Can we officially address the Myths on the TB forum (w primary sources)

I’ve never heard a redblock that didn’t sound like an early 80’s Mercedes 300d

none of my current redblock turbo cars have any noticeable piston slap or sound like a diesel. I have owned many non squirter pre 90- that did in the past though

I have owned more than 200 redblock powered cars. A few of the early B21 powered cars were quiet. Only one B230FT in an 87 740 Turbo was quiet. 270K+ miles on that engine. No history on the car. It could have been rebuilt for all I know. Not a single B230 squirter engine out of those had piston slap. Some of them were so quiet it was hard to tell they were running with the hood closed. There is zero doubt that the squirters are a major benefit to the longevity of a redblock engine.

Not as cool but they are better cars.

The 9 series are modern cars in ways that a 2 just can't be. I love my 240s, but as a daily, the 940 is just better.

Absolutely. My only gripe is the 7/9 seating position sucks with it being so high relative to the steering wheel. The 240 is superior in driver sesting position for me.

Edit: another myth:

B230F is not 9.8:1, it's closer to 9.1:1. Source: me since I have measured all of this. Chambers are 54-54.5cc. Pistons have 8cc of dish. Pistons are oftentimes .004" above the the deck. Head gasket hole is 97-98mm. Elring says the compressed thickness of the gasket is .047".

B230FT is around 8.3:1.

I agree with these numbers.

Additionally, dish on a B230FT piston is 16cc.

If you are driving 7/9 you better not think what others are thinking. I haven't met a single person who thinks that 31 year old 945 is a sensible choice as a DD.
