Also, if the runner area is larger than the intake port, there will be turbulence at the transition from the intake to the port. Not a good idea.

 

Tuning it would probably be a nightmare as well. Fuel could easily cross from one cylinder to another when the intake valves close.

 

yea seems like the fuel would get trown around alot in the intake and each injector pulse owuldnt completely go to the cylender it is expectig it to go into

TPI set ups usually siamese the runners BEFORE the injector to increase the air flow until necessary (where the injectors are + a lil).

 

Really Really Bad Idea!

 

Something to bear in mind about the TPI setups having their runners siamesed is that they don't do it all the way to the head port. They usually only siamese the runner tubes and/or up to a short length of the ports in the base manifold. The idea behind it is to bring balance to the huge deficit of plenum volume to runner length. (The siamesed runners acting like an extension of the plenum.)

This is really just a bandaid mod to make up for the lack of high rpm breathability in the TPI intakes, which is not a problem with the LT1 version. It's an apples and oranges comparison.

 

Let's see, with firing order 1-8-4-3-6-5-7-2, 5 and 7 are in sequence and would be a pair of siamesed runners. No cylinder fires at the same time as another.

 

yea what you said. Reason i used that as a comparison is sometimes people get information from mixed sources. In any case, you said what i ment to say much better hah

 

Could the runners be shortened with the intention of gaining plenum volume? It would be interesting to see what the optimum runner length would be to promote useable standing waves. Might be a good thing?

 

optimal runner length is about double what they are now!

 

Do we move from the weak 5th harmonic to the almost non-existant 7th or 8th for intake ramming in this case? Ron Sperry and Gordon Blair would choke.
