I consider Peripheral ports to be strickly track, I know some people with them doing high 11s in quarter miles non turbo.

i need to build an engine for my one rx7 which is essentially a track car for hillclimbs and road racing. i have considered the bridgeport route or the p port route, but i am unsure which way i want to go.

For what it's worth, I made 216 WHP (mustang dyno) on almost stock ports, stock intake manifold (modified) stock NA injectors, Racing beat headers, presilencer and dual Dynaflow mufflers on factory Y pipe. There is nothing wrong with the factory ports at all (they only need a little cleaning up). You could do better with a bridgeport, but could you average 25 mpg, idle at 700 rpm, go through drive-throughs without having to shut your car off, and loan your car to friends?

do i want to do any of that? No. especially let anybody drive my car. if they cant drive it bridgeported then they dont need to

lol... i dont think that was his point.

i need to go fast.

Who want's to go fast?

Go P-Port if you can.

FWIW in turbo app's - Brian does not like the excessive overlap that bridge or p-ports give. Open the exhaust earlier, close the intake SLIGHTLY later. A lot can be gained by porting, but not touching the ports :suspect:

You can get 450whp out of a half-bridge with a 60-1, get the idle you want with milder characteristics.

Seriously, don't overdo the port work with a modest power goal like that.

the biggest thing for me on pports would be keeping my coolant where its supposed to be. My friend Pete used Devcon (or something like that) to fill in the coolant passages, but it still had tendencies to leak either internally, or externally.
