Vtec Mini HS Racing Sweden - Mini Mania      

This is the story about HS-Racing in Sweden.
It started with a dream, a dream to be fast and furious, but most of all - HAVING FUN !
In 2007 a standard mini with a 1000cc engine was purchased, and the fun begun.
Vtec Mini HS Racing Sweden - Mini ManiaIt had been a “lady cup” car from the beginning, so it was almost ready to race, Well not really... After a long winter and a total makeover it started to look like a race car again.
At this point the 1000cc engine had 73 wild and furious horses under the bonnet. The team was very excited and went to the first race in 2008, it ended in with a total disaster with a cloud of smoke throughout the whole pit lane; broken head gasket, and a cracked engine block - a less excited team went home.
Quickly we ordered a new race spec 1380 engine to fit in the mini. In Race number two we ended up in 2nd place and was got received the Rookie of the year award.

In the spring of 2009 we wanted to go faster so we purchased the “sport class” mini we are driving today. It was equipped with a 1380cc and dog box with quaife diff and Yokohama A048, so the traction was way better than the standard mini. It also had Öhlins shocks, the best of the best!
In 2009 we ended up 2nd overall in the sport class.
For 2010 we had to set a higher goal and to win the series and with better pit-strategy we ended up in 1st place.  


Vtec Mini HS Racing Sweden - Mini ManiaAfter one week holiday we started to tare the mini apart and did a total makeover….
At this point we had won the whole series, but with a very big budget, so we decided to change the setup of the car to get more “bang for the buck”..
We found the superfastmini..com website and after many.. really many eMails to Mr BJ and Norm at the superfastmini (thanks for the good support) we purchased a Ultimate MTB2 package with a B16a JDM engine.
At this point the body was ready for a Honda engine, the package arrived and the big build began.  Vtec Mini HS Racing Sweden - Mini Mania

We decided to place the gear lever assembly inside, one of the crew us has a outdoor pool at home and had just build a fence around it and got had some tubing leftover, so we used one of that tubing between the stick and Motor.. success :)

The installation of the engine was really straightforward, except for the electrical, we had some trouble finding the right wire colors in the harness, but after a couple of days we got it sorted!

In (month) 2011 we finished up the car two days before the first race, so we didn’t have time for testing shakedown nor any test days... we had 1hour of total testing and adjusting the Mini at the Vtec Mini HS Racing Sweden - Mini Maniaracetrack before the start.
We now discovered that the shocks and dampers were was good for the street but not for the racetrack. Driving with one wheel in the air in the corners is not good race handling.
We had a minor problem 8 minutes before finish, so it ended up with disappointment for the team but also a kick in the but to get it up and running again for to the next race.
So we hope that our improvements are is for the better, keep an eye on the minitec facebooks site for latest update on our racemini, also www.hs-racing.se

Little info about the race series:

This race series started in 1991 to preserve the race history of the mini and at the same time make it an inexpensive method to go racing.
Every year the BMC Motorsport Club arranges track racing license courses.It´s about 30-35 cars starting in every race, so it´s really door to door racing.

Five races/year at 4 different tracks

4hour long endurance race on FIA approved tarmac racetrack.

6 different classes , standard mini1000cc, Standard mini1275cc, sport mini, Modified mini (vtecmini) , Standard car with a fuel restriction of max 80Liters, Standard car with a fuel restriction of max 100Liters true out the hole 4 Hour race.

Winner in each class is the car with most completed laps.

So you have to do quick pit stop change driver and refuel(30Liter), HS-Racing does this in about 1 minute and 20 seconds, others do it in over 5 min.
