Here is an Ap1 S2000 engine with the stock ecu on the following modifications.

2.5 crush bent exhaust
Short ram intake
Ebay 99 dollar header


Run 1 is with the stock ecu
Run 9 is with an AEM ecu tuned.
Run 17 is with an AEM ecu tuned with a Velocity stack in place of the cheap Spectre autozone intake filter.


Runs are in MPH because of RPM pickup issues.

And for your amusement this is the chassis it was in

 

thats hilarious. though once you close the hood and add heat soak to that intake. im sure numbers will fall back.

 

Awesome! Spectre filters aren't crap, they hold their color ages longer than aem filters could lol

 

Hood was open for all testing. We did close the hood and heatsoaked the intake with the ECT's nearing 190 constant and ECT's at 105ish, results were only down about 3whp
