So after much discussion on this and other forums a few of us have come to a conclusion. None of us have ever seen a dyno sheet of a bridgeport or for that matter a peripheral port 12a or 13b that is not turbo'd. If anyone has sheets if you could post and a slight description of your setup that would be greatly appreciated. I am planning on building an engine soon, and i'm trying to gather ideas and information on what powerband I want because it is for my full time auto cross car.

 

mazdatrix has numbers posted

 

We've all seen the numbers. I'm looking for actual dyno sheets.

 

Not much looking apparently, the newest thread in the *gasp* dyno forum here is a n/a 13b pp. Heres the link for the lazy



And another from the same place...

 

cool I found those 2 peryports, but there are still no bridgeport results anywhere.

 

i saw one dyno in person, the dyno sheet looked like a piece of paper with lines on it.... it did 231rwhp@9600 which is all the rpm the dyno will go.



it was an old school 13B, bridge was into the water jacket, but with as mild a timing you can get (3 finger...), think of a high lift shirt duration cam. 9.7 rotors, aluminum flywheel. he used an RB holley manifold with i think a 750 carb on there. exhaust was RB road race header, to 2 really long (40") 2.5" glasspacks into 2 dynomax mufflers.



he spent some time on the carb, so it was very driveable, and with the gsl-se trans highway mileage was in the mid 20's.



it was in an rx3, if it matters

 

I will be visiting the dyno soon. i'll try to video some footage and have some better results then last time.. Im changing my fuel over to methanol, so i need to re-map my haltech..

 

u used to use race fuel?

 

I'd head over to bcrotary.com. There's a few guys with PPorts (12As I believe) and plenty of bridges too. I remember a few dyno sheets getting posted too.
