Is bridge porting better than peripheral porting? What is the difference between them, and where is a good place I can get it done?

 

Bridge port:



Peripheral port:



There is no "better" port. Both have their advantages and disadvantages. If you intend to make lots of power on a side port engine (400HP +) then a bridge port is the way to go but keep in mind that you end up with a 1200-1500 RPM idle, questionable low end (depending on tuning) and an engine with a wonky vacuum signal that is hard to tune.

Peripheral ports are another story. You can make huge power but the low end is even worse (midrange is better then side ports) and again you're going to have that 1500 RPM idle.

Most normal people don't consider peripheral ports streetable (I am not one of them). Many people don't consider bridgeports streetable but I am not one of them.

 

So, I should probably go street port then if I want more torque?

 

If you drive it a lot, then a streetport is a better option. They have better low-end torque for around town driving. Bridgeports can be streetable, but it depends on your definition of streetable. P-ports are the same way. The guys at pinapple racing have daily driven p-port engines, and even driven one crseveral thousand miles while hauling a trailer. Its all about how you tune it and how careful you are with the setup.
Bridge and p-ports also are quite loud.

 

If you have to ask, then a streetport is your best bet. Honestly you can make huge power on a street port (or even stock port) so unless you want to get crazy, then you don't need to bridge.

I personally consider peripheral ports streetable. In fact any day now my peripheral ported housings for my GSL-SE should be back from the machine shop. But a PP engine is definitly NOT for someone who needs to ask.

 

not to mention, from what ive read. you cant just start drilling holes in the housing... it takes some prep to make a Pport last any reasonable amount of time. Like a balanced rotating assembly to make use of the power. They say Pp engines make no power till north of 6,000rpm and keep going till 10-12k.

But dont take my word for it... Im in that group that wishes I could spend money on that... 300+hp NA is sick...

 

do a half bridgeport

 

Thats half assed. You'll still get the blowback into the bridge, still lose the lowend, it will still "brap brap"

Go full or go home

 

hey aaron cake how much they charging u to do the housings

 

yeah go fullbridge.

I went halfbridge and wish I had gone full.

that said, my halfbridge is pretty streetable. Not that loud, lots of power, not a lot of torque but enough that it's not hard to drive. Can still putz around town at 2000rpm without any issues, but it doesn't seem to like 5th gear below 55mph now.

 

Umm, I'm pretty sure that this guy has a non-turbo, not a turbo.

 

You mean peripheral port housings? I don't sell them.

Most machine shops can do it for a few hundred dollars. Most of the vendors sell them for about $700-$1000 each.

 

I like Peri-Ports!!!
