I picked these up two days ago for almost nothing. I think I am going to sell my SLP runners, and give these a try. They really impressed me. Take a look...

 

Another view...

 

they look pretty ruff

looks like someone simeased<sp> the stock runners by welding a peice of alum in the middle of em.

These are what I have now... unported SLPs. I'm sure if I were to cut these open, and do the same as the other runners, these would probably flow more, but I don't have access to a TIG welder. I really don't have the time right now with school to start another heavy porting project.

 

Here are the SLPs on the inside...

I am pretty sure that those were stock runners which had been worked on. While they aren't all that pretty ( or clean ) , I want to give them a try and possibly compare them to the SLPs before I sell them. I'm aware it will probably sacrifice low end, but the difference between them seems very massive to me.

By the way, there is an old post titled runner glue in which they did this exact thing to a set of stock runners. Last time I read it, the runners have had 4 different owners, not sure who was the last to have them. If anyone is interested, they can do a search for "runner glue" and should come up with the old post.

 

i was the proud 2nd owner of those "runner glue" runners

 

How did the car run when you had them on? Do you remember your 1/4 mile time?

 

i say keep the ones u hav there nice and clean.

 

Those are some good runners you found there alot better then the SLP runners. There TPIS Siamesed Large Tube Runners. I just looked them up in a chart vs the SLPs both installed on a 383TPI. The SLP runners made a max of 401.2 HP@6250RPMs. The TPIS Siamesed Large Tube Runners made 427.7HP@5750 RPMs on the same 383. I believe they stoped making them years ago in favor of the Mini Ram. In the write up they out performed the SLP Cast runners,Lingenfelter Cast Alum., TPIS Large Tube non-siamesed runners aswell as the stock runners.....Good find!

 

Those are not AS&M runners (which TPIS resold IIRC).

 

Are those the set I got off you and resold, or a different set? I remember mine being painted and glossy. ?

Because, its about being clean, not flowing air right?

-- Joe

 

I'll just mediablast them and they will look pretty good after that.

I have a question though.... I have a stock ported TPI base which has been siamesed about 2 inches. If you look at the bottom of the runners, there is a very thin wall dividing the left and right tube. Should I just remove this wall completely? If I do, then there would be no separation all the way from the plenum (the plenum ports are oval, no wall there either) until 2 inches into the base.

Or should I leave them as is?

Not sure if I am making myself clear....

 

anesthes, in the old runner glue thread, you mentioned trying these out and liking them better than your SLPs. Can you elaborate a little?

 

They increased plenum volume and reduced runner length. The ideal setup if you actually want to make power above 4500 RPM (and keep the stock base) The next step up would be a superram, then miniram, and best being a singleplane setup like a victor efi.

-- Joe

 

I'll be getting the motor back together in the next week or two, then I'll give them a try. Until then, the curiousity is killing me.... roughly where did they move your peak to? Is 5000 being optomistic?

 

I don't remember. I only tried them briefly. I think I was shifting around 5500.

-- Joe

 

These are AS&M runners. Though I have the Semi-Siamesed version in the pics.

 

i don't think so.

 

Wow, I wish I could get a set of siamesed stock runners like that for "almost nothing". If anyone has any leads on a modified set like this, please PM me. I am actually going to get a set of spare stock runners, cut them, and run aluminum wire in my Mig to make a set just like yours, if I can't find someone who has a set to sell me. My 327 has 2.02/1.7 valves and is set up for peak power around 6k. I have siamesed my base manifold 2.5" in and hogged out as much metal as I could, and I ported my plenum as well. A siamesed set of runners would mate perfectly to my siamesed base. As it is, I can rev to 6k no problem with the TPI, but my power is probably peaking around 5400-5500. Not bad at all for a TPI, but I'd really like to get my motor breathing as freely to 6k as it did with a carb. Otherwise I may look into the LT1 route (the TPI looks soooo much cooler though underhood)

 

turbo tator has a similar setup, saw him at the track a couple monthes ago, I think he finally broke into the 12's. If I had the fabrication skills to do that I probably would have built a set of those rather than swapping intakes. To bad its so labor intensive or people would be making them left and right.

 

It was by accident that I ran into them. There was an add on the classifieds here on TGO for a TPI setup for which they were asking $225. It was listed as manifold, siamesed runners, afpr, fuel rails, 22 lb injectors, plenum, distributor and tb. Well, it turns out the runners were these, and the throttle body was bored out to 52mm. The seller was local, and I met him at a gas station 3 blocks from my house, and took everything home for $225.

I was mainly interested in the runners, I already have a 52mm tb (I got this one free a couple months ago in a similar way). I'm going to sell the other items, and after I'm done, I basically got free runners and made a profit..

 

92blue do you what do you want to sell those slp runners for?

1987 IROC-Z For sale, 1989 Formula 350 on:

A couple of people have emailed me about them. I think I'm going to hold off on selling them for now until I try the siamesed runners. My pistons are getting here on Monday, and after that my block is getting bored over. It will be another week or two before this thing is running. Maybe three, since I have finals now.

 

here is a good question. how come no company ever cast runners that were just two large tubes? wouldn't it be just as easy as casting the four smaller tubes?

 

How about this one. How come no one with decent TIG or even MIG welding skills hasn't capitalized on this and bought surplus runners and made lots of the AS&M looking runners and sold for a profit. I know I would if I could weld very well.

 

They did, its called AS&M.

Most everyone has figured out TPI is useless and not worth throwing money at. Its just the newer folks on here that actually choose to modify this stuff. (and a few older folks who for whatever reason want to prove something).

For the money spent on a set of runners, one could have a HSR or victor efi.. Sell the TPI setup to some idiot on ebay, and you've got enough money to finish.

-- Joe

 

Personally, I am completely aware of its limitations. I for one would be very satisfied with a mid 13s daily driver with decent fuel mileage. Thats why I decided to go the route that I did. While I am always willing to spend time working on or modifying something myself, I am very reluctant to spend money on anything. Once I sell back the other TPI parts I got, these were basically free. I wouldn't have got them if it were any other way.

If I find that I still want something faster, then perhaps one day I'll give the Stealth Ram a try. I know all my TPI stuff will sell for more than a Stealth costs.

 

the problem with the HSR or carb style manifold efi systems is that there is no egr provision. those of us that live in emissions states can't just say, screw tpi I want power. so we work with what is out there. yes there is the superram but it is hard to work with and assemble so some choose not to do this. now with the new bbk setup we might be able to almost say screw tpi but until it comes out tpi will be the only choice.

 

I would enjoy a test on some of these runners.

 

I would love to get the car tuned in with one set, dyno it, and swap runners. Get the car tuned with the new set, dyno it, and compare results. Unfortunately, I can't justify the expense of dyno time right now, or anywhere in the near future. I used up my christmas present on new pistons... and expenses are already alot more than anticipated to get my car running again. On top of that, I will be getting married next April, so I am trying to save money.

The only shop I know of in south florida with a dyno is South Florida Performance. They charge $80 for 3 pulls. Is anyone here best friends with the owner by any chance????

I wouldn't bet on it. They mainly work on imports.

Uhmmm.... anyone willing to donate money for dyno time??? I wouldn't think so either.

Anyway, I will be posting on this topic whenever I give them a try.
