5.33 in a 1/8,what should a 1/4 be?????

[oldhead]

Hi...I was a Atco Raceway on thursday night and my 4th run was 5.62/125.71 in the 1/8 and 8.75/156.21 in the 1/4...I turned the power up about 40hp. and went for the 5th run. I missed shifting into OD (Gearvendors) at 1000 ft. and coasted thru...5.53/128.73 in the 1/8, and 8.76/141.40....can anyone give me a 1/4 mile et.& mph. guess....OH can you tell me why my ladder bar Malibu rides so hard driving it to the track and after it goes in the 8's, then it rides like a Caddy on the way home OLDHEAD

5.33 1/8 = 8.3681 1/4, (It's late and I am tired so should be pretty close). Your ladder bar setup rides hard because it binds on all turns. You must drive straight home!

My guess 8.57 @ 160


Cobra, he wrote 5.53 in the post, not 5.33 like in the title.

Sorry for the mistake,Thanks John,5.53 is correct...... OLDHEAD

John, I am very aware of what was written in post. He asked for 5.33 so that is what he got. Oldhead, let us know how this car runs on its next strip outing. For the 5.53 1/8 to 1/4 number you would be at 8.6821.

[oldhead]

Well I didn't want to confuse the question but I guess I have to tell all....The last run was with the OD never turned off from the run before....so what happened on the run in question is the od shifts into od at 20 mph(about 15ft.) so my 60 ft. was a 1.32 instead of 1.29 in the run before...and at 1000 ft. instead of going into OD. I shifted out....And I was thinking about 8.60 at 159................. OLDHEAD

your 5.530 ET at 128.73

60= 1.2060 53.9866
330= 3.5410 99.6060
660= 5.5300 128.7272
1000= 7.0676 149.4317
1320= 8.5644 142.4624
Tire Friction Coeff= 2.1254

------ Front Tire ------
RollOut Distance Data
Ft ET MPH GForce
-1 -0.1710 0.0000 0.0000
0 0.0000 7.9736 2.1254

so it looks like you hit Brakes slightly to run
8.76/141.40 at 1/4 mile ???


5.53 1/8 mile should be around a 8.67 ET - 157 MPH 1/4 mile

Go to Page 3 at:

and adjust the horsepower input until you've matched your speed. (Don't worry about ET. This is affected by variables too numerous to "capture" accurately in any software package.) Then, go to Page 2 and you can play with gearing for the quarter and see the effect.

That's a bunch of very useful Calculators on your Website !

i'll have to try them all out !
