Great pics guys, can't wait to see this come to life!!!

[sentari]

Another item we are going to do with our friends at www.frozenrotors.com is to do a deep-cryogenic process to the four rotors (already semi truck size for this application!).

Also, the car weighed in at 3300 LBS prior to the built at our local Waste Management location.

Do you have any informaton on the brake caliper adapters shown in this picture?



Who made them? Where can I get them, etc?

Thanks,

Marcel can chime in on this, but they were provided to us via HPA Motorsports.

Some updates from the Project Cam:
Pulled in the shop

Front End Off

Exhaust Out

Engine Out

YEA!!

Engine/Trans Seperation

Draining DSG Fluid Before Removing Clutch Pack

Begin Engine Tear-down

Ready for Head Spacer, New Timing Chain and Tensioner

[xBassi]

stock 3.2 is only
Dyno @ DBPerformance yielded 172awhp 184 ft/lb (DynoDynamics)

that makes me sad from the listed 250hp.. i know there will be some power loss but jeeze thats a lot.. lol

That's a nice and clean shop guys

Following this build along to see how it all turns out.

[abacorrado]

Yea even with a dynodynamics you should only add about 30% so thats around 225 at the crank. Charles Barkley says thats turrble!

[Tempes_TT]

Subed! Cant wait to see this thing roar! Might have to take a trip down there and take a peek!

Free bump!

[sentari]

We will post all the graphs and such for the Dyno. The "shootout" mode read 206/221 (which gives you a little less than 20% crank to wheel loss -- which i believe is normal), which is a bit closer to how other dyno machines will register. I have a B7 A4 with a high-flow cat and a stage II from APR and while very fun and greatly improved, the stock TT VR6 still blows it away on performance (as noted above -- 700 lbs more weight it just too much to make up). That application is listed around 260HP as well...

[sTT eV6]

Fast work guys..
Steve

[trumbled]

Today's progress:

-Removed front and rear braking components
-Test fitted new 8 piston Calipers and 365mm rotors
-Separated head from block
-Cleaned up the engine bay and wheel wells
-Ordered some Roloc Bristle Discs to clean up the head and block (They work wonders)

Tomorrow installing more HPA parts...on a Golf R though* ;D

A shot from yesterday:

[trumbled]

Got creative with some jack stands and wheel dollies*

Then something is wrong with your A4

[R5T]

Any more detail pictures of the Turbo/manifold. ???

[abacorrado]

I'll run the A4 through the same Dyno later sometime. But the TT is lighter by a few hundred pounds and the power comes faster. So 0-60 is about 3/4 second faster.

I'm not trying to hate just saying that 250 lbs doesnt make that much of a diff. stock a4 is 15 sec. 1/4 mile, stock 3.2 tt is 14.5 sec. a chip on the a4 should make them even. i have a GIAC tt225 all else stock and my friend who has a 2007 a4 with an automatic and an APR reflashand he is almost as fast as I am and I am faster than stock 350z's. BTW I think the stock DSG programming limits the power on the 3.2 tt's. Best of luck with the build

[abacorrado]

I didnt realize you had a cabriolet. 400 extra pounds, thats rediculous. I think those times for the tt are a little optimistc however. Most seem to be running closer to the mid 14's in the 1/4. Is the A4 a manual, an automatic or a cvt?

[R5T]

On Monday I'll take more pictures...

It looks like two parts, and not a single turbo/manifold unit.

[sentari]

Here's the manifold: http://www.hpamotorsport.com/exhaustmani.htm

The actual description of the turbo is: Hybrid GT35 Ball Bearing based turbo-w/integrated diverter and waste gate valve. It's an impressive piece of engineering and innovation.

[sentari]

Maybe HPA's Marcel can elaborate on the Turbo.

I'd like to get a new steering wheel that has more beef. It appears the TT-RS, RS5, RS8 has what I want. But what do I need to considering when doing this upgrade? I'd like to refuse the air-bag I have and sell the old steering wheel. Or is this not possible? Plus I have DSG so I would need a European TT-RS etc.... So i'd appreciate anyone with experience or knowhow in this matter to chime in.

Maybe this is what you need..


This is mine and has CF flappy paddles.
The control funcctions buttons have been deleted.

I've been looking at a RS5 Perforated Leather one. it looks thicker, but otherwise the same.

[sentari]

We ordered up the OE TT-RS (EU Version)* front honeycomb grill and some of those european OE aspherical mirrors.* A Golf-R came into the shop with them and they were a 'must have'..

[sentari]

Where did you get that Wheel?

[sTT eV6]

It's from an eBay company called Nexan, try here..

It's a nice addition but not cheap.
Steve

[sentari]

What's the deal with the airbag and airbag harness? Can the current airbag and airbag harness be transferred into a new wheel without issue. It appears there are oval and circle variants of the airbag.... Hm...

What's the recommendation for spark plugs in an FI application like this? I'd hate to miss a small thing like this.

Also, I'm also thinking about the Okada Plasma Direct ignition coils. Radically expensive, but they appear to the shi3t.

Not sure on interchange, I bought the bag and wheel together
Steve

[sentari]

Ok, I'll spare the pictures of the R8 coolant and oil cap.* But here's the steering wheel that's coming (it's basically a bit smaller, fatter, and perforated for his pleasure):* It's the EU version with paddles that you can't get here.*

[sentari]

Ok.. So we need wheels and we are considering the BBS CH-R's 19's in silver. Not too expensive, yet pretty cool (kinda like the TT itself I guess). Tire Rack comes up with 245's for the tires. It seems to me that 255's would work. Does anyone have any experience in this matter?

The important bit is the rolling radius of the front to back as the haldex wont like it if there is too much of a difference.
What tyre manufacturer are you going for ?
Steve

[sentari]

Got a few things back from powder coating.. A little VR6, a little "Viper"...
