dejon powerhouse intake

put on intake today, first of many mods to come. turbo sounds 100% different. damn computer turned my boost down though so it doesn't go over 260hp. next is a tune to cure that problem.

that's sweet dude. Do you notice anything different? I know you're limited to 260 hp but does it pull any harder to 260?

Also what are your intake temps like? I am curious to see if its sucking any heat from the manifold

it feels like it has a little more acceleration, but the big difference is in the sound of the turbo. won't be able to get the full bennifits till i get a tune.

temperature on the display in the car is staying the same and after driving for 45 min. the intake manifold is cold to the touch. i dont have a laser temp checker to see what the temps actually are. its also cold so the real test will be in summer.

X2 and it is also, if you have a SRI like that you MUST have a heat shield like K&N does for their intakes. That intake looks like a piece of tubing laying in the engine bay (doesnt look professional IMO)

Also by the time you buy the tube, filter, air inlet adapter (valve cover vent) etc, you are at $200 + shipping

That is crazy for a little part like that, atleast get a full CAI for about $50-75 more, and you know you have something... And it doesnt look home-made.

could have got the valve cover vent tube welded to the intake but i decided to go with the breather because sucking oil into the turbo is not the best thing in the world for it. why do u need a heat shield when you have a intercooler? if you get a cai, u cool the air that gets heated up by the turbo, that then gets cooled again by the intercooler, makes no sense. cai is good for supercharged not turbo.

^ yep. Clear Image Automotive has done testing on this and a CAI is useless on this car

i've heard it is better to run an oil catch can on the line instead of runing a breather

Very nice call on the SRI vs the CAI on our cars.

I have breathers on my Buick V6 turbo and sometimes you can feel oil in the filters but its because after time the piston rings move and the gaps line up. But I remember I had a oil catch can on my LS1 2004 GTO and that thing filled it up to a 1/4 of oil but to me its going back into the ls1 engine. How much oil is getting suck in anyways??? Close to none?? I'll just keep it the way it came stock.

Now you need charge pipes because with that intake the OEM ones look cheap...really cheap..

disconect it with a 3/8 quick diconect tool and put a breather on it witch came with my intake

where would i get an oil catch can, and where can i see what it looks like? the breather gets real hot and i think it might melt after a while.

i want to get the synapses turbo kit and that comes with the intercooler and piping so i don't want to buy the piping twice, i don't like how it looks either though.

A cai doesn't cool the air it just usually places the filter away from the engine. As for as the SC it has a heat exchanger and cools the air in the manifold via cores.. I wouldn't say it's got for one but not the other...

i find it rather funny when ppl say the SRI are better just because it has a turbo do u not realize the the cooler the air the better. Cold air is more dense for volume so more oxygen!! it will heat up going through the turbo system yet but so u think a SRI wont WRONG it will ever worse. The CAI will draw in denser air with means the oxygen monlcules are closer more compact so the CAI will still benifit more reguardless. With the CAI after it passed the turbo will still be more dense and oxygen rich then with a SRI after the air has passed the turbo.

With that SRI your are going to get major heat soak from the engine. Hotter air is less dense containing less oxygen and oxygen is what ur engine craves to mix with fuel to creat power that is why ppl run Meth or Nitrous cause its a oxygen-rich gas.

My point here is the CAI will still benifit better then the SRI especially in those hot summer days

right, it places the filter away from the engine witch is supposed to suck in cooler air. it is absulutly pointless to put a cai on a turbo car. that what the intercooler is for.

Then how can you say it's good for a SC when they have a W/A intercooler?

Omg dude the air will just be that more dense with the intercooler so we can ram more into the combustion chamber and get more power where with out the intercooler u have to run lower boost levels aswell as the air will be less dense with less oxygen per volume to mix with the fuel!

SOOOOOO if u can get that air denser so u can feed more into the engine and have a more oxygen per volume but u need the air to be cool for that plus it cools the combustion camber temps helping for better detonation!

AND DONT FORGET OUR TURBOS ARE WATER COOLED. they will still be hat as hell but are help major to be cooled to prolong the life of the turbo and help prevent heat soak the incoming air
