Your tire sizing is off. you're 1/2" taller in diameter in the front than the rear. that is WAY, WAY too much. the Quattro system does not like that kind of difference.

Thanks for the heads up, but we did some pretty extensive calculations with a specific tire manufacturer, and it is more like a 1/4" or less difference. So we are moving it forward.

The ol' TTS got a dose of grand decoration today. I got my order from J-caps Online and sorted out my engine bay. The fit and finish on these parts is insane. They are actually precision milled aluminum covers that attach over the top of the plastic caps on the; coolant, Oil cap and dipstick. Simple install took 10 minutes total for all three as you just tighten the allen-head set-screw to fix it to the plastic caps. Quality is awesome, they have fast shipping and were very pleasant to deal with. All around a very good inexpensive mod. Here is the part numbers of the pieces I got.

*Oil dipstick cover (Type B J026)

*Oil cap cover (Type B J019)

*Coolant bottle cap cover (Type B J018)

BEFORE:

AFTER:

HOW TO POP THEM TOGETHER:

-Flip the cap over and press the dipstick handle/cap firmly into the cavity.

-Place the back cover over the screwholes and tighten the allenhead set-screws.

-Smooth and loverly, eh?

Thanks, and I'll be watching what you come up with for inspiration as well. We're like and AA group, except most of aren't drunks with a drinking problem. We're car nutters with modification addictions!

Then that tire manufacturer isn't good with math. Here, I'll help:

265 / 25.4 = 10.43" wide tire

10.43 x 0.3 = 3.13" sidewall height

(3.13 x 2) + 19 = 25.26" overall diameter

245 / 25.4 = 9.65" wide front tire

9.65 x 0.35 = 3.38" sidewall height

(3.38 x 2) + 19 = 25.76"

OR exactly 1/2" difference in rolling diameter. Suite yourself, but I'd be bugging those guys who did the math for the correct tire size!! Or a guarantee that when your Haldex takes a dump......they'll pony up.

How about this. For every mile you drive your rear tires make 783 revolutions. Your fronts make 798.

15 more revolutions every mile IS going to play some havoc on your Haldex clutches.

[iMod.:R]

Nate-
Thanks for spelling it out. I am certainly not the expert in that field, and I appreciate your concern that I don't jack up my car! I'll send this info over to the people that are helping me and see what they come up with.

Good lookin out,
J

[krazyboi]

Nice caps! Will your stock ones fit on my A3?

Edit, nm, I see you have to keep the OEM.

[M this 1!]

great looking car by the way! speaking of Haldex, i have the upgrade plus a rear limited slip and DAMN! really gives the car the abilility to throttle ON rotate

OIL CATCH CAN (Top View)

PCV (cover plate)
The primary reason why modded cars should install an OCT is to prevent impurities in the air/fuel mixture, which will occur during combustion. During high revs, high oil pressure will cause engine oil vapor to seep out from camcover. Which will then be diverted back into the intake manifold to be burned off so it doesn’t harm the environment, by trapping oil vapor from entering into combustion chamber and being burned off. This will not interfere with the air fuel mixture, thus the engine can combust properly producing a marginal increase horsepower.

OCT (installed)
The FORGE Motorsports Oil Catch Tank is probably the nicest one on the market across the board. Fit and finish are very high quality and the addition of the external view tube, which allows you to determine when the OCT needs to be emptied. From what I have read, it takes quite a long time before that needs to happen. When it does, the FORGE OCT has a release valve/plug on the bottom side. This kit utilizes the passenger side motor mount, and just two bolts to install the tank. Forge also includes a beautifully crafted PCV plate that replaces the plastic factory bit. It obviously adds some “sparkle” to the engine bay. Although that was not my motivating factor to get this kit into my car, it certainly doesn’t hurt!

Comparing PCV plates
Mounting this thing couldn’t have been easier. I did it with basic tools and the help of my friend Sean (Uber-A3). We had it handled beginning to end in 20 minutes and we are both pretty detailed with how our installs look and function.

keep it up man, I'm liking how its coming along.

Any news on the NOEM headlight mod?

I am kinda dry after the last 3 mods (write up/impressions on two more coming soon!) so I have to wait on the headlight mod. I hope it's soon.

On a side note N.OEM, what do you think of the rebirth of the forum? It's killer to have this level of activity huh? I'm stoked that all of these positive enthusiasts are keeping it kind and progressive. Good triumphs over evil ya heard me! Yeah

haha, well not always. I get to be the dark knight since I have the blackest car

[iMod.:R]

Well, today I did something i've never done before. I entered the car in a show. DUBFEST 2oo9 has a leg of the show in NorCal now which was held at TST (Tomas Sport Tuning), so my buddy Sean (UberA3) and I went out there to handle biz. He got first in the A3 category and I got 1st in the TT category. We both figured that as a spectator of the show it would be $12- and to register your car for the show and get entrance was only $35- so why the hell not. Neither of us expected to win anything. It was a typical chilled out NorCal vibe, and there were some beautiful cars there, especially the MK4 and MK5 R32's. Dunno if I'd ever enter again, but i'm glad I did i at least once.

Winning for my TT peeps!

Tomas parking lot.

Silly rabbit.

Congrats jason, a trophy well deserved!

[iMod.:R]

When I had the A3, I ran Methanol using the AEM kit and had awesome results. I calculated 2mph in higher gas milage, roughly 35% increase in TQ and HP and it was piss cheap to operate. I started looking into using a meth kit again with this great engine in the TTS and my friend Sean (Uber_A3) and I began brainstorming the best approach during this past weekend.

I also needed to build a heat-shield to help in the heatsoak that the AEM CAI tubing was experiencing. I devised this heat-shield/bracket and built a cardboard mock-up to give to my metal guy. As you can see from the pic, it will do the most important job of creating a heat barrier. It also serves as the base for the AEM Methanol pump to sit on as well as still having enough room to mount the methanol reservoir! There will be a series of 3 mounting holes in the base of the heatshield that will allow it to be bolted up to the bracket that used to hold the OEM airbox.

So I just dropped off this cardboard template and instructed my metal guy to build it out of 11 gauge aluminum, I also specified that everything be done with brake bends instead of welds. The pump (which runs north to south under the CAI tubing) has a cool little mini-cover for the pump that is essentially an upside-down "U" with a hidden "L bracket" type flange that allows it to be bolted to the left side of the heatshield. It helps to conceal the pump, and clean up the engine bay.

It should be done by Tuesday afternoon. All thats left is deciding what color to make it and when I get it back, I'll spray it out.

Ah, hell yeah!!!!!!

UPDATE:

As far as my methanol madness is concerned, I am using the universal fit kit that AEM makes and I decided that due to the enormous cavity left in the space where the old OEM Airbox used to reside, that I would have a heat-dam and mounting bracket build for the pump, controller and reservoir for this methanol kit. I am installing it mid-next week, but here is the heat-dam/bracket in a test fitting before I paint it up. I'll do a full review and maybe a DIY once it's installed. Here it is:

This is a pic of the sheetmetal on it's own. in the center you can see the miniature "pump cover" hood piece and above that is a 5/16 hole for the noise-pipe hose clamp to plug into. You can also see a set of 6 holes that will be used to mount up the meth reservoir against the fuse box.

This is a pic of everything installed for a test fitting to make sure I had clearance on the hood closure, and for the CAI piping. This keeps the engine bay tidy. The pump is located under the cover below the CAI piping, and runs the same direction. The Methanol controller is tucked behind the methanol bottle near the firewall.

<- Jealous, that peice came out great! My meth goes on tommorow but sorry its not gonna be fancy like yours

[iMod.:R]

Fancy? Its just $150- in sheet metal work. I can send you a paper copy of the template or I could have my metal guy make one for you lickity split. He'd charge the same $150 plus shipping. Either way, I am stoked that you are doing it too. Its a great mod, easy cheap horsepower and your engine will stay cleaner on account of it. I'm curious, where are you gonna mount the pump and the reservoir?

J

[alva8193]

i would like to use the washer fluid tank for the reservoir but if that doesnt work out too well ill mount the tank in the trunk and still not too sure about where to mount the pump its self but rest assured i will take some pics of it being installed so u can see

[iMod.:R]

So this is how the final installed kit looks. If anyone else wants to do this set up, I can email you the template I used or I can put you in contact with my sheet metal guy. It's $150 for parts and labor to build it. At any rate I have not decided what I am going to do with it finish wise, but I may get it polished out at some point or high temp black paint. I should really do a DIY on it, because the mounting points were all at different levels varying from 3/4" to 1 1/2" so I just used a pipe cutting wheel and chopped a few pieces of cold rolled steel tubing to create "spacers" to level off the base of the heatshield/bracket piece.

SEE BELOW:

Blue arrow shows where I incorporated the hose clamp from the OEM airbox to support this stretch of noise-pipe. There is enough flex in that stretch still to allow for engine movement.

Orange arrow is where the output feed from the meth pump (hidden under the rectangle bent hood) is routed on it's way to tap into the intake pipe. I followed the hose below that with zip ties to keep it on tidy mode.

Red arrow illustrates where I placed the easy on-off studs which are threaded through the aforementioned spacers to level this piece off. The whole heatshield/bracket assembly can be unbuttoned and pulled out as an entire part in less than 2 minutes with a 7mm ratchet driver. Easy as piss.

I am keeping them for the time being, but I did get a set of 10mm Forge spacers all around and it set's the stance up propa!

get R8 V10 wheels.

[alva8193]

i cant wait for the v10 wheels to become avialable in a quality rep i definetely want them

[NeverOEM]

there were two R8 V10s at my dealer; I think if I had 150k.... lol

I just checked the R8 4.2 and R8 5.2 wheels in the stevens creek showroom.

the R8 4.2 is actually wearing wider rubber on its rear wheels than the 5.2, from the factory.

Can you believe it?

[andykccho]

Hi Jason,

where did you bought this iForged XL wheel? what is the final price that you got it? do you mind to share? So far how about the quality of this iForged wheel?

[iMod.:R]

Andy, sorry for the late response, I have been very pre-occupied with some film projects that have kept me busy. I intend to be around more now.

So as far as the rims. It was a test fit that my friend Peter (who works at iForged) and I tried on while I was down in LA. Those are not actually my rims. As a matter of fact, iForged has a 3 piece RS4 type rim coming out at SEMA 11/2009, and that is what I will buy for the TTS in 9.5x19" all around. I am also planning on ditching the magride system in favor of a corner balanced KW Variant3 set up next spring.

Here is the iForged main telephone line in Southern California.

(714) 484-1070 (ask for Peter Chaney)

Good luck man

[alva8193]

Jason! back on the grind...nice too see ya posting again and cant wait to see this thread grow again

[andykccho]

Wow.... Jason, do you have the latest 3 piee RS4 type rim photos?

[iMod.:R]

No, not yet. Forgestar which is loosely related to iForged is debuting them at the SEMA tuning show in Las Vegas next month. The look just like the Forgestar F14, but they are a true 3-piece version. Should be awesome!

[iMod.:R]

Ok, I need some help from my peeps here. I am looking into disabling the magride so that I can run a corner-balanced Coil-over set up, without lighting up my dash like the Macys in Herald Square during Chrristmas. Does anyone here have any knowledge of that being done, and if so who did it? I'd love to get to the bottom of this, and to my knowledge no one has disabled MRC in the TT2's. I am wondering about in the S6 or RS6 cars or from what I remember it was on some R8's. Thanks in advance....
Jason
