Is that true? I'd imagine there are more instances of flooding though and that's the main risk.
Air intake ?

With my old Honda cold air intakes with an open cone filter in between the wheel arch and bumper were a favourite for lots of cold air to be sucked in as apposed to engine bay located filters susceptible to heatsoak and sluggish acceleration. To combat hydrolock you can buy hydroshields from a company called injen. They allow air to pass through but prevent the filter getting wet. Great piece of kit
A little video showing you its effectiveness:

Looks good. However, I would need to be convinced a 4.2 V8 couldn't suck water through the Hydroshield before I put one on. Also, how much would it comprise airflow into the filter? Would it become a filter itself and start to block?

Are you saying its an easy bolt on replacement setup that would eliminate the hydro locking issue?

On the same page Benny.
I want a video of this connected up to a hoover with the bag submerged in water. Only problem is we'd need a wet vac to test it - anyone got one?

They have zero affect on air flow, and to be fair even if they had a slight effect you may lose at max what, 5bhp? but lessen the possibility of hydrolock. Perhaps something you could just fit for the winter months when your unlikely to push the car to its limits and miss a few horses (if it has any air flow issues at all which i believe it doesnt), but reduce the chance of the filter getting soaked in bad weather. They do state they're water repellant not water proof but every little helps

Technically that simply cannot be true
It's a mesh, so the presence of the mesh will limit the airflow (Probably not by enough to notice, though). If the holes are full of water, then that *has* to go somewhere. Suck hard enough, I can't see that *some* of it isn't heading into the air flow.

Ok minimal affect
Considering what the air has to get through in the actual filter. Most cold air intakes in that location have nothing between the filter and the elements and are fine, id only be worried about hydrolock if i maybe lived in rural wales or the north of scotland where roads can also be rivers depending on the weather in the winter. The water would have to be at least 6 inches deep for the air intake to be a worry on my mind. At the end of the day they design a lot of cars around the world with cold air intakes behind the wheel arch and im sure they know about rain, its all about personal risk and the need to gain the extra horses here and there by altering/changing things with your own car. I used to spend thousands eeking out everything i could with my old car but then i bought the 4200 and just wouldnt risk it with its potential costs if things go wrong. Its a great car as it is

I mostly agree with all of that These things do have something of a reputation for hydrolocking if you hit standing water, however. I think the critical depth may be a bit less than 6 inches. In the recent rain here, there's been plenty standing water that's worried me (although that may well be unfounded)
It's one of the few things i *might* do, but with all the other stuff I *need* to do, it's quite a way down the priority list

I dont think these are to prevent hydrolocking an engine, more as a shield to stop the filter getting wet "hydroshield"
It may prevent hydrolocking though, resulting in the engine stalling when it wants air, but can't can't get enough trying to suck through the wet cover!...then you will worry that you have hydrolocked the engine!!

Comparing the two explosion parts drawings - yes
Main issue is getting adequate airflow to the Trofeo set up as the cone filter sits behind the radiator. I will try and post up side/side drawings
From memory, the race car has less obstruction aroind the air filter cone ie side covers etc plus it may have hood vents - need to revisit

Hi Adam, unless I'm mistaken the 4200 Trofeo never had a bonnet intake, always under the indicator, as the road going car. The reason being that the intake is side entry and has to accommodate both the TB and the MAF sensor housing. The GT intake is front entry, and in combination with the engine being set further back and no separate MAF means the cone filter can sit directly in line afront the TB on the Trofeo car.

Lol dont get me started on my to do list, only this week had to fix a crumbling pre cat situation. Something isnt right with the aircon, my geo needs sorting as the front toe and camber is helping wear the inside of my tyres to a need replacing level and i have a stone chip crack in the windscreen from a lorry on the m25 last week. July is a winner month so far. Might treat her to a new air filter to make her feel better lol

Re bonnet - correct
Side by side diagram show the two set ups ( I will try and get Matt to attached as file as the forum wont allow an upload due to size) - only difference being part nos 7, & 30, 31 on the Trofeo diagram ( less the redundant bits from the std car). The Trofeo is aslo stripped for weight saving ie no aircon bits etc. which provides more engine bay clearance.

Also there was a quite and extensive thread on this topic not long a go , see if Matt can merge the more salient points.
see thread: GS and 4200 air intake
Finally, love to see any close up pics. of the Trofeo set up - anyone have?
