[EVDL] DSS Electric Junior Dragster - Initial Testing!!!
Hello all, It's been a long road but we are almost at the finish line. Pardon the pun. Hopefully we will be out with the other high schools at the track on June 28th. Enjoy the video! :) https://www.youtube.com/watch?v=sW1EEa0G5pM Casey -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/DSS-Electric-Junior-Dragster-Initial-Testing-tp4687095.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
Re: [EVDL] Shock and Awe - Historic run 9.589 Seconds @ 152 MPH!!!
Hi Tom! It's a fantastic project only possible by copious amounts of money! This team and their instructor (Pat Mccue) have literally been working around the clock for the last two years to see this moment come to fruition. And, it_is_amazing! The tires were at 6.5psi with bead locks. No_expense has been avoided in regards to this car being a full on drag racer with top of the line parts. Period. The tires were also measured after each run for their circumference. The Northshore Automotive Technology team has big racing names supporting them. A long list of mentors include Hancock and Lane racing. If you look up their history, the High School race team from Bothell is learning from the top echelon of drag racing teams. Very, very exciting to watch in person! :) http://hancockandlane.com/ Cheers!

Re: [EVDL] Dead accessory battery (was: Shock and Awe - Historic run 9.589 Seconds @ 152 MPH!!!)
Hey Bill! I appreciate you commenting! Your knowledge and experience in racing (and many other ventures) is well known and respected! Yes, Pat Mccue and the team are running 800 volts (Dual Reinhart controllers and dual AM Racing motors) and I think (he would have to chime in) that running a DC-DC converter complicated the setup so they opted for an isolated 16v battery. The headway pack (16v accessory battery) they made had seen it's day and was not as healthy as it could have been. They did have a lithium specific charger for the headway pack. So, off to the local parts supplier for a regular old heavy 16 volt racing AGM. Apparently for racing they opt for a 16v battery as due to the heavy loads and ignition systems. I did not know this and learned helping out in the pits. Always something new to know! :) The car is drawing about 40 amps to run all the accessories and pumps. So, it's quite the draw. The team was being pretty careful to charge the 16 volt battery between runs and shutting the battery off while sitting in the staging lanes. It just happened at that point in the day it got lost in the mix. Also, they had not planned on putting in an AGM so did not bring a 16 volt racing charger. Like I mentioned in the pits, well, that's racing! :) The back of the car near the '12v' shut off is an analog style voltage gauge. So, it's pretty easy to see what the 16v accessory battery is doing under changing and draw. Also, it's disconnected from the car when not running. The team has done an amazing job engineering the vehicle. It's quite stunning. Like you mention, this event is something we all go through. I remember with our schools drag truck we had the same problem running a pc680 as our accessory battery and making sure it was topped up after every run. There's nothing more humbling and rewarding than learning from a lived experience! :) Cheers!

[EVDL] Shock and Awe - Historic run 9.589 Seconds @ 152 MPH!!!
Hey all! A historic day for the Shock and Awe racing team from Bothell Washington and the world of drag racing! After sitting in gridlock and sweltering heat on the #1 towards Mission Raceway, I arrived just as the track was doing lunch. All in all it was an amazing day with some serious excitement (a 9.589 second 152 MPH run) and a bit of a turn at the end of the day. During run #2 the 16 volt AGM (which was changed out for a faltering 16v lithium pack of headway cells) ran out just as the team was pulling up to the line. So, yesterday ended in a somber moment of reflection. A good reminder, racing is a tough sport, physically, mentally, emotionally, financially, all of the above! The team is at the track today hoping to get in another run, depending on how that goes possibly a second. For now, enjoy the video! :) https://www.youtube.com/watch?v=L53JTDnmj_w Cheers!
