Hey, finally decided to make a build thread.
So, "short" run down of how it has all come together. I had the car with just simple bolt ons and tune running 218whp and 289wtq on 93oct (dynoed on a cold night on dynojet). There was a local distributor of Arashi turbos that offered a total of 2 prototype kits for Kuro GT2554R turbos (basically the same as an MRX) for a very affordable price. I couldn't say no as it was just $1300 and included catless DP and hot side charge pipes with all the adapters and lines for the Fiesta ST. The cars final numbers on the set up where 280whp 300wtq on 93oct and 335whp and 322wtq on E50. After nearly 2 years running the turbo and reaching it's efficiency limit there appeared to have been lack of oil in the turbo at a moment where it was on high boost and the front shaft snapped. Went to a reputable local turbo shop and had the thing rebuilt keeping the dual ball bearing but machining and going up to a 2860 wheel/compressor set up.
Went to the Dynojet last saturday and tested the final tunes for both 93oct and E50 on stock map sensor. Peak boost is right around 28.8psi.
93oct:
315whp 321wtq
E50:
372whp 369wtq
Keeping in mind that it's 90 degree weather almost all year round. I'm happy with the numbers. Spools just as good as my friends with GTX2860R (from various tuners) and is basically the highest horsepower Fiesta ST locally at the moment. I've helped a couple of friends install S280s, Whoosh Hybrids and other turbos and ridden in all their cars. I've gotta say there is no replacement for displacement (of air volume from the turbo)
.
Roll Racing:
Been to 2 roll races at the local drag strip. Starting from behind the burnout box and taking off full throttle just before the beams up to the 1320ft finish line. Ran 115mph with a previous 310whp E40 tune with the 2554 set up. I'm hoping to trap 120+mph when the next event is given an official date after this Covid19 thing blows over a little bit. As reference a friends FoST with 370whp trapped 112mph cause it's pretty laggy and mild bolt-on Coyote Mustangs run in the 114-116 range. Had originally started to build the car just for fun and having a fast-ish daily but Roll racing is very fun, and LEGAL.
Made 117mph on my last trip with a soft tune in 2nd gear. Will be back later in the year with better tires and stronger tune down low.
