.

I have been racing since '81, stopped counting at 4000 pass'. I don't know or care what anybody says, I've seen it.
I didn't come here to insult Ed, don't know who he is or what he supposedly knows.
I just happen to have a giant stack of slips on my desk. I ran the top 20, not one was 1-1. On ave. it was .10=.13.
I have had my slow car since '82, 1st pass 16.92, best pass, 8.57. I think I know my cars.
As I said, every combo is different & nothing is cut in stone. The .1=.15 or .2 is just a generalization,
as is the 100 lbs = .10, every step in gear = 300 rpm ect ect. Everybody knows it gets tougher the quicker you go.
Trust me I didn't spend what I spent for a carbon fiber car, for no reason.
Good luck everyone, and the only way to know for sure is everyone will have to check their tickets.

No sanctioning body, no class, just a lot of passes for fun. Oh well, I tried!

FWIW, I'm not argueing, just trying to understand!

Changing the starting line RPM is a little different than a chassis adjustments. That changes your converter's torque multiplication. That will effect the car past 60'. If I raise my starting line RPM from 3200 (slick track, usually 1.35 or so) to 4000 (killer track, 1.30 to 1.32 normally) mine will pick up a couple hundredths more than the change in 60'. Tires, shocks, travel limiters, etc, it will change exactly the difference in 60'. I have watched Mike's pro Stocker a lot also, even being a 1400 hp 2350# stick car it will vary same as 60'.

I would be interested in hearing somebody's explanation about how they can gain more. Seeing a car do that only means somebody's car need work. It's not repeating down track. I've been racing since 1960.

Plain and simple, cars have gained more of a reduction than 1:1 from 60ft to 1/4 ET. Do we really need to drag this out. I can post time slips with the same mph same car same day with nothing but a 60ft reduction and it went faster more than 1:1 in ET.

Dang it, I didnt consider using the multiplication to throw everything off. Bad example on my part. I do see where your coming from though. On a race car that is dialed in based on its repeatable 60' and every other aspect to a finite degree, a small change in 60' time wouldn't change the big end outcome from its normal repeatable range either. But I still like it as a general rule for the general public with a "normal" car

Give up, I have, we obviously can't read or do basic math.
I know I'm not smart enough to explain or figure out how momentum works.

Since it is obvious we were wrong and delusional and it's been proven by a source that can't be argued with or proven wrong, "no greater gain than 1:1 60ft to 1/4 ET can be done", then we should just the thread and make it a sticky.

Who is the genius that wants to put his name on that indisputable fact

I had no intention of coming back here, but when you're wrong, you're wrong.
So I'm here to admit I was wrong. I looked over some records & you know it's true.
When Mike Edwards was running 7.60's his 60' was 1.90's. Now he runs 6.60's & his 60' is .90's.
Amazing he picked up exactly 1 second from his 60' & ET. Case closed!!

Pro Stock gains in the past few years have not been in 60'. Mike went .887 & .888 four years ago that I know of. NHRA Pro Stock average 60's have been between .90 and 1.1, depending on the track and weather, for nearly five years.

What class does that car of your run, anyway?

maybe I'm not allowed to talk here at all, cause we don't even have any tracks here inmy country, but in my vision it's quite simple:
you got .1 better 60ft, means:
you were accelerating faster, means:
by 60ft you have greater mph, means:
you will cover rest of the distance a bit faster too, means:
you will have gained more than .1s in 1/4

Am I very wrong?

Not really (very wrong). .1 for .1, minimum. The way you see it is LOGIC and makes perfect sense .. if applied in a perfect world. BUT, cars and race tracks have variables (we all know this). Race cars are for more predictable than street cars .. so are the drivers (make sure you have those on your "variables" list too). If your tires are spinning at any point, it's near impossible to say exactly what your mph/ET WOULD have been. One could always take an educated guess and come up pretty close though.
