JTD-Performance

After one month of driving the prepared Giulietta QV with usage of the water-methanol system, we expected that the intake was cleaned quite well. So yesterday the Giulietta was in at H&S Corse to check the power output, and to see how much power we could achieve from this setup with stock turbo. When I received the car the first time it was tuned to about 250 hp / 390 Nm. So with the all the work done to the intake, exhaust and intercooler, without any change in software the car did 266 hp/ 412 Nm. After some mapping the power went up to 320.7 hp ! Quite an amazing figure for a stock turbo. Several efforts were done to reduce the torque, as it tends to go to 480 Nm easily and the clutch is not upgraded so far. Serge managed to get it down to 443 Nm. Very pleased with these results and many thanks to H&S Corse for their mapping and dyno service! ... See MoreSee Less

After having worked at many Alfa's with JTD engine, we were asked to do a power transformation for a Giulietta QV. The idea was to keep the stock turbocharger (for now anyway 😉 ) and to optimize all the relevant parts to get the best possible performance with this setup, but with a stealth look and sound. So we mounted our intercoolerkit, replaced the stock airbox with a performance airbox with cool air infeed, mounted a full stainless exhaust line with 3" front section, sports cat, and 2.5" centre section with Ragazzon rear silencer. And last but not least, to keep the intake valves clean (disadvantage at direct injection engines) and increase power even more, we fitted a SnowPerformance Stage 1 water/methanol injection system, with the WMI tank placed in the engine bay.
Let's call it a Giulietta QV, the "JTD-Performance way".
The first results at the road are very promising, but to see the real potential, this car will be mapped and tested at the dyno very soon, so stay tuned for more updates!

JTD-Performance

Newly available for the 166 2.4 JTD 20v, the JTD-Performance intercoolerkit. In general, the need for performance parts for the 166 is less compared to the more popular 147,156 and GT JTD, but fact is, that the Alfa Romeo 166 coupled to this 2.4 20v euro 4 (version without DPF) engine is one of the "tastiest" JTD's available. This engine, which is basically the same to the ones found in 159's is very tuneable, and the total weight is approx 100 kg less for the 166. However the weak point for the 166 is the stock intercooler, and that's where this upgrade comes in. On this car we were able to drop the intake temperature with 25 degrees during a 4th gear log. Looking at the temp curves, it is obvious that the difference is only getting bigger at longer durations of full throttle. After a remapping session, the torque curve shows a broad band close to 500 Nm without any visible smoke output. It makes this 166 an elegant powerhouse! ... See MoreSee Less
