Peak 370 Posted July 23, 2014 Share Posted July 23, 2014 I just put the phone down to a journo in LA who has been speaking with a guy with a 1950s technology Top Fuel Yank V8 racer. No overhead cams. Pushrods. 2 valves per cylinder. 0-335mph in 4.4 seconds! With the first 120mph taking one second! 0-120 in a second? How the heck do those drivers not pass out?

brillomaster Posted July 23, 2014 Share Posted July 23, 2014 120mph is 53.6 metres per second, so to accelerate to that speed in a second is the equivalent of about 5.5G... thats pretty savage acceleration, thankfully it'll only be for a few seconds! 2 Quote Link to comment Share on other sites More sharing options...

Would love to have a go one day but the costs are absolutely out of this world! 1 Quote Link to comment Share on other sites More sharing options...
neo-ninja Posted July 23, 2014 Share Posted July 23, 2014 There used to be a video on youtube of the tests the americans did back in WW2 time (I think) to see how much the human body could take G wise by getting people to accelerate to 600mph+ and then stop instantly. I cant remember the record off by heart by I remember the dude who did it stopped so fast the dust in his suit moved across his skin so fast it caused blisters and burns. Fascinating video if someone can find it. Was history channel or something. 1 Quote Link to comment Share on other sites More sharing options...
brillomaster Posted July 23, 2014 Share Posted July 23, 2014 yeah i remember something like that... rocket propelled sled brought to a controlled stop in water or something. decellerative forces of 47G i seem to remember, detached retinas from eyes or something ludicrous.

Peak 370 Posted July 23, 2014 Author Share Posted July 23, 2014 0-153 in 9.33 is my best ever quarter. Sounds slow now! Quote Link to comment Share on other sites More sharing options...
Daveyboy11 Posted July 24, 2014 Share Posted July 24, 2014 0-153 in 9.33 is my best ever quarter. Sounds slow now! 9 seconds is far from slow!! My dad used to run a methanol dragster in Super Pro and that was running 7's at about 200mph. 1 Quote Link to comment Share on other sites More sharing options...
coldel Posted July 24, 2014 Share Posted July 24, 2014 Although slightly cheating, watching the jet cars clear quarter mile in 3 seconds at Santa Pod was pretty impressive. Although as a ten year old didnt appreciate what the driver was going through at the time! 1 Quote Link to comment Share on other sites More sharing options...

The jet car has never made a 3 second pass, but Sammy Millers rocket car certainly did! 1 Quote Link to comment Share on other sites More sharing options...

docwra Posted July 24, 2014 Share Posted July 24, 2014 Stupid man in a rocket sled, starts about 0.50 "When he began his research in 1947, the aerospace conventional wisdom was that a man would suffer fatally around 18 g. Stapp shattered this barrier in the process of his progressive work, experiencing more "peak" g-forces voluntarily than any other human. Stapp suffered repeated and various injuries including broken limbs, ribs,detached retina, and miscellaneous traumas which eventually resulted in lifelong lingering vision problems caused by permanently burst blood vessels in his eyes. In one of his final rocket-propelled rides, Stapp was subjected to 46.2 times the force of gravity.[5] The aeronautical design changes this fundamental research wrought are widespread and hard to quantify, but fundamentally important."

Peak 370 Posted July 24, 2014 Author Share Posted July 24, 2014 To get the power down to tyres and get to 330+ in 440 yards is incredible. But it's the first second that really amazes. You'd think getting away would be toughest. I often wonder what they could do without the 100+ regulations. Engine size, blower size, tyre size, etc. Quote Link to comment Share on other sites More sharing options...
Daveyboy11 Posted July 24, 2014 Share Posted July 24, 2014 Yeah they are just incredible but I feel like they are getting to a point where they can't improve anymore, the cars/tracks just can't take it and half of them either lite the tyres up or detonate half way down the track. 1 Quote Link to comment Share on other sites More sharing options...
Peak 370 Posted July 24, 2014 Author Share Posted July 24, 2014 Many of the restrictions do harm times though. A bigger engine might be able to run lower boost, etc. Wider wheels may well help traction. Intake size, etc., are restricted. I was amazed at how many rules there are. 1 Quote Link to comment Share on other sites More sharing options...
