Intercooler air horn

[Sparky dave]

Hi guys just thought I'd share this with you, I know the pic will be confusing but bear with me I'll explain.
I'm currently in Thailand and today I hitched a ride on a long tail river boat. They use truck turbo Diesel engines and gearboxes, fix a long output shaft out of the back and stuck a propeller on the end. It's all home made. And to top it off they boost them up to the high heavens! They go like stink!

So anyway this next bit might be of interest to diesel guys. The guy had a super loud air horn which I'm sure was piped into the intercooler pipe ( has anyone heard of this) which got me thinking could you not slowly bleed off intercooler pressure and using a pressure regulator fill your air suspension tanks also. It's just an idea ( maybe it's been done, maybe it's a bad idea or maybe it can be the start of something )
Anyway just some inspiration from the other side of the world to share with you guys, peace!
