Update on my Multi throttle project.

[rs4pro3]

Well I just got almost 80% done with all the machining I needed to do on my adapter plate. For those that Don't remeber I'm working on making a multi throttle intake for the m20 engine using a set of Euro M88 M5 throttles. But to make them fit I had to make an adapter plate so a couple weeks ago I purchased a drill press and have tried to work some everyday driling out the ports. Here are some pics so far of my progress, once i get done drilling i'm taking a file to each por tto remove some metal then smoothing it out with a dremel.





Soemtime soon I'll need to start designing an airbox to feed all 6 throttles that I can hook the stock AFM or a maf onto. I'm hoping maybe to be ablt to fit it onto my stock engine in 2 months or so and drive around and see how it does. I'll keep you guys updated as to how my progress is going.

Looks awesome! Can't wait to see it finished.

Dude, take that to a competant machine shop and have them ream that out properly.

Seriously.

You should try an end mill on your drill press. You will be able to remove a lot more material, make cleaner cuts, and in a lot less time. A good rough end mill will rip through that thick aluminum like butter. I get my machine tools through Enco http://www.use-enco.com/.. They have a lot of sales on over-stock items and have very fast shipping. Once you start using end mills in your drill press, your drill bits will become yesterday's news; just remember to vise the material. If a mill catches, something will give.

Thanks for the tips, with an End mill though won't you have to move the work piece around the milling bit. I just went to northern tool and buaght a $60 drill press 5 speeds 2 inch spindel travel and what not. I'm already basicaly done but I'll look into an end mill. I could talk my M.E. teacher into letting me use the manual milling machine, but I'm not good with corners. Here is a pic of one of the labs I did

I went down to the parts car and put the intake on an took some random shots.




And my favorite shot

[RedBaron86325]

I use end mills on the drill press to simply drill holes, especially when working with aluminum. The mills drill much faster and cleaner than regular drill bits. You just have to watch the heat since you will be usually be using higher speeds on the press than a regular mill.

Good idea, however, the implimentation of an air box/plenum will be fairly tricky to create given the contact between the TB's and the Brake booster.

Thoughts:
Thinner adapter plate
CNC Milling for the adapter plate to cut down on mistakes, and smooth flow


Looks good. :up:

I'd love to CNC machine it but I'm trying to make this for as cheap as possible, Can't go thinner on the adapter plate as there is a coolant pocket in there for coolant coming off the front of the head, the throttles cover where the stock Thermostat mount, So I'm putting a pocket in there then a brass nipple onto which a hose will be attached which will run the coolant into an s14 Coolant pipe into which water from the back of the head, block, heater core will all go. Then I'll have a Single in single out Thermostat welded onto the end of the coolant pipe and run the hoses to the radiator. Also there is the Oil drain off the head which I have to put a pocket in for also. Oh and since I'm getting rid of the stock thermostat housing I'll have to stick a blead screw into the adapter as it will be the highest point of the coolant system.
As for the Airbox. I'm thinking of usuing a rectangular 2x2 plastic box . The front end will be lower than the back end. so the runners coming off the back throttles will bend up to the airbox and the front runners will bend down to the airbox. Then the airbox will have a round opening on the drivers side end onto which a Afm or what ever could be hooked up.
To help with the contact I plan on sticking in a couple washers under the Drivers side Engine mount as right no the throttle linkage is binding due to the back to throttle resting on the booster.

How do you think this will flow? I remember the diagram you made of how the ports from the TB's fit to the head, and some of them looked downright sketchy. Like a very very small portion actually mated.

Also, I really don't know much about intake systems or even engine dynamics for that matter, but something tells me that just a rectangular box feeding 6 TB's doesn't seem like a good idea.

You're a giant douchebag.

Throttle 1 and 6 don't line up that well, but with enough porting and smoothing they'll line up well enough. Basiaclly right now on the adapter plate if it is a large hole striaght threw those are the straight shots then I just have to curve the other machined parts into the stragith threw shots.
Who cares if it looks ugly now, I'm no where near finish. I doubt one could do better with drill bits and a $60 drill press, so far I've spent under $250. I'm not trying to make it scientificaly perfect I'm just trying to make it work, if it dosn't work Oh-well at least i tried.

If we let the critics of the world dictate our plans, we'd all still be walking on hands and feet, banging sticks, and running around naked without fire. :roll:

It has plenty of potential with time and ingenuity anything can be accomplished

That's my point. If I was going to do something like this, I wouldn't go so half ass on it. I'd find someone with a decent machine shop to use. Frankly, I wouldn't use a 60 dollar drill press as a drill press, let alone attempt to rig it up to do milling work.

And you're no longer a member here. I'm sick of your comments towards me, and other members. I certainly don't pay for my bandwidth so you can do this.
