Woodburn Nationals 2004
I just thought it would be good to let you all know the full story of "Gone
Postal" at Woodburn.
The new front axles were installed a couple of weeks
or so back and there wasn't any nearby tracks open before Woodburn so
"Gone Postal" had sat in the shop for about two months with the batteries
charged as delivered by Rich after he was done testing and taking it to the
Greenwood Car Show in Seattle and a parade in Kingston.
I knew the first run wouldn't be great as the batteries were cold and hadn't been cycled so
I figured I would take a run down the track to warm them and fill em up.
Also the rear drive according to Rich was turned down to 1300 amps. That's
like in Raptor territory, not Zilla numbers. Also Oat had suggested we try
a third gear launch instead of second and I wanted to test his theory and
see if we got a better 60 foot time than our previous best of 1.89
seconds. I pulled up "Gone Postal" into the bleach box with the front wheels
and did a burnoff in second to warm the front tires due to the traction
problems we've been experiencing on the front. I did a smokey burnoff going
a bit sideways but corrected as I approached the timing lights. I put it in
third for the launch and when the lights came down I put the aluminum to the
floor and the launch felt great.
We did the sixty foot in 2.154 seconds and
we crossed the eighth at near 80 mph, 0 to 79.85 in 8.861 seconds to be
exact. Not too bad for a two ton plus block of lead. As Bill Dube says
we're fighting that old cube law. Bill has told me: " The HP requirement to
overcome the aero drag is the cube of the velocity. You also must toss in a
"square law" to accelerate the vehicle to the end velocity." He has told me
it might not be impossible but it would be very difficult to accelerate
this brick to over 100 mph in the quarter. I agree with Bill on this and I
know it is not any easy task but I bit it off knowing this. I thought the
accomplishment would be more significant in the minds of John Q. Public. I
want old John Q. to think that he has a much better idea than me and that
he could go out and build himself a light weight aerodynamic vehicle and
kick my ass. Of course this is the psychological motivation for doing it
the hard way.
Well, back to the track, right around the eighth mile I shift
into fifth gear and also right about then the built in series/parallel
function of the Zilla's "Hairball" kicks in and I have to hold on as the
electric nitrous slams be back in the seat. Well I kept waiting and waiting
and nothing happened. We crossed the line on our first cold run at 14.007
seconds at 92.91 mph knocking almost two seconds from our previous world
record in MP/B of 15.907 seconds at 90.66 mph set at Las Vegas. I went back
to the pits and was somewhat perturbed by the series/parallel not
functioning. I did some inquiries and found that one of our crewmembers who
shall remain nameless had rewired "Gone Postal" without my permission or
knowledge and had disabled the series/parallel function from automatic to
manual and had installed a switch that I was not informed off. I was a bit
ticked off to say the least. I wanted to turn the rear drives up to the
full 2000 amps for the next run but was unable to get this accomplished
because the same crewmember who is in charge of programming spaced out
bringing his lap top. Well I was all charged up and it was the electrics
turn to run again so I said what the heck, I'll just use the manual switch
which won't be as effective as the "Hairball" computer that Otmar has
programmed to switch at just the right moment. I did another smokey burnoff
in second then shifted to third for the launch. I launched very hard mostly
due to warm batteries. It must have been only about thirty feet out judging
from my 3.374 sixty foot time when I heard a horrible noise as I lost
power. There was major crunching sounds coming from the Corrado transaxle.
I realized I was done racing for the day. As I was coasting to a stop some
weird force overtook me and I said to myself what the heck and shoved the
tranny into fourth gear and nailed it. As I shifted into fifth I remembered
the series/parallel switch and hit it. I crossed the line at 98 mph flat at
18.324 seconds.
Some things to ponder. In the first run without the
series/parallel mode I accelerated from 79.85 mph at the eighth to 92.91
mph in 5.146 seconds with a gain of 13.06 mph. With series parallel in the
second run I accelerated from 73.08 mph in the eight to 98 mph in 5.101
seconds with a gain of 24.92 mph. Looking at these numbers shows that in
about the same amount of time I almost double my mph on the far end using
series/parallel. You all can be the judge of how far away "Gone Postal" is
from breaking 100 mph in the quarter.
I am really looking forward to the
2005 racing series. The NEDRA board will be working on the new season
schedule starting tomorrow. There's going to be a lot of competition and
excitement this upcoming year with many improvements in your NEDRA
organization. I look forward to seeing you all soon.
