Updated external wastegate

Thought I'd show a picture of the updated external wastegate. Hopefully Dyno this weekend.

Nice.

It looks good, but I wonder how it will keep from cracking over the long run? WG tube has a ton of thermal expansion, so without a slip joint it could crack just above the weld.
I'm sure you know that. It could last 50k miles or 3k miles. |

Normally I would be concerned with the lack of a slip joint also however the distance from the exhaust ports and the direct exposure to under car airflow reduces the thermal energy this system will see greatly. I do not for see any real probability of failure here, yes there is expansion due to thermal expansion , but I doubt that assembly will experience enough to stress the material in less than 50-70k miles, unless the OP decides he wants to run the turbo to the ragged edge... I would have used a detached wastegate with it's own muffler assembly venting to the other exhaust outlet but he never asked me lol |

I did think about running it over to the other side with its own muffler etc. But decided to keep it close and light, no need for extra weight in this car. We will see how it goes, if I get any cracks I will do a redesign for it. I'm not to worried as I have a full machine shop and a hoist in my garage for any mods needed. |
John Visconti was in town this week and we got together to do some tuning on the car. Wow, what a difference after John was able to do the car in person. John is a very dedicated and meticulous tuner, top notch in my book.
