Tried to make my car sound like a machine gun under boost.....ACCOMPLISHED


Changed my plugs out and refitted the IC. Took for a drive, tested my antilag I just fixed (switch broke), and then decided to lay into it in 3rd.

Boost came on like normal, then the engine sounded like multiple machine guns going off at once.

WTH! I quickly let off. It then dawned on me that the one thing I forgot to hook up was my wastegate signal hose!

Holy crap!

I've asked before many times what detonation sounds like in an air-cooled motor. Always wondered if it sounded different coming from thin-walled cylinders vs coolant jackets. I no longer need to ask. I know now.


She seems to run fine, cruised her back home and hooked up the line.

I looked at my tuning software and thought, "maybe I should have turned on the overboost protection?!?!"

Lesson learned.......

Hopefully nothing long term like a broken ring (or two) or beat up rod bearings. We will see.
