The top minisprint driver in Australia with 50 career wins and 4 championships was looking for more corner exit power coming into this season and chose to go with my line of High Velocity Intakes for his 2010 CBR powered Henchcraft. He's had some engine issues so far this season which have turned out to be a bad electrical connector. This weekend is the first time he has been able to run a full event with the motor firing on all cylinders and below are his comments after the race.

Hi Monte,...how are you over there ...where do i start....has anyone said that your intake is toooo good...man im having trouble hooking this car up when it gets slick,it just has too much power and im spinning wheels and frying the rear tyres,...have you heard of anyone over there having to change setup for the better power from your intake.....ive come to conclusion i have to do more to get the power down...for the first time this season everything went well ,had no issues and completed the meeting...a 4th and 2nd in the heats...started 12th and ended up 5th...just had no grip the last 6 laps of a 15 lap feature race...im going to a mates place who is very knowledgeable about setups and has a set of scales so im going to scale the car and see what we have...very happy with the performance just need to get the setup much better to get better results...might have to go softer in the bars to get more traction ....thanks again and take it easy...

Do you make these for r6 motors?

Have had people ask about doing something for one but on one has stepped up to the table to make it happen. The exact same design criteria and goals apply to both, do everything possible to improve torque and keep the package light. End of the day your never going to get anywhere with the stock stacks.

LOL..no I haven't done anything with carbs. I fully understand the 600cc engine guys prefer so stay in the dark ages but the rest of the world has moved on.

Heres a few pics of some ancient history.
20 years ago my family had a Honda F1 powered 600 micro sprint running alky with carbs. When it ran it ran semi OK but never ran good and the carbs were usually to blame. It got to the point where it was either sell the dam thing or do something to fix it.
My sand car was turboed on alky with a Haltec ECU and we elected to go the same way. A simple plenum with a single butterfly and a Haltec ECU.
There was very little room to work with do to the chassis design, this is as tall as it could be and the air inlet was positioned in the only space available. When we finished it and got it on the dyno it made better power then the carbs hands down and we never had another fuel issue on the track. As you can see its got some war wounds and I didn't certainly didn't bother to clean it up..LOL
When we sold the car the carbs went back on and the ECU went on the next buggy I was playing with. This bit has been sitting in a box full of old race bits for the last 15 years.
