Got butterfly valves?

quicksilvr · Post by **quicksilvr** » Sat Sep 24, 2005 6:18 pm

I would be the happiest person in the world if someone could get me the specifications for the butterfly valves in a magnum intake manifold. I need the diameter and the thickness, and I need to know if they have any beveled or chamfered edges. And anything else that you might know that would enable my brother to fabricate them from sheet aluminum. He will probably not have the exact thickness of aluminum sheet, so it will have to be lathed, and in order to chuck it in the lathe, he'll need to screw it onto something. Meaning, if I could also get the location of the holes that attach the valves to the spindle, that would be awesome. Then he can use those holes to attach a stud that will let him hold on to it to lathe them down.

DAMN i just put mine back together last night and had the digital calipers out, too! If no answere by tomorow, i can pull one out for ya and let you know

Just an FYI, they are not perfectly round... a bit longer on one end than the other.

bump, it's tomorrow.....numbers anyone??

I don't want anyone to have to take their mani apart, but dang, I don't know how else to fix my problem.

If I knew when I was getting my ported intake mani back I'll help you but I have no idea when that'll be haha.

Yours is off in Arizonza at NRGY isnt it? I would LOVE to send them my magnum head and manifold and have them do their magic before I ever even put it all on my car....but unless I get a huge raise, that's not happening anytime soon. Do they work any kind of deals if you have them work on more than one item? Don't get me wrong, their prices are great for the quality they put out, but I was just wondering.

Yup... he's been way to busy lately with some other stuff going on and last I heard Nick haulted incoming orders for a bit to catch up and get everything organized.

Also doubt he'd do a discount for that since it's really only Nick doing the work.

Ahh. He's been around long enough to know how to handle it though I would think. Dangit!, thinking about this made me go to the site and now I really want to send him my head and manifold for a street power port and a manifold port. But, then if I'm going to do it, I might as well pay for the race port....

Damn, keep forgetting to get these measurements! AHHH ill write it on my hand. Its the only memory i have

Mines already on my car, otherwise I would measure them up for you.

As long as you give him the lower section of the plenum he can measure them up for you. The only thing is I can't remember if they're elliptical or circular. I think circular, but don't hold me to it. Taking a guess from memory, I would estimate the thickness to be around 12-14ga material.

I did grab a pic though, don't know if it helps you any.

Hey, thanks for the consideration guys, I am actually now a very happy camper. I guy in Cincinnati has the complete butterfly assembly with actuator rod that I'm getting from him. Ending up working way better than fabricating them.

Yes, that was one way to do it. Problem is, he is in Longview, Texas, and the lower plenum is in St. Joseph, Missouri. I was trying to avoid shipping it down there and back. Also, just measuring the plenum isn't the best way to do it, because there is a small amount of clearance needed, and only by measuring the actual valves would I know exactly what that clearance needed to be.

Hmmm... who in Cincy?

I yanked my butterflies out yesterday if you need them PM me.

nodestiny · Post by **nodestiny** » Sun Oct 02, 2005 1:14 pm

HEY I measured it with my digital capliper. I drew it down on carboard (traced it) and measured it up. Ill scan it and shoot it on the boards as soon as i get scanner access!

His screen name is Under Pressure, we got in touch over at neonspeed.com. His email is jtrumpfl05. I don't know his name specifically.

Thanks a ton man, I appreciate it alot. I haven't finalized this deal with the guy in Cinci, so pictures and specs would be greatly appreciated in case it doesn't pan out for whatever reason.

you should have the flies either monday or tuesday....C-yA

Dad said they showed up a couple days ago. I'll hopefully get the manifold put all back together next weekend with the 'flies in. Thanks a bunch man!

no problem....

not to bring an old post back up but i need this as well, picked up an r/t that the kid took the butterfly's out and I need a set or need a set made/buy a new manifold any help would be awesome thanks in advance

Thinking about it, they wouldn't be too critical to make. They don't actually need to seal perfectly, as there are 4 open runners next to them. They just need to block the airflow until needed. some small gaps around the edges prolly won't affect much at all. the air is going to go through the "normal" runners before it tries to get by the plates. Not like there is a huge pressure drop behind them.

^ Exactly what I was thinking when I made mine. I used some thin aluminum I had laying around, and cut them to shape and then filled them down. The bolts olding them in are uber small. I wanna say m3.

Post by **occasional demons** » Thu Apr 23, 2009 9:27 am

I knew someone had done it!

M3 sounds right, that's what the Mustang TB plate screws are.

Edit: Lowes has the screws.

just got home from picking myself up $2.50 worth of 12 gauge aluminum, and also a nice lil project for sometime this weekend or early next week.

Post by **occasional demons** » Fri Apr 24, 2009 12:29 pm

The screws might be M4, looking at some here at work, M3 seems too small M5 way too big.

Fuck, now I feel like Goldilocks.

hehe. Yeah I don't remember either, its been a while since I did it. They're either m3 or m4 for sure.

no worries I was just going to bring the lower half in and figure it out the old fashion way...try it till it fits lol

Post by **occasional demons** » Fri Apr 24, 2009 9:26 pm

It's what I do if I don't know for sure. I get a kick out of the looks I get.

thats the best part, and sometimes you get the parts your looking for to
