well I a about to build a P-port 12a for racing use only. I was just wondering what kind of sound do they make and how loud is it? all I can find is vid/sound clips of bridge ports. what supporting mods do you recommend of this type of port? Also is there any pages on the web about the P-port? any help would be appreciated.

I'm not sure if my experience is the norm, but I have a 13B PP race engine installed in an R100 Coupe, and the engine note does not resemble the normal "brap-brap" noise the others make. I have a recording of the engine at idle which I will try and post later.



Cheers,

hard to put into words, its not like a bp. we got to hear the 79factory racer this summer, sounds very good.

hi,



Can't seem to find the stationary video but here's a link to a video with the car in full flight down the main straight of Eastern Creek International Raceway. Sorry for the distortion, but the digital camera couldn't cope with the noise level.

thanks for the clip. it sounds wicked. what else did you do to the engine in the R100? what kind of power/rpm do you run?
