drilled airbox

im hoping that the two hours i spent on this will give me at least 1BHP per hole

 

ever think about buying a bigger drill bit?

 

ye, but i thought more tiny holes would make a better noise?

i kinda bodged it up to my vacuum and it sounded good!

Plus i like the Repetative Strain Injury i have now!
my hand is still vibrating from the dremmel!

 

Aye could have done that with about 20 holes

 

in the airbox there is a large spring loaded flap think it's to let the hot air in.
how and when does it open?
is it just pressure?

 

they arnt that smart, i had mile drilled and then put the MFA outside temp sensor in there, which confirmed as soon as you were stationary in traffic, the temps rocketed and took forever to come back down.

the best setup i had was using the warm air intake on the airbox and routing that to cold air.

barely ever went above ambient

 

what do you mean?

 

i put the MFA outside air temp sensor in my drilled air box to see how hot it got.

turned out that it got very hot 40*+ in traffic.

so seal it back up and mod the warm air intake instead.

 

u mean block the drilled panel back up?
i was goin to hook it up to the vents on the wing that are there!?

 

christ, just seen the pic of what youve done lol

erm, youll struggle to seal that up. :S

in short itll be breathing a fair bit of hot air now.

what engine you got anyway?

 

89 gti kr 16v

 

get another aibox...make one big hole in the underside and run a pipe in through the charcoal can hole in the inner wing....run that to under the bumper

 

... and put an electronic supercharger on it?

 

What About The Front Intake That Takes It From Behind The Headlight?
Could Make Something The Go Onto Thatthen Down To The Bumper?

 

???
how?
how much?
where?

 

You can just partition the box away from the engine & run a cold air feed into the box & when your back on the open road it won't take long to cool down as it has a ram air effect.

My holes around mine on the mk1 are huge though none are facing directly towards the engine, infact i put the battery into the boot to free up more air as they are behind them in the mk1 & i then cut a huge hole at the front of it to get more cold air coming in through the front of the car & had a pipe coming from down low under the front valance that would enter into the bottom of my airbox.

 

so fabricate something up to block it off from the engine?is that what you mean by partition?
and drag some cold air from down low into the main intake thats behind the headlight?
I'M CONFUZLED

 

yes you can do that, you have to increase the chance of cold air reaching it more than hot under bonnet air..

 

and even then. it still wont make any difference whatsoever

 

y not?
