2.0L S2000 motor, but the icing on the cake is the menacing growl, particularly from 6000rpms onward|
