<center><img src="http://pictureposter.audiworld.com/25140/a_elec_fan_kit.jpg"></center><p>Mario Cascant installed the EFK recently. After installation, he got a CEL which put the car in limp mode; although he did not elaborate, he believed it unrelated to the EFK itself based on the VAG codes he pulled. I asked for details, but he has not returned my e-mail on that question. If he's correct about the VAG codes, it's likely a problem with the other parts he needed to take apart during the install rather than the EFK itself.

I know Scott has a custom EFK made by Lloyd at TDL; Lloyd's is heavier duty and more expensive; more parts too. Lloyd does not know if he will put his working prototype into full production, as he has become very busy with his second job at Cosworth, making R&amp;D time hard to come by when you have to scramble to find time to fill orders.

Anyway, please chime in regarding anyone you know who has successfully installed the popular Evo MotorSports EFK on the 12v.

Thanks!

along with hoses, water pump, Thermostat, T-belt etc while I was in there. I used the 14" Spal fan, same as Evo but made my own brackets and removed the viscous pulley and used a shorter serpentine belt (why spin it if it's not doing anything?).

No probs at all and there's no way possible an electrical hookup on the AC/radiator sending unit relay could throw a CEL.

Definately a worthwhile mod... more power (especially on hot days when viscous coupler is engaged) and quieter too.

Cheap enough at $100 (fan) and anyone with a drill, tin snips and some 1/16" thick x 1/2" wide aluminum (available at larger hardware stores) can make their own straps in 10 minutes. I forget the size of the serp belt required but I can read it off my car if anyone's interested. I only use this car for testing TB's so I doubt it's had 200 miles put on it since I did the fan.

Im in the process of replacing all my control arms, all eight of them. While im at it im also doing the tie rods and ends and was thinking of going with the adjustable upper arms from AWE.

Im trying to get some good info on a urethane bushing setup to do now while im in there and have the parts laying around, ya know?

I remember a while back you mentioning this type of bushing setup and was wondering if you had any impressions, thanks.

Bryan-

Let me know if you want some pictures or anything (not installed).

I might go for the powerflex bushings myself.

Ill let you know when I get them and about to put them in, help each other out a little bit.

other suspension work. So take lots of pictures for me!!!

Do you have a press? I'm assumming that the old bushing will need to be pressed out and the new ones pressed in. If you do have a press, let me know what one that you have. They seem to be pretty cheap.

I also removed the fan clutch pulley and used a slightly shorter belt. I installed it when I did my timing belt service, too.

And do you remember what size it was..

If I knew the size of the belt, I might be able to find an OEM belt that fits from either an Audi or VW...

The urethane bushing set-up performs superbly; you really get some good road feel without the passengers feeling much of a rougher ride. The front end really tightened up well.

On the down side, you need to learn to live with the urethane squeaks. It's not very loud or obvious, many passengers do not even notice it. However, it's always there telling you how the suspension is working. If you like audio feed back from the suspension, urethane can become your best friend as it lets you know exactly what's going on. Alternatively, if you like a quiet ride over performance, I would recommend against it.

The powerflex kit uses the two best types of urethane--the purple and the black. The black is graphite impregnated--it helps reduce the squeaking factor and is harder; the purple is self-lubricating and softer--same purpose of reducing noise.

The red, orange, and yellow stuff that most places use squeaks LOUDLY, because it's TOO HARD. I have heard of many people removing these harder compounds from their ricers and 4x4's, because they could not handle it.

Installing them?

Whats involved, and where do they go?

Im just getting to know them now.

About the squeak, would a little tack lube take care of it, maybe even a lithium grease?

It's actually packaged in the Mcdonald's style ketchup packets.

The hard part is getting the old bushings out. You can burn them out, press them out, cut them out. Whatever works best given the condition of the bushings.

The bushings powerflex makes available are for every radial joint except the lower front. Since it has a three layer metal sandwich it works pretty well. The rest are two layer metal sandwiches; one metal sleeve around the center bolt, rubber, then the second metal sleeve around the outside of the bushing.

The uppers use the black graphite impregnated urethane, as does the shock absorber bushing in the middle of the lower control arm. The lower rear (tracking) arm uses the purple urethane (it's a big one). In fact, all the urethane bushings are bigger than the stock bushings.

As for the squeak, I lubricated mine well. However, its the nature of the beast to make a little noise. I have grown to actually like the sound, because it's far less intrusive than a metal squeak and gives you great audio feed back that you cannot get just from the tighter suspension feel. You will change your turning habits with urethane, because you can both tactily and auditorily sense the suspension's movements and deduce the limits of adhesion far before you even chirp the tires.

Like I said, I like it, but I can imagine that other people will hate it.

I fabricated one in '99. It's been fine ever since. I have mentioned it in a few post - including a recomendation to Clark to do in EFK instead of other wacky mods he was proposing at the time. Oldies may remember Clark that used to post in the performance forum and occassionally get creamed :) He eventually started Turbo5 then MachV motorsports, who were the first to offer EFK for the 1.8T. I'm sure if one was diligent, he would find my post to Clark on the performance forum hehe. I'm lazy.<ul><li><a href="http://forums.audiworld.com/a4/msgs/1138558.phtml">Here's a mini writeup I did for some folks who needed wiring assistance</a></li></ul>

the stock belt is a 1873mm and fit fine without the fan clutch pulley. IIRC, germanautoparts did not have that exact size but had one that was slightly longer (by a few mm) which worked. I would not go any longer than that. The size is a little flexible because of the tensioner.

BTW, my ETKA catalog also lists a 1882mm belt which will probably be a little too long wihtout the fan clutch pulley.

I believe it's the same one the 100CS uses or the 2.8 model with stock dual electric fans.

The size is 21,36X1863
