Yet another cold air question
:D I swear I saw this answered before, but I can't find it by searching. So I apologize in advance if it's a dupe. ;)
I won't be cutting my radiator shroud for any cold air intake systems. Considering where I live and that the C5 is my all weather car, I know it would only be a matter of time before I destroyed the engine.
But, I do like the idea of the cold air screens. They seem safer from water ingestion because of the aerodynamics of the car, and hey, they did it on the Z06.
But then, I noticed this in the ask Dave Hill section (http://corvetteforum.cc/askdave/askdave1.htm):
...which makes me go "hmm..." Is he really saying that installing cold air screens increases water ingestion risk? Or am I just reading that incorrectly?
:D :cheers:

The Z06 trades some fuel economy for higher performance, by opening the grille slots to achieve slightly lower engine air inlet temperature under certain conditions. I have notice some owners modifying both fascia grilles and the aircleaner. Owners should be advised that engine damage may occur should they drive through standing water with these modified parts on their vehicles.

Re: Yet another cold air question (chadwick)
Dude, I don't know the answer to your question in Technical terms, but let me say, I have driven my "lowered" vert around Houston as a daily driver for well over a year, in all types of weather, with cold air screens and a Trinflow intake (which sits pretty low, but on top of the shroud), and the only issue I have is the engine bay gets dirty easier. That's it. Hope this helps. :cheers:

Re: Yet another cold air question (chadwick)
I did not read it that way. I read that they are giving up aerodynamic drag (hence the fuel economy). I think his only comment on water ingestion had to do with aftermarket products. BTW, I and many others have driven in heavy rain with a Vortex. No problems. You'd have to drive in at least a foot of standing water to ingest in the Vortex IMHO.

Re: Yet another cold air question (chadwick)
The area up under the air damn is not sealed. It will draw air back from behind the radiator until the water is actually up to the Vortex box. I'll admit that I have not tested this theory, but I believe it to be true.

Re: Yet another cold air question (jschindler)
Just to set the record straight -
He said that he ISNT cutting the shroud - thus how can he injest water through a hole that isnt there.. please re-read..

Re: Yet another cold air question (jschindler)
I was looking at the service manual this morning to see the "correct" way to remove the fog light shrouds. It's a 1998 3-volume manual marked "preliminary," and I swear that the diagrams show a fog light shroud that seemed to have vent louvers along the top (the horizontal surface on the top). This got me wondering as to whether that was the original plan, and whether the thing to do is to cut holes or other openings along that surface. Certainly, it would make it harder for water to get in than if the entire fog light shroud area is open. Maybe it would produce a tiny amount of downforce? Any thoughts?

Re: Yet another cold air question (bparker)
bparker. I re-read his post, you might want to re-read mine. I was clarifying my interpretation of what was in Mr. Hill's post, and related my experience with the Vortex. Someone then allowed as how the water only has to be up past air damn to be ingested - with the Vortex (still replying to my post). I was replying to that post when I stated that I didn't think that was true.

Re: Yet another cold air question (chadwick)
Hey Chad, i wouldnt risk it. The risk vsreward isnt worth it. They did it on the zo6 but look at the filter unit and cover thats being used. I think if you do it water would definitely be scooped up and you know how our freeways are w/water. My 2cents :seeya

Re: Yet another cold air question (chadwick)
The Vette was designed for an everyday driver. That means your Grandmother could drive it to the grocery store. If she hydrolocked the stock Vette, it wouldn't be covered under warrantee anyway. The best thing for a lot of people about owning a Vette is tweaking it a little for more performance. And, for the everyday guy, perforance you can feel by the seat of your pants.. That's what GM does too. Look at the modifications from the 99 Hardtop through to the 2002 Z06. A lot of it was just getting it to breathe better.
I run the RM Racing TwinFlos and RMR cold air screens. It's high and dry, didn't have to cut anything, looks cool and difinite SOTP performance difference. BTW, if you see standing water on the road, don't drive any Corvettte through it.

Down here, flash floods can happen quite unexpectedly almost any afternoon. I'm not worried about coming across the water I can see, it's the stuff I can't see. ;)
