That other MM - what a sweetheart!

True about the essential demise of Spridgets in SCCA.  I went to the June Sprints in 2009, camera in hand, in an attempt to get some decent detail photos of how Spridgets are typically caged.  300 cars gridded that weekend - one Midget and an MGA.

There were more Corvairs than MGs.

Midget,

Seems right to me!!   Well, as long as you don't want to stop or slow down. . . . .   (Yenko Stingers have 4 wheel drum brakes, how quaint. . . .)

Preliminary Dyno prep checklist attached as PDF.   Please review and send additions, suggestions, changes, etc, etc.   There are always some. . . .

Chris, I'm back from my excursion to the land of tequila powered calendar makers, so if you need manpower, let me know.

We really should do McBobs.

My latest column is up - some observations on the British car community.  Some say it's dying - I say it ain't.

Midget,

Insightful column, as usual.   Of course the breed isn't dying, dyno adaptors are still being made. . . . .

Wheezing from lack of airflow, maybe. . . . .

Don - Yes to McBobs, but I'm insisting on either before or after the Leprechauns have made their pilgrimage on the 17th - I try to avoid amateur night in Celtic drinking establishments.  It's a self preservation strategy. 

Actually, let me know when the next Brew City Road and Track Timing Association Flying Circus meeting occurs - I owe Dick Luening a couple of beers.  He came through for me today with an MGB flywheel, which is on its way to Fordboy, who will draw up the print for the drive hub for both a 1275 and a 1.8.  That way, come the time I rebuild/build up the MGB engine, I'll be one step closer to dialing it in on the dyno. 

Geo - the magazine has arrived - brilliant!  Thanks a ton for that.

PJ, thanks for the kudos - it's been a good discipline staying on top of a pseudo-monthly column.

Fordboy - okay, got the sheet.  That tentatively looks like an aggressive schedule, but we'll make it happen, and I'll begin preparations tonight.

New Years and the 17th, both amateur nights.

Midget,

Yes dyno day looks aggressive, but it will just depend on how many gremlins we encounter.   Hopefully, none.

Once the cam is run-in and the valve springs are changed, etc, things like jet/emulsion tube/ignition timing changes tend to go pretty quickly.   Unless the carb is a total can of worms, and it should not be, I want to be realistic and conservative.   We are not inventing the wheel here. . . . .

Regarding the pre-dyno session checklist:  There is still lots to do, all on a self-determined schedule.   Once all the adaptors/linkages/bits are finished & trial fitted, is the time to book the dyno session.   All that will remain to do is to gather any supplies, tools & headers.

Hey, how about a pic of the jewel with the adaptor plate bolted to its' a**?

So you want to have an engine/dyno shop in your golden years??   I'll ask you again after the dyno session. . . . . .

I think I want to be a Cicerone when I grow up. . . . . . .

I'd like to get this thing on the salt before then . . . . .

After following this build diary, I believe Chris has already accomplished that.

If anyone is in Wichita for my Birthday one of the local Breweries has 5 stouts they are debuting, at least 3 maybe 4 are barrel aged, at least one on nitro.  Had a couple of nice porters aged in a Bulleit  Rye and Bourbon barrels for their anniversary last Saturday.  After lunch today we stopped by to see if anything was left... still had the Rye aged porter, still yummy.
back to business
Nice article Chris
Wow, you do have a lot to do before dyno day....

Midget,

I want to calculate the torque peak based on header pipe diameter, prior to your selecting possibilities for dyno trial.

For the current car header set & other headers that you have, what I need to get started:

1/   Primary pipe O.D.  &  wall thickness/gauge
2/   Primary pipe centerline length, approximation OK
For attached collectors:
3/   Collector pipe O.D. & wall thickness/gauge
4/   Collector pipe centerline length, approximation OK

I already have the data from the other pipes from Mini Maven.

BTW: I'm predicting your ultra-long rod will pull the torque peak & bhp peak closer together. . . . . .    It will be interesting to see how close the results will match-up. . . . .

Dude – you’re kidding me.  You couldn’t have asked me this before I took a shower? 

An hour ago, I was out in the garage mocking up the aforementioned headers and an alternate intake manifold. 
 
I feel like a census taker for William the Conqueror.  “The Doomsday Book” gets thicker and thicker. 

Bloody Normans and their databases . . .



Okay – the dyno adapter – all the bolts line up – the only exception being the one that interferes with the starter.  This attaches to the bellhousing of the dyno, so either a shorter cap screw is in order or perhaps a stack of washers.  The dyno we’re using has a starter, so I need not clearance the adapter -




This is the header I originally bought.  It’s a Peco, pretty much a cheapo street unit, 3-into-1.  It fits, it doesn’t leak, and this will be our starting point on Dyno Day -



The intake is a short Maniflow unit I picked up off of E-bay a while back.  The flanges are larger than the longer TWM manifold I’ve been using, so if the header flanges clear this, they’ll clear the TWM.  Will we use it?     Maybe?



This is the LCB header – “Long Center Branch” - that my buddy Matt Meixner is loaning me.  If you will note, it has no collector – it was introduced and reintroduced to the tarmac at Road America on the Carousel and Canada Corner repeatedly and therefore is in need of a weld up.  So once I have the primary pipe lengths, the diameter, the gauge, the primary pipe centerline lengths, the impending Pontiff’s hat size, a pony and tickets to see Van Halen, we can make it any length we want.  In short, I have no idea what length it originally was, or the diameter.  I’ll get you the numbers, and maybe the Pipemax program can ferret out a suggestion.

Capital Maibock tonight - leftovers from my sisters this last weekend.

Meah . . . it's wet.

Stainless - thanks for that.  Enjoy your birthday.  Your stature is clearly higher then mine if your local brewery creates 5 beers in your honor.

Chris... everybody parties on my birthday... R. W. Patrick Steele.... 5 new stouts is not really overkill for a regular customer....

The LSR B & B is available for most dates.... we have an opening for 2 almost always... forum members should PM or call for availability

Midget,

Hey!  Did I say jump?  Or right now?      Calm down, when you get a chance is fine.   I understand showers, beverage consumption and self-imposed deadlines.    AND, believe me, I DON'T WANT TO KNOW WHAT YOU DO IN THE SHOWER!!!!

Ahem,   thanks for the assembly pics.     Pre-dyno porn for all the voyeuristic racers following along.

Not one drop of Norman blood. . . .       hence, I prefer to think of myself as a "planner". . . .   though I am partial to databases. . . . .

"I love it when a plan comes together."   Col. J. (Hannibal) Smith        Me too. . . .

Sorry, no suds review from last night.

Midget,

MGBeater flywheel just arrived via UPS.   I had to interrupt my spreadsheet & database spell casting to answer the door. . . . . . .
