Well great...

Shawn, I got my Stinger running a few weeks back. I put on a dual bypass older Black Widow cylinder. My thought was that this would use fuel at a higher rate. The tanks are quite small and I was looking for a shorter run. It sent the rpm's into oblivion. Not a good choice and I will be going back to the single ported cylinder. There just is no need for that high of rpm. It still ran too long. The main problem I had was keeping the line taught. The car went down the line sliding from left to right. Maybe a little lead in the body will prevent that. I seriously feel that the wheels were spinning on the ground rather than hooking up. You really need to keep a lot of sponges and such at the end of the line due to the car hitting the pin in which it just sits there doing a burnout. You need a lot of line length.

As for the bladder, not a good choice for a car. One it's not needed as the tank draws fuel just fine. When a bladder gets to the end of the run, the engine goes rich unlike a tank which goes lean. In order for the bladder to work properly it would need to be filled adequately to reap the benefit of pressure . That would be far too much fuel. However, running a 128TPI needle in the dragster gives you a much finer and leaner setting than the stock needle therefore extracting a bit more power. As for your Stinger, if you decide to run it, be very careful of the rear wheels. The wheels have hex's molded on the inside. This is what drives them and they split at the intersection of each flat. If you can find the rear wheel set from a Eliminator or Vega, these have a different plastic which is more durable almost like a reinforced plastic and last a long time. Ken

Might be a good idea at the finish-line, (along with the sponge-bumpers) to use a thin sheet of smooth plastic about 2 feet square.. and drill a hole centered on the far edge for the pin to go through. When the car reaches the finish line, the drive tires will spin on smooth plastic.. rather than abrasive pavement or having excess dirt/debris thrown up into the chassis/engine. Having the pin go through the sheet, prevents it from being kicked-back by the spinning drive-tires when the car stops.

Thanks Ken and Roddie for the suggestions. I think I'll use the stock fuel tank instead. Also, I have 2 Stingers, one is new with the  Eliminator style drive train and slicks. The other one is used and may have been a prototype or test car as the right rear wheel is driven and the left rear wheel has no hex molded into it and just spins free. Also the body hold down on the rear of the chassis looks to have been molded differently as well. Since it has already been used and I got it dirt cheap, I plan on running it instead of the new one.

Oh hey Ken, do you have any video of the Stinger?

This is from the manual of an old Corvette, shows a way to slow the car at the end of the run.

Shawn, I still have no video. Our club Facebook designer Rich Martinez has mentioned many of times for us to drag out all of our Cox related items. Our club has one heck of a collection when put together. Rich is responsible for all video on our Facebook page so without him were all lost. This could happen within the next month or so. I will talk to the club into taking part of this as this could really be quite cool. Ken

When I was a kid, my friends and I used a setup almost identical to that for our funny cars except we used a longer and wider V lines. We also had a couple people at the end to grab the car(s) and shut the engine(s) off in case a parachute didn't deploy or if they didn't run out of fuel in time.

That would be neat to see.
