The Nurburgring-Nordschleife specialist, which was fielding a pro class car in the Blancpain GT Series Endurance Cup for the first time this season, took the German manufacturer’s third victory in four years in the classic Belgian event after prevailing over fellow BMW team Rowe Motorsport.
Nicky Catsburg, who shared the #99 Rowe M6 GT3 with Alexander Sims and Jens Klingmann, closed down on Eng at the start of the third hour, before the BMW DTM driver was able to pull away into a 15 seconds lead before the next round of pits
The gap between the two BMW M6s was 20s before the final stops, after which Sims came out with only half that deficit.
Rowe saved time by taking its final joker pitstop — which can be shorter than the regular 1m52s minimum — but the British driver was unable to make a further dent in the Eng’s advantage.
Blomqvist said: “We’re just a tiny privateer team who races around the Nordschleife; we put a pro car in and have gone and won the thing.”
Sims had been under pressure from Frederic Vervisch in the third-placed Sainteloc Audi R8 LMS early in the final hour before a slow lap from last year’s winners put paid to its hopes as the Audi appeared to splutter out of fuel on its in-lap.
The seconds lost dropped the Sainteloc factory entry, in which Vervisch was joined by 2017 winners Markus Winkelhock and Christopher Haase, behind the Land Motorsport Audi in the final order.
Brothers Kelvin and Sheldon van der Linde and Jeffrey Schmidt had been in with a shout of victory until losing time with time penalty at its penultimate stop for a track limits infringement.
Fifth place went to the best of the Mercedes-AMG GT3s, the factory Black Falcon entry driven by Yelmer Buurman, Maro Engel and Luca Stolz.
They lost any realistic chance of the podium when the car pitted under green flag conditions just before all their rivals took their stops under a full course yellow minutes later with three hours to go.
The Auto Sport Promotion Merc squad took sixth place, one lap behind, with Raffaele Marciello, Daniel Juncadella and Tristan Vautier.
Nissan took seventh with the RJN Motorsport-run GT-R NISMO GT3 driven by Alex Buncombe, Lucas Ordonez and Matt Parry.
The best of the factory WRT Audis, the #2 car shared by Rene Rast, Robin Frijns and Nico Muller, was two laps down in eighth.
The sister car, which Dries Vanthoor had qualified on pole position before being excluded for a technical infraction, retired in the final hours with an overheating problem.
The R-Motorsport Aston Martin squad took ninth with the V12 Vantage driven by Nicki Thiim, Jake Dennis and Matthieu Vaxiviere, despite two brake changes and multiple punctures.
Bentley again missed out on Spa victory after having the pace to win with the new-for-2018 second-generation Continental GT3.
The #8 factory M-Sport entry driven by Andy Soucek, Maxime Soulet and Vincent Abril was in contention until a clash with an amateur class Ferrari shortly after the one-quarter distance.
The car retired on Sunday morning shortly after undergoing lengthy repairs after an on-track clash involving the Team75 Bernhard Porsche.
The sister Bentley came from the back after problems in qualifying to run in the top three in the hands of Steven Kane, Jules Gounon and Jordan Pepper until a holed radiator and problems with the right rear corner dropped the car to an eventual 25th place.
