I have a spare intake and am getting ready to do some mods to the runners. Would like to see pictures of what guys have used to reduce the plenum size. The links I found were old and the pictures had dissapeared.

THIS IS NOT a REDUCED PLENUM BUT MOD FOR a TURBO DAKOTA.

I would take that last pic and go one step farther and seal the area under it to reduce plenum volume, they really have way too much plenum volume.

Thanks for the pics.

More please especially filling in the plenum.

I'm thinking of making a peice of alluminum that would block off the plenum(one for front half and one for rear half) right at the runner oppenings and then brake a 90 on each one and block it off all the way up to the throttle body opening.

The other idea was to mill a peice that would block the entire bottom at the runner openings. Then make a duct to the bottom of the throttle body. First weld the duct to the bottom throttle body opening. Then cut the plate to fit the duct. Then weld the plate to intake and duct.

Yet another idea build a huge turtle onto the Hughes valley plate that would fill in the plenum and direct airflow.

Why not just get one of the Mopar M1 Magnum manifolds? I've yet to find anyone that has modified a kegger and beat the M1's performance.

Wifes Durango is bone stock and looks like it came off the showroom floor. When I am done it will look the same. Otherwise screw the M1 I would just go with the Edelbrock FI from Hughes.

Problem is Hughes and everyone I have talked to about these engines is after seat of the pants performance. This is the only vehicle I own that I am not looking to make it go faster. Just want some more mileage. The intake is one of the problems with the mileage on these vehicles.

I don't beleive the intake will change the MPG much at all.

What will make a big differance is getting the fuel atomized better. When you pull the intake you will see where the fuel stream shoots right on the PR pinch then onto the floor, well that fuel never gets atomized properly. Put some accell injectors in it, they shoot out a fine spray instead of a straight stream. Another thing that will help is get some quench in it, cheap way is to deck the block about .060 (measure your block don't take my word)and run a .039 head gasket, that should get you about .040 quench and it will bump the compression a little, that should bring the MPG up significantly as well as the low RPM TQ and then you can bump up the gear ratio and really help out the MPG. Another thing is you can get the computer leaned out a little by one of the programmer companys.

Shrinking the plenum will make it more throttle responsive but thats about it. The computer will make adjustments for any A/F ratio changes. The mods I mentioned will make more use of the fuel squirted into the engine so you will make the same power with lower throttle angle and less fuel squirted in, the computer will actually lean out the mix more because the O2 in the exhaust is consumed more completly and it will think it is rich when there is less O2.

Already have a piston designed up and just waiting to get a final bore before ordering.

This may be my first EFI magnum build. But, I know may way around pistons. Just sent over 200 new and used custom pistons to the scrapper. Engine building 101 was done 30 years ago.

NOW BACK TO THE INTAKE MANIFOLD

I need pics of modded beer keg manifolds PLEASE

Intake changes on these engines have proven to increase mileage. Let's see em.

Some pics located here:

A possible easy way to reduce plenum, volume would be to put a 'brick' inside the intake. Obviously you'll want to use a material that can withstand the temperature and not sluff off any material, but otherwise just stick something in there.

You could fill it up with large ballbearings, too, and then fish them out thru the TB with a magnet stick. An easily-adjustable variable plenum -- if you didn't mind the funny noise.

HotRodDave always has good MPG info! Another option would be to get OEM Bosch disc-type injectors (I've heard some bad things about Accell injectors, too, but YMMV).

There were lots of OEM applications in 19 and 24lb sizes and in either the 'big' injector body or the skinny one, just make sure the skinny ones have the EV1 connector.

Ebay will have a BUNCH of listings for reman/cleaned/inspected injectors for about $100/set of 8.

Witchhunter.com has lots of listings and info to read.

The Durango RT has the red colored injectors I'm told they are 23 lb. This is a mod that can be done easily at any time. A few years ago there was an issue with the connectors don't know if this was the injector or not.

I looked in the link to BIONICDODGE but did not see any pictures.
