My turbo has a 5.5" inlet.

I'm trying to do an induction of some sort.

I'm guessing you can not buy piping or bends this size?

Could I slice 2 3" pipes, trim, weld together and re round?

Or should I just get some alum sheet rolled that size?

Any ideas or suggestions would be great!

Thank you for your time,
DK

 

Global tech sells 5 and 6". Also, ATP sells them too

There are many options out there man.

 

Get a 5.5-5" transition coupler or stretch a 5" coupler on the turbo and use 5" tube.

 

Find a 5" or 6" filter and just buy tubing to match.
find a metric equivalent tube and stretch a 5in coupler/filter over it.
roll some sheet and pie cut as needed.
make an airbox and use a big flat filter.

welding smaller tubes together would be harder than just getting a 6in tube and taking a slice out of that and squeezing it together a little.

 

a little off topic, but how much of an advantage is it to channel air into the inlet vs. just open compressor inlet, say like on a top mount manifold?

 

bump, on the advantages of running an intake pipe vs. open inlet

 

all I can think of is cleaner air, and less damage to compressor wheel.

 

Thank you, those are some good resources! I figured they would be more expensive.

Thanks for your response

We have got a few mph on the big end doing a 'ram air' into the turbo with no filter. I have heard of others getting 4 mph and very few claiming 6 mph.

I have heard of NA guys seeing positive plenum pressure doing a ram air setup.

Its worth it, but it comes at a cost.
