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

 

That's awesome!
love the Fseries engines

 

why wasn't a mandrel bender used?

 

Because Valazquez and sons' 80 dollar piping special is crush bent only.

 

3" Intake or 3.5"

 

Thanks for sharing, as always mikey.

 

Boy that ebay header really shows it's quality and design in that final run from 90-104. Thanks for posting Mike.
