Tried to understand all the interest of late from the UK and was informed about the discussion here on Boxertrix.
A little bit of history.
The idea for the InDuct was borne out of fiddling over the years and applying some of the go fast car technology, or lack there of to the BMW. It is not an original idea for me but one adapted to our bikes.
The R1100S was my first BMW and I thought it would be a bit of a challenge to see just how I could improve and refine the tuning.
I set about relocating the battery on the headstock between the fork tubes to free up space under the tank for a big airbox setup with supply via the normal route that the InDuct now takes. This was a major challenge as I started with sheet metal for the airbox and found the supply snorkel to be a bit difficult to fashion.
I then located a company in Sydney and had a discussion about developing something for stock replacement. I borrowed a bike and had the plug deveolped and with some minor changes I requested, ended up with the first item.
After fitting it, I found the bike ran surprisingly weel and thought a lot of the gain was in my head and my butt. I had a few more made and fitted to some bikes locally and this got things rolling.
I then developed the RT item and the R/GS/RS item as well.
Later I took the big airbox and developed it to run two intakes via the air intake under the left indicator housing. We modified the right side fairing to be mirror image and had two tubes through the tank. Not sure it worked too much better than the InDuct. I should have just fitted the SJ Powerfilter and would have had the same air filter area.
Winger,
To clear up the spat on the Pelican board, it was more with Dr Curve discrediting the fact it would not work at all and stock was best. All this from a guy with a long history of setting speed records on older BMWs over the years. On one he even fitted a tube from the front of the bike to the airbox. Hey, presto, cold air intake.
I have the utmost respect for Chris Hodgson at SJ BMW and know his history for work on BMWs.
My comment when the Americans compared the products was that the Superduct was one piece and while it removed the restriction around the battery, it did not replace the stock rubber section and did not increaase the size of the mouth.
Chris lurked on the board and watched in general what was happening and finally responded politely about not using the board to sell product and that was all. Making the Superduct was flattering to me and I think this came about due to my then problems of supply. He later developed the bigger mouth to replace the stock item. He does continue to develop great products for the BMW range and the R1200S race bike is looking really good.
Carbon Fibre was not a consious choice but one recommended due to the heat from the cylinder and head. Material cost to my supplier is only about $30.00 more expensive than fibreglass. The labour cost and autclaving is where the major cost is at.
Deciding to use retailers in the UK and USA was more about having a local presence than anything else. MotorWorks did a great job in the UK and CBT Imports in the USA.
While CBT were selling the InDucts, Mark Doebeck formerly of DynoJet fame fitted a manometer to an R1150Rt with an InDuct. At 18 miles per hour the manometer started to read and at 100 mph it pegged the guage at maximum of 4 inches.
The product works and the combination of parts developed were only ever to put more smiles per mile on the owners of these great bikes.
I have GS owneers now fitting the advanced timing cam sprockets and surprising to me they actually work very good.
Good to see there is a great BMW community in the UK and I have a brother in Abingdon who has given thoughts to buying a BMW. If he does I will point him this way.
Cheers all and thanks ofr the interest.
I have another board now to take some interest in.
Regards,
Lennie
