Re: TPI Long Tube Runner Project

Nice work, I had the same Idea, I did not go as far with it though, and I wanted to keep it looking more stock - https://www.thirdgen.org/forums/tpi/616499-custom-high-flow-runners.html

Re: Custom High Flow Runners

For anyone still interested, I got the engine running, and it runs really strong. I am running an Accel Thruster with a dual sync Distributor, so I still have some tuning to do. But the car pulls...

Re: Custom High Flow Runners

No Idea, I have no access to a flow bench. I don't even know anyone local who has one.
The closest comparison would be the Accel Runners.
The Accel's measure:
Length - 6.625"
Diameter - 1.615"...

Re: Custom High Flow Runners

Alright, here are a few pictures of the completed Runners on the bench and installed. Notice how close the are to the fuel rails, I had to grind the rails a tiny bit to get the clearance.

Re: Custom High Flow Runners

I used the 2x4 guides pictured and a hole saw. I ran the hole saw through the 2x4 guide to keep it centered. The Hole saw was 1.75", which is much larger than the stock tubes, so the tubes just fell...

It will be a while before I get the motor to that point. And it will be impossible to say how much improvement I get from them as I have made several other changes at the same time. New heads, cam,...

Re: Custom High Flow Runners

I don't think it would be worth it for the buyer. So far I am into these for $260:
- spare runners from ebay $25
- new 1.75" tubes $148
- Alumiweld $35
- shipping fro all parts $50

For me to...

Re: Custom High Flow Runners

Oh and one more thing: I am using the Holley AFPR, it has a very low profile wheel to adjust instead of the screw. Check it out if you are having issues, it is part number 512-501.

Re: Custom High Flow Runners

I have not changed the height of the plenum, The shorter length comes from tucking the tubes in tighter to the fuel rails. But no EGR for me, it is going into my 63' Acadian, no emissions control on...

Custom High Flow Runners

OK, I needed some high flow runners, but wanted to maintain the factory look. Some of us like the long tube look. The options are limited, AS&M are usually the choice, the ACCEL's are not bad. But...
