that audi is wild, huge fan of it and laguna
I used to be a regular on this forum from my personal account, TallaiMan, but ended up selling my GT3071R B5 Audi A4 1.8T in 2007/2008, and retired from VWvortex for a while.
I see a lot of new names on here, and wanted to introduce 034Motorsport as a new VWvortex Banner Advertiser!
If you have any questions about our products, whether it's an engine mount set, breather hose kit, standalone ECU, or engine internals, feel free to contact me via PM or email.
For those of us who are unfamiliar with us, we've been involved in the 1.8T scene since 2005, and still pushing the platform to new levels every day.
The 034Motorsport Time Attack B5 Audi A4 1.8T
Our pride and joy, this is one of the fastest time attack cars in the country! Featuring a Precision 5858 CEA Turbocharger, Custom 034Motorsport Dry Sump Oiling System, 2008cc Displacement Tall-Deck Block, and 034Motorsport-Built Cylinder Head, the Time Attack B5 Audi A4 boasts a broad powerband that, paired with our chassis setup, allows it to compete against BMW M3s, Porsche GT3s, Mitsubishi Evolutions, Subaru WRX STis, and Nissan GT-Rs in national-level time attack events.
Feel free to enjoy some videos of the car in action, including some footage from the GTGP at Laguna Seca, where the car was running consistent 1:31.XXX laps...
Glad to see you participate on this forum.
I've been a follower of your project silverlight since it's conception was hoping you would give us some inside scoop on it. In particular, I saw that you folks used one of your own k04 cast manifolds for this project. Are the revised ones about to come out?
I was also I little disappointed in the final numbers. I would have thought you could have squeezed a little more out of the 2871 eliminator. There must have been a limiting factor that wasn't brought forward.
Not beating on you, just would like an education on why that setup was so limited. EGTs perhaps?

Nice I ordered a couple parts from you guys I talked to jerramy
Here's a pic of my build gt3076r
^^^Big Turbo build lots of pics^^^

Welcome back. I've followed your A4, & now GTI, in the Eurotuner GP events but have just read the articles about the A4's development. It's awesome to read about the thought and reasoning behind the parts selected and changes that were made.
I can't wait to stroke my 1.8 so I found this especially interesting…
"To maximize power and response from the 4-cyl motor, at first 034 used a 100mm stroke for 2.2 liters of displacement. A tall deck diesel block was used to optimize rod ratio as much as possible. However piston speeds of this motor were astronomical, the 100mm stroke being exactly twice as long as the average F1 motor. What this meant was that 034's 2.2 would have the same average piston speeds as an F1 at half the RPM. This limited revving to 7300rpm, and after several events was determined that some bottom end could be sacrificed for a higher revving motor.
To meet this challenge, 034 built a new motor based on a tall deck 236mm block, but with 92.8mm crank and 159mm rods, with a rod ratio of 1.7 and lower average piston speeds, this new motor revs and makes power to 8500rpm effortlessly, creating a much broader power-band with an approximately 300rpm slower spool time."
