Installed my own custom designed CAI yesterday and did some G-Tech testing today.
Pre CAI 1/4m.stock 14.51 and with custom CAI
1/4m. now at 14.10! Final cost came in a little higher than originally thought at $105 but the outcome is sweet! Soon will be
replacing these stock tires so my handling will improve even above what I have now!
Also eventually headers but would like to
wait till other manufacturers come out with
some. I hate to wait so we'll see...

14.1 and you're stock with just CAI....do you have the timeslip that you can post?

blazerbob1

Well, I live at sea level with very dense air,
close to 100% humidity. I have been a bit
surprised at these times also but I think the
G-Tech is accurate. Have done multiple runs and wahla! Am planning on going sometime this
summer to a sanctioned NRHA event to run
through the lights. My friend has a dragster
and so far this year he is #1 in points. Took
him for a ride in my car and then let him drive. Neeless to say with my mods he was blown away!

Maybe you can start filling in where that Xephyr guy left off. Those are awesome times, congrats!

I guess I'll be the first to ask...got pics??

How I got the idea to design my own custom
CAI was from downloading instructions from www.teamdelsol.com/howto/coldair/diycoldair.htm and then downloaded from xephyrperformance.com/products8.htm for
instruction how to install on our CL-S! Results after a hard run are,by placing your
hand on custom CAI it is actually cool to
touch. Secret is spraying inside and outside
of piping with ceramic paint whereas AEM only
sprays ceramic paint on the outside! CL-S
computer probably hasn't fully recallibrated
the fuel map for the CAI install so maybe will be even faster in 100m!

Sorry guys. I do not have capability of dist-
buting digital pics at this time. I wish to
be able to in the future as my car really
looks sweet with new suspension. Go to the
sights I have shown you and you can build
your own fairly easily that is better at a
fraction of the cost of AEM!

mr tl

read the first line in the 2nd paragraph of the link you posted

Chris

what are you talking about?

blazerbob1

Mr.TL,can you make a point about the paragraph you bring up. Whats your question?!

SidVicious

I think the point is that it says that AEM is the BEST intake on the market - PERIOD yet blazerbob1 claims his is better in his sig. Am I on track here?

BTW, this is not a flame. I encourage custom work.

blazerbob1

Thank you Sid Vicious on encouragement on
building my own CAI. If you all read the
material and my posts you will find that this
CAI runs cooler than an AEM! Isn't this the
reason we are installing these on our cars?!
Bottom line,even without total computer fuel
remap yet I dropped over 4/10 of a second
in 1/4m and almost 6/10 in 0-60!!! 6.6-6.01!!

M5 Lite

Not to TOTALLY take away from the fun, but 14.51 stock and 14.10 with CAI?!?!?!? I have to raise the BS flag here or you need to get yourself another GTech (yours might be messed up). Living at sea level will NOT decrease your 1/4 mile time by 1 full second, it will decrease it by .5 MAX!

Your GTech might still be under warranty, ask them about it.

blazerbob1

Hey! Look at my times again! Are we getting
a little blind!? My 1/4m time improved 4/10
of a second and my 0-60 by 6/10 from 6.60 to
6.01!! I think that is quite reasonable don't
you! Cheers dude!

Rod

Yeah, but I think he meant that the G-Tech times aren't accurate, he was probably expecting something in the lower 15 second, maybe upper 14s, range for your stock runs. I think this has been brought up before, that the G-Tech isn't very accurate, but it is consistent, so this does allow you to see any gains mods may have given you, even though the 1/4 mile and 0-60 times aren't precisely accurate.

blazerbob1

Well a stock CL-S easily runs 6.6 0-60 so
G-Tech certainly nails that one right on! The fact that I live in a very cool sea level
town is a factor here. As previously posted
I will be racing in a NHRA event later in
summer so will have official times.

scalbert

When were the before and after runs made?? What were the exact conditions for each?? Has a completely different vehicle (any type) been run at this same location with this same GTech??

I'm not disputing what you observed; I will dispute the absolute accuracy. A statement was made that the runs were at sea level and in dense air, 100% humidity. Higher humidity is worse for a cars performance, there is a displacement effect lowering the concentration of O2. Being at sea level could certainly help achieve better numbers but by the amount stated you much have one ringer there... I would go to a track and run it against the timing lights, which would be a great way to verify the accuracy.

A CAI, regardless of make, for the CL-S would not give you the 30 - 40 HP required to drop the times the way you have observed. So there seems to be something else here that would contribute to the delta. It could be a variety of things, different

Secondly, a CAI is only more effective in slow or stopped traffic. Yes, coating it will help slow heat soak. But the filter element may still be exposed to some heat so ingestion is part of the worry. When cruising for extended periods the under hood temperature will be about 10 - 15 degrees higher than ambient negating the total CAI effect. Stop and the intake temps will increase at a rate of about 4 times as quick as with an open under hood element. Another way to think about it is that at cruise we are probably moving about 100 CFM through the engine, that is 1.6 cubic feet per second. How long do you think it takes for an intake to move all of the air in the engine bay?? And it has to be replaced from somewhere, outside the engine bay…

In this case when comparing the AEM CAI, both are utilizing a CAI induction method so the difference lies between internal coatings. This will slow heat soak when in traffic or stopped but by how much?? I know it is not going to be by 75 - 100 degrees in a matter of minutes.

You are right to the point, scalbert.
Once I saw a study that compares air temprature between CAI and stock air box.

At crusing speed the difference in temprature was mimimal (less than 10dF).

However, at low speed there was a noticable difference.

Another issue is that how free flow the stock air box is compared to an open element filter? If the difference is big, a CAI would help a lot.

So, I guess the CAI would much help in drag racing if at all.

Dynos could be scewed wether the hood is closed, a huge fan is running... or non at all. So, I guess that the duno opertators would do their best to make their customer happy and to justify spending a $100 on a dyno plot.

I disagree. CAI do help out in drag racing. On my integ, I lost a good amount of time by just adding the aem. I have dyno slips to prove it.

Folks,

I think a point has to be made that AEM is nothing but an overpriced marketing gimmick...at the end of the day, we are looking at a tube and a K&N filter here, no if, ands or buts about it. I strongly believe that these guys need some competition in order to drop their prices and increase their levels of customer service (ie: GoldTypeS's ordeal).

I would strongly encourage people to come up with their own design, while I dislike the attitude of some folks here who start arguing and contesting track times and HP increses. Guess what? every one of us is gonna see different results when bolting on a mod....it is simply buyer beware!
