Hey guys, I have limited space with a SMIC and my single turbo setup so I will be fabbing a 4" pipe to mount my air filter to the turbo. Any tips on angle of piping is appreciated. I wanted to see if anyone had pics. of a similar setup. Also, what's the best place to get a silicon coupling to connect the pipe to the turbo ? Thank you.

If you'd rather email the pics. pleaese send to Onebadd7@cs.com

 

i'm having this done right now, gt-66 with a m2 grande, i think the angle is 30 deg., if genghis kan is coming to tune your car, call him, he's making mine......

 

Badass7: I just had this done. I really had no room for an air filter coming straight out but I got a kit from K&N (Don't know which kit) that is a 90 degree turn 4" thick plastic with a monster filter on it. I'll try to take some pics tommorrow or over the weekend and post them.

 

Here's Mine

I ordered a 45* bend and used about 30* of it. T04s on HKS tubular manifold.

 

The bend angle of the piping between your turbochargers inlet and the air filter doesn't have much (if any) of effect on power production.

Basically just angle it to get your air filter away from warm components and closer to a flowing air source if you can.

 

That would be great. Also, if you can find out what kit it is, I may be able to use the same one. If not, I'll have the pipe made. Thanks to all for the replies.

 

I used a 45 deg silicone coupler, tough to find in 4 inch but they are out there. I recall turbohoses gave me a good discount off the list price.

SOB !! That is expensive for a 4 " silicon coupling.

 

Hey Newbern, where did you get your silicon Coupling from ?

 

ATPturbo.com.. it's just a straight 4" piece..

 

anybody know the air flow loss in a 90* bend?

 

Thank you for the info. NEWB.

 

To get a theoretical number it depends on the diameter, velocity of air and the centerline radius of the 90* bend and to some extent the surface in which you are talking about, whether it is a silicone coupler or polished aluminum.

Basically if you can avoid a bend or at least smooth it out it is in your intrest to do so, but the small amount that it restricts flow is nominal.

 

I think in theory, you lose 1/2 of velocity on every 90 degree bend. I don't remembered if I remembered correctly but I think it is.

 

For a temporary fix, go to your local Lowes or Home Depot. $4 dryer elbow.

Aside from that, a mandrel bender should be able to fabricate your need.

 

Obviously this thread is quite old....

Bumping this because I am fabricating an intake tube as well. My Vmount is being re-angled so I will have more room, but I want to get a good size filter on there. I am also running pre-turbo WI, so having a little more time for water atomization is desirable.

I will be using 4" aluminum pipe to fabricate.

Post them if you got em

 

It really all depends on the turbo charger placement and your IC piping placement.

My previous set up had the compressor low mounted near the shock tower. I was able to use a short 45 degree 4 ply silicone hoes angled slightly upward. This placed the filter towards the passenger head light.

New set up places the compressor higher and farther forward. I had to use a 90 degree aluminum pipe to place the filter directly over the IC.

 

Thanks for the pics. My setup is more like your second revision.

Did you notice any loss with the 90?

I'm looking to hit close to 500whp @ 25psi on my TD61, so I'm worried a 90 will cause a loss in power.

I have a 40, 60, and 90/22 "S" coming. I like the 90/22 "S", as it will angle to the drivers side, then up. We'll see how tight it all is.

 

I honestly do not know if the 90 would cause a loss in power due to so many other things being changed on the car as well. I really do not think there would be any real measurable power difference on a turbo charged car between the 45 and 90.

 

Roger that. I'm going to make it fit, and see how she goes. I picked up two different size filters and a few different elbows. I'll post pics when its together.

I see your power level in your signature and the 90 elbow in your pics. I can see why you feel it won't affect it much.

Thanks for the input

 

On my old set up I pushed my intercooler all the way over and had just enough space for a 9" filter... The hard pipe we made has slits on the edge to allow just enough flexibility for it to very tightly slip on the compressor inlet (no coupler), then a hose clamp tightens the slits and seals the whole the thing down.

 

nice /\

Mine, really wanted to find a way to reduce the length of the transition and smooth it, but this was a fairly clean way around the issue, and i could construct it myself.

 

I was able to just use a strait section of 4" pipe for mine, but my compressor inlet is at more of an angle than most of the other ones I have seen.

 

I see the theme. Most people shift the core over, or have a small enough core to fit the filter on that passenger side. Great looking setups guys!

I unfortunately, don't have that option.

My Rotary Extreme Vmount will arrive soon, and the core stretches most of the way across. With this, I'm looking at options. Much of this is going to depend on the actual intercooler placement angle.

I am injecting 50/50 water meth preturbo. With this what is the real trade-off, and what is it worth? Is the small amount of cooler air from being away from the vmount core worth more bends to restrict flow?

However, these are some options...

35 degree


60 degree


90/22 "S" pipe

 

I'm going to try and sneak mine to the passenger wheel well...somehow.
