Typical gains from better 60 ft ?

[Rocket Ron]

Hi guys

Been looking at my old timing slip and am wondering what sort of gains in et I can look forward to when I can get my 60 ft down to a reasonable time.

I have a full weight car with dyno mat etc so its not a light car and to be honest I launch like a bit of a pussy. I have just invested in a new msd set up with two step to help improve my launch

Currently run a best of 13.12 at 101.84 and my 60ft is 1.9. If I can get around a 1.5-6 60ft what can I expect

Regards Ron

12.8/12.7 should be possible

[richie]

1.5x 60ft should give you 12.2-3 ish, theory is that you gain in 60ft is doubled down the track

I'm at 1,9 as well. 2 "equal" runs, one at 2,1 and one at 1,9 resulted in .4 of a second at the end.

Thanks for the feed back

Hoping to get back out later in the year so I can post some real world figures, should be interesting to see what it actually turns out to be

I also have a heavy stock Beetle (2,045 lb with driver) and was consistently running low 13's with a couple 12.8's and 12.9's with 1.75-1.8 sixty-foot times.

This weekend I put it all together for once and ran my all-time best:

60 ft = 1.718 seconds
ET = 12.658 seconds
Top-end speed = 106.44 MPH

I'm also a fairly casual driver: no burnout, M&H DOT 215/65's with 22psi and stage with the e-brake for pre-load on the transmission.

That confirms the theory then, thanks Erlend

be nice to see that run some 12s Ron

I'm trying 

[nicolas]

go Ron! i would like to suggest to make it a bit of a competion and see who would run a 12 first, but so far i am at 13.5 - 13.6 and not much is happening to get the car ready for DDD...


i always asked myself why this is so important? it is but i can't get my head around the idea of one car (a very light bug) with a quick start and good take-off, but maybe lacking power at the top end, compared to a heavy car (a chevy or a even a truck) which would pull off the line slower but catching up at the end of the track. do they have similar 60ft's?

i always think of the race between my heavy fastback and Lee's lightweight buggy at EBI. we finished almost at the same ET, but i was trying to catch him all the way down the track.

Hi Nicholas

Be good to run a 12 and I'm sure I will, unfortunately I won't be back out until the of October due to pressure of work and home life.

I'll be watching you to see your progress 

Hopefully my new two step set up will help my poor driving and i'll get that 12 before the end of the season

Good to catch up at pats and ebi

Regards Ron

OK, just to up the ante, i just cleaned the house and found some paperwork and the timeslips from last year at DDD.

best time was:

13.547 at 98.04MPH
60ft was 1.997


...
so there is lots of room for improvement i guess.  good talking to you as well.

your heavier car has more hp to chase down a lighter car, your mph will be higher at the finish line.

Look at a N/A vw to a turbo vw, the N/A car will typically be lighter and 60ft better, then the torque of the turbo car with usually taller gears will catch up with much higher mph and overtake

yes that is true. the MPH is higher. but if so, 60ft don't tell the whole story? they seem to be 'car-specific'? this is what puzzles me.
BUT i know i'll have to work on my 60ft's as they are too high for a light/NA car. 

[dannyboy]

this weekend was a cracking example of 60ft and headwind/tailwind for my car
i did a 1.46 60ft and went over the line at 129mph with a bit of a cross/tailwind  running a 10.47
then later on the wind came round and i did 1.41 60ft went over the line at 126mph with headwind runnig10.47
all the elements need to be in line for a perfect pass  i reckon put the two together and a low 10.4 or high 10.3 is possible?

A racer once advised me that my slower 60' allowed for higher top-speed (and vice versa)...he mentioned that it is difficult to have your best 60' and best MPH in the same race.

Our experience has been just the opposite Neil.  I happen to have the time slips from 2 races ago in my wallet and just checked them.  Our slowest 60ft was 1.477 and resulted in the slowest miles per hour as well at 121.119 (ET was 10.793).  Our best 60ft that day was a 1.432 and the miles per hour was 123.057 ( ET was 10.756).  We made 6 passes that particular day.  I think in general we have the best ET and MPH when we run the best 60ft on any given day.  Ours is a NA car.

All be at cal drag day and see how much difference a two step ignition makes
