I have been hearing that i should put holes in the plugs. something to help with the back pressure in the shroud...is this true?

Why would you put holes into the plugs?? That defeats the purpose of putting the plugs in at all.... I dont know of any delicate backpressures.... Anybody?

There's no reason to put holes in them.

think of the fan shroud as plumbing (it really is). if you drill a hole in the heater nipple plugs on the shroud, then you allow cooling air to escape. all of the preassure needs to blow on the engine.

It's my belief that back pressure caused by plugging these holes can disrupt proper air flow due to turbulence (sp) caused by directional fins inside the housing. Just my $.02

yea that is what i heard too. and they said to drill like 1/2" hols in your plugs to allow some air to escape. its like driving with your heater vents closed all the time, but there are bleeder holes on your heater boxes, so some air escapes. that is why they say to put small holes in the plugs, to recreate this effect.

the air current is created by the fan and the fan is powered by the rpms of your engine correct? if all of a sudden there was backpressure i'm assuming it would slow the fan, resulting in dropped rpms.

just a theory

I would say not impossible,,the theory seems right. I just went and bought a late model doghouse with out the ducts. $25 new at vw swap meet a couple of years ago. It's chrome,,but I don't care. The price was right. Plus,I now have the better oil cooler.

ok

sit down


as y'all said, the fan speed is directily proportional to the engine speed.

the air ducting created by the dog house and cylinder tins is designed to efficiently move air down and across the block and heads. if you place holes in your dog house, you are removing pertinant preassure from the air delivery system to most effectivly cool the AIR COOLED vw engine.

you must REMEMBER that the VW you drive is 100% dependable UPON AIR FLOWING OVER THE ENGINE BLOCK AND JUGS. if the air fails, the block will fail. the engine will seize, and you will be up shiza creek with out a paddle.

your choice.

air or no air..... Very Happy

if my theory is correct(not saying it is) then the holes would allow an engine's rpm's to be unaffect or not as affected by backpressure(not sure what could cause backpressure). resulting possibly in a shorter engine life.=race

if you do not have holes and come across some backpressure and your rpm's drop(probally won't be noticeable unless on a dyno)then your engine will last longer with less performance.= reliability

if my theory is wrong= disregard the previous statements and let me know.

i konw we have a couple engine builders out there, drop a post if you know anything about this hole everyone speaks of.

well the whole thing that im thinking about it this:

When you have heater boxes and you open the channels, you are allowing the air that comes through the boxes to flow away from the engine. But if you need heat then it will be cold outside so the overall temp is going to be lower. Now with the heat channels closed then the air is forced down over the heads. But on the stock heater boxes there are bleeder holes. And these holes allow for some ( not much) air to escape.

My question is do we need to recreate this small amount of air escaping to get maximum air flow, beause that is the way it was engineered, or is blocking the channels going to be fine.

Now i have a 96 plate oil cooler, so if if blocking the holes completely is alittle less effective then im sure that my oil cooler will make up for it....right?

Heater boxes???? what are those? Laughing seems to me, like a little flow improvment is definately better than none. I personally like to err on the side of caution. I don't run heater boxes, so flow is not a problem. try doing it both ways, and see which way works best for you. just don't cook your motor.
