Here & There
Wednesday, June 24, 2009 at 10:10AM Gee . . . having a blog is hard! You have to write things and then post them! I have been very busy lately . . . and am busy today . . . so I will post only these four photos of what I have been up to in the last two weeks.
I went to The Philippines for 10 days and had a wonderful time in Manila and the Taal Volcano region. I took some amazing photographs that I have added to a Philippines album in my Travel Photo Blog link. Here are a couple of pics from the trip for now:
Looking down into the actual Taal Volcano crater lake (above).
I was lucky to have some really excellent light one afternoon at a roadside fruit market.
--------------------------
When I got back from The Philippines I immediately got to work with my friend Peter to renew work on constructing another drag racing car. This one a 1970 Maverick that will become a "275 Drag Radial" class-legal race car. I spent the last three days crawling around under it fitting a ladder bar rear suspension and housing floaters. It came out nicely! Here is a pic of the adjustable ladder bar installation as it is today. More reinforcement around the brackets needs finishing, and a new floor needs to be fabricated, but the progress is good. Go to my Racing Projects Blog section of this site for more details.

That & This
Sunday, June 7, 2009 at 11:58AM Another aborted attempt at racing last night! Peter and I got to the track, serviced the car, started it . . . it sounded pretty good . . . and then . . the dreaded miss and flashing red light from the ECU. Jiggle the wires . . . oops . . . it stopped running. We tore into the wiring . . . used a volt meter and discovered no power to the ECU now. Replaced the fuse . . . still no power. Hmmm . . . loose wire at the ECU . . . loose hell, it fell off! Re-soldered the wire to the clip . . . let's look round some more . . . . . what the hell! Something has been nibbling on the wiring! Rats and/or mice have been gnawing the insulation on some of the wire. This is not good! We wrapped these bare spots, started it up, sounds GREAT, and I took it to the 'practice pad' to test. Not bad . . sounds great . . . strong . . . but it loaded up quickly. It's too rich now because it is tuned for when the fuel filter was stuffed and the electricals were inadequate. Too rich . . . but my tuner is not here with the computer. Looks like I am going to have to master the ins and outs of tuning my own ECU. No racing tonight. Oh well.

Oh well, nothing to do but hang out with my buddies and do some photography. Andy dropped by with his amazing 850hp wide body street Supra. Nice!

I have added an entry with photos to the Thailand Photo Blog section (link above) of a day in the life . . . . . of me!
So . . . I went back to the track on Friday afternoon (June 26, 2009) with my friend and tuner, Khun Mac, to tune the ECU and to get the A/F ratio right throughout the rpm band under every load condition. We did a good job of that . . . did some parking lot blasts with the A//F meter working and headed toward the starting line for some test & tune 1/4 mile runs . . . and then . . . the dreaded ignition miss reoccurred. I wiggled some wires and the big wiring bundle and it made it stop for a while . . . until it came back. What to do? There is obviously a short somewhere in the wiring giving this periodic miss. So, Mac has arranged for the "best wiring guy in Thailand" to come out to the shop this week and tear into the wiring, replace as much wire as is needed, and eliminate the miss once and for all time. Sheesh! This is no fun. I would do it myself, but I (and Mac) both have bad "wiring karma" ("gamma" in Thai): whenever I touch automotive wiring I mess something up and don't know how to fix it.. Best leave it to the professionals. Stay tuned.
So . . . I finally broke down and hired an electrical who really knows what he is doing to come out to the track and trouble shoot the electrical problem. It took five hours of systematically testing and disassembling all the wiring from the ECU and checking all the sensors . . . and YES! . . . we found multiple small problems that yielded the big problem. Here's what we found: a corroded coil wire pin at the ECU, a shorted air temp sensor wire, a bad connector at the #2 injector, and two injectors wired out of sequence. All of these added up to a very difficult tuning situation. After fixing these problems, it started up, and revved very crisply with no miss or stutter . . . however, a few quick parking lot blasts showed an extremely lean condition . . . of course caused by trying to tune the engine with all those problems. I will re-tune the mapping in the ECU next week . . . and then . . . here is a pic of the MicroTec with the plugs and connectors repaired.

This & That
Wednesday, May 27, 2009 at 6:36AM I haven't sold the 1.5JZ in my race car yet . . . even at a great price.
Last week-end was a bit of a debacle for me at the track: An electrical gremlin pestered me all afternoon and evening. There was a periodic ignition miss that came and went. Unfortunately, it reared it's ugly head right when I was at the front of the line in the staging lanes on Saturday night.. I had to 'idle through' the track . . . but when I got to the top end I gave it the gas . . . and NO MISS! Frustrating! Peter and I fiddled with the wiring, but it still came and went. I will have to chase all the wires in the ignition system to find it. Oh well. I need to spend more time with the car. It was built five years a go and the heat and humidity may be taking its toll on insulation and causing corrosion. Time to run some new wire.
I have added many photos to the China, Australia, Studies of Stuff, and the My Beloved Thailand section of Travel Photo Bank section of this site. Please check them out.
I spent the morning in my shop chasing the wiring and, get this, reading the MicroTech ECU manual. I began to focus only on the wires to the coils and the power, ground, and crank position sender. Sure enough, I noticed that with the engine running, every time I wiggled the small clip for the crank position sender, the red warning light began to flash. I got some cleaner and a small pick and "re-connected" that wire to the brass clip, restarted the motor . . . . and no more miss, no more warning light . . . . no matter how much I pulled, wiggled, or moved around the warning light would NOT COME ON. Also, the motor was much stronger . . . absolutely no missl Too bad it was raining or I would have tested it. Here are some pics from today.
Clean shop . . . right before it started raining!
This is the 'Office'. The electrics are easy to get to. The fuses and relays are in the 'glove box'. Switches and controls are all within reach. The Microtech ECU and Dash Unit are there, the programmable trans controller (PCS) is easy to get to. Some gauges, but who has time to look at them during the run. The AEM wide-band 02 gauge is the only one I peek at in 3rd gear.
Building Race Engines in Your Mind
Saturday, May 16, 2009 at 10:23AM If the old saying, "Drag racing is not a sport, it's a disease that once contracted has no cure" is true, then one of the main symptoms of the drag racing disease must surely be 'building race engines in your mind.' I suffer from this terrible affliction, and am no doubt in the tertiary phase. My thought build-ups, and mind-dyno efforts have lately been turning towards putting a V-8 into my little race truck. Although I love the idea of my little 191 cubic inch straight six running in the mid-10s on gasoline, I have to admit I am beginning to notice a new symptom of my disease: "Wup Wup envy." By "Wup Wup envy" I mean I miss the sound of an unmuffled (a turbo is also a muffler, in a sense) race V-8. The "Wup Wup" sound of tickling the gas pedal; the lopey idle; the roar of the open headers at full song under power. Ah, the music of a V-8!
Which V-8? I live, work, and race in Thailand. Yes, I can import a Chevy or Ford V-8 from The States or Australia for cubic dollars, but I would also have to import everything to keep it running forever after too, for more cubic dollars . . . and there are no machine shops here familiar with U.S. iron. What to do? It just so happens that Thailand is the car-breaking (disassembling) capitol of the world: wrecked cars ("totals") from Japan end up in Bangkok for disassembly into containers of various components. It's cheaper to do that in Bangkok than in Tokyo. The good news is that Toyota made a wonderful 6-bolt main V-8, called the "1UZ" from the mid 1980s on that is incredibly cheap here. It is a stout 4.0 litre (242 cubic inch) DOHC, 4-valve, all aluminum wonder that is actually 90 pounds lighter than my current (iron block) 3JZ straight six. My current race modified auto trans and high stall torque converter will actually bolt up, and, did I say this before, they're cheap.
But . . . . I cannot make the 500+ horsepower on gasoline easily with a 242 cubic engine without turbocharging it (no "Wup Wup"!) . . . unless . . . I SUPERCHARGE it. Soooooo . . . it just so happens that a freind of mine has a Vortech V9 supercharger, and another friend has a set of new-in-the-box Kelford race cams for the 1UZ . . . at fair prices . . . . with some head porting . . . . headers . . . around one bar (14 pounds) of boost . . . with stock internals and injector manifold . . . equal length headers . . . big injectors . . . . maybe I can get the 500+ horsepower . . . to run the 10s in my 1900 pound racer . . . . Hmmmmm . . . what to do?
This is the Toyota 4.0 1UZ V-8. Very nice, no? All the covers and crap would come off, of course.
This is a Vortech V9 supercharger. It is SMALL, but can be driven at tremendous speed (max 65,000 rpm). It should give me the boost I want. I am not looking for the ULTIMATE set-up, but reliable horsepower that can give me enough power to 'run on my number' in the e.t. brackets here.
Hmmmmmm . . . what to do? . . . . my little truck with a V-8. I must satisfy my Wup Wup envy! I must satisfy my Wup Wup envy!
I will sell my 3JZ.
So . . . . . I have had my current '3JZ' race car engine for sale on a Thai racing 'engines for sale' site for over a week now and have had a good number of interested buyers . . . . but no cash in my pocket yet. I have lowered the price, but still no luck. I am asking a really low price for it; much lower than you could build it . . . but . . . . .
In the meantime I have been educating myself on the ins and outs of the 1UZ V-8. Thanks to my good friend, and 1UZ aficionado, John, I have figured out what my 550hp supercharged engine build sheet will look like. We will see.
There is a lively discussion of pistons and rods for my project on the Lextreme Forced Induction Forum. Check it out.
The Toyota 1UZ is a very attractive "HEMI" (actually a 4-valve 'pent-roof' design) when all the covers are removed. Thanks Smithers for your great web site on the 1UZ. Enjoy these photos from his site:


"Project 1UZ" progress: I purchased (1) a very good "early, big rod" 1UZ complete, (2) a 1UZ automatic bell housing (so I can use my current race-modified 2JZ A340-series automatic trans) , and (3) a 1UZ flex plate modified so that my current 2JZ bolt patterned torque converter will bolt on. I also arranged for a custom "Moroso-type" rear-sump oil pan to be fabricated and firmed up the purchase of the set of Kelford 264 cams. I also made a final decision as to how to proceed with the build: Phase 1 - standard internals + take the heads off to put in a high quality slightly thicker head gasket using the standard head bolts to put it back together + rear sump deep oil pan + 550cc RX7 injectors + VorTec V9 supercharger + individual Bosch coils + equal length merge headers +Autronic ECU (SMC-4). That should get me started with a conservatively (rich) tuned V-8 motor that will allow me to be competitive in the 11.90 (and slower) bracket at Bangkok Drag Avenue. Phase 2 - add head porting + large ARP head studs + aluminum rods with ARP bolts + oversized forged CP pistons (9.0:1 and 4.4 liters) + more boost (14 pounds) + 150hp NOS and controller so I can qualify for a new "Top Truck" class (in the 9s) where the top 8 or 16 trucks have to qualify by low e.t., but then can dial their own handicap (much like Top Dragster in The States).
1UZ Big Rain - No Racing
Tuesday, May 12, 2009 at 10:11AM Peter and I hung out until late and then it rained. Oh well. Here is another video clip of the Familia race truck launching against the two-step - in November 2008. Nice sound, no?
