I am curious to know if anyone has made plans to add special features like Lambo syles doors?
like this??? http://www.carid.com/2006-subaru-impreza-lambo-doors/vertical-door-kit-45343.html

If not this... what else are you adding?
Wings?
Aero?

If so whose are you choosing & why.. or home brew?

Here are some things I plan on doing:
- Motorized Lambo Package
- Traction Control
- Multiple "Modes" (Like on a BMW Z4, Drive Dynamic Control)
- ISIS System
- Some custom interior work, maybe a little exterior to make it look more like one of Vman's rear end designs
- Other bits and bobs that have yet to be determined yet......

I've been quietly watching the development of the car and am still on the fence, but that was my train of thought. Maybe a GT35R, build some flared fenders into the fiberglass, stuff some tire under there. My 951 works well with 285s squeezed in the front, so I'm thinking along the same lines for the 818.

I was planning on stepping over the doors, based on pics and the thought of door bars for the cage. But if people want scissor doors or backwards doors, whatever they want to build for their car is fine with me. Just means one less car like mine, or one new creative idea I may want to incorporate.

Ok , so we have an open tail shaft , ..... " a propeller " that pops out of a hole and blasts through the lic plate and you can fly off a cliff like those Fiat commercials - you would save big bucks ,on going to Europe.

I do think FFR has "our" thought in mind ,but a business model too. They may in fact reached both ,so we will see "new" "thoughts?" what ever , we are big enough to tolerate an idea.
For me , I have to have some kind of project always going on......... When I was in my 20's , I always thought by 50, I would have a HOT wife that I could drive. Still looking for that kit.

You're exactly right. While I'm more into the performance and driving experience rather than the whole "hellaflush" and "stance" deal all that really matters is that they're diggin' cars and messing with 'em :) Even if I don't want to do the same thing or it isn't my cup of tea I can still appreciate the effort and enthusiasm someone put into it.

I still have one question that WAS brought up in the "Engine difference - WRX vs Legacy GT" thread,,,,,,,,,,,
Would there be an affect on the trans by taking one set of wheels out play?
yes we have about a 1/2 ton out of the burden , but did not the original engineers design the trans for all-wheel drive?
You have incredible torque being applied to all 4 wheels ,but now you have an open tail shaft doing nothing and 2 drive wheels and the burden now sits on only one portion of the trans.
Wouldn't you be open at the very least to seal/bearing problems on the rear drive?
the balance is off. Does this exist ?
An example of this is... If you had not known,,, If you take an automatic transmission car and climb to the top of a very long road ,then drop it into neutral and coast down this L O N G road for miles and miles , you can ruin bearings and seals depending on THAT transmission.

Just a thought

Maybe a transmission specialist could answer this

Outrageous modifications
Think 007
The 818R can have a nice water tight tub. Add belly pan under engine.
There is a lot of room under the front and rear for foam floatation.
Add a shaft and propeller to the FWD adapter that is added to the transmission. Reverse and all gears will work to the propeller.
Use air spring suspension. Add vacuum for marine use.
Add collapsible rudder to the steering linkage.
Modify front nose body work to add some lift. The CG in the 818 is perfect.
Add navigation lights and then let's go skiing.
This is a joke, maybe.

P.S. Add drain plug to tub if you leave the car out in the rain.

You do need some wheel speed sensors for it to work. Not totally sure about the compatibility though.... Thing I like is that you can get it with launch control :D!!!!

For people who love the car's performance, but aren't crazy about the body, I wonder if Factory Five could offer a cheaper kit without the body. That would open some possibilities. Open wheel maybe?

Another thing to ponder: I have no idea how the "thermoform" body panels will be made, but the prototype bodies were hand laid fiberglass in presumptively standard female moulds. I wonder if FFR might use those moulds to offer as an upgrade, hand laid carbon fiber body panels?

Aftermarket traction control came up some time ago in another thread. It really isn't as difficult as it probably sounds. I know it can be done on a motorcycle for less than $1000 (including installation). These systems normally piggyback on the ECU (i.e. can make real time adjustments to the outputs of the ECU), without the need for additional/external sensors. They utilize existing information available to the ECU like throttle input, engine RPM, speed, etc. The real question is whether or not such exists that would work for the 818.

This type of system (stand alone with external sensors) is a bit better at preventing wheel slip (compared to the kind I just outlined). The trade off is the way the intervention is done (cutting fuel) - it can have a harsh feel (I don't know specifically about the RL system, so I'm not bashing them here - just explaining the differences). Systems that integrate with engine management (like the kind I was referring to above) can often intervene less harshly because they have additional ways to scale back power, such as altering the throttle input to the ECU (i.e. it's like you let off the gas slightly), closing butterflies, etc.

Every system & application is different, so I don't think we can yet say which approach will be best for which goals.

Agreed. The system I mentioned was the system that came up in a previous discussion. I haven't actually had the time to look for other systems (if you know of any lemme know though). I've just marked things that I'd like to add too the 818 but haven't decided on specific manufactures/products yet. Still got another 1/2 year to go though!

You think that would be good - how about turbo-anti lag system?
That would be cool, but unnecessary i think. the only cars to use anti lag (that i know of) are rally cars that are 4 wheel drive with bigger turbos than the td04 that comes on wrx's. The reason they use it is to prevent the turbo from "bogging down" when launching since you cant spin the wheels very much. I would think that anti lag on the 818 will just cause excessive wheel spin, but it would sound great. The other problem is that you will eat through turbos since you are igniting the fuel partially in the headers instead of the engine.

VD2021

12-10-2012, 03:09 PM

I think I listed it in a thread about planned mods.

I too was skeptic of how the RLTC cuts fuel to reduce wheel slip, but I haven't spoken to anyone that has a complaint about how the system operates in their vehicle.

If the donor has four wheel ABS then you can use those wheel sensors. There are some compatibility items, which I don't have the Subaru knowledge on right now, but I would expect none of them are present and the system can be installed.

I also would like to know if there are other aftermarket TC systems, for cars, that may be an option.

Maybe we need a separate thread.......I don't think this mod is Outrageous:D

meh. Sounds like a sick motor, more than anything.

Anti-lag isn't for off-the-line starts, anyway - it's to keep the turbo spooling when you lift the throttle, and in between gears. Just what I want on my track car.

12-11-2012, 10:43 AM

Anti-lag would be an outrageous modification, but I guarantee no one here will install it. Anti lag works by allowing fuel to ignite in the up pipe before the impeller (the hot side of the turbo). Not in the cylinder. The flame front and expanding gas keep the turbo spooled up. Reads great until you realize that the pro teams that use anti-lag replace the turbo on their cars every other stage because they've burned up the impeller blades. So If you want to replace your turbo, uppipe, and headers more often then you change your oil: anti-lag is for you.

Don't like lag? Look into twin-charging. You install both a turbocharger and a supercharger. Never-lag! Outrageous.

Wouldn't swapping to two smaller, parallel turbos instead of a single nearly eliminate lag? I know that the SEMA 818 without the body had a stock setup that's similar: sequential turbos, with one was larger than the other.

BMW has an electric turbo which eliminates lag by using a motor to get the spool going, and then lets the exhaust take over. It may be difficult for a kit builder to get something like that.

Many auto makers are now going to twin-scroll turbos with two exhaust gas inlets (BMW for example) to improve efficiency and reduce lag rather than two parallel or sequential turbos like were popular on the 90's Japanese sports cars (300ZX, RX-7, etc...). Then there's variable geometry which are common on diesels, but have been used on gas motors. Who wants to try to install and tune one of these?

I think that the 818 with its low cost, adability and easy paintless body panels, will make a perfect university car. I could see it being used for all kinds of wacky ideas: EV, hybrid, running off of cow manure. Who knows, maybe some university project will make it amphibeous. Afterall, someone turned a Lotus into a submarine. With such a good starting point, a team could spend less time designing and putting together the bits and pieces of a car, and more time implementing whatever whacky idea they come up with.

Not as bad as one might think. Positive displacement superchargers don't follow exactly the same rules as turbo or centrifugal superchargers. They spend more time blowing and less time sucking, making the flow properties of a particular design have less of an impact.

*In general*, it's long and slender for low RPM torque and short and fat for high RPM power. Although modern motors with variable valve timing, variable valve lift, direct injection, and other such leaps are making manifold design a bit less important that it was before.

Turboguy

Anti-lag would be an outrageous modification, but I guarantee no one here will install it.

I don't know that I would put too many eggs in that basket. If I go with a turbo 4 instead of the 6 in my 818R, it will definitely have it. I can do it, I want it, and can afford to run it.

Reads great until you realize that the pro teams that use anti-lag replace the turbo on their cars every other stage because they've burned up the impeller blades. So If you want to replace your turbo, uppipe, and headers more often then you change your oil: anti-lag is for you.

In actual fact they do not go through turbos (or the parts upstream or downstream of them) any where near as a frequently as you say -- but certainly much more frequently than cars without the system.

And that doesn't phase me.

For some people the bottom line dollar is the only thing that matters in building their car. Other people have a different recipe for enjoyment. No one way is more right than the other.

sounds pretty loud, I know at lime rock they have noise restrictions, I wonder if you'd get black flagged for something like that.

Depends on where they mic you, and if their noise meter can react fast enough. If they use an averaged and/or "weighted" sound level meter it might not even register significantly. If a flat-4 ends up in my car, I guess I will find out.

There's a semi local to me guy in Indiana running anti lag on his 02/03 WRX. He hasn't had any problems in 2 seaons IIRC. I think the whole antilag thing is blown out of proportion on NASIOC. 45% scream "OMG awesome" 45% shout back "OMG you'll eat up parts" and somewhere in the middle 10% say "yeah...it's somewhere in between, watch this".

Etos

12-11-2012, 04:36 PM

There's no "system" to install a consumer level anti-lag feature. It's the same one for flat foot shifting and launch control. It's just a tune feature found even in open source tuning. At pro racing level they did(maybe still do) put a fuel injector pre turbo exhaust. So anyone who wants anti-lag can definitely do it very cheap.

The down side is wear and tear, however it's not as bad as people make it out to be. So long as you don't have thin walled exhausts and a none factory turbo most can run anti-lag for quite a long time without any issues. The only thing that will take a severe beating no matter what is the catalytic converter.

Depends on where they mic you, and if their noise meter can react fast enough. If they use an averaged and/or "weighted" sound level meter it might not even register significantly. If a flat-4 ends up in my car, I guess I will find out.

Having been to Limerock after it's latest lowered restrictions, they catch all the loud guys. And it doesn't even need to be that loud. I forget what the actual decibel level is but it's almost street level low. The people living around limerock are extremely rural, hate technology, live like it's 1910's type of people. They hate the track with a passion and it's losing quite a bit of business due to the restrictions. I'm doubting I will be able to run Limerock anymore myself. Some people actually went as far as having a different muffler just for Limerock and I'll have to see if that's what it'll come down to for me.

12-11-2012, 06:02 PM

Well, I don't have to worry about running Limerock with where I live, but my point was that just because you are loud doesn't mean the meter will indicate you are loud.

It depends on both the measuring standard, and the measuring system the track is using.

It is entirely possible that a moderately loud car with an ATL system will register lower readings than one with a moderately louder exhaust but no ATL system. This is because sound level measurements often employ time-averaging and frequency-based weightings, and this can skew things a lot.

They do it on the front straight where everyone is going WOT and are at the loudest. ATL just gives a very fast sudden popping noise between shifts. I actually doubt ATL is going to be louder then a subaru engine with full open exhaust at 6500 RPM.

The appeal of this car is the total lack of "nanny" driving aids like traction control, et al. Raw performance, done by the driver. But whatever floats your boat I guess.Is it particularly unique in that regard? Plenty of used cars don't have that stuff and many cars equipped with them have overrides.

I don't see systems such as this as "nannies". I see them as supplements. It's extremely difficult, if not impossible, to out-preform these systems at their particular task. As great unassisted drivers being accustomed to there input, when your automobile reaches the system's activation threshold, may take some getting use to. But to each his own.

They do it on the front straight where everyone is going WOT and are at the loudest. ATL just gives a very fast sudden popping noise between shifts. I actually doubt ATL is going to be louder then a subaru engine with full open exhaust at 6500 RPM.

Actually, having been at a few rallies where ex-WRC cars were competing and running the system, I can tell you first hand they sound like gunshots, actually. And a pretty serious caliber at that.

The youtube videos really don't do the justice.

Having been to Limerock after it's latest lowered restrictions, they catch all the loud guys. And it doesn't even need to be that loud. I forget what the actual decibel level is but it's almost street level low. The people living around limerock are extremely rural, hate technology, live like it's 1910's type of people. They hate the track with a passion and it's losing quite a bit of business due to the restrictions. I'm doubting I will be able to run Limerock anymore myself. Some people actually went as far as having a different muffler just for Limerock and I'll have to see if that's what it'll come down to for me.

Yeah what a shame When I was there in the end of October I saw quite a few lime rock special mufflers with downturned dolphin tips and baffles. alot of guys were running those beehive baffles too.

Those are race cars with all the bells and whistles without any kind of noise restriction at all. I am talking about a subaru factory engine with a tuned ATL, not a full blown race version. It's literally the exact same noise as launch control.

Yeah what a shame When I was there in the end of October I saw quite a few lime rock special mufflers with downturned dolphin tips and baffles. alot of guys were running those beehive baffles too.

Yeah, I was there the first time they announced that people were going to be present to check dB levels. Alot of people were kicked off the track cause there was no prior notice at all.

Not if it's working correctly, it isn't.

You most likely heard a car equipped with launch control that someone referred to as (or mistakenly claimed had) an anti-turbo lag system. The sound is very distinct, and does NOT sound at all like a launch control system - no matter how many mufflers you install. It just doesn't.

Evan78

12-12-2012, 06:22 PM

I think anti-lag and launch control are being lumped together when they should not be. Correct me if I'm wrong here:

Launch control generally allows the driver to keep the accelerator wide open but engine RPM will be limited, presumably to something below redline.

Antilag employs some method to spool the turbo even when the engine is not under load (i.e. when the clutch is depressed while waiting to launch from rest or between shifts).

If a car has an antilag system, it makes sense to use it while launch control is active, but they are still two different systems.

The OEM Subaru ECU can be setup for launch control and flat foot shifting, but the end result is not the same as a typical antilag system.

Ya'all do what you want but I'll carry on with my old school low tech traction control device:

Simple, low cost, no weight penalty, always activated, works good :p

Again you are comparing a race version(most likely with injectors in the up-pipe) to a system that uses nothing but the tune. I'm not sure of the exact procedure, it's something like every other cycle it turns the spark off dumping fuel into the exhaust. The next combustion then ignites the fuel and presto- anti-lag. I have heard this type of ATL and it's the same sound as launch control or backfire. I'm not saying it's quiet- I'm just saying that an engine screaming at 6500RPM is damn loud with a full exhaust and that most of the time is enough to get people kicked out of Limerock. People are running different mufflers just for Limerock right now.

And again- you're using RACE CARS as your basis. They don't need to have any noise restriction whatsoever, not even a muffler or cat or resonator. I'm talking about a typical car with possibly a cat, and definitely a muffler.

Let's just change the subject before I split it wide open.

Inspiration for outrageous 818 mods: How about a 1988 Toyota Celica All-trac powered by a supercharged Ford 460 Big Block, running twin 8.8 diffs? And converted to mid-engine, no less.

Yeah, I'd love to, but...

It would cut into my 818 budget (and I can't have that!)
It would HAVE to be at least decent on the dunes for me to even consider, and it really doesn't look like it's even capable of being set up for that. The best I could do would be to put higher profile tires on it and run them with very low pressure. I could get around and up hills, but jumping would be out of the question (and I can't have that!)

I am tossing the body, it looks like a kids toy. I will most likely cut the frame and ad about 4 inches of length, 99 to 100 inches is where I need to be. I wish they would print the width. How much HP can that transmission hold up to in stock form ?

you can always get an Albins or Mendeola box ... I believe that the Albins you can get has a 10 inch ring gear ... and comes in 5 or 6 speed sequential. Both are tough boxes ... also Mendeola made a 5 speed for the GTM that has a relatively high HP rating and is fairly lightweight and reasonably priced ... Not being familiar with Subaru .. is that thing REAL? and where can I get one?

12-16-2012, 12:22 PM

Not available to the average guy, yes there is Mendola, the G50 or the old ZF even Audi but I wonder what the limit on the Subaru is, and what the weak points are?

Just looking at some of the stock specs it looks like Subaru puts out 300 HP and 290 lbs of torque , so if Subaru uses this unit as part of a 4wd system does the system monitor torque and distribute it out between the front and back of the car? If so then the transmission may not be able to hold up to as much, being that it is half of the system. It would be nice to know more about this.
