I don't get why it should take a company so long to make a "kit" if the blower is already designed...
If you are using a separate ems surely it is just a brackets to hold the blower and any other bits like inter cooler and some pulleys or am I missing something?

What is to stop me going and buying a blower and getting a shop to fab me some brackets? Presumably it is just tricky to get everything lined up...?

I take it I am missing something or everyone would be doing it!

Carb cert is irrelevant for me BTW.

 

I'm guessing it's the testing of the individual parts and how they work together that takes the longest. It wouldn't be a problem if you were just copying an existing kit, say comptech or vortech as the work's already been done.

Then again, (at least for the mechanical bits) it really is a question of making some brackets, lining everything up and making sure everything's strong enough not to crack etc....

 

a "kit" is all about R&D

This fits with a,b,c and you have to do x,y,z

if you make your own "kit" it could turn into you have to do this to a, that to b, and the other thing to c, and you still have to do x,y,z to make it all fit....

As stated above though, there is nothing to say you couldnt copy an exsisting kit if you can piece it together for less...

 

The early Comptech units had problems with the brackets breaking. Of course you can do it yourself, but you will be doing your own R&D and there is a chance (the odds depending on how good you are at mechanical and structural engineering) that you'll run into a long series of small problems that will end up costing you more than it would have cost to buy a proven kit in the first place.

That said, I'll post a link to the DIY turbo kit a friend of mine did on his Benz E320. His DIY job worked the first time and has yet to require any changes to meet his needs, so such things do happen.
