DIY Intake / MAF Housing Testing

Um.. IDK, knock, IAT's, etc. etc.

He could also determine how aftermarket exhausts cause blown turbos, ROFL.

Um, not really gonna be much different from other SRIs. Trims could and can make a big difference. That's why CP-e and Cobb are so careful to make there's as close to stock as possible.

Agreed, but:

Corksport Press Release "Short Ram Intake"
Though not widely known, under boost the short term and long term fuel trims are not used by the ECU. This alleviates concerns of an intake system causing unsafe air/fuel ratios due to abnormal fuel trim adjustments because an engine is most likely to fail under boost during hard acceleration.

So what I get from that is, although the LTFT's are important to know, there ARE other things to consider when designing the intake.

Looks like a nice cheap alternative. I like CP-E's design of the machined straightener so there isn't any glob of weld inside of the pipe. (not trying to be biased, I don't own the CP-E for the record) And did you make up a batch first, and now are going to test it?

i have one lone test piece

thanks to Anna-chan, we've been able to log some miles on the unit. So far, it performs as it should with no hiccups. Weather was not conducive to alot of heavy driving (snow, 25 degrees) and my laptop was not cooperating. However, i'll get it working or steal a dash hawk and log the fuel trims, etc for people. After a few drive cycles and about 30+ miles of driving there are no problems or check engine lights to report.
