Fairmont Suggestions

[EricTheCarGuy]

I have some plans of my own but they say that the more the merrier. I’m opening this thread to see what some of YOUR ideas are for the car. If nothing else it will be nice to see how you, the fans of the project, think.

I came across something today that I thought was interesting. People are using wastegates as boost referenced exhaust cutouts and there are some dedicated cutouts made for this. https://www.youtube.com/watch?v=m5gaAuGNk5M Any thoughts?

Hmmm… interesting, not exactly a new idea, but still interesting.

Pontiac had an option on the 1970 GTO’s that was known as “VOE” (vacuum operated exhaust.) As I understand it, it was basically a set of move-able baffles inside the mufflers that operated on demand via engine vacuum. It was only available in 1970 and was only available for a short time due to goofs in the marketing department- https://youtu.be/7JNj9sEdPF0

I’ve started seeing aftermarket mufflers like that on the market in the last few years. But if it was me, I wouldn’t worrying about any sort of silliness like that video shows on the Fairmont. Either have an “ON/OFF” loud switch for the exhaust or if you want to get really scientifical about it, research/figure out a way to have the cut-outs open up when you want them to when the loud switch is in, say “RACE” mode if you’re worried about back-pressure vs. flow, turbo-lag, etc.
