Power-Holding and Gear-Banging Improvements

Thursday, January 12th, 2012

The Sigma Short Shift kit from dieselgeek.com is a billet aluminum replacement for the stock shifter.

We specifically purchased a manual transmission-equipped TDI for the strength and reliability over their automatic counterparts, but that doesn’t mean there is no room for improvement. To many VW drivers (including us), the long shift throws from the factory setup seem like they would be better suited for a domestic truck than a German sport sedan. (more…)

Kerma TDI Q Loader and Custom Tunes

Thursday, December 15th, 2011

Here’s our little VW TDI trying to “roll some coal!” There was definitely more smoke on both of the Kerma TDI tunes.

To further enhance the power and performance of our Jetta, Matt Ford (the “MF” in MF Automotive) used a KermaWare Q Loader to flash our engine ECU with a tune programmed to give us more torque and horsepower. After downloading our original factory tune to the Q Loader, it is emailed to Kerma TDI, where a custom tune is written and e-mailed back and then installed in the car with the Q Loader. We received a low-smoke tune, as well as a modified tune, for our engine. When we drove the car on the stock tune, it seemed as if the new Stage 1 Colt camshaft gave us a very modest bump in low rpm performance, but when the tunes were installed, the car really woke up—with a significant boost in torque and horsepower that could be felt from the driver’s seat.

Project TDI Part 2: Cam Upgrade and Timing Belt Replacement

Adding Reliability and Performance

Knowing in advance of the propensity for pump deuce TDI engines, such as the 1.9 L mill in our ’06 VW Jetta TDI, to have cam wear issues, we planned to tackle the cam and timing belt replacement right away. But, before we tore into the engine and started modifying, we thought it would be best to strap it down to the Dyno Dynamics chassis dyno at Bean’s Diesel Performance to get baseline measurements.

VW TDI Spotter’s Guide

Tuesday, November 8th, 2011

The 2010 TDI Cup edition—perhaps the sportiest TDI to roll off the VW assembly line.

Which Ones to Consider and Why

With no end in sight to the high price of fuel, many people are rethinking their daily drivers. And while hybrid and electric cars may be all the rage among the Hollywood elite and the tree-huggers, it is very easy to see that these cars are not the environmentally friendly solution that many people believe they are—since it will take more pollution-spewing powerplants to charge the things.

Project GTDI: Efficiency Increase

Monday, August 29th, 2011

Snow Performance was very thorough in making sure the Stage 3 MPG Max Boost Cooler arrived with everything to perform the install (minus the tools).

Our 1.9L Gets a Snow Water-Methanol Injection and Gains 5 Mpg

For the time being, no more cheap paint or free car washes for Project GTDI. We are now turning our attention to where the Volkswagen diesel needs the most help—our sub-100 hp 1.9L TDI under the hood. (more…)

Project TDI

Monday, August 15th, 2011

The latest project vehicle in the Diesel World stable is this ultraclean 2006 VW Jetta TDI.

Buying a Used TDI for Fun and MPGs

Many of us realize that fuel prices will likely never drop back down to levels we’ve enjoyed in the past. The problem is bad enough that some diesel enthusiasts are considering selling their diesel trucks in favor of smaller and more economical daily drivers. So, why can’t you have your diesel cake and eat it too? You can. (more…)
