Melissa's Mustang ran 1.42 60' times on its way to 6.70 ets @ 100.05 mph last weekend. Is that ok?My junk ran 1.60 60' times on its way to 7.21 ets @ 95 mph. Is the 60 slow for the et? Are these times normal or what? We don't get to run the 1/8th very often and thought you'all could enlighten us. SteveW

Melissa's are about right Steve.
1.40 would be perfect.
Your's are about a dime slow unfortunately.
1.60 is what Tony's Carpi runs at 7.90 1/8 mile ET.
You should be in the low 1.50 range.------------------

Alex,That's what I was thinking, I've got a $190 converter and tall 3.70 gears and dot tires. I've still got to get the cal-tracs dialed in too.  Thanks SteveW

When we run the numbers and convert to 1/4 mile ets both cars should be faster in the 1/4 than they are. For instance the Dart should run a 11.2-- at 120 mph and it only runs 11.48 at 118 best. The Stang should run a low 10 at 128, and it's best is a 10.58 at 124. I'm wondering if my cheapo fuel systems are being maxed out before the second 1/8 mile..... My junk just has a 5/16 stock fuel line with a holley mechanical pump, Mel's has a 3/8 s/s line pushed by a holley red and pulled by a aftermarket mechanical pump.SteveW

What kind of suspension do you have on your 66. I just picked up a 66 with a 342 and want to make this into my track car. Any advise would help. Also if you know any good shops in socal let me know.

The 1/8 to 1/4 conversion tables are inaccurate from what I have found Steve.
Mel's car is on the money.
Your Mopig is a stone off the line and obviously needs help.With a 1.60 sixty it is leaving like a school bus.
Did you paint it yellow?  ------------------

Efficiancy, or in the Dart's case, lack of it. Not able to apply the HP it is producing.
New (correct)converter will cure that.
Et will come down, but speed will remain close.------------------

At the carb, one full gallon in under 30 seconds is adequate Steve.
If you still have that mechanical pump, ditch it.------------------

Alex, speaking of fuel systems, I also have 5/16" line from the tank to the mechanical pump. I got a Holley Blue and am going to install it this winter and ditch the mechanical. Do I need to upgrade to 3/8" line or will the 5/16" line do? ------------------

Thats kinda what I was thinking about the fuel line size. I have less than 2 weeks left of this college semester and then we get a month break. I think BLStangin and I were gonna drop the tank and enlarge the pickup size to 3/8" and run the line from the tank to the engine. What kinda springs did you find? Be nice to have a set that keep the ride height about the same but have some movement instead of my lowered ones.------------------

Blue,
Nice time slip. I think I'll upgrade the Dart's fuel line this winter to 3/8" and add an electric pump. That will help, until I get ready to stroke the 440 to 500 c.i.'s. These mopigs need lots of cubes. (well not really, but it is the easy way to make reliable h.p.) SteveW

Your car is loosing 60 foot due to lack of traction.
Your big speed can be mostly attributed to having a stick.
If it was to hook, your 60 foot should be about 1.50.
Double that, deduct it from your 1/4 mile ET and all computes about right.
11.20 @ 116-117.
That real world experiance formula works 99% of the time.

1000 9.623
1320 11.573 115.0 Mph On a run with some spin at the launch the 1/8 mile Mph was 95.71.  I think that the 60 foot time is slow in comparison with the rest. Any suggestions? Hans. ------------------

Well I'm sure I'm off on my 60 ft compared to my other numbers but I have made progress in that area. I'm still working on it and will get in the 1.40's next year! Here is my best run, 1.51 60ft, [email protected] 1/8th, and [email protected] in the 1/4. I have run 1.51 several times but always with some wheel spin, I can only launch at 4500 or it'll blow the tires off. This is in a heavy 4-speed street driven car.

xr7,That's great for a heavy street driven ride. My junk is heavy and has to drive itself to the track and runs on d.o.t. tires. Just isn't making your h.p. yet, but it's fun. My track weight is 3600 pounds, what's yours? Melissa's runs quicker 1/4 miles than yours with less mph. It gets it done off the line. Lots of quick Fords on here! SteveW

1/2 fuel line with a 280gph pump up to 650cfm carb.over 650 cfm carb u may won,t 2 1/2 fuel lines & 2 pumps this may be hard to do on a street strip car with out a fuel cell.Its hard to over kill a fuel system. the harder a car leaves with lower 60 ft times the more volumn you need. & the psi must not drop below 2 psi 2ft off the starting line. if so right when you shift to second the carb. fuel bowl will be empty.It will not fill back up to full until you shift to third & the g force drops off. To check this you must have a computor to monator the fuel system .you can't fell it in the seat of the pants or try to watch a guage on the hood . The
guage will not drop in 1/8 of a second , so you won't know you have no psi or flow & a 1/8 of a second off the line will empty the bowl at the 1-2 shift. So over kill the fuel system. this year at Indy. my fuel wood drop down to 1psi 1/16 of a second off the line.The pump was going bad , run a 10:61 @123mph saw it on the computor changed the pump next run 2.3 psi 1/16 sec. off the line same 60 ft time ran a 10:57 @124.09
I could not fill nothing in the car . I have seen this more than once. ------------------

Steve'66, I don't have an exact weight on my car. The scale has been broke at the track for years. I'm guessing it is close to 3500 track weight, I have 75# ballast next to the bumper. I need to weigh it at a grain mill or a truck scale or even the dump! I would love to get my car to hook and wheelie like Mels! The best I could do last year was about a 6" wheelie, most times it just barely lifts the driver side. I plan on tweeking the front suspension and Caltracs some more. Hopefully they'll make some improvements at the track next spring!
