Turbo Bracing

I thought I would start this since I see it ever few weeks on all forums SQ. People offering manifolds prior to us were adamant about "bracing the turbo" The issues is they were just doing it wrong. That has lead to bad information being regulated by most of the SQ community.

 

1. A brace is needed when using thin wall normal exhaust tubing 16 gauge

2. Thin wall exhaust tubing has been used on 100% race applications where every pound saved matters

3. Thick wall/Schedule 40 pipe is used for street/track applications as it can handle the weight and street use as well as constant heat cycles seen by street cars

4. If you want to run a thin wall turbo manifold you must brace the turbo and the wastegate as the weight of the two will easily crack the thin wall

5. You do not brace the manifold/header as its been done before

6. Bracing the manifold does not allow for expansion

7. Manifolds expand and contract with heat cycles

8. The combination of weight and the manifold being braced doesnt allow for that expansion

9. Doing so causes the weakest part to give

 

You all know how its been before but here are some photos of braces done properly.

Here is a shot of Schedule 40 next to 16 gauges stainless so you get the idea of different sizes

Ronnie, I am so glad you decided to join this community and share the information you have learned in your daily professional life with us. You echo some of the thoughts I have had for years, but I didn't have the background or resources to be able to convey them so well. Thanks for what you have done and continue to do.
