Air Feed on the bonnet

[samcourtney86]

If I were to blend a little air scoop into my bonnet which then had a piece of pipe connecting straight into my viper air filter, creating a ram effect, would this be a good idea. Or would it overwhelm the intake with too much air? Its just if i were driving at 70mph that would be alot of air rushing into the filter. Would this matter? Sam

Surely you could just use a CAF and run that down to the front of the grill? No need to destroy your bonnet that way

but wouldn't more cold air make you quicker

 

[samcourtney86]

well yeh, but im not sure whether you could just ram as much air in as possible or whether this would mess it up? Sam

 

[kully]

it would be difficult as well to connect the caf to the bonnet ....ie pipe getting tangled when opening and closing bonnet , best would be straight to the front grill or down to the bottom imo

And when it rains, you'll suck in a load of water and your engine will go pop.

Well i always thought rain would be an issue, but how come air feed from bumpers dont suck in rain and destroy the engine? I got a spare bonnet I wanted to play with it so was thinking of cutting and blending in a little air feed as its seems hard to get a air feed in the valver engine bay! I feel my filters just sucking up hot air.

What some ppl do is not to fit the viper straight to the caf ....sought of point the caf towards the viper ...... if you get my drift

Relocate battery?! then LOADS of room

Well I cant seem to find a route to anywhere on the front of the car to fit a cold feed pipe. Thats my problem. Anyone fitted one to a valver/williams? Thanks, Sam

 

[Bailey_1260]

Should be one already for the standard airbo, just use that route but go to the paasanger fog hole is the usual way, or like i said, stick the battery in the boot.

 

[kully]

might be remove the fog light and feed it down there

Twin headlight conversion on one side of the car, use one of the light holes as a cold air feed entrance.

seen that one before ...does look good

I've got a viper on mine i've got the cold air pipe just behind the headlight its touching the white ajuster on the right, the pipe is abit squashed your right theres very little space no where else to put it i think easy way that is

Drops of rain in the air that's sucked into the engine is not a problem.

Where rain is a problem with a ram-air type intake is where rain falls into the intake, collects in the air filter and piping then gets sucked into the engine when you start it.

So what you have to have is a section of pipe where the air coming in rises vertically.

That suggests you should have the air intake down load at the front. And that's in fact where the air pressure is highest. In race cars the best place to put the ram-air intake is just above the splitter. But the problem with that on a road car is if you ever have to drive through water. You don't want the air intake below water level or you'll suck water.

So you have to find the middle ground. Not so low that it could be underwater if you have to drive through a creek or down a flooded road, but below the level of the air filter so air has to climb vertically up into it to keep heavy rain and splashed water out, and certainly not on any upper surface like the top of the bonnet where water could come down into it.

very good advice

 

[samcourtney86]

thanks, that sums it up well. I now understand. Thanks again, Sam
