intake tube on turbo

I added this pipe off of the intake side of the turbo where the fins are. I used to have some screen cut and clamped over it. but it was getting air from around the radiator. with this new setup can i expect some extra ponies? since its pulling air from a cooler area? anyone have first hand experience or advise on this? thanks

prob one?haha dunno
its just much safer than running a mesh only on turbo

huh? anyway i read that someone put one on the turbo to see if it made a difference and they gained 16HP on the dyno. seems a little high but does the spinning of the fins generate some kind of suction? if it does then i understand how colder air would possably work. but still looking for some help guys

All I’ve got to say is wow… :shock:

No you won’t get extra power…

colder is better. why wouldnt it? so its not gonna make a difference sucking in cooler air as opposed to 200 Degree’s from the radiator and downpipe? that dont make sense. why do the kits come with this option if it didnt have a purpose?

they do serve a purpose. keep clean air going into the system. just like a N/A setup

so im not getting any extra horsepower? i read an artical with a dyno chart showing an increase. i guess you guys think otherwise. ill post the artical. it felt stronger when i drove it. I know thats not a true testament of proof because the proof is in the dyno sheet. but anyone else think is an actual hp provider? thanks guys :corn:

No more spooling sounds. :gay:

Haha, clean though. :up:

well i took the filter off today and the pipe sucks about as hard as the TB does, so pulling air from a colder source is definatly gonna bring me some hp. i was hoping someone would agree but i guess not. it really makes no sense for it not to. it was pulling air in by my radiator which was very hot, i also noticed my car overheated a little bit. now its pulling in air from where the battery was before i relocated it. virtually no heat in that area. I guess im on my oun with thinking coolder air = more hp

bump

I would think that the filter off the inlet would increase spool time. No filter means no restriction on spooiling the turbo so technically it is better. but a filter would prevent dirt from getting into ur turbo.

you wont notice a difference other than sound

i dont think it will make much difference either if its going through an intercooler

exactly! the intercooler is made for cooling down the boost, not a filter. i had one of those intake tubes on mine, and i took it off. not only does it sound cooler, but the turbo spools faster.

what do u guys do about the pcv system without the intake piping?

When the hood is down and the engine is running the engine bay becomes like an oven. It doesn’t matter if the air intake is directly behind the radiator or where it is in this picture it will still be sucking in hot air as the temperature equalizes throughout the engine bay. The only way you would see power gains from moving the intake is if you were able to isolate it from the heat of the engine bay and provide it with a cool air source.

The reason why you use an air intake with filter is the same reason you use one on a NA car. In my opinion it’s even more important to have one on a turbo car since the compressor is literally sucking up a great volume of air and that always includes dirt, rocks, small animals, and the neighbor’s kids.

If you don’t use an air filter don’t come on here bitching about how your compressor wheel exploded after coming in contact with a pebble…

I would have agreed with you and said you probably will see some small gains, as every degree your intake temp drops, it results in x amount of hp. This is the whole idea behind intercoolers. However, I think ^he^ has a good point, with the hood closed it probably does act like an oven. But then again, when you are moving, the air is supposed to be flowing through the engine bay and if the filter is not directly behind the radiator picking up the heat that the radiator just removed from the coolant, then yes, again I do think you will benefit from having the pipe.

I also kinda think it would improve flow to the turbo. Just because of this…have you ever felt how slow your car is if you run open throttle body(NA of course)? It’s because with an intake, the air forms into a nice uniform cylindrical column to flow through the throttle body better. Without an intake tube, it flows in with a lot more turbulence. This is why people dont just put a filter on a throttle body. But, the turbo causes a shitload of turbulence anyways, so maybe it doesnt make a difference in that case?

Either way, I think it will drop the temp of the air before the turbo, which will allow it to be cooled even further at the intercooler, which should net you some small gains. But what do I know, I’m just a kid.

point taken. thank you

When you are moving, the temperature under the hood is ambient to the temperature otuside the car. Regardless of heat comnig from the engine. So you are definantly getting cooler air. The cooler air gonig in, the cooler air coming out of the turbo, the less the intercooler has to soak in.

Also if you look at how air enters a TB, or a turbo, having any kind of pipe on it atleast the same diameter will net SOME gains. Air needs time to channel in and flow smoothly. With running just off the turbo, air is comnig in from everywhere and turbulence is created. With an intake arm, it channels it in, then pulls it in straight. It’s all been proven to help slightly, but nothing crazy. Having an intake arm is like a velocity stack on individual throttle bodies… Helps channel air in better.
