PROJECT - TOP SECRET - Engine updates, Everything about my engine Options

Hey,

This weekend finally i had time (and my friend too) to work on my custom turbo Header. We started like 11.30 am, and both thought that this job will be easy... Yup, it wasnt... All thought about the design, everything that we where doing seemed wrong, and like spending WHOLE DAY just thinking how it has to be, BAM we finally worked somthing out. I wanted that piped of the header where as much equal as they could be. So, i hade to move my radiator in fron a bit, to have more place for my turbo. Anyway, pics say more that any word, so here ya go:

Well I dont mean to bash but there are 2 things that I wanted to ask before you run this thing first is the what is the exhaust size of the turbo that you are going to run also what kinda Hp. are you looking to make? Because thermal expansion can fracture the header bolts so over size those also the flang can warp under high temp. this will break welds cutting the flang will help with this problem.. this is for high Hp. apps.
Smooth, constant velocity is what you want
I do have one other question what is the thickness of your tubeing it could be a problem.
As for the down pipe figure 10% larger than turbine outlet diameter. also when you weld the down pipe flange weld in 1/2" increments that will help. I hope that helps you out
