Im looking for a someone/place to port my accel runners and and manifold. i would like to siamiese my accel runners port them to 1.75 all the way through and gasket match them. I just ordered afr 180s and i would like to make sure that my tpi can breath to 5500 if possible with out welding. I didnt want to send them to extrude hone, i started one runner and I dont have the knowledge/experience to do it properly. If anyone is intersted please pm with prices.

His work as at the bottom



(Im not sure if this is the right forum but it said tpi porting.)

 

anyone?

 

Are the Accel runners the tube type? We have a place locally that has done porting for us. www.j-performance.com is his website. I'm just having trouble visualizing the Accel runners.

 

They look like the bottom of the edlebrocks they are tube type but they are cast .

 

I remember those accell's. I don't think they sell 'em anymore, but they were cast, and they did respond well to porting. Kinda like a full runner version of the super ram runners.

 

That's. What I hear so that's why I'm trying to port them

 

OK, no problem then. A little welding and the runners can be siamesed if you want and/or opened up. If you have the money Dr. J in the link above can do it for you. I think he has two levels of porting the intake manifold itself. He did one Accel intake manifold recently that flowed around 330cfm. That will flat get it done and give the AFR180 heads all the air they can handle. If fact the heads will be the restriction.

 

you dont need to weld them for them to be siamesed they are cast I will take a picture

 

I think what he means by welding is that to fully siamese them, from plenum to manifold, you need to cut 'em open, port, and reweld them closed. Most people just get as far in as they can, but they're not fully siamesed.

....or I could be wrong.

 

ahhh yeah i dont want all that done to it just alittle bit more then the slps and with bigger ports

 

What I was refering to was the "dip" between the runners. If I was going to siamese them I woud fill the "dip" with aluminum weld and then make the runners into one big oval for the siamese portion.

 

i thought about that but i actaully have slp's in my garage and i dont want to use them i like the look of the simi seperate runners I actually sent my manifold and runners off to a member on the covette forum he is down in southern ca. I will post pics as soon as i get them back.

 

If anyone is looking for. Porting services for there tpi. Pm me for his details

 

here is his work looks awesome i will post my manifold next and the plenum he did

 

the ones on the right are accel runners that he did and the lefts are slp runners

 

 

Thats some nice looking stuff you have. When do you think you will have it going?

 

well i still need to take the 305 block out of my camaro then get the fly wheel over to the machine shop so they can balance it. I have a pretty much stock rebuild on the bottom end with forged pistons and 10 to 1 compression.
Then I have bosch 3 24lb injectors with afr
xfi 268 cam
ported and siamesed runners
ported manifold
ported plenum
afr 180s
I am after the same amount hp as you are hopefully atleast

 

dspencer24, What gaskets are you using? I've started porting my SLP runners and was jus wondering what gasket you'll be using as my runners will ported like yours. Thanks

 

Im using accel gaskets right now, for the top gaskets to the plemnum I just cut the middle out and rounded the edges to match. Ill find you a link for gaskets

im pretty sure these will work for you

 

How much did it cost for all that? Can he port stock runners or is it better buying slp and porting them? how much hp can you get by porting the intake, runners and phelum?

 

Thanks for the words Don enjoy seeing builds like yours...look stock but run hard. Love sleepers.
(Never was good at taking those "glamour shots" lol)

Lots of neat builds going on here have to hang around, Camaros are my first love.


Pic of your base I dug up. Camera angle makes things look funky sometimes

Runners were siamesed 2 inches in if I remember right.




Looking forward to seeing what its putting down once running.

Nothing really to port there unless you cut them up. Cost/hp go aftermarket.

 

ill be calling you on doing something like don did ..what runners do you like to port ?? as&m or accel ?? also is there a certain base you like ?

 

You cannot port as&m Or tpis. Only Edelbrock, accel and slp

 

cool, i have the accel's.. just got to figure out what base to use ..

 

What base do you have

 

Ron does good work, looks great.

 

yeah im glad that I went with these i like the look personally i lot better then i do the slps that i have

 

Can this guy port my tpi base for me? Let me know

 

lol ask him its cruisinartvette there is also 385in2005 and there is a couple of guys down in southern ca as well

 

is this a company or just a person doing this type of porting? Thanks

 

they are people lol

 

385in2005 is siamesing my runners alittle more and gasketmatching things cruisinart did a good job but he had alot of time in my runners i got my moneys worth.

 

We just finished welding up this TPI base and runners for the full competition porting package, Siamese runners and raise intake ports I'll keep you guys in the loop with some picture updates and flow numbers.....Allen,Don,Kevin I know you'll be watching

 

haha wow thats a lot of weld I am intersted to see a finshed product and see how nice you got that weld to look. I bet that super ram is gonna flow

 

Jeebus!LOL


Question...if you have a smog issue where you have to use the TPI or are just doing it to do it why not just use a miniram or an intake that already has a short runner?


Like to see the results, regardless. Looks like fun.

Tell us about the build its going on?

 

he is from cali so there is smog. I wish we could use a miniram out here leagally

 

"why not just use a miniram or an intake that already has a short runner?"

One reason would be you can customize the total runner length to take advantage of "wave tuning". The 4th harmonic is worth 4%. The third harmonic worth 7% and the 2nd harmonic is worth 10%. If going for the 2nd harmonic you will use all three boost rpm ranges. The stock TPI uses the 3rd harmonic range for its boost. Most are well aware of the boost that creates. I might add that the LS1 type manifolds also use the 3rd harmonic wave. One more aspect is from I have read it is best to have the runner volume roughly equal to the volume of the cylinder. This helps in the added boost in flow from the kinetic energy from the ramming of the air mass into the cylinder. Again check out the LS1 type manifolds. If done right and with a good exhaust you can create up to 5 pounds of boost.

Bryce that looks real good. I am having my welder add some more weld beyond the fuel rail posts. When the machining and welding is done I will get my manifold over for you to do the porting.

Guys we have a car with a Super Ram recently done by Bryce and I do not believe to the extent of the above photos but the performance was well above average. Everyone attending the dyno session took notice. The results have been posted on this forum with Dyno Don the originator of the post.

Edit: Here is a link to the subject. An interesting read and talks about total runner volume.

OK, so... you're raising the port toward the head end of the base? What about the rest of the port? Are you adding epoxy to the floor? I don't see a point in this.
Lingenfelter proved years ago that this has no benefit.

 

That manifold will most likely flow in excess of 320 CFM and still over 300 with runners in place.

 

I don't know what Lingenfelter did but we have proven it does have benefit.

 

320 cfm can be done without welding. Using a TPIS base.

 

The modification and testing Lingenfelter did was to a long tube TPI setup.
I have the article if anyone is interested.

 

Post it up so we can view it

 

No point starting with anything from them if you're going to port it yourself. Save $100+ and buy it straight from Edelbrock.

 

Yes, true. Same base.

 

What do the factory bases flow after they have been ported?

It made some improvement when they swapped on large tube runners. They aren't clear as to if they used the large tubeS with the welded intake or just a ported intake. This article was written before there were any production large tube runners available. You should see the picture of the runners they made! Square tubes!!!
