im building a peripheral port motor and was wanting to know about useing a holley 4 barrel.... i know most ppl use a 2 barrel weber type set up or FI, i have only seen 1 holley peripheral port manifold, and i dont remember where i saw it ..anyways i read a few things saying that running a 4 barrel on a 2 port motor would mess with the flow of air.....so more or less i was wanting to know what yous thought about it. coudl i have a manifold built that would flow good? would it be able to make good power if jetted wright let me know what you think

thanks Patrick

 

What part of NC are you in? Carl

 

provided the holley can flow well enough to supply the PP monster, there wont be a problem there.. i think the big issue is in manifold construction... one primary and one secondary need to feed the front rotor and one primary and one secondary need to feed the rear rotor, or you can have a micro-sized air box underneath and just Y split the airstream that flows through the carb. like the racing beat exaust manifold, but backwards and shorter.
did you make the PP housings or buy them? if so, how/where?

edit: just as i replied, i noticed camocarl had 666 postings... spooky.

 

Is it a 12a or 13b PP?

 

its a 12a PP....im doing it my self started on it a few days ago......

i live in Morganton NC.....

so SparkienSuggah are you saying have 4 runners 1 runner per barrel that hook together at the ports. 2 runers per port one prime and 1 2nd per rotor? or 2 big runners that would hold a prime and a 2nd?

 

I'd like to see them after you've done porting, good luck.

 

Talk to peejay, he was using a Holley on his homemade pp. I think he had a lot of trouble trying to make it run properly.

Why do you want to run a Holley anyway? An IDA or IDA style throttlebody makes a lot more sense.

 

thanks ill be taking pic's in the next few days i hope i just got to stop being lazy its cold out and the machaine shop has crappy heat but oh well

does any1 know what the biggest size TB's and injectors ppl are running on peripheral port motors?

 

It would be neat if you could use a stock center iron for the primaries, fill the ports on the front and rear irons, then have the mech secondaries feed the peri-port.
Not neccisarily a full size peri-port, but a size to match the secondaries.
Of course, custom intake.

I would like to see the intake and fuel delivery for this.

 

The old Scoot secondary PP. From what I remember it was using a modified 3rd gen manifold.

 

well for the biggest reason is to be deferent and i like holleys ..... alot of ppl have problems with holleys in the 1st place. I'm also 1 of thoes people that likes to doing things others say wont work or wont work well i came of when a manifold that i beleave will work very well...after i build it and try it i well let every1 know

 

I live in Asheville and have my 12a pp slapped together and ready for install (as soon as I locate a lightweight flywheel)
I am using a weber 48ida.
Look me up sometime

http://www.hogansracingmanifolds.com/ Look in their catalog scroll down to page 4 and you will see an example of a "Holley" style intake for a PPort motor. There are some of those that have been successful with a PPort and a Holley but most just go with a "Weber" style carb for simplicity. Nothing wrong with a Holley if you know what your doing. Personally I would go with an EFI system on a PPort but that's just me.

 

woot woot thanks 13btnos that was the manifold that i had thought of that it would flow the best but a few ppl had said diff i was going to make it and try it any ways! thanks they big help........also what size TB and injectors would you run on big PP motor with a efi system

 

http://www.auto-nomics.com/cgi-bin/s...rt=10850-002-D The bare throttle body is $75 but if you buy it with the TPS and fuel rails I think it's around $250 but don't hold me to it. Give them a call and I'm pretty sure they can help you out. I'd much rather go this route than a carb. And for the injection side if you are pretty good with electronics go the rounte of a Megasquirt or pick up a Haltech F9 and run 2 MSD 6al's through a locked distributor. Cheap and easy setups. Good luck.

 

My mate has a GURU PP with twin 60MM throttle bodies You should hear it. I run 50mm throttle bodies on both my PP's (One is 45mm, the other is 48mm port) and they are matched well to the motors. I personally wouldn't bother with a carb on a PP unless EFI is not allowed. I reckon 50mm bodies would be alright on a 12A PP.

For a big PP perhaps 550cc primary injectors and 800cc or larger secondary injectors

 

do you have any idea what mm ports your friend is running with dule 60mm throttle bodies its it a 13b or 12a?


now we are getting somewhere

 

If you stick with carbs...go with the one on the left!

 

thats a nice crab...but im going togo with a demon 4 barrel....if i wasint going to go 4 barrel i would go EFI...but so many ppl are saying the 4 barrel wont work well that i have to prove them wrong and do something diff what fun is doing the same thing as every1 else just caz its most populer..got to be diff think out side the box and knew know maybe come up with a good idea

 

well this is the manifold its more or less the same idea i thought of tell me what you guys think about it...i think it should flow very well

let me know what you think

 

holley FTW!!! WOOOOT!

 

holy ****!!!!! thats nice

 

I prefer this Holley pport manifold. It sure looks a lot easier to make, and both rotors share a plenum (which is an idea I like). This is how I intend to run my Pport. Holley manifold with a carb and a nitrous plate kit. Easy stuff.
