alot of people say it cant be done but here it is...........i just bought my brother rx7 which i ported a while back ....it is a 6-port bridge port .............



secondary plates are not ported except for the bridge ports



primary plates are lightly ported and brigde

 

I've done a few fully bridgeported 6 port engines. I also bridgeported my Rx8 renesis engine. It's my daily driver. I really like the bridgeported 6 port engines. They have some serious potential. many people just disregard them.

 

the car drove really strong all the way to 4500 rpm then after that it dint have enough fuel ..............i used every thing stock with a modified flow meter and 550 on seconday ..............

 

how did your fully bridgeported 6 port engines run have you ever dyno one

 

no dyno results. just a video of the 87 bridgeported rx7 vs a 91 turbo II in out local street drags. the bridgeported rx7 beat the modded turbo II. A friend of mine dynoed his 6 port bridgeport rx7. we are not happy with the results. We had some lost of power. best hp was. 180rwhp through the mufflers. he found some problems with the exhaust sytem in his car, soon he will dyno again.. I am lookin g for 230rwhp..

 

look at my pics what do you think i should do to improve the preformance and power

 

connect the dots. make the eyebrow larger. spend some time porting the back side of the opening of the port. (inside the runners) if you make the eyebrow larger, your going to need a differen t apex seal. I use atkins 2 piece 2mm apex seals with oem apex seal springs. works great. I could go on and on about how you could improve your ports. Are you bored? this could get long.. today is sunday. I guess we could write a little.. go ahead ask more specific questions..

 

i currently using atkin 2 peace apexseal with one long 3rd gen spring and its been working good what do you suggest for porting on the actual ports ill send some pic in a minute

 

so why BP make more hp than SP? is it open early?



what additional support mod need to make it work?

 

what should do some thing like this
