Does this not sound absolutely amazing?

The other day we were all having a conversation on discord about the sounds of various cars, and then of course someone brought up a supercharged mustang, which I think is cheating a little, the charger makes all the noise with no real boost curve. Well, I decided to go out and record the sound of mine, from inside the cabin. I've had a few friends describe it in different ways, but I want to know your thoughts. There are no superchargers on my car, but there are 3 modified turbochargers, and a heavily modified engine. Before you get your panties up in a knot about doing this on public streets, it was a 50% throttle run, 1st and 2nd gear only, at 1AM, and I cut it just over 60mph.

Sounds awesome.

If I'm not mistaken, the whistling sound Is the result of the turbos kicking In. It'll be Interesting to see what It does In a quarter mile. Back In my younger days, my friend's Monaro (350 Chev modded to the max), 4k high stall auto, 4.11 diff ratio pulled 11 seconds flat. Given It was a pretty heavy vehicle, It was quite quick.

If you listen closely you'll hear 2 different pitch classes, the less significant one is the first 2 turbos, the really loud one is the much larger third one, but its not the turbine blades you hear, its the volume of air being sucked through it.

It's been a very long time since I've heard of someone putting a high stall TC on their car, that's one of those things that sort of stayed in the retro era along with decent engines.

Now that I've listened to It carefully, I see what you mean with the turbo.

With the high stall, that was close to 30 years ago, They were widely used, so too was the good old B&M shifter and the Mallory tachos (tachometer). I haven't touched motors since then, so I don't know whether "roller rockers" are used nowadays, but they were popular back then as well. Powerglide transmissions were somewhat popular too.

Those were the days... A lot of that technology has been lost to the digital era, but high stalls are still used from time to time.

Yes, I'll never forget those days.

Attending the drags (drag racing) twice a week, see who can get the quickest time In quarter mile, applying VHT on tires for traction and the list goes on.

I'm a huge sucker for good sounding NA cars, but I can dig it. Is this the bimmer?

$4,800 car
$4,000 engine
a few grand with the little bits that i needed to make it all line up
and about 2 years worth of fixing problems
