Engine/Transmission (1998.5 - 2002) Intake base plate DIY

[DCreed]

While I had the Plate off I decided to improve it a little. I've read alot of hype and B. S. called on intake manifolds but haven't heard about this simple mod. anyone can do. It should improve flow to the rear cylinders, and that is a good thing! Has anyone done or tested this before? I would think so ,just couldn't find info. Included a few pics for visual folks like me.

Just thought I'd give an update now that the jury seems to be in with the intake horn testing. I have noticed a 50* temp drop across the board and quicker cool downs with this mod. Bare in mind I have swapped back to stock style occasionally to check data. Please ,someone with flow equipment test this mod. !! Maybe it's just too inexpensive/easy to be real? Try it yourself and see, it can't hurt!

What exactly did you do? It looks like you ground off some of the underside.

The picture is hard to make out but do I see that you radiused the shelf on the head under the opening as well. That is accesible with out deplating and is a real quick improvement to make

I did NO mods to the head at all. Only material removed was on the plate itself. I have a much more aggessive design I'll be trying this spring, but still no head work done.

That looks like a good idea to me.

 

[DCreed]

This is part of the more aggressive one I was talking about. It's only a prototype and a work in progress but the finished one will fit in place of the stock unit ,GREATLY improve flow and be compatible with ALL avail. replacement intakes as well as grid deletes.

 

[DCreed]

here's the pic I couldn't link to last post!#@$%!:-laf

Again, this is a prototype for mock-up and testing it is not pretty. but you have to start somewhere right?

 

[darkhorse]

So do you have some modified air horn to use with that hogged out plate?

 

[DCreed]

The STOCK air horn and heater grid will be used. This plate is only the starting point and a riser will be welded to it on an angle so to allow the use of the stock or aftermarket parts. Stay tuned, the best is yet to come!

This is gonna be interesting!



Not your mothers intake cover? Hummm, not a square hole?, but it has ALWAYS been a square hole Are you actually saying air and square corners are not the best effort from the engine engineers?



This is gonna be interesting!



And we have just had a round of "new" intake horn production from aftermarket manufacturers with all square holes to the intake plenum, and now maybe square is not it?



This is gonna be interesting!

Instead of an angle,are you meaning a tapered adapter? If you add an angle none of the intakes will line up with the cac tube.

[DCreed]

Bob- You are mostly correct and I'm keeping the CAC in near stock position. The "adapter" will be made one piece with the plate. Recessed allen bolts will hold the plate ,while the tear shaped riser will have thread inserts for use of the stock plenum/grid bolts. I should have pics up in a couple days. If all goes well a one piece CNC plate will be made.

To all who were following this: I got it done and it is in testing! So far it feels REALLY GOOD! spool is quicker and cool down is near half the time! I have a dyno run I'm setting up to do a final test but again so far its just great! because of injection line routing this is only for 2nd gen 24v so far... but who knows!



PS, sorry I cant yet post a pic but check the pic at the beginning of this thread and then look at this! gotta be careful!

 

[Joe Mc]

This should be very interesting. My buddies and I always said that opening up that square hole, or even moving it to the center of the intake (duh!), would probably net some real changes.



Look forward to seeing the dyno numbers stock plate and modified.

We were working on this very same concept back in Nov of 2007

We who? did you ever produce one?

 

[KCraft]

i like it. always wanted to design something that would even out the air(like the banks twin ram for the 12v) curious on dyno numbers!!!!

I could care less about the "we", but am interested in the results experienced if it ever came to fruition? Do tell more . . .

Wilson did. I did the dyno testing. I have a few more trucks lined up for more dyno testing. I am trying to find a manual truck in S. Florida but most everybody down here is auto. PM me if you have a manual truck in S. Fla.
