13B Peripheral Port LOUD!!!

car show. Car is a 83 Mazda GLC. It was VERY VERY LOUD in person. I
couldn't even hear him hitting the rev limiter
Turbo Peripheral Port Start-up and Idle
To the Youtube 'tards: This was a quick first start up video before
everything was assembled. The intake plenum, tubing, and coolant lines were
installed after the bugs were worked out.
Peripheral port 13B idle
Homebrew 13B at idle; fabricated ports, header, intake manifold, etc,
breathing through a Weber 48 IDA.
Trying some tricks with porting and header design and it only fired up for
the first time about an hour ago, so I have no idea of power output, and
very little desire to make unrealistic guesses.
Defined Auto Works semi-peripheral port
Semi p-port 20b nissan revving with open header. The car was running open
header for a car show Defined Auto Works was hosting. Please pardon my
shaky recording it was very loud and one hand was covering my ears :)smoke
is due to 1:1 premix ratio and a one year old tune. Defined is a fantastic
company and for more info please visit their site at
