turbo tech and hahn will probably come out with one around the same time... i guess just decide by what kind of tubing....... how big it is ......and what filter will be the deciding factor

FiscalFizz

Yeah? Hrmmmm... will def take a look at that.. But I was not aware.

I would prolly still go with the TurboTech Racing ... might not be putting a CAI on... *crossing my fingers it won't void my warranty so I can put one in).

Reason I would go with TurboTech Racing's CAI is Aaron from TTR is ALWAYS on the forums here chatting and responding to questions and what not. And he is really patient with newbs and repeat Questions. I seen Bill from hahns on here a bit..

But TurboTech Racing seems to have great relationships with its customer's and good service as well.

Man I hope the CAI doesn't void warranty. Im almost positive it would though

awesome for a dyi

FiscalFizz

well if you don't have to have it the first few weeks both are out.. You can wait for peeps on here to get both installed and post videos and maybe dyno gains (sure both companies will have dyno tho)

Sound of turbo and Bypass valve I think is also a deciding factor for some people.

If one sounded a lot sweeter then the other , but had a few less H.P. gained, I personally would go with it.

Once again though.... a lot of members said a 45$ K&N drop in noticeably changed the turbo spool and bypass valve sounds. not to mention you get to keep your warranty.

yea its definatly a personal choice. The difference in sound between a drop in K&N and a full tube is probably twice the difference in sound. I had a drop in in it from day 2 of owning it. Now that said the biggest change if your going to use a drop in is to remove the air filter outlet snorkel from under the headlamp. Its not a resonator its just a snorkle. The problem with the snorkle is it necks down to about 2 1/4 inches where it goes into the air box (big restriction) I took that off last week prior to putting on the full cai. As soon as I took that off on the first drive the boost went to about 16.5 pounds and there was in improvement in spool (it did learn back to 15.5 which I expected) but the initial gain in boost told me that the overall airflow had increased. When I put the full tube on the boost went to 18/19 or so (and yes it learned back) but that indicated a large increase in air flow over the K&N without the snorkle.

The difference in spool rate of the turbo I cannot underemphasize. The thing launches like it was shot out of a cannon now which it never did before and it hits 15.5 LBS in 1 second from the time you drop the hammer in first gear. It took about three seconds or to about 4800 RPM stock. The HP/torque total hasn't changed but the torque curve definatly has which should equate to ET regardless of the ECM tuning.

So, do you still have the part numbers you used?

I see

1-MAF adapter tube (modified to work)
1-45* elbow
1- ?? inch long straight pipe (4"? 6"?)
??
??
1- 6" OD x 12" filter.

Can you fill in the blanks? Imitation is the sincerest form of flattery, and that intake looks great for a DIY autozone piece.

great work! I went ahead and removed that tube after we talked last week. (spool time is deff better) I will be back on the dyno with lots more boost on monday I will call ya with the results.

Any idea what the K&N filter drop in part # is?

PimpLay2

its the same as the 2.2 drop in

Smallywood

Thanks I found it on K&N's site: 33-2311

Tomtwtwtw

Kudos, man, that's a nice looking piece of work. May I ask what the total came up to for filter and parts?

Also, were you able to feed the filter from the hood, or did you have to go from under / wheel well?

Gettinausernamesucks

I used these parts.
8208 3in Universal Modular kit
8738 45 elbow
8705 Airflow sensor mount
9732 air filter.

All bought at pep boys or can be had from autozone

The air filter is under the front headlight right where the stock snorkle was.

Went to Milan today for a private session with some vette guys. I ran these numbers as a best.
React. .1448
60FT 2.39
330 ft 6.18
1/8th ET 9.21
1/8th MPH 81.05
1000 ET 11.8053
1000 MPH 94.50
1/4 et 13.9982
1/4 MPH 102.01

Not bad but I just couldn't get the car to launch right like I wanted. The 60 FT sucks. Cutting out the reaction puts it at a 13.84 Not bad for an air intake period. Thats all that it has done to it. And theres another tenth or tenth and a half if I can get it to launch like I want. Theres no reason I can't get it to go 2.20

PS this was the first time I have been at the track actually running in about ten years. I used to own a 9.90 bracket car.

all in all I was quite pleased to break into the 13's

Maxim_X

Reaction time is no added into the time unless you run bracket. Just an FYi.


Was the launch control not working well for you?

Gettinausernamesucks

Got it thanx dude. We were running a sportsman tree so you tell me. I'm a little behind the eight ball here. Like I said its been at least 10 years.

The track was really hooked. If i didn't heat the tires I just couldn't get the car not to spin.( even finessing the clutch) If I heated the tires I just couldn't get it to launch hard without a bog. Great traction though.

Well after looking up the K&N part number a little while ago I went an bought the drop in. I can confirm BOV and Spool are much more noticeable, while as stated above this isn't the dramatic difference you'll get from a CAI- but it is worth the purchase for those who are impatient like me and are waiting for a CAI they don't have to build themselves.

Although I must admit the homebrew looks quite nice! It's good to see someone out there is less patient than I am.

M1kl0

nice, u need a down pipe now +)

i just installed my dp and it whisstles nicely but doesnt blow off ( or recirculates) as good as urs, with a cai on my car with dp, it will sound mean

INDColtsFan18

wow, it looks pretty professional, nice work.

Zander916

Looks great!

For those wanting the drop in filter in the mean time. It's K&N 33-2311.

I went to some local parts stores... Autozone being one of them. They didn't have the current book. Their computers also didn't show anything for an 08 Cobalt SS.
This all before I knew what the part number was. But I looked it up online and it said they should be in stock. I went back and sure enough they had one.

I haven't driven it yet with the drop in... looking forward to it.

I got mine from Amazon.com. It was only $45 and got free super saver shipping...if you are willing to wait for about a week...

Just to let you know, the warranty for the powertrain will be voided if ANYTHING is done to change the out put of the car.

Says it RIGHT in the warranty pamphlet you get when you buy your car.

PimpLay2

13.99 very respectable....

i wont be able to go to the track for a while due to school

but about time I am able to I will be in low 13's on street tires

Reaction has nothing to do with your total time UNLESS you are running brackets.

Better time than me!



I had a slightly higher trap though

TrevMo

I'm assuming you are not talking about the K&N drop in we were just discussing...this does not void any warranty...

PimpLay2

the T/C must love breathing because I killed you on 60ft time..... but you still ran a 13.99 and i ran a 14.18
... the only difference is you have intake and I dont... unless you hit shift points better then I

steddy2112

If it changes the output of the car...they don't have to warranty it.

Simple as that.

They cover bone stock cars, with OEM or OEM equivilent parts.

Technically they can deny warranty coverage for a K&N drop in.

The car was not designed to use a K&N...it was designed to use an AC Delco one.

I mean I highly doubt any dealer would...but keep your stock air filter, just in case...
