Made a ramhorn - now afraid of metal pieces inside
 

A friend of mine made me an equal length ramhorn manifold. It's welded with mig (only co2).

The problem is that some of the welds went trough, so there might be some metal pieces inside the manifold that could damage my turbo and maybe also my engine? :-\ :-\

What should I do now? - I can't just get inside and polish all metal pieces and welds >:(
maybe should I run the engine with this manifold without turbo, so it cleans itself when it reaches operating temperature?

I really don't know what to do :-[

blow it out with an air hose then put it on

Re: Made a ramhorn - now afraid of metal pieces inside
 

+1 unless you large chunks of metal that is blocking exhaust flow then do not worry about it.

btw nice looking mani. ;D

Re: Made a ramhorn - now afraid of metal pieces inside
 

decent mani, should have used a tig tho.

Re: Made a ramhorn - now afraid of metal pieces inside
 

why?

Re: Made a ramhorn - now afraid of metal pieces inside
 

Thx for the compliments ;) I'm just worried that there are some metal pieces left inside the manifold that could come off while operating at high temperature=> destroying my turbo :-\ Should I clean the inside somehow?

Re: Made a ramhorn - now afraid of metal pieces inside
 

I'm not sure how that's gonna hold up. It looks to me like what's been welded so far is just using a series of tacks and what give much strength at all.

your friend needs to learn how to weld beads and not make 5,000 tack welds.

i ---- around sometimes to make fun of ssauto and make welds like that on non-supporting things.

my fluxcore > your friend

Re: Made a ramhorn - now afraid of metal pieces inside
 

cleaner

Re: Made a ramhorn - now afraid of metal pieces inside
 

I often worry the same....

So I take a wooden mallet and beat the ---- out of the manifold. Stuff DOES fall out.

TOILET SNAKE

Re: Made a ramhorn - now afraid of metal pieces inside
 

this actually does work. i do it sometimes to get little beads that fell in and got stuck out.

Re: Made a ramhorn - now afraid of metal pieces inside
 

Sand blast it out.

Re: Made a ramhorn - now afraid of metal pieces inside
 

nice mani

Re: Made a ramhorn - now afraid of metal pieces inside
 

take it to a car wash and blast it

Re: Made a ramhorn - now afraid of metal pieces inside
 

You can get a flexable adapter for a die grinder and feed it through the runners, sort of like a tiolet snake. A 60 grit flat wheel and go to town.

Re: Made a ramhorn - now afraid of metal pieces inside
 

This would be my idea!

The mani is now welded and corrected with tig welder, just to be safe + is getting the wastegate port welded and flanges are being resurfaced. Pics coming soon.
Then I will clean the inside and it should be done :6

Re: Made a ramhorn - now afraid of metal pieces inside
 

Should have removed the excess as you went along welding the pieces together. Now, I think the snake and mallet ideas would be your best option. If it's still there after that, I doubt it will come loose.

Re: Made a ramhorn - now afraid of metal pieces inside
 

i know it aint cheap but you could take it to a place that does extrude honing

Re: Made a ramhorn - now afraid of metal pieces inside
 

hose the ------- thing down you -----. I notched my block in car with the crank still in it. Brass balls baby

Re: Made a ramhorn - now afraid of metal pieces inside
 

Get a jank-ass CDM turbo, boost that ---- to 1bar with a few heat cycles, then you'll be good with the real turbo. Or find a place that does ghetto extrude-honing for cheap.

FYI tack welding for the entire bead on a MIG is complete fail. If you beat is with so much as a wet paper bag it might crack. The basemetal doesn't get hot enough, and you have less penetration than an asian dick in a black -----. If your friend wants that psudo-TIG look, tell him to hold the trigger steady, but just move the stinger in spurts. Still not as good as a normal weld, but FAR better than a million tacks.

I wonder if you could run a brass bottle brush through it with a drill.

solution
 

I read here http://autospeed.com/cms/A_2604/arti...popularArticle
that caustic soda (NaOH) can be used to clean inside the manifold!? Anyone ever tried this?

dont use a brass brush use stainless.
1) brass will be eaten alive by the pipe
2) it wont last long
3) all that brass being worn is deposited on the steel
What happens is you waste alot of money for ensuring that if you ever get that spot hot enough to weld you'll have inclusions in the weld

It would have been stronger to braze it together with bronze filler rods.



i wouldn't invite any more corrosion into a manifold that it will see in service.

Good point. I was thinking more about using the bottle brush than the material used.

idk but it look badass!

You could always try a pressure washer to clean it out.

pixs of it installed????

nice work, wish i could make one...

installed:-D
 

Installed with my plastic welded rad: (mani is sand blasted&painted)

Car pulls like hell with a T3/T4 turbo, 3" exhaust...

Nice, no damaged turbo, yet?

nope. Still pulling like a champ :-D

i was in the same boat as you and i used the flex shaft on a dremel with a grinding wheel and most all of it came out in seconds but there is still stuff i cant get to so ---- it.

looks real good i hope it holds up. try not to run a real lean setup, keep temps down

i like it cuz it looks cheap to make

blow it out with a compressor?

nice

get a bottle cleaner and shove it thru

where did you ge the pipe to make the mani?
