Honking Noise Sometimes from Engine Area?

[imolas54]

I believe this is a sign of the diverter valve going back, but just want to confirm:

This happens mid RPM range about 60-70% throttle, doesn't happen at WOT or between shifts.... Any ideas?

Thanks

yes, your assessment of the honking might be right....my first guess would be diverter valves. Your choices for the most popular replacements are Bailey, Forge, EVOM, and I may have left someone out. Everyone has their own favorites. I went with the EVO's because I got a good deal on them....most of the better replacement OEM types can be taken apart, cleaned, and lubed up for periodic service.

What mods are on the car?

Definitely check the diverter valves, especially if they're stock.
