    Crimping Tool for Weather tight Connections

    in Miscellaneous Tech

    Posted

    I'd get a weatherpack crimper that does two crimps in one. The one for the wire has open barrel that "folds" the terminal, but does is with parallel jaws, not like a pair of pliers. The other crimp is for the seal, which makes a perfectly round crimp. There are other variations like metri-pack that uses a different crimper...

     

    Crimping tool ($130)

    Removal tool ($5 Good advice, BJ)

    http://order.waytekwire.com/productdetail/M37/421

     

    I'd recommend a spare removal tool too, since I found they can be bent pretty easily.

     

    The crimpers work great...even better once you have a lot of practice :D

     

    Hope this helped...

    Air-conditioned Intercooler...is this possible?

    and oh yea good luck running a turbo car on battery power, i know from experience its not going to work very well

     

    Thanks for the Ford info...maybe someday I'll get some kind of "hyper-drive" system together..hehe :eek2::icon14::icon15:

     

    I doubt that a turbo motor would drain more energy per quarter mile than an n/a would. I was just trying to say that a super-cool IC would be super-cool!! :2thumbs:

     

    Muhaha!! ...Back to my "Mad-Scientist" lab. :icon43:

     

    Please keep the feedback / ideas coming...:?::P

     

    I appreciate that. Laterz, -hughdogz

    Post your "MacGyver" stories...(doesn't have to be car related)

    Hey Guys,

     

    I posted one of my "MacGyver" stories in this thread and I thought it would be cool to hear other ones too!

     

    In case you don't know who MacGyver was, here is the Wiki clicky.

     

    Story #1:

     

    I had a '78 Celica that I drove across the country (Portland to Chicago for college). Somewhere in Idaho, I spent the night at a rest area, not knowing that I had my foot on the brakes (all night) and it drained the battery.

     

    Luckily, I was on a big downhill slope, so I tried compression starting it, but no luck, there wasn't enough juice left in the battery to energize the coil...sheit!

     

    Then, I thought long and hard...where can I get some "electrons"? I remembered that I have some D-cells in my Mag-light flashlight. I taped six of them together in series with some good 'ol duct tape. Then used some speaker wire to connect them to the battery...

     

    Went to compression start it again, and Voila!! Instant Success!! :icon43::icon14:

     

    Story #2:

     

    Same '78 Celica, same road trip...

     

    I was getting bored on the "long haul" and thought it would be fun to see how close I could get to empty on fuel before filling up again.

     

    So I'm really near empty, and I pass an oasis...it says next gas 48 miles. I want to play the game...so I think, "sure, I can make that" :mrgreen:

     

    I get to the next oasis and it is *ABANDONED* :banghead: ...Holy Cow...I think I'm dead (still somewhere in Idaho near Idaho Falls? on my way to Yellowstone). The next gas is 30 miles. I get another ten miles or so and the car starts sputtering, so I pull over...

     

    I figure there must be some more gas in the tank that the fuel pump cannot reach. I pull out the Haynes manual and it says I can access the gas tank through the access panel in the trunk. Sure enough, I see the fuel pump inlet is about 1 inch (~2.5 cm) above the bottom of the tank, and there still some fuel! :shock:

     

    I disconnect the the fuel pump and drop it down into the remaining gas...it starts back up, and sure enough..I made it to the next station!! Whoo Hooo!! (even then, the station is closed, but I wait until it opens the next morning...)

     

    To this day, I'll NEVER try that game again, LOL...:lmao::rolleyes:

    Hi John, now that is not a bad idea either. Thanks! :icon14:

     

    I also thought of making an IC jacket that can be filled with dry ice, that way, no dripping! (just need to figure out what material to use as a conductive blanket)

     

    I do like the refrigration idea for heat soak during road racing though...maybe the Wolf ECU could monitor the Intake air temperature and kick on the compressor as needed :wink:

    Hi Guys,

     

    I'm wondering why this hasn't been invented yet. I'm interested in opinions on whether or not this would be feasible.

     

    I know there are IC sprayers, N20 sprayers, etc. My idea is kind of a hybrid air / water IC and an air / air. Either that or it is just a glamorized air / water. :D

     

    I think as a first prototype I could simply route the evaporator lines "around" the IC, instead of integrating them into the core.

     

    I know there is the whole conservation of energy law, and it would take energy to run the compressor. I thinking the primary use would be to make the IC super-cool before a run at the strip (and while going down the strip). If it could be an electric compressor, this would reduce the parasitic losses if the alternator is disconnected.

     

    Am I just pipe dreaming or do you guys think this is a viable option?

     

    Thanks, -Hugh

    Quick technical question for those that know...

     

    If your battery is as dead as this, will ROLL starting it work? I would think not... now how about if you are on a small hill, lets say one that is flat enough that worse comes to worse you can still stop the car with strong foot power?

     

    [Edit: I'd say the answer is No...I doubt that the alternator spinning at that low an RPM could generate the current / voltage required...]

     

    Haha!! I have this great "MacGyver" story...

     

    I had a '78 Celica I drove across the country (Portland to Chicago). Somewhere in Idaho, I spent the night at a rest area, not knowing that I had my foot on the brakes and it drained the battery.

    Does This Sounds Like A Dying Walbro Fuel Pump?

    in Fuel Delivery

    Posted

    Hi Yasin,

     

    I don't know if this is the cause of the issue, but I couldn't get above ~4500 RPM due to a clogged Catylitic converter. I doubt that is your problem.

     

    You have an SDS or megasquirt? I know the OEM EFI would throw a fit at ~3500 rpms if all the ECU, etc. connections are not clean.

     

    I wish I could help some more...perhaps more experts will chime in.:confused:

    Smoke On Deceleration

    in Trouble Shooting / General Engine

    Posted

    I appreciate the kind words, John. :wink:

     

    The way I have it set up is going from the engine block breather => hose => Catch can => Hose => PCV in the intake manifold.

     

    It catches some really nasty "blow-by" oil, but I still see some collecting in the return line. This says to me that it isn't catching all the catch can can. :D I wonder if I mounted it lower, gravity would keep more of the oil in the can...if the vacuum is high enough, I don't think it would matter too much.

     

    I've never taken apart my Cusco catch-can. I wonder if it has some sort of baffle inside, like an air-water separator for a shop air compressor. I think some kind of stainless gauze might trap the oil better too.

     

    HBZ member "hughdogz" uses a PCV oil separating tank that would solve this. Take a look at the below picture of Hugh's engine. You can just see the hose going the the tank next to the master cylinder. Maybe he'll chime in and give us more details.

     

    BTW, Hugh's engine is even more beautiful in person then it looks in the picture. :D

    My roommate in college was also an M.E. This guy was super-brilliant (book-wise).

     

    He was going from his BSME straight to a PhD, had an internship at Sandia Nat'l laboratory doing weird FEA CFD on how bubbles form...:hs:

     

    Anyway, we started talking about cars one day, when I said I had to go change the oil (myself for the '78 Celica). He said although he is a great M.E. he knows nothing about working on a cars (no biggie).

     

    Then he said he's always wondered why there are different types of fluids in a car (oil, coolant, brake, tranny, etc.) and why can't we use just one type? I got a kick out of that...explaining that hey, the fluids need to have different material properties for various reasons. :D

     

    [Edit: TonyD, here is my take on the situation...

     

    1) There are some people that know nothing about everything (meaning, they are a "Jack of all trades" yet they are not an expert in anything in particular)

    2) There are some people that know everything about nothing (meaning they are so specialized that they cannot even tie their own shoes or clasp a safety belt, change their own oil, etc.)

    3) There is a balance in between...Yasin knows what I'm talking about (thanks again Yasin
    :P

    Moving to Portland, what areas should I avoid?

    Looking to rent a house. How's the Milwaukie area? Thanks.

     

    Dude! Move out here already...:icon43::icon14:

     

    Milwaukie is great...nice old suburb. I have met some really cool friends out that way, and nothing is really more than ~20 minutes away in Portland on the freeways (unless it is rush hour, and then it could be two hours some days...)

     

    Hope to hear from you again soon 24OZ'er :D

    Engine of the future?

    Hi Challenger, I totally agree and wonder that myself...

     

    What is invented and what is implemented into production and status quo is another discussion altogether...

     

    As I walk around my neighborhood, I cross some old concrete bridges...some of them say "made in 19XX for the Portland electric trolly". If you pay close attention, all the roads / bridges / infrastructure is based upon the (currently implemented) technology

     

    Yes, I agree that we are in need of a new "revolutionary technology" but it hasn't happened yet. Electric cars used to be more popular than IC cars. In the infancy, we had no "gas stations" what we had were horse-driven carts, like taxis, filling up cars on the street (like a waitress at a bar, hehe) who knows what octane, methanol, ethanol, etc. we were using. :wink:...I digress...

     

    The way I see it is that we have only so many fuel and energy types (chemical, electro-magnetic, thermal, solar and nuclear). We can only make engines work with what we have, and we can only design the engine to harness the energy with what materials, machining processes and tolerances we have at hand.

     

    I'd love to see a 1000 HP engine that doesn't have any impact on the environment (until you take a corner too fast or else the brakes can't handle :icon54::icon14:)

     

    It is true, you can design the engine to use different thermodynamic cycles (Diesel, Otto, etc.) However, if the Carnot efficiency holds true, we cannot gain above ~33% efficiency in an engine.

     

    What I would like to see is something based upon Tesla technology where we'd use the resonant frequency of the Earth to harness magnetic (and maybe anti-grav stuff) to make "free" energy vehicles. Sunday Sci-Fi... :roll::D

    Skib, no way you'll be able to get antique plates in Oregon, since your car wasn't built in 1954 or prior. We don't have "Historic Vehicle" plates like California...

     

    What we do have is Special Interest plates, and your 240 is already at least 25 years old. Special interest means you can only drive to group events, shows, races, etc. (but no mention of mileage) Oregon Plate Types link

     

    What would be really cool is to find some vintage "Pacific Wonderland" plates and have those transferred to your 240Z:

     

    plpacwnr_small.jpg (I bet you don't see many of these around anymore)

     

    I don't know if it is possible, but I know you can keep the same plates that were issued at the time your car was first registered...I think these might be the "Period Correct" plates. :mrgreen:

    Which ones do those tests Hugh? The DEQ?

    I would assume any of them can do it (DEQ = Clean Air Station). When I had to get my 1982 tested, there is a place on the test results that said noise level and it said pass. I assume that if it is on the borderline or above, they have the equipment to measure it and mark it as fail, if needed.

     

    I tried to test my 1969 Volvo 1800S at DEQ once for emissions back when it was running b4 I took it down for restoration and they wouldn't do it because the car was too old.

    I know for a fact that Gary Moissant did it. I don't see why the DEQ would refuse, unless they are totally slammed that day. Even if a car is pre-1975, you'd think it would still be in everyone's best interest to know how the emissions are measuring. I bet if you asked nicely they would comply. :wink:

    The job thread. What do you do for a living?

    I work in the CAD industry. I used to do contract work, designing fixtures to inspect turbine engine castings, modeling turbines from 2D drawings to 3D, reverse-engineering castings for pattern shops, etc.

     

    Now I test the software I used to use. For the past few years, I've been testing the Simulation (CAE) software that works on top of the CAD software used mostly for machine design. Dynamic Simulation and Stress Analysis (FEA).

     

     

     

     

    I really like my job a lot, but it has been challenging and time consuming lately. I work closely with a worldwide team of mechanical and software engineers (US, France, Czech, China). It is cool when I get to travel (which doesn't happen very often lately). But conferencing with other time zones can get old fast.

    There are no real dangerous places to live in Portland, compared to some big cities like Chicago or L.A.

     

    I second lgoodson:

     

    We have a wedge sector model of the city...out toward SE 82nd it is nicknamed "felony flats" where the tweakers and hookers proliferate. There is also N. Portland where some crackheads tend to hang out.

     

    However, like most other U.S. cities, we have been undergoing re-gentrification. Some of those areas that were once considered "bad" are actually a very good place to move into.

     

    The "rich" part of the city could be considered the west side (either SW or NW). It was even mentioned by Art Alexakis (sp?) in that Everclear song "I will buy you a big house way up in the West Hills...".

     

    Hope this helped...

    Need help with wastegate actuator

    I have seen the spring on the outside trick, but I need to do some more reading on that. As for lengthening the rod... won't this open the flapper a little bit?

     

    It may do that if you lengthen it too much.

     

    Now that I look closer at the photos, I can see how the P.O. modded it to be a higher boost level. I think they opened up the canister and added another spring, or replaced the OEM spring with a stiffer one. Then they welded on some tabs to seal it back together.
