DIY Cold air intake
« on: January 02 2006, 11:25:52 AM »
ok here is my Idea.  in the front of the car right behind the grill i am thinking of putting a 2 1/2 foot piece of PVC pipe.  I am going to block one end off and seal it.  That is going to run into the modified stock air box with a K&N filter and a soild pipe back to the intake.  The thing about the 2 1/2 pice of pipe in the front is i am going to cut out the whole front section of the pipe.  That should give me a "forced" or "ram " air type of effect, Clear as mud or do i need to explain better?
i like burnouts they smell good

Thanks for the info.  What i am meaning is that the whole front area of the pipe would be cut out in other words i will have a large area for the motor to pull the air in.  I figured that the area would be large enough to pull more air at one time.  I am not too concernd about the ram air aspect i just figured this my be a new inexpensive way to keep a stock look and get some performance.

I am up against the same proposition, and after doing a lot of reading on turbobuick 7 turbobuicks I have narrowed mine down to either a mark Hueffman big mouth or a large K & N filter mounted in the engine compartment by the charcolcannist er. If you do a search, you will probably come to the same conclusions. HTH.

I actually consider the Big Mouth setup an upgrade to the large K&N mounted near the charcoal canister.  I noticed an immediate improvement with the Big Mouth setup.

I think some depends on ambient air temperature. I was on a thread last night that was posted somewhee on turbobuicks.co m regarding this very same issue, and there seems to be more than one train of thought. Some of the very experienced racers believe that a cooler air temperature does not help as much as it on a normally aspirated engine due to the turbo, which is where most of the temperature  increase is. BTW, Top Speed, could I e-mail some questions to you regarding your experiences with Champion heads regarding smog requirements?

Listen Methuselah, we're both trying to hustle the same system. Let's use our powers for good.  :prayer:  :psix;

Happy Fucking Monday, Gary.

Hey, works for me. What are your thoughts, natty, and did you read that thread that I highlighted. Very interesting reading from some top minds, too.
Czarnota wants $1700 exchange for heads & intake through his source, so I need to look into Champion. I will call this week and let you know what I find out. But I  know that TopSpeed has some info on them. However, Czarnota's source does not screw with any of the smog, but leaves it all there. Champion likes to remove everything, and i don't know if they will leave everything if asked. Would depend on their manufacturing process and how it's done.

I have a big K&N in the engine compartment by the canister right now.  What i want to do is leave the engine compartment stock appearing but modify the box so that it is a blow through with a K&N filter.  Does this make sense.  Man i wish i had pictures or something i could show you so that this makes since.

Gary, regarding the Champion heads, they make two types -iron 8445 CNC, and aluminum.  I have the iron heads.  The irons can be bought with the egr tower filled with lead or left as cast.  I chose to leave the egr functional since I have to pass  yearly emissions in Atlanta.

Regarding the Big Mouth intake, I feel it is better for a street driven car to take in a lower ambient temp then the under hood temp.   Sure, the turbo adds heat but if you start with a lower temp to begin with then the additive effect will be lower than if you had started with a higher under hood temp.
