Bauhaus, buddy . . . Form follows function.

A bigass garage, a Butler building, a small ranch, two hours out of Tulsa for the Annual Bob Wills Birthday celebration every March at Cain's Ballroom.

Boy, Howdy!

It's a non-starter for me if I gotta wear cowboy boots and a cowboy hat.

Can't give up my New Balance Cross Trainers . . . . . .

And I don't wear hats, well, except fur lined ones, in WINTER!!

Mark, never owned or worn a cowboy hat in my life.... not a hat person either... that was an issue during my 9 years in the USAF.... they are a hat wearing organization  undecided

Have owned boots other than those issued by the previously mentioned organization... but no cockroach killers...

If you don't require big city living, affordable places are available in the less populated states.  Kansas does not tax your social security income.... unlike the feds

Note to BMC fans . . . . . . British and otherwise . . . . . . . .

One of the pre "Runoffs" projects is a limited prep BMC 1275.    The flow testing is done, the dyno testing will take place this week.

As soon as the project is completed, I'm going to post some real world numbers for Limited Prep heads Vs full race Vs Stock air flow.

I'm also going to post some comparison graphs of of the dyno output Vs the Grenade Vs F/prod 1275's Vs unrestricted 1275 GT/L engines.

Should be . . . . . . interesting.    And it will get us through the 'K' development lull . . . . . . . .

I have a few ideas for the LP stuff, but it would take some $$ to pull off. Camshaft development seems to be the most lacking.


Re:    BMC 1275 Limited Prep

20+ pulls later, this is what I know for certain . . . . . . . .

A/   Compression Ratio limitation (11 to 1) dramatically affects spark plug choice which affects the total ignition timing required . . . . . .  NO big surprises here though.

2/   The valve lift limitation (.450" measured at the valve) also dramatically reduces power output.   The test engine was relatively "insensitive" to valve lash changes, indicating that there was not enough "cam" for "good output".    Cam was a billet Bachmann item.    I was told several competitors use it.    It's really hard to conclude anything yet, no thorough cam profile data so far.   The cam data presented was basic and minimal.

Bob, there is NO question in my mind that you are correct in thinking that the cam development could lead to further gains.    If I get an opportunity to "spin the cam grind for data", be assured I will.

d/   The requirement to utilize the "stock" 1.25" SU's, "un-modified" is a "gigantic" air restriction.   Significant gains could be made with trick "Blue-printed" carbs.    There is currently a "snipe hunt" underway for factory specifications.    As it stands, there is a nice bhp output curve up to a certain rpm, the the bhp goes essentially "flat".    That usually indicates restricted airflow into the engine.    ANY "trick modification" would need to fall within measurable factory dimensions.    The carbs used were "blue-printed" Bachmann items, which worked well.     I'm just left wondering how much the rules can be "pushed" for this area.    Even more reason to do some flow testing of 1.25" SU's . . . . . . . . .

z/    Cylinder heads that flow "too much" are a waste of time and energy here.    Think about it, the main restrictions are the carbs and manifold.    Too big ports kill velocity and flow and  . . . . .  wait for it . . . . . . transitional bhp.     


I have not downloaded the "data dump" yet from the T&T dyno computer, so I have not done any serious number crunching.    But, from memory, peak TQ was 87#/ft to 90#/ft.

That translates to:   87#/ft = 164.2 psi bmep
                              90#/ft = 169.9 psi bmep      Both sets of the bmep numbers are on the low side, indicating that careful development would raise output.

That's all for now.   More in a few days . . . . . . . .

 cheers

Think about that a minute -

A 60 year old chassis design with a 65 year old engine design, giving Honda Fits fits.

Hail, Britannia . . .

Well, to be fair, the chassis for all these MGs is 'full prep'. So other than the stock upright and stock live rear axle, anything goes as long as it's not a pushrod type suspension. These are modern clean sheet racing suspensions. The Hondas and the other "late models" (that are as old as me) have to use the stock chassis with just a change of shocks, springs, and sway bars.

Also, these MGs weigh hundreds (in some cases 500-700lbs) lighter, per rules, than the cars they are competing against. Weight helps make up for A LOT Wink

Wills really made his name and career in Tulsa and Los Angeles.

I think everybody should go to Texas once in their life, and judge for themselves.

To find Texas from where I live you go east till you smell it and then south till you step in it.

I made it back . . .

I've been to Texas a few times.   The steaks are always good.   The building code non-existent.   The snakes/scorpions/spiders are plentiful.   Much is oversize, (think Texas Stadium . . .) including the egos . . . . . 

JMO, but I think drive through bars are a poor idea . . . . . .  OR, the personal right, to be naturally selected, out of the gene pool . . . . . . .

I survived all my Texas experiences, some pleasant, some not.


I also am unsure about where we are going to "land" in "retirement".   Probably going to stay close to where the majority of our kids live.   So NE IL for now, just south of the "cheddar curtain" . . . . . .
