What causes race cars to make a "chirping" type noise?
Jul 07, 2008 by Hill | Posted in Maintenance & Repairs
I recently started going back to the (drag) race track and noticed that sometimes when cars come to the burn out box you can hear this "chirping" sound. It doesn't sound bad, but I'm just curious as to why they make the noise. To be more specific,
It's one of two things:
I would think it would be caused by a turbocharged engine's blow-off valve. When an engine goes from high boost to its fuel cut-off (or when the throttle is quickly let off), the access air pressure is released

JEFF GORDON, NO. 24 DUPONT/NATIONAL GUARD JOB SKILLS CHEVROLET met with media and discussed racing at Michigan, driver rivalries, NASCAR R&D meeting, and more.
ON RACING AT MICHIGAN
“I love coming to Michigan. As good as our team and our cars have been this year, it’s definitely a track that’s a highlight on our list of tracks that we’re looking forward to coming to and things went really well (in practice) today. Of course the rain shortened it and we only got a couple of qualifying runs in, but still feel really good about today as well as the weekend.”
ON JOEY LOGANO, DOES HE RACE YOU HARDER THAN HE SHOULD OR JUST NOT GIVING RESPECT TO HIS ELDERS, OR IS THIS JUST THAT THE VETERANS DON’T LIKE THE NEW KID COMING IN?
“I haven’t had any issues with Joey. I feel like when he’s competitive he’s aggressive and does what he needs to do and when he’s not, he’s respectful. It seems like he’s always respectful. So I’ve had no issues with Joey. He and I have raced one another hard and clean and if I felt like he was ever out of line, I feel like it was justified (laughs).”
DID YOU GO TO THE R&D MEETINGS WITH NASCAR THIS WEEK? CAN YOU TALK ABOUT THAT?
“I just like the trend that they’re setting and I think that’s the direction I think they’re going in and I think they saw a lot of value in going about those meetings and trying to get as much input from the teams, car owners, and drivers; and crew chiefs, if they’re not in those meetings, there are other meetings with them that they’re getting information from as well. It’s good business. It’s valuable for everybody to see where their thought process is currently and where the sport is. They’ve got a lot of data that none of us, or at least from a driver’s standpoint, have the access to. So updating us on where the sport is at and what kind of feedback they’re getting from the fans and from the media, and so it’s good to get updated as well as having open conversation about some ideas that they have coming along in the future. What’s nice about it is you feel like you’re in a forum where you can be open and honest and tell them what you really feel about it and that it doesn’t go any further than that, and let them continue to make their decisions based on gathering that information. So I think it’s just another way to gather information from as many drivers and car owners and crew chiefs as they possibly can. I’m a big fan of it. It doesn’t mean I always like what I hear in those meetings. There’s always a bit of a surprise that comes to you and you don’t know where they’re going to go with that and whether it gets implemented or not. They’re certainly thinking about a lot of things. Some are in the box and some are outside the box. That’s, in my opinion, what you want them to be doing.”
