Ram Air with a SRT hood.

What do you guys know about cutting a circle on top of the stock intake lid, and a circle to match on the underside of the hood. Block the two holes where the air comes through to begin with??? Let me know your opinions.

No one has heard of it I guess?

I spoke with Stephan Zweidler from PVO last week on this exact thing for an SRT-4 we are currently building. Stephan did the work at PVO on the functional hood. He told me it was not worth it, more than enough cold air comes in through the fenderwell to feed the engine. And the scoop dosen't give enough ram air effect to over come it. He said the hood ended up being purely for looks.

That's what I wanted to know thanks.

bump for an interesting find. Was going through some of the pics at srtforums gallery about 3 days ago and found this.

I find it hard to believe you wont get at least slightly better airflow compared to a cai in the fenderwell. A cai to the fener is more covered up on more sides than this setup. Even modifying the top of a stock airbox should give you much better gains.

05srtclone in your case you would just need a dremel with two or three cutting bits. You would have to remove your "srt design" hood insert, cut out the back. Then cut the area around the hood and the airbox.

When i get an srt hood im going to try this.

Yes that is the hood mod i was talking about.

sucks to drive in the rain with that mod I bet.......rain forced through the scoop while driving....and then fed directly into your filter.......I can't imagine that would be a good thing....

People with this mod have had no problem with that.

so far ive only seen some debate on this situation, nothing set in stone

Hey kevo, are there more pictures of that car anywhere? I'd like to see the scoop. I was at work last night pondering a scoop like that above the stock air box and modifying it to make a ram-air setup. I'd like more info, but I am concerned as well about ramming rain.

thats the only pic i found, sorry.

me and 05srt4clone had that same conversation on aim a few weeks back when i posted this. As far as im aware, yes it can be done and it will make a killer ram intake with only a few dollars and a dremel. It can be done two ways. Both ways involve cutting the top of your stock airbox. Each depends on the clearance you have between the hood and the airbox.

first would be to make a cowl out of fiberglass to match up the holes on the hood and the airbox. Using some sort of material simillar to the seals used on the doors and trunk you can make a tight seal.

The other is even cheaper if the clearance is smaller, you can simply use some of the door sealant on both the hood and the airbox to make a tight seal between both holes.

Yes water/moisture has always been an issue with this mod. Not anything concrete but its always on the back of peoples minds. the only thing i can think of is the possibility of using another, much lighter filter material in sheet form on the hood side to catch some of the moisture.

in 05srt4clone's case would involve cutting the scoop insert too, from what i can tell its solid and doesnt have the air inlet or just buying a real srt scoop.

Thats not going to make a killer ram air system. The scoop on top of the hood is too low toward the hood...it will only work effectively at low speeds.....hit a highway and more air will flow over that tiny bulge then will enter it. The GTO had the same problem. There is a reason dragsters put the scoops way above the car...more airflow, less bypass. Don't waste your time leave it stock....Gary knows his stuff.

the srt hood scoop is fully functional. if you look at the pic it feeds the turbo. I dont see how it would make little or no difference if the scoop was plugged, even if the info came from someone in PVO. The performance from the hood was likely not what they had hoped for but its certainly not useless.

For some reason they left the area just about the airbox, possibly because they saw no gains or possibly because of moisture. The few people have already done this with a ram intake have already seen gains. Thats not debated, what is debated is the gains and moisture factor and the use of the stock airbox with it.

Gains are and will be MINIMAL at best. All I was saying is its a waste of time. And no it does not feed the turbo on the SRT it blows air over the engine and the turbo thus cooling them down. The SRT does not pull air functionally from the scoop. Don't get me wrong, its your car do what you want....all I am saying is don't be all ricer thinking your gonna be able to take on a McLaren after the mod.

LOL! quote of the year so far! Nah, im not out to beat the McLaren.

I just want to mod the flux capacitor hood scoop to beat the delorian to 80mph

I specifically ask the guy at PVO that did the design work on the fuctional hood, if I should make it fuctional.

Here is his response:

Stephan@PVO wrote:Don't bother.. It actually makes the engine gulp hot air after long heat soaks.

There is enough cold air coming from the wheel well and there is not enough ram-air effect at speed on the hood scoop to make it worth it.... It would be purely for looks....

You could try the MOPAR cold air intake for bling-factor, though... .hehe It puts the filter in the wheel well and runs aluminum pipe to the turbo.

hmm i guess its not worth doing the mod then. damn

We were going to do it on the Car & Driver car, but we ask the guy who designed the hood and he said not worth it.

So if someone told you not to put on a turbo kit cause the turbo makes a lot of heat, would you listen to them too?

this guy did it to an sxt

"Rain is not a problem with this set up
the stock air box has a drain hole in the bottom if it ever got in. Gains with this mod are very small but noticable 1/2 way through 2nd through 5th gear."

No I wouldn't listen to them, I would tend to believe that guy had not been around cars very often. No one told me that anyway, so it is a moot point.

I do trust my friend, Stephan, the Chysler engineer at PVO. He is in a position to know. One he worked on the SRT-4 project, he specifically did test for Chrysler on the effectiveness of making the hood fuctional. He had access to a lot more resources than I do to repeat the experiments, and most likely come to the exact same conclusions.

Stonebender · Post by **Stonebender** » Tue Jun 28, 2005 1:59 pm

I've read a few magazine articles on the development of the SRT-4. They all say they designed the hood with ram-air induction in mind, but scrapped the idea because it didn't make any difference. I think it was Road&Track or something sometime in 2002. But yeah, I'd have to say Mr. Howell is correct.

fflores · Post by **fflores** » Tue Jun 28, 2005 5:12 pm

It is not functional as far as "Ram Air" set up... but does provide some cooling for the turbo... according to Ethan from PVO when we talked to him at Nationals.

TwistedTunerz · Post by **TwistedTunerz** » Fri Apr 25, 2008 3:14 pm

^^^ thats right..the WHOLE point of the srt hood is for TURBO COOLING...if you run a srt spooling hard it will heat up even glow if your beating it.... the whole point of the hood was to keep temps down not for an air intake at all hense the reason the only outlets under the hood are aimed at where the turbo would sit and thats also the reason the srt-d has the duct BLOCKED off because it isnt functional for a non turbo application, just like the reason the srt-d has a diff. front bumper...when the srt-4 was being designed they noticed higher engine temps when they had it on the track so they adder the extra "nostrels" near the headlights this lowered the temps down so they fixed it but they already started production on the other bumper and had an excess of parts hense the reason for the sxt / srt-d was a way to get rid of some extra parts and give away a "clone" without the power and get some extra $$$ if any of this was fuctional they would have made the change so clearly this isnt very fuctional...plus from a factory view why would they suggest cutting a hood so that you would have to take off the lid of the air box or cut a hole in it?? none I wouldnt cut into my hood for a tiny bit of extra air to come into a sohc that already gets enough air....people running 60mm throttle bodys on the stock air system dont run out of air so why try to bring more in ? its the same temp. air so its not like your getting colder air..kinda pointless in my views

I ran the ram air setup on my R/T and there was significant gains over 55mph when the ram air effect would work. Of course this mod won't help a forced inducted motor to well, it definitely was a clean looking cold air setup with the functioning hood
