Pics of RalliSpec's new intake and rally Celica!

[SteveS]

Alright guys (and girls), I did it. Last night I snuck into RalliSpec's shop and took a few spy pictures!

OK, reality check. RalliSpec's Dave and Andy allowed me to take some pictures of their Celica and their new intake. I just posted them up over on my site, Lagging.com.

I *know* a lot of you are interested in the intake they've developed. Excellent quality, fit and finish. I don't know if the catch can is going to be standard with the intake, so don't ask. They are NOT selling it yet, so don't ask. It's been on a test vehicle for almost a week, a MY99 at that.

Some of you must be interested in the Celica. It's coming together pretty quickly. They've obviously been busting some a$$ working on it. Too bad it won't be done for STPR this weekend, but soon, soon.

Enjoy the pictures!

The link wouldn't work for me (intake link). Rollcage was fine....

Thanks, Steve.

[SteveS]

Which one? I tried to make sure I checked everything! Shoot......

[paultg]

hey steve, thanks for the great pictures.
The rally car sure is white! (I prefer Aspen white) It looks great. I am amazed at how far they have come. I saw in in Febuary and it was a bare metal shell!
Cool...

Cellica and intake pics still not working.

Now the wrx brake upgrade on 2.5 RS pics are not working...

ME WANT INTAKE, Sorry I mean. Me want intake, Me want intake! Did they have a ETA on the intake?

[R Diamond]

If you are getting the 404 not found error, you're using Netscape (my preferred browser). Load the page with Internet Explorer and it will work fine.

Looks like some kinda style sheet incompatibility.

For those without a copy of Internet Deplorer, here's a link to one of the pics...

If there is a reference to an external stylesheet and Netscape doesn't find it, a 404 is reported for the entire page. I want to like Netscape but they make it so hard!

[Revision]

Hoo yeah, that is a sweet looking intake, but I can't tell where the MAF is secured to keep vibration out. Not to mention any way of isolating the MAF from engine vibration...

But, I guess that is what the heat shield is for..

[bsabaco]

I assume you've fixed the problem with NS then? 'Cause it seemed to work really well for me... looks nice too...

[MPREZYA]

Rallispec (if you read this) I must say that is what I call quality and what we should expect from most manufacturers . I would look at a cost of about $300 guessing on all the parts and such for the intake (am I close...if so well worth it)? One question will there be some sort of heat shield included? Other than that I am very impressed. Oh yeah seeing the Celica makes me want to pick one up for $3-4k and make it my play car.

[Imprezer]

Pardon me, but how is it different from JC, W*R or Minnam system for the exception of the oil cathc can?

[SteveS]

I don't know why Netscape would have a problem. I haven't liked a version of Netscape since version 3 dot something. Sorry about the problems. The page does load an external style sheet (ever hear of "code reuse"?), but the sheet is there. Use it for damn near every page.

The intake is secured quite well. Sorry I didn't get a picture of it. Remember guys, they aren't done with the cold air portion of it yet. They're going to fabricate some type of baffle around the filter.

I hope the pictures do their intake justice. It's fantastic. Not shiny red like the Weapon R, but much better fit and finish.

Hmm, that intake looks exactly like Mark's(Kartboys brother), only he made his himself and had it over 1.5 years already. He also uses a pipercross filter and that welded aluminum adapterpipe. Was he involved in the design?
Just wondering...
Looks good, though.

I'm in process of moving myself (now that's an addiction to this board ) so I don't have time to look at the code, but I'm going to assume it's the different ways in which Internet Exploder and Netscape view pathing in an HTML file. Oh yeah, and on topic, the pics are pretty cool. I'm definitely interested in the Rallispec intake, and I'll never turn down some cool pics of a race car.

[Fmdeadrick]

You are correct Marius my man. This photo is from the SE Michigan RS meet last summer with Fred, Roberto, Yourself, and me.

I have 13k miles of testing without failure, the stock airbox is much more likely to cause (additional) turbulence. The key is in the mounting, and in not having a defective unit from the factory in the first place.

LOL... Too bad you guys have to deal with MAF's.

[TR]

wow, I cant wait to drop by there again to check out the Celica.

[Marius]

I have over 13k miles on mine, which is a small aluminum adapter between filter and MAF mounting and a K&N cone filter. The rest is stock(resonator, "intake plenum"). So turbulences caused by the conefilter is probably not the cause. More likely an unsupported intake that vibrates and (due to the lack of the big volume of the black box)causes backfire into the intake at lean out conditions and uneven flow through the suction of every cylinder.
SCC(I guess) once mentioned an intake for MAF equipped cars that would make the S-AFC obsolete.
I wonder if this is the intake they where talking about.

[STi Sev]

I still haven't seen a reply to Imprezer's question. How IS it different?

[SteveS]

IMO almost all the aftermarket intakes look the same in general for the Subie!

With that said, notice that RalliSpec has a piece of pipe BETWEEN the Pipercross filter and the MAFS. Kartboy's doesn't have this. They are hoping that this extension helps prevents MAFS failure due to the high turbulence right at/after the filter intake. It's theory on their part, but that's why they are testing it.

BTW, the Celica is going to ROCK. I think Dave told me it weighs over 500lbs less than stock, and that's WITH the cage!

Having seen or installed most if not all the intakes available for the 2.5RS we had a couple of goals in mind when we built ours:

1. Isolate the MAF sensor from vibration. We did this by using a rigid mounting bracket from the chassis to the sensor. You can't see the bracket in Steve's pics but its there. Generally most intakes we've seen that even bother to secure the intake mount it to a point on the engine. This subjects the MAF meter to a considerable amount of shaking. We've secured the MAF sensor to the chassis and allowed the engine movement to be absorbed by the silicone hosing preventing most of it from transmitting to the sensor.

2. Isolate the MAF sensor from turbulence. We had some discussions with the head of Subaru's training/development center and we agreed that turbulence right after the cone filter was probably affecting sensor accuracy...if not reliability as well. We moved the sensor approximately 6 inches upstream of the filter allowing the airflow to straighten out a bit (many MAF meters use a honeycomb core to straighten airflow through the sensor...the unit Subaru uses does not have this so it stands to reason it would be more susceptable to turbulence).

3. Improve on the fit and finish of the other intakes available. We made sure everything fits right. We machined adapters to allow us to use correct hose sizing so the hose fits snugly at the throttle body and the MAF sensor. We made sure the positioning of the intake would not allow it to contact either the ABS unit, hood, or the proportioning valve (seemed to be a big problem with other intakes). And we made sure everything required for the intake would be included. Construction is all aluminum...the tubing is mandrel bent 3" aluminum anodized black.

4. Open the hood vent. Opening the hood vent draws hot air out of the engine compartment which lowers the temperature of the air being drawn through the filter which improves power gains. We spaced the stock block-off plate down approximately 2 inches so that air will move through the vent but water will not pour onto the filter.

5. Minimize the heat transfer from the engine to the air being drawn in through the filter by the use of a cold air shield. This piece is the only piece on the intake not ready yet and so is not pictured. Construction will most likely be plastic (to keep costs down...carbon fiber was first choice but would push the pricing way beyond what we wanted).

6. Eliminate the contamination of the intake tract from oil vapors coming through the crankcase vent system. Basically we are including an aluminum catch can (as pictured...yes it will be included) to which all the PCV lines are attached. There is a drain bolt on the bottom...we will leave it to the customer as to whether they want to be creative and try to route the oil back into the oil pan.

So what is the pricing? $350 for the kit. Right now we have 19 systems built...3 MY98, 7 MY99 and 9 MY00. We are currently testing the '99 model and after 2 weeks including a 400 mile run up to STPR and back we have had no problems whatsoever. Run with our N1 exhaust there seems to be significant power gains especially up top. We are currently arranging a dyno test session within the next month or so that will test our intake, exhaust, and cams together and individually. Our car will be converted to 2wd to run a 2wd dyno so results probably won't be comparable directly to the SCC dyno tests.

Do you need an S-AFC? On the MY99/98 versions, current info seems to indicate no. You will need to reset the ECU or the car will not idle after you intall it. We are currently running a slight bit of low-throttle enrichment at low rpms but I suspect the ECU would correct itself in a short period of time anyway. We will get to testing this theory soon. We don't have any numbers on the MY00 yet so we don't know if it will require fuel correction or not. We have not experienced the lean condition that Shiv did. Again, more testing is required as we are relying mainly on O2 readings and seat of the pants feel. We don't yet have an EGT installed which might give us a better indication of how car runs with the intake.

So will we make more then the current 19 systems? We haven't yet decided...the whole project turned out to be considerably more time consuming then we had planned so we will have to see what the demand is like before we commit ouselves to another production run.

And finally...we have applied for patents on certain features of the system...we are that happy with the results. (just a warning to other manufacturers out there).

[Revision]

Looks like I'm blowing another @ $550 in the near future.

(Including a spare MAF.. Just in case..)

[8Complex]

Rallispec, I'm confused.

You're saying that you are tieing it to the body of the car more solidly then other intake systems? Now I can see it being tied down in this pic but aren't you worried about the vibration from the chassis as well? Also, it looks like you're only tieing it down in one spot, which leaves at least one other dimension for it to vibrate in (up/down, also somewhat to the f&r of the car, but it is dampened obviously). You aren't concerned about these vibrations affecting the MAF?

I thought I'd bring this up because if this MAF is as sensitive as I've seen, then in order to keep it from breaking, you have to 'float' it in the car more like the stock intake (which has flex tubing towards the throttle body side, and a box with soft rubber mounts to dampen the other side of the MAF).

Just to clarify, though, I am driving a MY00 with the MAP sensor so I personally don't have to worry about my MAF, though I have been brainstorming with several other locals about it and I think that the best solution would be to completely isolate it.
