Seal em up… – three enginneers joke

Have you heard a joke about land rover engineer… if not, here is the story…

========= There are three engineers from different companies in a bar… one from land rover Solihul, one from Mercedez Benz Germany and another one from Toyota Japan…. you know when three engineers meet up, they will try to out boast each other how their brand is better than the others… and it seems they have a deadlock, no one can convince each other. so they will put a very scientific test to the car… it called “a cat test”.

Basically they will put a virgin cat inside the car (so if the the cat died it has no kitten suffering), and then they will comeback 6 months later with the doctor to do autopsy to find out what happened with the cat… So they put the cat in Mercedes G, Toyota land cruiser and Land Rover Series III, all brand new… they left and agree to meet again 6 months later same time. Cut the story short, 6 months later the three engineers meet up to see the result, and they bring a long the doctor…

First visit is the Mercedez Benz car… they found cat body (or the left of it) in the car and the doctor do the autopsy… the result : The cat died by way of suffocation, estimated death 2 days after the cat put inside the car…

Second visit is the the Toyota, and they found the cat body (or the left of it) and do similar autopsy… The result : The cat died by way of starvation, estimated death 2 weeks after the cat put inside the car…

Third visit is to the land rover… but they can not find the dead body…. they found a cat and three kitten instead…! =========

Can you imagine, if the cat can gets in and out and breed as she please in a land rover series, how about dirts, winds, water, stone, mud etc… they all can get in easily… the one will not get in is Missus or non land rover fan friends :) that bring to my subject as in the title.. we can actually seal them to a degree where it can slightly weather proof…

First: Drive them in the heavy rain and mark where it leaks water or dirt etc… in my case the water leaks from the front where the wind screen attached to the bulk head… put the mask tape for cleaner and tidy result and then use the the sealer (silicone) gun to seal them up.. job done… time needed 30 minute to 1 hour, cost US$ 5.

Carburetor SU HS6 Set up for Land rover series Part 2

Please read part I here…

This part two is about the selection of needle and spring. When you setting up SU carb for Land rover series, you will have thousand of options to decide which needle and which spring to use…

Why Needle and spring..? because the needle and spring will dictate the attitude of the car, The SU carb is very simple vacuum type carburettor, which can be considered as their strength, needle and spring selection to match with our engine is a very important step and it is very confusing…

Fortunately there are brave hearts that already convert their old Zenith carb, to the similarly old SU carburetor with varying degree of success… some are using dyno / rolling road to measure the result, some will just use what ever they got on the carburettor and hope for the best. Alternatively you can buy software to select the needle but it beyond the scope of the article

From what I have read, and research… they are few needles candidate to be a good match for land rover series here they are:

BGB needle: this needle used by ACR for their (very expensive) conversion, the BGB needle paired with black spring.

Since they do it to make money for their conversion, I believe they do a lot of (proper) test to come up with this pair. So… it should be the best pair for our land rover series correct..? Yes and may be No. The ACR is offering this conversion together with the performance head, performance camshaft and performance exhaust, so I think that work best on using their set up.

Unfortunately no one (not that I am aware of) is actually using SU HS6 with Black spring and BGB needle on the stock engine. Theoretically BGB needle will be too rich for stock engine.

BDM Needle: this is much leaner needle than BGB, but one land rover forum friend using BDM and red spring set up wich he can describe as working good.

Another candidates are “BBW”, “BDB” few forum lister using it but I am not sure what spring they use but what I have read they have some success using them…

What about my Set up..? well, since I have no money to do a proper research.. so I have to make do with what ever comes with the Carburetor… which is “BAK” with a green spring.

Just to give you the idea the difference for each of the needle candidate, below is chart showing the diameter profile for each needle, before that this is how to read the needle profile:

if we give them number from the top (as position number 1) and to the bottom ( position number 16), you will see the diameter for position number 1 and 2 is for idling, from 3-6 is cruising and from 6 above is revving…

Now lets see the needle profile of all our candidates, see below chart, (if it is too small just click it on the picture). Vertical axis is the diameter of the needle, the higher the smaller the diameter ( means richer fuel), the horisontal axis is the position on the needle

As above you can see, BGB that the ACR used, is the richest of all… BBW comes second so I think BBW can be used for slightly economical than BGB, and number three is my current set up “BAK” needle.

you will also see that the first in position 1-4 the diameter is almost the same for all needles, means that idling and some cruising is almost the same for all needle. the real difference will be after position 4 where some is significantly richer than the others.

Spring: other than needle there are few selection of springs but not as many as needle… Softer spring will easily lift the piston fast, providing more air flow, the stiffer spring will resist of the upward movement providing more fuel enrichment, the idea is to have top maximum carburetor piston lift when the engine is in the top /peak power :

Code	Force in Oz.	@ Height
Blue	2 1/2	2 5/8″
Red	4 1/2	2 5/8″
Yellow	8	2 3/4″
Green	12	3″
Red & Green	11 1/4	3 7/8″

As above mentioned, from the land rover forum I got confirmation that “BDM” (relatively leaner) needle with Red spring (relatively weak spring) is working sweet. using this as benchmark, my set up : “BAK” (richer than “BDM”) will work OK using green spring (stiffer than red).

I know I am over simplify things but my set up seems OK now… only rolling road will show whether this set up is optimal or not… I will not give you any suggestion on what set up to use, but you can use the above set up as starting point… I am not the expert, I just taking what I learn and share it

That’s it for now, until then… take care my aluminum junkies friends… :)

Her name is Dolly…

Finally I join the land rover owner stupid habit, naming their vehicle as it was a person… There is actually a name for this habit, its called

Pathetic fallacy : ascribes human, emotional qualities (feelings, thought, sensation) to inanimate objects, as if possessed of human awareness. In describing and ascribing sentience to things, in the term pathetic fallacy, the word pathetic communicates feelings of two types, pathos (emotion) and empathy (capability of emotion).

Although sound pathetic, looks pathetic, and probably indeed pathetic, I will do it anyway :). After few months without name, I finally found a name for it… but before that I will tell you my other options. One thing that we need to remember when naming a landy (or any car) appropriately: the car gender is female… Not sure why but this is European way of thinking, (may be because we “ride” her), since landy is England origin, I just follow the suit…

Option 1. Actually I am thinking of Indonesian Names : like Rina, Siska, Dewi, Santi but somehow it is all the name that the missus would not approve, and if I ever mumbling any of those names during my sleep, I will be in deep deep trouble.. :)

Option 2. Still Indonesian name but animal: Bleduk (anak gajah), kuya, gudel (anak kerbau), genjik (anak celeng) etc… but it all seems bit off

Finally finally, I found a name which probably suitable for it… Dolly… after Dolly Parton, she was born in 1946 and her prime time was in 70s… She was a country singer and quite good at that… but sometime she just (playing in Best Little Whorehouse in Texas as a) bitch… She never be a porn star though and most (if not all) of the nude picture of her are fake…

So.. country music, busty, sexy (by 1970 standard), sometime bitchy… just the way I like it… thats my landy and riding her will never be the same anymore… yiihaa… :D

One of Dolly Parton Song below….

First try – portrait…

Nindy – Kodak Portra 400, carl zeiss sonnar 50 f/1.5

First try of classic portrait

I shoot film..!

I love photography, but that does not mean that I am good at it.. :) I can not sing, can not draw can not dance… it seems that I have very little sense of art. So, I kind of give up… but how can you give up something that you love…. you just can not.. ha.. !

Here I am still continue taking pictures… Sorry if it doesn’t up to your taste, but I don’t care.. :D. This time is different though… I took pictures using manual film camera. Somehow Land rover series and film camera is just a good pair, love them both… and here you go… my first try

1-000037 — Kawasan merokok : Kodak Portra 400- cropping only

Out of 36 film, I shot 6 of them with the cap on, yes it will be very easy to shoot range finder camera with the cap on… you can not see the difference. so wasted 6 shots… since I am using camera TTL meterin, only one of them is too dark.. others are mostly bit overexposed…

Second try… kids picture… seems good idea..

Kodak Portra 400 – Simple picts but not easy to take, I know this kid will be coming out of the house so I pre-focus and wait.. when He came out, he looked at me and I snapped the pict before he knows what happened… so much work for simple picture :)

Now how about taking picture of people smiling or laughing… man, that is not easy to make someone laughing while you point the camera to them… Here is my try..

Same joke different person… :)

Kodak portra 400 - I will not tell you the joke... the feminist will kill me.. :) — Kodak portra 400 – I will not tell you the joke… the feminist will kill me.. :)

Ok thats it for now.. please do not stating the obvious that I take a crappy pictures… if you can tell me how I can become Steve Mccurry please write down below.. :)

Retiring the tires

Hey its Rhyme… :), I changed the tire the other day as the tire is too old and bald… its long over due tire change I might say, because I can see small cracks in the rubber. The question is: which tire… Actually not much choices if you use stock rim. In Indonesia the most use tire for stock rim is X-tra grip from GoodYear, a long lasting tire, ok light off-road, but road usage is not ideal.. here is the thread pattern of the tire:

Some tips when changing tire:

Ideally if you can change all four then change all of them… or 5 of them including the spare tire
If you can not change all of them change two tires is minimum, never change only one unless absolute necessary…
Put the new tires at the front, because the front tire will get bigger force when you braking… if you put old tires at front, the braking will not be optimum
Do not use the tubeless tire on the stock rim, it designed for tubed tire… Some will say you can, but I suggest not…
The equivalent of 750×16 tire for tubeless is 235/85 R16

So off I go to tire shop and change it… since I am using the stock rim, I opt for 750×16 tubed Xtra Grip tire… cost me US$ 120 x 4 fiuh…

The easy way of changing the tires is ask to the seller, what is the best tire for your rim or equivalent of your current rim…

but If you are geek… read on.. :

Crash course on tire size : There are three ways giving the description of tire size, the source of confusion… here you go..

American way: Height/width X Rim Size => I.e : 31/10.5×16 means: 31 inch diameter, 10.5 inch width, for 16 inch rim
Metric : Height (mm) / Aspect Ratio side wall height X rim size => I.e: 235/85X16 means: 235mm width, (235×85%=)200 mm side wall height for 16 rim.
Imperial: Width X Rims size => I.e: 7.5X16 means: 7.5 inch wide for 16 inch Rim imperial also means aspect ratio is 100% hence it equal to 7.50/100X16

I said earlier that the 235/85X16 (lets say tire A) is equivalent of 7.50X16 (lets say tire B)..? How come..? let me try to explain…

To make it easy, lets convert all to inch..? let say 1 inch is 25.4 mm.
Tire A: (235/25.4)/85 X16 = 9.25/85 X16 while tire B is 7.50/100X16
From the above, we know that the Tire A: 9.25 inch wide, and Tire B : 7.50 inch wide
So equivalent does not mean exactly the same, the Tire A will be about 1.75 inch wider.
Now how about the overall diameter..? this is where the aspect ratio come into place
The overall diameter formula is easy : (Side wall height X 2)+Rim size
Tire A side wall height would be: 9.25×85% = 7.86 inch, while Tire B side wall height is: 7.50 X 100% = 7.50 inch
Overall diameter Tire A would be (7.86×2)+16 = 31.7 inch, while Tire B would be (7.50X2)+16 = 31 inch
Hence: In terms of Diameter, Tire A would be 31.73 inch and Tier B would be 31 inch so tire A would be a tad higher
However when I compare it side by side.. the 7.50X16 Xtra Grip from Goodyear is a tad higher than Bridgestone 235/85X16

Confused…? mee too.. :D
