 Before sending my cars off to a Proxy race, is it better to remove the traction mags - when allowed, not knowing the track. As a rule do cars run better times with or without the traction mags? Thanks

Before sending my cars off to a Proxy race, is it better to remove the traction mags - when allowed, not knowing the track. As a rule do cars run better times with or without the traction mags? Thanks Some cars do run faster time with one magent instead of two. My AW 4 gears all run better with one magnet. Depending on the voltage run, traction magnets are a must. Case in point. If you run a highly modified car with low ohm arm and braids and shunts with silicone foam tires at say 13 volts the car should hook up. Bump up the voltage to 20 or 25 and you will always deslot if you do not have traction magnets. If the class allows traction magnets, ship the car with the magnets. Don't be to concerned with rail hight. If your cars clear the rails on a piece of test track you should be ok on most other tracks. I test traction magnet clearence with a piece of Tomy track and never had a problem. Cutting to the chase, these guys on this forum have got the set up for each class pretty much dialed in. Just follow the rules for a specific class and you should be ok. |

Kbuck, think your looking at a similar situation as the w/bars. If you need the magnets because of wheel spin use them. I think most here use "rare earth" dot magnets from Radio Shack on t-jets or even the one mag that's been removed from the 4g works. But if the mags are not needed they just put strain on the drive train. Just for example, I've been working on 4g's and did a type A build (NTRA), did it with a NOS chassis no traction magnets. The poly motor mags exert enough force on track rails for traction. And that's with a 5 ohm arm. The cars I told you about being the same and one needing bars the other not are 14 ohm arms. Each of those have one traction mag on them. Don't know if you caught the thread Drag builder Competion, but it is recomended that only one traction magnet be used. The cars run were 5ohm poly t-jets. Cars will hook up different on different tracks, to be on the safe side one traction magnet where allowed is what I use. The 4g with the polys is an exception, .....well maybe. All this talking has left me with a dilema. Good luck at the race!

Ok, I've got a 4 gear 55 chevy with hood scoop and chute. Does this qualify as a door slammer or a gasser or both? The rules seem a little unclear.

I believe it would fall into the doorslammer group because it is on a four gear chassis. Gassers are on tjet based chassis.

There is nothing in the Door Slammer rules that would prohibit that body from being used. If it is a factory made body and you are using a matching chassis, it could also be used for 4G Stock providing the chassis meets the 4G Stock rules. Hope this helps. |

I was testing some cars this morning and have come to the conclusion, that the four gear cars are no where as quick as the T-JET 500. Or is it possible that everyone of my 4 gear cars are just bad? Has anyone else noticed this?

Hey Kbuck I bought about 13 nhra 4 gear cars and 10 of them were real slow then i read the 4 gear tips and tricks on here plus tightend up rear top gear on the back where the rivet is and they all run better now.

Kbuck, the 4g t&t will help to get things moving. Onefastmustang, mentioned the rear gear on top plate. If you rotate rear wheel back and forth or clockwise and counter clockwise about and eight of a turn each direction you will see the top cluster gear jump all around if you have a bad problem with that gear. I've found that the 4g's are gear challenged (is that politicaly correct), have even had casses where large idler would bind up whole train because whole in gear was smaller than post on plate. More time spent on gears will all ways help a 4g.

Ok, thanks for the help. The top gear does move alot. what is the best way to tighten up the slop? I am about ready to give up on these four gear cars and stick with the new TJ-500's. They always seem to run allot quicker.

Not sure what best way is to tighten up the cluster gears. Haven't done one yet. But something to flair the end of the rivet and tighten gear assem. Maybe a gear press could work. A vise rigged with a post for top of rivet might do. I'll probably find something to rest top of rivet on and use a nail set and hammer. Whatever you decide be carefull, to much might not be easy to undo.
