Turbo flange

[justin ivan]

Corky Bell's book maximum boost has the formula that he recomends for 
enlarging the holes. I can't remember it off the top of my head and am away 
on business right now otherwise I would post it. I do remeber that I was 
shocked at how much he recomended enlarging the holes, it was pretty 
significant (I want to say 1/3 of the diameter of the hole). Slicing the 
flange after you weld the piping is also a good idea. I have a question 
regarding turbo header construction, has anyone found an elegant solution on 
how to merge the piping together. Need somethine like an NA header collector 
but it needs to be much shorter to ba able to mount the turbo in the engine 
bay.
