Well I said once that I would not be doing anymore to my car... then those damn CAI's HAD to go on sale lol. Anyway, I went ahead and got the AGP one and it should be in shortly. I also have a front 02 sensor, new plugs and everything is ready to go together and will obviously need to be retuned.

My question is... I cannot afford to get a new turbo, but later on it will be much easier for me to have the intake and stock turbo ported and polished... with these along with the new CAI (running a drop in now) could I get to that 400 whp mark?

 

oh, I forgot to post that my mods are a 4" ETS IC, UICP, the drop in of course, 3 port, Perrin BOV. I was tuned at 330 or 335 whp on an MBC. AMS claims a 50 hp gain on their true CAI which is basically what I am getting, obviously I won't get that kind of power since i'm already using a good drop in (green performance), but maybe 20 more whp would be possible?

 

Honestly, probably nothing. The stock turbo doesn't need more than a drop-in and a tune. It'll add intake and BOV noise, though, if you like that.

400 is difficult to crack on the stock turbo on a normal reading dyno. E85 or meth&cams will get you close. If you don't have a downpipe-back exhaust then that's what is holding you back from the 360's right now.

Porting isn't worthwhile until you have a larger turbo (even then it is questionable).

 

I don't know, AMS claimed 50 whp gain with one without a tune and no supporting mods... it must put put out at least a little getting rid of that ribbed condom of an intake that's on it now.

 

to my knowledge, nobody has touched the 400 mark on stock turbo, even on E85 with every bolton under the sun.

so to answer your question: no, ain't gonna happen, not a chance, with just a CAI and a flash. (not sure what your other mods are--if any--but if an intake isn't yet crossed off your list, I'm guessing you're not very far along).

 

I had posted my mods like 2 or 3 posts up man lol.

I'm asking because yeah, most people get them for sound, but a good drop in will do just as well. Most have a CAI because it makes noise which I could care less about and their CAI's are just intakes, not the ones that go down into the fender and have a higher volume of cold air without the heatsoak from that roasting engine bay... you can put as many boxes and and shields on it, but heat is heat and IMO will get to the intake no matter what.... but then again I don't know, i'm not expert on this. As I had posted, I bought the one similar to what AMS uses (just didn't get ripped off on their priices) and they make 50 hp, while ETS has posted numbers at around 22 or 27? Something in or around that area.

 

actually its been done, check out dcevoclub.com

 

I'm not trying to go to great lengths and spend more money than if I were to just get another turbo down the line, but I know based on what others have as far as whp and their times that my car would be a 12.8 or lower car... i'm ok with that, I don't even track it anyway... I just like to know the car is fast if I ever happen to get to a road course... to bad there aren't any near me

 

An intake on an untuned car makes power because it fools the ECU into leaning out the AFR. A cold air intake will not make more power, it will just add conistency. But, when you car is tuned I doubt you will gain even 5 whp over your tuned car. YMMV and please post the results if you do go this route, I have never seen before / after results with CAI on tuned cars.

 

I realize that it does this... but any little bit of reducing air temperature going into a hot turbo would have to give it a decent amount of help.

 

Would I spend less just getting the bigger turbo, fuel pump and injectors to get to that mark?

 

If you have E85 then that's the best bang/buck. If you buy a Green then you could get by with the stock fuel pump on pump gas.

Are you stock exhaust? First thing you should do is dump the cat and CBE. A test pipe is like $80 and good for 15whp on its own (once tuned for).

 

best I could find over there was a link to this video, which despite being a year old, claims to hold the 93oct+pump record: http://www.youtube.com/watch?v=cWM5upe8MfE

at any rate, it is certainly the exception and not the rule... and I'm still not convinced it has ever happened outside of a dyno set to "feel-good-mode" somewhere in Florida

 

DG had a history of faking numbers. I wouldn't trust that video.

Also something to keep in mind is you can tune a car to some ridiculous number on a dyno video, doesn't mean it's built to last.

400whp on a stock turbo isn't obtainable imo. Not on a normal reading dyno.

Back to the CAI results, you gotta remember the whole reason for the design in our cars (front mount intercooler, turbo in the back, intake in the front is cooling). You may see +/- 1 to 5whp but it isn't going to be because of the CAI, it's going to be because of the environment, air density in the air, etc.

If you have an intake or drop-in already, I'd save your money and put it towards something else.

 

I agree with all this,

400 is unlikely.

If you want e85, a clutch will be down the line as well, just ask yourself how much your wiling to spend to get to 400. If you cant afford a turbo now, id wait to put anything on that will really add serious power. Don't want something to get f-ed and need to come up with quick bucks.
