Motorcycle Repair: Turbocharger or Supercharger Available, harley engines, supercharge kits

Question
Johnny, I have a 2003 Sportster with an 883 engine, I was wondering if you have ever put a turbo or supercharger on any Harley engines, if so how well did it perform afterwards.
I don't know if there is anything like that available for Harley engines or not but I figure you would know if anybody did.
You helped me with a problem I had with this bike when it was new and I posted a message to you letting you know that your answer to me solved the problem but I don't know if you ever got the message.
Thanks
David

Answer
there is a kit from Arrowcharger. But turbos and superchargers  are very expensive, a Axtell 88 inch kit is as good as any turbo and is half the price. I do not know of any supercharge kits. I have done turbos and superchargers and found the turbo to work the best for the money. I installed a 88 inch kit from Axtell on my 883 to make it 1450cc and it made 121 horse power at the rear wheel with good STD heads. and is trouble free.  Johnny
