Dyno day! With the new Stage 3 clutch mounted, engine torque was no longer a limitation for this setup, so that gave us the opportunity to go a step further in tuning. First step was to increase midrange boost, which gave +20Nm directly. After that we looked into more WMI specific tuning, regarding AFR and ignition advance. As WMI boosts the octane rating, these parameters can be adjusted higher with the same level of safety. We found out the 320 hp is the absolute max for the stock turbo. Nevertheless the end result is an impressive max torque number of 490 Nm, which is +70Nm @ 3000 rpm. Topend power dropped a little bit to 315 Hp, but with the enormous torque gain that pales into insignificance. Feedback from the owner confirmes this; the engine feels so much stronger, the performance is at another level now!
Thanks again to the guys from H&S Corse for the mapping and dyno testing!

Beginning of the year we did a 320 hp power conversion to a Giulietta QV. During testing it seemed that the engine was producing more torque than the stock clutch could handle, so this was reduced to prevent slipping. Although the car was performing great with the 320 hp of power, the torque limitation was kept inside the back of the head. How will the car perform when the full potential is unlocked? Also the handling had to be improved as well. So we did a second job, fitting our Stage 3 clutch with new flywheel and bearing, mount a shorftshifter and putting adjustable Powerflex bushes in the front. With these bushes, camber and caster can be changed and it is possible to adjust within the stock specification while the car has lowering springs. With these mods the car is ready for the next dyno session, to see what performance can be achieved from a stock turbo. Stay tuned! ... See MoreSee Less

After a long period of waiting, it was time to hit the track again at the PISTA Trackday, circuit of Assen. Since last year was a “lost” season, not much was changed to the car expect for a few minor things. One of those mods being a larger airbox for improved breathing. So this trackday was a good opportunity to get into the mood for the racing season. As there were quite some Alfa’s at the track Jasper Slop wasn’t able to push all the way, but nevertheless he managed to get an impressive 1:57 at the clock on used slicks. Next time will be at the Zandvoort circuit, which will not be a race but also trackday because of the COVID restrictions. Let us all hope the racing season 2021 can start asap. ... See MoreSee Less

Lately we were contacted by a French customer who wanted to build a bad ass Fiat Multipla. As his Multipla has a 1.9 JTD engine, we were happy to build the performance parts for a complete powerful setup. So GTB2056v turbokit, intercoolerkit, new intake with 80mm MAF and 3.5 bar map, singlemass flywheel with Stage 2 clutch, 2.5" bigbore exhaust with cutout valve and reducer to mount to the stock backbox. We cannot wait to see the end result of this crazy project!!😎 ... See MoreSee Less
