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...

Then something is wrong with your A4:eek:

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

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.

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'..

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.

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.*

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?
