Has anyone compared these two options? Currently have the RJC plate on a stock plenum but have heard (from a reliable source) that the Hemco alone is better. Of course there's always the Precison too. Would appreciate any input.
 
I remember a few years ago David Buschur did a back to back test on the Hemco and stock plenum. I forget the numbers but I know I was running consistent 12.0s I put on a Hemco and a 62mm throttle body and it went 11.7s i know a few guys on here think it is snake oil but I am a firm believer in the Hemco.
 
Although I don't think that the Hemco plenum is bad, I think they're becoming "old school" as time goes on...I believe that the power plates are getting more and more popular giving the same results...but that's only my opinion...:rolleyes:
