• Air intake refresher course. by fdnyguy on 17 Apr, 2012 18:46
• I oddly recall a thread (upgrade a 1.6 N/A, maybe??) where pics of different air intakes were shown with what some of you did to get more air in. Obviously, the stock intake with a Giles IP is contradictory, so if anyone has pics or ideas to help, I would appreciate it. And may need the 1.6 filter assembly to modify, if anyone has one.
  
  
  Thanks. Stay safe, stay well. Jimmy.

  FAQ Make your 1.6 n/a a faster car IIRC.
  

  
  Thank you, Sir......
  
  I've put 4k on the rebuilt, just did a 1500 mile r/t from NYC to Toronto/Montreal and back, and while the Giles IP has held up on hills, I had to downshift about 6x going up hills. I am not complaining, for the car has run great on other hills, I tend to think I-87 in upper NY state has higher grades than I-81 in lower NY State. So I really do think the pump is working its magic. But my best mileage has only been about 40-41, so I am wondering if more air would improve that (obviously), or I may need a few more thousand miles under it's belt to really break in. Where/who else but to ask but you guys, right?
  
  As for the car, the rebuilt 1.6, Giles IP, 1,8 gasser exhaust manifold and d/p from techtronics, and a 2.25" exhaust, running 195/60R14 on the Mk3 'flyer' wheels.
  
  Again, many thanks. I like the PVC pipe setup a little more, but nice jobs by all.
  
  Stay safe, stay well. Jimmy.

• I have a stock plastic air filter cover, four clips, and I do have an intake but as weird as this sounds, it looks like the clips wore through the intake, I could mig weld it up tho, Im not sure if Im going to run N/A, turbo, or custom ram... but doubt I will run the stock intake

  the stock clips DO WEAR INTO THE MANIFOLD..
  
  and the stock intake is really not as restrictive as everyone thinks..
  
  its the air box/intake snorkel that is the restrictive part. if you hook some 3" or bigger pipe up to the stock air box, it works great..

  I saw that with the pics under 'air'. So cutting a 3" hole into the front clip top or side (where air intake is now) and running the PVC or 3" hose to the original air intake on fender will make a difference? Or leaving the original size and running a bigger hose/pipe should work as well, correct?  And if the stock clips wear into the manifold, should I just run a nut and bolt in their places to seal?  Thanks.
  
  Stay safe, stay well. Jimmy.

  no, leave the clips on the box, dont try and rig something up yourself. just because the stainless wears on the aluminum a little, doesnt mean its gonna hurt a thing..
  
  and yes, get rid of that stock intake snorkel coming off your air box..
  
  mk1 had a long snorkel out the FRONT of the air box..
  
  mk2 had a short, right angle snorkel out the PASSENGER SIDE of the air box.
  
  if it were me, i would REMOVE THE SNORKEL COMPLETELY. the snorkel is the BIGGEST restriction. you could have a 12" air intake all the way to the snorkel, and its still only gonna flow what that snorkel will let thru..
  
  if you wanna get rid of your intake restrictions, then remove the snorkel, and throw it as far as you can.

• cut the factory intake manifold and have that full factor air fillter sticking out the hood pointing into the wind, lol, trim the black plastic to where its just enough to hold the air filter in 
  
  
  ok, so please dont REALLY do this based on my advice, although it would probably force a lot of air in, there are probably better ways.

  once again the stupid myspace site won't keep pics going. I will get one and post it up. I think the most important deal with my setup was the forced air part. It really rocked going down the highway when the highway speed air was running into it.
  
  
  
  
  
  
  It all could have been done with aluminum intercooler tubing and if I did it again that is what I would do, but this rocked the Flat Maroon Bunny.

• whats better the td stock airbox setup into fender or one of these ram air things through the grill?
• #12 by Trips_B on 18 Apr, 2012 20:08
• They are 2 completely different intake manifolds.
  
  You cant use the NA manifold on a TD afaik

  yep..
  
  and you cant use a TD air box on a n/a either..

• Utilizing the description by Damac, I think that "one of these ram air things through the grill" will help induce at least a  messed up/mushed out air filter element, and possibly even "hydrolock" if used during a nice rainstorm! Otherwise, go for it.
  
  Sorry... haven't found the 'good & cheap' answer yet, but haven't given up yet either. The tube really needs a rain-dump curve & pre-drain.
