Welcome to the Euroserie Supertwin Top gas homepage.

Congratulations to our 2013 and 2014 champion:

Frederik Kirkhoff Schack from Denmark.

welcome racefans


Race #6 in the 2015 championship: August 28 & 29, Mosten Racedays, Denmark.

A sprint race on the 1/8 mile with usually very good track conditions, and a great big biker party around it. And therefore often attended by Europe's quickest and fastest racers. Like Svein Olaf Rolfstad from Norway with his newly developed topfuel V-twin engine (picture below).

On friday at noon, Ricard Gustavsson from Sweden ran the quickest funnybike on the planet in his quickest time ever at Mosten Raceday: 4.13 seconds!

So no doubt about the track conditions.

The first round of topgas was held thirty minutes later. First in line was Conny Karlsson from Sweden (below) with his turbocharged Harley in homemade frame.

A nice pass, and very close to his best time at Malmö last year, so a good start for him.

Harry van Schie from Holland (below) lifted the frontwheel at the launch, but came down too soon.

Some improvements to the valve train were recently carried out, now Harry and Jaap already have plans to change to bigger cylinders. So the last race for Harry with this set-up.

A great start for Bernd Foit, but problems at top end.

Mats Larsson had some help of topgas racer Stefan Andre to try and solve the gearbox problem that has been bothering Mats all season.

But it failed to shift to second gear during his first attempt, and Mats pulled the clutch and cruised to the finish.

Mats' big tent was also the home of Jan Malmberg's double blown bike.

Jan did 5.38, not bad for this year, but still about half a second away from winning time of last year.

Team BB-racing of Jesse Bohn and Lars Birch Andersen had suffered a damaged cranchshaft at the last race, and had to rush to get it fixed. With the help with spare part of Speedy Christiansen and wrenching by Jesper Thiel they got the job done in time . "That engine purrs like a cat", Birch stated on friday.

But he broke the chain when he left the startline, so back to pits without setting a time.

Defending champion Frederik Schack did a nice 4.8 and had to work to keep it straight.

Chris van Nimmen's gearbox has fresh internals, so a check-out pass for the twin-cam Harley.

Chris went towards the guardrail at the end, and was off throtthe early.

Herman had underestimated the grip at Hockenheim during the quarter finals at the last race, but made did not make that mistake again.

Enough revs at the start and 5.36, place #2 on the list.

John Hanssen from Germany was next and did 6.5

Anders Jensen from Denmark did slightly better then Conny Karlsson.

And a lot better then during the last race.

Jörg Lymant from Germany, just like the last race, still on his "modified" Harley.

Jörg will compete the next race with his topgas bike that has a supercharger fitted.

Christian Bruhn's turbocharged Honda stopped after the burnout, a few start attempts, then he gave up.

Bend Foit checked and found major damage to one of the heads.
He's got spare parts at home, and is motivated to attend the next race, but was a spectator for the rest of the weekend. Still, Foit was the quickest German rider of our class at Mosten.

Some rain came down in the afternoon, so round two was postponed till 18:00.
Olaf Menzi from Switserland had arrived, but took it easy for the rest of the day to recover from the long journey.

Birch made his first full pass, and got on the list with 5.66 seconds, place #7.

Jan Malmberg was not able to improve, but Frederik Schack was.

And Jolink also went quicker then in his previous run.

Hansen improved a bit, but was pushed down to place #10 by Birch.

Jensen, Karlsson and van Nimmen were unable to set a better time, and Christian Bruhn broke the rear sprocket when he left the startline.

And also no improvement for van Schie or Lymant. And the bike of Larsson stayed in the tent.

A walk through the pits and Christian Bruhn got a sprocket from Jesse Bohn and quickly got the damage repaired.

Sunday morning gave a surprise, the race would not longer be a sprint, but a "cannonball" or "shoot-out": the eight quickest would advance, then the four quickest, then a final race for the win between the two best of the semi's.

But first a final round of qualifications was held on saturday morning.

So one last chance to get into the race for some of them, like Olaf Menzi. Olaf was assisted at the startline by team Schack, and was off throttle early.

His 5.9 made him first alternate (while Foit was broken) pushing down Chris van Nimmen, who broke the prime belt and was unable to do better.

So a narrow escape for Olaf Menzi. Chris also feared his gearbox got damaged after the belt had snapped. So he checked it in the pits before going back to Belgium.

Frank Peisker from Berlin had arrived late with his ex-Uwe Kahmann bike, recently refreshed by Jörg Lymant, and Frank made his first pass of the weekend.

And also his last, as he landed at the bottom of the list.

Anders Jensen's bike stopped after a few meters, so he could not improve, but was already on the safe side.

John Hanssen did not do better, and did not qualify for the shoot-out.

Frederik Schack sharpened his time to 4.72 and again had to work for it.

Christian Bruhn made his first full pass of the weekend.

But smoke came from the Honda at the top end of the track, and he landed at place # 11. "That was it for the Honda, this season" Bruhn said. His next race will be on his Nitrous assisted Ducati in the Competition Bike class at Dragday 3 in Czech republic.

Jolink went quicker again, 5.26 and gained confidence.

Birch did slightly better, but stayed at place #7

Malmberg's bike hesitated somewhat, he did not improve.

Conny Karlsson's clutch got stuck shortly after the start.

Lymant was not able to do better then his first pass.

Mats Larsson threw the towel, he did not go into the line-up, but his mechanic Magnus prepaired the bike for the trip home.

So the eight quickest racers ran in the early afternoon, Harry van Schie made his burnout in front of a full house.

And he set his quickest time so far, 5.44, so a sharp opener by Harry!

Because of Foit broken, Olaf Menzi came in as the first alternate. Menzi could not do better, 6.0

Then Malmberg ran quicker then Menzi...

Then Anders Jensen did 6.66. Somebody is going to be sent home now.

Conny Karlsson's 's clutch jammed again, so goodbye Conny, and Harry survives the first round.

Jolink did 5.27, so also on the safe side, and goodbye for Jensen.

Birch did 5.5, advanced and sent Olaf Menzi home.

Then an upset, Frederik Schack's motor stopped after the burnout, and an attemp to start it up again failed.

Alternates Hansen and Lymant ran "out of competition. Then Schack tried again, 5.50 seconds, a poor result for him, that was later taken off the result list (below): A restart after the burnout is not allowed during the eliminations, according to the European rules.

A short moment of joy for team BB-racing, still in the game, but then a big disappointment as they found a broken piston (or worse?), so Birch was out of the race.

A big relief for team Sweden that Jan Malmberg had made it into the next round.

Too bad he had to shut off after his burnout because of a fuel leak. Harry had already run, and had slowed down compared to his last run. And Herman usually saves his best for the second day, and again managed to go quicker. Below you can see Jolink's time on the scoreboard, while Harry and Jaap seem worried.

So just two guys from Holland left to battle it out in front of a full house. The blown ex-Heezen Harley against the StarTwin-Jolink-Ducati. Motec fuel injection against four Italian carburators.

The final rounds were a copy of the semi's.

Not enough power coming from Harry's bike, while Jolink had no problems and took the win with 5.26 sec @ 210 kmh.

After his deception at the last race a well deserved for Herman Jolink.

By setting the quickest time, Frederick Schack (below, right) had picked up enough points to become the champion of the 2015 euroserie.
That's three times in a row!

Congatulations team Schack, well done!

Herman Jolink is certain of place #2, Lars Birch is still the #3, and Harry van Schie jumped to the #4 position, and is close behind Birch.

More news from Mosten:

Our friend and former topgasser Marc van den Boer from Belgium (below) ran his methanol injected blown V-twin in the Funnybike class (combined with Prostock bikes and SSB), and managed to win it.

The prime case of Rolfstad's supercharged nitro-bike does not seem strong enough for the power the engine produces.

Ricard Gustavsson ran his brand new topfuel bike once on each day.

His 4.13 with the funnybike on friday made him the 2015 "King of Mosten", but his new bike will soon go even quicker!

Many thanks to Hitz, Holger (below) and all the people at Mosten Racedays for the fantastic weekend, see you again next year.

The last race of the serie will be mid september, the Winternationals at Malmö Raceway in Sweden.
See you all there.

Newsflash: There seems to be more damage to the engine of the bike of BB-racing,
as you can see on the picture sent in by Birch.
