0-100MPH

Postby jeffw » Sun Jun 09, 2013 9:11 pm

Been playing with the datalogging from Abingdon sprint at the weekend. So on cold tyres on old concrete therefore not the best surface plus me trying not to break driveshafts.

10mph 1.01secs
20mph 1.67secs
30mph 2.23secs
40mph 2.77secs
50mph 3.89secs
60mph 4.57secs
70mph 5.24secs
80mph 6.68secs
90mph 7.54secs
100mph 8.29secs

0-100mph is done in just over 200metres. Maximum of 0.95G under acceleration. 2 gear changes of .7secs each. With warm tyres and better surface I think it would be in the 7secs mark to 100. The limiting factor now is the speed of the gearchanges (H pattern synchro type 9) and I'm getting beaten by cars with sequential changes with WOT shift. I reckon that a sequential box would have saved .8-1.0 secs to 100.

0-100metres was 5.66dsecs at 74.7mph
0-200m was 8.25secs at 99.2mph

Not bad for an English Axle lol....

HI Jeff,
I have turned into data hell. I have not worked out how to read it all yet but if I am correct this is my comparison to your times for you.

10mph .07secs
20mph 1.00secs
30mph 1.06secs
40mph 2.2secs
50mph 2.8secs
60mph 3.4secs
70mph 4.6secs
80mph 7.2secs
90mph 7.9secs
100mph 9.1secs

Maximum of 1.83G under acceleration.

From looking at my past times I am from 7-10 seconds quicker than the striker and can now see where it comes from.

What is really interesting is that by 80MPH I've hauled you in and am going faster and I get to 100 0.8secs faster, what happened between 70 and 80 as you seem to have stopped !. Your 0-60 time is something else though....

I might not have got the last readings correct but I am running a lot of wing and should have turned it down? not sure but it does take longer to get to maximum speed as your car (and my old one) would just keep pulling all the way. it has been very interesting to compare times and see where i can improve.

I wonder if I all the wings came in at that point and started to add the downforce?

Big difference on the 70-80 increment compared with the others. Interesting stuff though....I wouldn't imagine you where that much faster to 70 for me to overtake you (time wise) to 100.

Jeff and Rob I have the printed version which I could scan and email if you wanted it. The print is a bit small so may not come out too well? Don't think I have your email Jeff so send me a PM if you want scans.

Simon/Rob

I have emailed the Abingdon time sheets. Tried to get decent resolution which meant files too large to send all in one go. Hope you can read them OK.
