    Dual Tank Plumbing Advice and Considerations

    Walt- Figure your fuel consumption at 0.5 lbs per horsepower- hour. Multiply your horsepower (470 BHP) by time (1 hour) and multiply by 0.5. This gives you the amount of fuel consumed in one hour in units of pounds. To convert this to gallons, divide by the weight of gasoline in lbs per gallon...

    I only caught the 4-legged ones doing it, Larry. ;)

    Yes, Howard, it sure did. The car is geared for 209 mph at 7200 rpm and I think it can do that. If you've never been to Bonneville, you should plan to go. Speed Week in in August next year and is the biggest land speed racing event. World of Speed is in September and much smaller but...

    Problem with "rear gulf arches"

    It might be a good idea to replace the old bolts with new ones from the manufacturer as long as you are taking your wheels apart.

    Wire vs Halibrand Wheels

    One downside to magnesium wheels---- I bought a 1965 Pontiac GTO when they first came out and put a set of American Racing magnesium wheels on it. These were real magnesium, not fake aluminum "mags" and they were polished nicely. Dogs would come from miles around just to pee on those wheels!

    Problem with "rear gulf arches"

    Any manufacturer of modular wheels should be able to customize the wheel offset to suit your needs. Bill Jongbloed used to build high quality modular wheels but I think he sold the company some years ago.

    Thank you, Randy and all the others who have commented. It is clear that this car is far faster than this run. I just shifted to 5th from 5k rpm in 2nd and let its torque build the speed up to 157. The salt was so hard and dry that I left black tire marks off the line.

    The salt surface was unusually hard and smooth this year. This was only a test run to evaluate the car's performance , not an all-out high speed run. I feel sure that the car will do its calculated 209 mph at 7200 rpm. Maybe next year? https://www.youtube.com/watch?v=Hr5zG5r35C8

    It's Monday morning and I'm back home in Tucson. We left Wendover yesterday morning and arrived home late last night after an 800 mile drive hauling the car on a trailer. We lost 3 hours getting our trailed fender re-welded in Boulder City, Nevada. The vibration had cracked a weld but Sparc...

    I hate to be the bearer of bad news but from what I've heard, you are simply SOL. Move on.

    A bench-mounted 4" to 6" belt sander is a real asset. Use 3M Cubitron II abrasive belts and you can even grind titanium. It's great for finishing the edges of fabricated metal parts and for radiusing square corners. A 4" or 4.5" angle grinder with a 3M bristle disc is useful for de-burring...

    Craft Performance engine knock

    This is a difficult situation that you are in. Here is what I'd recommend: I'd approach Lance at Craft Performance with that dyno sheet in hand and ask him (not demand- things can go downhill in a hurry) why the numbers are so far off. Something was not right during that test and the engine...

    Craft Performance engine knock

    The data above 5400 RPM makes no sense at all. The air/fuel ratio over the whole RPM range should be close to 12.5 to 1 at full throttle and it's reading above 14 to 1. That's a pretty lean mixture. Above 5400 RPM the numbers are not believable. The timing could have been correct when it was...

    Craft Performance engine knock

    You didn't say what engine this is but if it is a small-block Chevrolet (SBC), it is 6 degrees to far advanced. It isn't the their fault.
