  1. They put GPS units in artilliary shells so durability doesn't have to be an issue.

     

    Go to summit racing or jegs and find a digital speedo you like. They also sell sender units that hook into a mechanical drive and convert it to electronic.

  2. Trucks are usually cammed for low end torque and a nice fat powerband. Sometimes they match that with narrow runner heads and intakes to keep the flow velocities up. All of that means they don't always breathe well at higher RPMS thus giving up ultimate performance for low end grunt.

  3. I have done this a few times. Just keep it well ventilated with plain ole air and you will be fine. The inert gas isn't going to do you any good unless you can keep it continuously filled with the stuff. Plus you will have to go through the better part of a cylinder to display all the air in the first place.

     

    Trust me.

  4. I just drained mine and rinsed it out with water. I also made sure I vented it well before drilling or welding on it. I placed an air hose inside the tank and left in on when working. Don’t let the air stagnate.

     

    There were a couple of recent threads on modifying tanks that I thought were quite excellent. Had lots of pictures and excellent ideas on how to build an internal swirl pot. Using the drain plug is common, but since you don’t mind welding on the tank I think you can do better. Coming in through the side of the tank will keep the stock look.

     

    Ahh. Here it is. It contains a link to an earlier thread.

  5. In 10 years of racing 240Zs (probably 60,000 track miles) I've had two fail. And that was with 225 width tires and 200 horsepower. Once I polished the fusion weld area, kept my stubbies clean, and inspected them every month (along with the rest of the car) I never had another failure - even with 275 width Hoosiers and 320 horsepower.

     

    How many have you replaced because they failed a monthly inspection? And would you have bought the MM ones had they been available back when you actively raced?

  6. Well I was hoping more people with first hand experience would chime in.

     

    My biggest worry is the degree of damage that could result should one fail while driving. When the stub breaks the whole wheel comes off the car. Rear disk brakes will at least keep the wheel in the vicinity of the car.

     

    I don't know what the risk of breakage is but I do know the potential damage when they go is totally unacceptable to me.

  7. Read what again exactly? I didn't read all of Pete's stuff cause the equations were pretty easy to derive. If I use Vinh's numbers for the sender resistance and the guage numbers from Teakass's link, I can't get a solution that doesn't require negative resistances. I did double check it with Pete's spreadsheet and it said no solution also. I ran it a second time with the numbers you posted for the Ford guage (which summit doesn't carry in the style that Teakass linked) and that had no solution also.

     

    Maybe the sender numbers are not correct, or maybe there is a solution that is close but not exact.

     

    Do you remember what resistance values you used?

  8. This has come up before and I think most people say there is no real reason to go bigger on brake lines. Especially with stainless steel flex lines. You're just not moving much fluid.

     

    I have read articles saying bigger line should be used for clutch hydraulics since they have to move a larger volume of fluid quickly. There is (or at least should be) a larger movement in a clutch TOB than in a brake caliper.

  9. If the numbers Vinh gave for the sensor resistance is correct (and I have not reason to believe otherwise), then Pete's method isn't going to work for this solution.

     

    There might be a way to hook up a passive resistor network different from Pete's that returns the correct results, but it would require too much thought on my part right now. It could almost certainly be done with some type of active (op-amp) circuit.

     

    But For $25 just send the guage to Autometer and have them do it.

     

    Personnally I like the cheesy look of the stock guages.

  10. Sometimes you just have to bite the bullet and take it into a shop. Especially if you need it for work.

     

    This type of thing is difficult to troubleshoot over the web so it is not like I am not being helpful.

  11. This place has an excellent rep for selling motor/trans pull outs

     

    They have a complete 95 impala SS pull out for under a grand

    Looks like the price of LS1 motors have gone down a bit in the last year. The 2001/2002 motors are more desireable due to better intakes and block oiling. Corvette motors just cost more than the F body motor (don't know why). Manual trans pull outs are a good bit more than autos.

    Prices on LS2 motors are such that you are probably better off buying a new crate motor.
