In a previous thread you said the car ran 107MPH.... Which is it 101 MPH or 107 MPH?

That was a one time thing. Never happened again. Turned a lot of 101's.

Some times you get a funky MPH on drag time slips.
I remember a long time ago my friend got a 130MPH on hs 12sec car once.
It does happen.

But from your numbers the car is wanting to go 113 Mph in the 1/4
but something is killing it.
What about the 1/8th mile data? what is the variance in the 1/8th MPH?
88.83MPH is a good 1/8th mile MPH (its at least in the program)
The car starts out well but flattens out at some point about 1/2 way down.

101 MPH sucks for that car. (there is a problem)

any 1000ft data? All this stuff can be analyzed. You definatly have a top end power robber, to find.
The air fuel ratio needs work. (those carbs suck on a T ram anyway)
(carbs-fuel system, (volume, limitiation))
could be spark scatter/crossfire. (ignition cap ionization, usually from too large plug gap and or too hot a coil, or poor cap/rotor phasing)
could be a fubared transmission or torque converter (no top end MPH)
could be a valvetrain issue.
The mufflers definatly suck- you will see from testing
once you find the other cork(s).

Your car should be running like a raped ape, but its got a problem.

Can you post the complete data from some time slips?

not fer nothing.. but could you all be barking up the wrong tree..
the one lonely 107mph is telling me.. it might not be intake/fuel related, and yes I could be wrong.. as I'm here and his car is there..
but are the valves floating.. just a friendly guess..

Per ur suggestion in another post I used irfanview to scan, resize etc trying to get this pic readable. Sure you can manage it. lol Seems I told a lie, or "misspoke" as the politicians say "lol" as u can see by the time slips. Hoping next year the track can afford some ink for their printer. hee hee Really apprecate your help.

A good suggestion...all these areas need to be looked at.

I cannot read it. Please type in the data.

Hate to be critical guy, but your lack of attention detail is probabily 90% of the cars problem.
Hard to get to the root of the tuning problem when you dance around it and take the long hard route with
"politician spin" (half truths, bad facts, spin on data, etc)

I hope you take this in the constructive manor, it is intended.

One looks like 89.15MPh and 100.33 mph (1000 ft) 107 in the 1/4"
If I 'am reading that right:

This indicates the car is dieing progressively as it goes down the track
starting at or just before trhe 1/8th point and gets progressively worse.
power loss.

Once clear shows you let off the gas before the end.
To get a valid accurate MPH at the strip you must keep your foot on the gas 66 feet after the finish line.
Or you will get a low inacurate MPH.
The MPH tells the horsepower. The track is much like a dyno test but requires consistant driving.
The more time slips the better. Post only your data, not the other lane..

the car has the potential to run 113.32 mph. once corrected and will
run faster and quicker when you get BIGGER better carbs, mufflers etc.
easy 11's @115-117MPH when fixed up.

I've lost a few vavles in the past in cars and motorcycles. Doesn't seem to be any vavle float. Of course if they're not hiting anything. hee hee No really, don't seem to be.

I agree with the inconsistencies. I realized after my last track time that I need to forget about the reaction time and concentrate on being consistent with how I launch, shift etc. You’re right about letting off, did that before I was through the traps. Have only made 9 runs after a 47 year absence so have a lot to learn. My main concern at this time was getting an idea of what needs to be done to get the engine to perform which I have now thanks to the suggestions made by you and the other guys. Oh yes! I know you meant it as constructive.

Very good Stuff. There is a 112Mph in your car.. More with a few upgrades and yup, now you got some good places to look at . it will come around for you. Rome wasn't built in a day.
All my stuff is a work in progress too. Good luck...

a set of 4.88's (with the tall 30" drag radials) will make this car into a complete different animal.
Now you will see how a tunnel rammed Willys can run.
