1st Gen Probe - Ram-Air pics

[Duddy]

Few things I thought of while typing my last post:

Stacey, you might want to get a spare hood from a junkyard and whack a hole in it and instal a NACA duct in it, so that air only has to travel a foot at the most before entering your intake system. NACA ducts are the most aerydynamic form of "scoop". Just a thought. Before I joined the military, I had planned on turning my car into more of a race-only car, and I was going to install a naca duct in my hood.

love the SCCA sticker

Another thing, I remember watching some import drag racing on TV a while ago, and the all-motor guys have intakes actually sticking out of the front of their car almost a foot. That's some pretty hardcore ram-air there.

I had something else to say, but I forgot it. Crap.

Anyways, 'grats on the ram air, keep us posted about it!

ok ok ok easy people

Well I have to reply..

The controversery was over the price ... ok then I did cover that in a post way back from here. And I gave some examples of why it is so costly. I guess my long posts are to long to be read completely.. I'm sorry for that..

As for Performanceprobe.com I personally dont have a problem with that website. They are them and we are we thats about that.

Using the shop vac extenstion is a good idea, but your only going to get 2-3/4" opening for the air to rush into. Which is fine for a lot of people.. its fine.. But if your looking for the most gains possible then you have to have a larger scoop to collect air.

As for the amount of bends and the overall length of the ducting. I was curious about it as well so I asked the Process and flow dynamics engineer about it. He replyed that it was well thought out and was fine. I shouldnt see anyproblems with this set-up.. If thats not convincing enough I dont know what I can do to prove to you guys that I really spent some time working this out.

Also this should be considered a professional set-up. With a professional set-up price tag. I did my research (engineering)and purchased the highest quality parts and that inturn created a high price tag.

As for using a short run and a NACA duct. I was going to use that idea but cutting up a hood would not make this a buy a kit and bolt it on project. Also the negatives with using a duct on the hood didnt satisfy my overall criteria.

* It had to be a bolt-on type kit.
* It had to be of the best materials possible
* It had to be flexible in mounting location
* It had to have detailed installation instructions. So it would be easy for anyone to install it at home using common tools.
* It had to be functional - Not just bring in cold air - The performance gains had to be felt, not imagined
* It had to have real numbers to show to people - (I Havent documented them yet.)
* It had to be easily removable or transferable from one car to another.
* It had to use the stock air box mated with K&N filter
* Cost could not be $100+
* Safe concerning water injestion

I'm sorry if some still arnt convinced about any of this.. I've done all I can, next to posting Pilota tube readings. Which I still may have to do.

Oh well love it or hate it.. everyone is entitled to thier opinions and they can always express them here on ProbeTalk.com...

I would also point out that there's no proof that shorter hoses would add more power than longer hoses. As an example, take two ram-air systems like Stacey's, with the same scoop, but with long hoses on one car and short hoses on the other. Since the scoops are the same, they will draw in the same amount of air. And regardless how long the hose is after the scoop, the pressure within the hose (and thus within the airbox) would be the same.

It's the same principle with a garden hose. No matter how how long the hose is, you still get the same force of spray out of it.

The only possible disadvantage to long hoses is that they could collect more heat.

but doesnt a longer hose mean more resistance?????

Only the number of bends, the angle of bends, and the turbulence within the ducting should create the most resistance.

Only in Electricty.... ((giggle))

Seriously tho - Yes but unmeasureable at the length I'm talking about and not a concern because i dont have any hoses makeing 90+deg turns. When air changes direction that severly it causes turbulance.

...But, I will give you this. You did a good job of posting a forum on some random HTML using a page editor. Good Job there. [/B]

<sigh>

you just don't get it, do you? alas, for you do not.

i've seen the posts on PP and i'm really not surprised. steve thinks i'm an asshole and that's that. he doesn't know me and probaby never will. his choice, not mine.

as for who owns this site, it is co-owned by two individuals: Racy-Stacey and myself.

stick on topic here and your messages won't be removed.

that is all, we now resume regularly scheduled programming.

Keep us updated on the results from Autox

It just made me think of that, becuase of your garden hose example, garden hoses have much smaller area, so length does play some role

I plan on adding a form of ram-air on my next probe It works, and you can do it easily and inexpensively, which categorizeses it in the "do soon" file in my head

very nice set-up stacy!! have you had any buyers yet? cause im very, very interested. i recently took off my HD setup because after only 2 weeks the bottom started to rip bad. if there is no need to cut the front bumper (as seen in your pics) then you can consider me a consumer whore cause i love this.

Re: 1st Gen Probe - Ram-Air pics

You should borrow a vacuum/boost gauge from someone and see if this setup really does pressurize the intake air. Anything is better than stock and under $100 for something that meets SCCA guidelines is great. I'm just curious to see if it really does function as ram-air of if it's just a good CAI.

Re: 1st Gen Probe - Ram-Air pics

with my ram air system my car does lean out, actually quite a bit me thinks. When I took out my spark plugs for a compression check the tips were pure white, which never happened before the intake.

I'll take some pics soon and post 'em.

Re: 1st Gen Probe - Ram-Air pics

The ECU should compensate for the added air and correct the air/fuel ratio as needed. I suspect something is wrong that is making your(deyan) car run lean.

could be.. I changed the fuel filter, so soon I'll change the spark plugs and see if that helped out a bit..
