Hari malang aku #2

Semalam aku balik dari bengkel.. dan punca dah dipastikan.. rupanya termostat aku problem.. tu yang overheat tu.. ish ish gerun aku tgk engine aku...



depan belakang pecah macam tu.. huhuhu.. macamana aku bleh tak perasan temp naik..



gambar engine lantai yang baru beli...

p/s thanks to Fahmy
(kebetulan lak nama sama ngan aku) owner bengkel Sysmantech Technology kerana melayan kerenah aku.. huhuhu Sapa-sapa nak buat engine atau nak buat nuckle dan segala benda enginerring.. bleh dtg kedai dia.. kat tmn technology kajang.. dekat ngan Billion.. atau Contact 012-258 3962..

Hari Malang Aku





Kelmarin 17/02/2009 merupakan hari malang bagi aku... tak pasal kete aku breakdown.. check- check rupanya head gasket dah pecah... berterabur minyak hitam.. nak kata merembat tak jugak.. rasanya x bawak lebih 100km/h pun...

Semua ni angkara water pump x jalan.. lepas redah jalan jem teruk.. aku lak bleh tak perasan temp kete naik.. tau-tau sedap2 tengah bawak.. bunyi semacam jer kat engine.. berhenti tepi tengok.. fuhhh.. berterabuk minyak hitam... dia nak duit la tu..

Thanks pada Azhari (Ofismate lama aku) dan juga Lan Nemo (KJ Motorsport) yang sudi membantu aku.. tak lupa juga pada member lan.. aku tak tau apa nama diorang berdua.. siap calling member towing dan bawak bengkel dia malam tu gak.. Terima kasih banyak-banyak.. kalau tak layan syahdu la tepi highway cheras batu 9 tu sorang-sorang..

Total cost yang bakal rabak...

Engine Lantai L5 = RM550 <- Thanks Lan sbb dapat murah Upah turun dan pasang engine = RM250 Upah Towing = RM90 Minyak hitam dan lain-lain = RM100 Jumlahnya = RM990 ... Kalban la aku bulan depan... huhuhuhu.. sabar-sabar... ni semua dugaan.. Yang penting aku tak apa-apa... duit abis takper.. jgn aku yang abis.. kesian anak aku yang bakal lahir tu...

DIY : Seat Belt Mira Mira kacuk motor kancil

Ramai yang merasakan seat belt mira tak lock bila kita pasang di kancil. kat sini aku ada jalan penyelesaiannya.. semudah 1 2 3... hehehehe.. apa guna mira mira... tapi tak ada safety... so korang ikut step2 yang di tunjukkan:-


1. Gambar di atas adalah perbezaan antara motor seat belt mira dan kancil


2. step pertama... korang tarik sampai habis tali dia.. hingga nampak roller kat dalam... pastikan untuk tarik tali pinggang tersebut.. motor perlu tegak... kerana bila senget.. motor akan lock tali tersebut...




3. Keluarkan hujung tali pinggang tersebut... dan keluarkan selak yang digunakan...


4. Kemudian lock kan roller tersebut dengan skrew driver kecil supaya dia tidak boleh berpusing.... gambar diatas contoh yang aku telah lock... step yang sama.. juga untuk korang buat kat selt belt kancil/mira


5. Yang terakhir... ambil motor kancil.. dan masukkan kembali tali pinggang mira2 kedalam motor... dan masukkan selak tersebut... keluarkan skrew driver yang gunakan untuk lock roller... dan lepas roller... dan kini... seat anda boleh digunakan seperti sedia kala.. tanpa perlu... membahayakan diri anda dan keluarga...

Selamat mencuba

The "D.I.Y. Manual Boost Controller"

The "D.I.Y. Manual Boost Controller"

....Home Depot™ style
This controller was conceived from deep within a tight pocket, along side the lint and gum wrappers. There are two reasons I made my own MBC. First, I was not going to spend money on an expensive MBC (though I did want something that would properly and effectively control boost). Second there was the challenge to build it and be able to think "heh.. see.. I didn't need to spend 50 or 100bux to buy a pre-made one!"

I'm sharing it with you... If you have even the slightest bit of mechanical ability you can make one of these; building this MBC won't cost you more than about $12 in parts from the local hardware store and an hour or two of your time...

NOTE: Before making and installing a MBC you MUST have a Boost Gauge installed to monitor the changes you will be making while adjusting your boost. Failing to do so may result in nasty engine destroying demons attacking your engine. I would also highly recommend doing the fuel pump rewire mod if you plan on increasing boost beyond 15 pounds (DSM fuel system mods can be found at "http://www.vfaq.com/" ; "http://www.vfaq.com/mods/pump-relay.html" & "http://www.raktron.com/fuel/rewire1.html")

The Parts:
all of the following parts should be available at the local hardware store, in my case, it was Home Depot in the air tool section.

· 1/4" NPT Tee (I'll refer to it as the 'Body')
· 1/4" Male NPT coupling
· 1/4" Female NPT x 3/16" hose barb
· 1/4" Male NPT x 3/16" hose barb
· 5/16"-18 x 1 1/2" SHCS (I'll refer to it as a 'Bolt')
· 5/16-18 Jam Nut
· 1/4" dia ball bearing (I actually purchased mine from a bicycle shop)
· Spring ~ 1.69" lg x 3/16" dia
· Straight thru 3/16" plastic hose barb coupling (commonly used in windshield wiper systems)
· length of 3/16" I.D. vacuum hose to connect MBC

The Tools:
· drill
· 1/32" drill bit (to drill vent hole in plastic straight thru coupling)
· 5/16"-18 UNC tap
· hack saw
· teflon tape




The Procedure:
1. Cut the top part off the coupling using a hack saw as shown. I will refer to this piece as the "Cap"

2. This is what the Cap will look like after being cut. Discard the piece you cut off.

3. Since the hole thru the fitting is already slightly over .257" (required taps size for a 5/16-18UNC thread) drilling to the correct size to tap is not necessary. Tap the Cap all the way thru. Make sure the hole is tapped straight (concentric to the hole)

4. Take the jam nut and thread it part way up the Bolt. Wrap the Bolt with Teflon tape, to prevent air leaking between the threads, and thread the Bolt and nut into the Cap, place aside for now. I will refer to this as the 'Cap Assembly'.

5. Use some teflon tape when threading the following together... take the male hose barb and thread it onto one end of the tee. Take the female hose barb fitting and thread it onto the middle part of the tee.

6. Place the ball bearing into the tee, so that it is now sitting at the bottom against the Base. Gently follow with placing the spring down on top of the bearing. Now take the Cap assembly and using some teflon tape thread it into the tee.
Note: The dimensions I have given for the spring are what worked for me. Your spring will have a different 'rate' and therefore will act differently, a little experimentation for length and compression is required to find what works for you. MAKE SURE the compression on the spring (from the Bolt) is completely released and increase compression on it, which increases boost, gradually.

6a. Here is a basic cutaway view of what the internals will look like once the controller is completely assembled. Because the spring is sized closely to the inside of the Body, there is no need to modify the Body or spring to eliminate any lateral deflection that might occur if the clearance between the two components been greater.
As a side note, a second ball bearing can be added between the spring and the Bolt. I've found though, that due to the spring's size, it seats fairly well on the Bolt without binding (which could cause problems with adjustment accuracy) and doesn't require it.

7. Carefully drill a small (1/32") hole into the body of the MBC as shown by the arrow in the cut away aside. With the bleeder hole in this position the same end result is achieved as with the coupling, but it reduces the number of parts required to fabricate and install the MBC.
The bleeder hole is not large enough to affect the signal to the Waste Gate but it is necessary to gently vent off excess vacuum or pressure in the line which causes a type of signal lock. If the hole wasn't put in, the controller would have difficulty controlling boost above about 15 pounds.

8. Attach this 'bleeder' to the fitting on the side of the MBC with silicone hose. Attach a piece of silicon hose to the other side of the 'bleeder' this line now goes to the waste gate.

9. Take another piece of silicone hose and attach one end to the Base of the MBC and the other will tee into the signal line between the BOV and the manifold.
Refer to the above Schematic for a visual layout of what I have just explained

The Result:
You can now begin to adjust your boost by turning the Bolt in or out of the Cap (turning the Bolt in, will increase boost; turning it out will decrease it). This places resistance, thru the spring, onto ball bearing which will reduce or increase the signal that the waste gate sees (thus controlling the boost). Once you find the 'sweet spot' of the controller, you will notice that it should only take minor adjustments to the Bolt to increase or decrease boost. Once you have achieved the desired boost setting, snug the Jam Nut against the Cap to lock the position of the Bolt.
