The eurorace header just showed up, YES! Options

Hey guys, this is something of a continuation thread of these last two threads.

The eurorace header showed up today! YES!!!

Here is a pic of it sitting in the garage somewhat assembled.

Now I have a couple questions:

1: Do I use only new copper gaskets?

2: Is there a specific procedure to preparing the gaskets prior to install?

3: Should I use those copper nuts or just double nut the stub pipes to the exhaust ports?

4: Should I do a little dance after putting it all on without any pulled studs?

I'll post a pic of the dual motorcycle exhaust once I launch my other computer.

If Jake signs in....how much will this help my engine over that dual motorcycle exhaust?

I don't think you have to wait for Jake to tell you that the dual motorcycle exhaust on a TYPE IV simply sucks... I will tell you they suck..!!!!! (IMG:style_emoticons/default/agree.gif) (IMG:style_emoticons/default/biggrin.gif)

I would ONLY use NEW copper crush rings if I were you. In that way. You start with a known GOOD set of copper rings/gaskets.

Jake sells the good ones. They are made of some copper alloy that works better than the stock items according to a long conversation I had with Len Hoffman on that exact subject. I respect Lens advice in a big way.

I would also throw a file on all 12 flange surfaces to make sure they are flat. High and marks will show up instantly with judicious use of a flat file. Make em flat if they aren't already.

I just did Aarons that way. I found 3 of the flanges were a wee bit NOT FLAT. I simply filed em flat. Easy Peasy........

Do this BEFORE you mock up the exhaust.

Also make sure your primary pipes / collector slip into each other without to much force. You might have to sand a bit of the grime away to make them a easy slip fit. Cause thats a bitch to do under the car. Check it now.

You can double nut or use the copper PLATED nuts. Your choice.

Check to see if the stub pipes have numbers on them. If so. That MAY mean they are made to fin a particular header pipe. Some have em. Some don't. Check before installation..!!!!

NOTE: If you have a hard time getting the copper rings to stay put when installing your stubs.
Ya might wanna use some thick style super Glue to hold em in, whilst installing the stubs. Thats the way I do it anyway. As well as many others.



Once you have your stubs bolted up. Start bolting the primary pipes to each appropriate stub pipe. BUT LEAVE THE NUTS AND BOLTS LOOSE. As you will need some maneuvering room to get all 4 pipes into the collector. Wiggle room is important at this juncture.

Once it's all mocked up and fits correctly. THEN tighten the primary pipes to the stub pipes and then the collector.

Hope that helps.

And then do a dance in effigy to the EuroRace..

Cheers,
Clayton

My hat's off to you Clayton for your exemplary explanation!

Thanks!

p.s. I knew they were copper plated nuts, i just wanted you guys to know exactly what I'm talking about.

This is a pic of the original exhaust viewed from the back of the car.

The mufflers are from a suzuki.

One goes to one bank, the other goes to the other bank.

How do I dispose of these things? Can they be recycled?

[Demick]

How are you going to double nut the stub pipes to the heads? The only way a double nut provides any locking power is to tighten the nuts against one another. That means getting a wrench on both at the same time. Not sure how you would accomplish that. Simply installing one nut and then installing a 2nd one under it does very little to lock them together.

Do it right and use nuts with a built-in locking feature - like the copper plated nuts have.

[Joe Ricard]

Word

Copper nuts are good.

Motor Cycle mufflers are meant for Motorcycles.

Have we steered you wrong so far?

[Chris Pincetich]

Twystd1 got most of it - I still gotta say RIGHT ON for hookin me up with my Eurorace last year (IMG:style_emoticons/default/beerchug.gif)

You got it mocked up on the floor - perfect. Take it slow and loose on the install to ensure everything fits. For the stub pipe connections buy some copper RTV and several lengths of bolts. A thin layer of the copper high temp silicone = no leaks on those flat surface interfaces. There are a couple places where the bend of the pipe is too tight to fit long bolts, so you need a short bolt for the tight spot. I also dipped my bolts in milk of magnesia as an anti-seize as recommended by Jake and others.

Make sure you anneal the new copper gaskets. (IMG:style_emoticons/default/smile.gif)


What are you planning to do with the bike mufflers? If they are going into the trash could you send me a PM.

[purple]

I ordered the copper nuts from pelican, the copper rings from Jake this morning.

The bike mufflers have been PMed off me by Rand already, but if he doesnt like the pics I'm sending I'll put you next on the list.

Question, what does annealing mean? Do I need a blowtorch for that?

http://en.wikipedia.org/wiki/Annealing_%28metallurgy%29

is that what I need to do? Heat it until glowing and then let it cool slowly?

I'd need a MAP torch to do that dont I?

Why milk of magnesia?

Thanks guys!

[purple]

Demick, did you get that phrase in your sig from Phil Hendrie?

[Demick]

No idea who Phil Hendrie is. I got it from Adam Savage (Mythbusters)

[purple]

oh yeah, that's where I heard that.

Phil Hendrie is a comic genius, he satirizes talk radio

enjoy some clips, they're funny!

[jd74914]

If you drop the copper gaskets on the ground they will make a pinging sound. What you want to do is heat them until they slightly change color and so that they don't make that sharp sound when dropped. This means that the molecules have been rearranged and the metal is effectively "softer" or more mailable so they seal better.

[jasons]

I don't know if anyone has given you this advice yet but..... You will need to get a heat shield sleeve to wrap your clutch and speedo cable. Otherwise, they will drag on the exhaust and smell like burnt rubber.

Here is one example....

Heat sleeve

[Twystd1]

Good call jasons... I forgot about that...

AND I would ask Jake FIRST before you anneal the Jakes crush rings.

I put em in right out of the bag... 2 sets on 2 different engines.NO LEAKS. End of story.

That was as per Len Hoffman.

Clayton

[Aaron Cox]

back to the heat sleeving....

i still managed to melt cables with that, use a bailing wire solution AND heat sleeve to keep it off the header.

[purple]

Good call on the sleeving guys. I was wondering if I'd have to re-kagigger the clutch linkage angle or something on accounta this header.

Well, Jake hasn't stepped in yet, so I dunno if I have to anneal his rings. I think I'll put them on and see what happens (IMG:style_emoticons/default/smile.gif)

[Jake Raby]

No annealing necessary, just install and retighten them after a few minutes of run time.

The Type 4 is all about exhaust- period. Dual mufflers and crazy half assed hodge podge backyard excuses are what make for untunable engines and catastrophic failures.

Every time I see a TIV without a collector, running dual mufflers with an owner that believes "it's OK" it makes me want to go ballistic!

[purple]

Thanks Jake,

every time you read one of my threads it's as if someone sh!t in your cereal, BONG! (IMG:style_emoticons/default/stromberg.gif)

Hopefully I'll have a thread you'll be happy about some day (IMG:style_emoticons/default/smile.gif)

If you're ever in Houston, go down Richmond avenue near the Galleria, there is a speed shop there. Vent your spleen there (IMG:style_emoticons/default/wink.gif)

[Chris Pincetich]

Oh yeah - tha cables.
I bought the cable heat shield and no worries so far. Clutch cable came off and slipped inside OK, speedo cable I tore open the sleeve and stapled it back together. Worked great. The 2 cables are now bundled and tied up away from the header against the engine mount, engine tin mount tab on case, and clutch pulley bracket hole. I also used fiber insulating heat wrap onthe header and collector so both the header and cables are wrapped. Heat kills! (IMG:style_emoticons/default/beerchug.gif)
