    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

TSCC = Typical Suzuki Clobbers the Competition

Fine example of a passive performance enhancer. Can't help but compare with the Yamaha YPVS but that came with complexity.
Seems like that in the 80's there was a lot to be gained with 'simple' ideas and almost every model year had something.
And what kind of surface is that they are testing on........... 3:50 onward.
 
Funny thing about TSCC is technically there's no swirl... The inlet charge motion is technically 'tumble'. Swirl is around the axis of the bore and generated in 2-valvers by offsetting the inlet tract to cylinder. Tumble is on the same axis as the crank and was pioneered by Ken Duckworth of Cosworth in the four valve DFV F1 engines. The tumble energy is converted to high turbulence by squish bands in the head, speeding up combustion burn rate and making more power.

TTCC. Twin Tumble Combustion Chamber... If only Kiwi had been working for Suzuki back in 1979.
 
I'm not an engine designer, but I wonder if terms like "tumble" and "swirl" were defined by the engineering community back in 1980? Engine design was evolving quickly at that time, particularly in terms of making low emissions engines.

Probably, by Ricardo.
Every good idea was Ricardo's first, or so it seemed at the time.
I discovered that at first hand. Every time I thought I'd came up with something new I found Harry Ricardo had been there, long before.
