What's the whistling sound I'm hearing at the top of the rev range, windows up?

Full throttle, top of the rev range. ~60mph

Turbos or is it just wind noise?

The whistle is the turbo. You may also hear a little chirp when you quickly let off the gas. That is the extra boost being released. Both sounds are much louder with intake. Thx for the email, bryan.

I guess you run into douchebaggery when you're 3 years late to the 335 game? haha.

I know. Didn't think the small stock turbos would be that noticeable.

Good times.
