Index Cars

The car setup is basically the same for both cars, although for 1.000 I use a 12, and for 1.200, I use a S-16D.

15/44 gears, 1.00x.435 wide tires, and approximately 120 gram car. The weight is what I use to hone it in on the index, so that is a variable. These cars take virtually no glue. Clean the glue off the tires from the shutdown, clean the track, and roll the car out on the starting line. The thin film there should be enough to hold it. It may even be too much!

This is for a Lexan bodied car with a sidewinder motor location.

Good Luck!!!

Re: Index Cars

Simple question,take and make a consintant running package ,then add lead in small amounts to fine tune the time. would you want the time to be slightly higher than the index for us with dead slow reaction time,or a liitle slower as not to break out. I've never raced an Index car or event so am wondering ?

Re: Index Cars

LApromods,they run a 10.90 Index at T.S.S. which I am trying to build for my comp eliminator car was a little fast for this Index so I decided to pull the weight  out and start over. It's a WRP tall tire chassis .072 stainless tubing , Pro Track tires 1 3/16 X .350 wide edges rounded , factory blue printed ProSlot S16D  , 12 th x 56 th sonic gears and a 68 mustang hard body, all up about 115 grams and depending on the track runs about 10.60 to 10.30(could go for 10.00) which if I can learn to pedal would work for 10.90 , I added 14 grams of weight just behind the pick-up guide and it turned a 10.99 and a 10.97 in practice, I will shave just a sliver off as the test track is a few tenths faster. I'm just starting this Index thing also,but found out it is almost as fun as brackets ,and a steady Index car makes a great bracket car!

Re: Index Cars

Just got around to reading this post, Steve, parallel wiring won't do as you say unless there are seperate power supplies for each lane.


I know more than I will ever admit to

Re: Index Cars

David,
I race index a bunch and I prefer to run .001-.015 slower than my index.  If you have a good light the other racer may stay in it and breakout, if you have a bad light he still may break out because most of the racers have cars that are faster than the index.  I have won many races with a .010 off run.  I put faith in my car and run it out the backdoor, lol.

Re: Index Cars

My favorite 1.200 cars are a Nova, and a Mustang.

The mustang and nova both have inline chassis...The Nova is a parma deathstar motor geared 14-46 with pro track TA500 1.01X.300 wide tires. It weighs 120 grams, and runs 1.200s on the nose out the back door. Its a killer car, and if i dont have time to time shot bracket cars i can fall back on either one of these cars anytime.

The mustang is a Speed FX S16D, its geared 16-52 with speed secret 1 3/16x.300s. It was built by "8" out of Cali, and im sure it was build by him as a 1.200 car..It takes Very little glue and is also a killer bracket car. Im guessing it weighs around 130 grams.

Im wanting to build a 160gram pro mod looking car with a single magnet Grp20 to run 1.200, just for fun .

As for 1.000, ill take a pro slot D-Can with a american arm in a inline chassis with 1 1/16x.500 geared about 13-58 in a 120gram car

Re: Index Cars

I stumbled on a motor that so far is working good for a 10.90 car. I put a x-12 arm in an Parma D can,no  magnet shims just adjusted the armature play and closed it up, bolted into a WRP tall tire inline and a lexan body and so far is a consistand 10.73 to 10.78 geared at 10/50, protrack 1 1/16 X .300 ,with a Parma S16D it was only getting low 13's

Re: Index Cars

Same Combo in my 69 camaro 125g runs same times, my gear is a little different, I think you could go faster with an 11t, but I know you are trying to get 10.90.  Maybe go for .990? eh? nudge nudge, lol.
David I love those 12's in 16ds for bracket motors!  Soft launch and big mph.
Are you going to try for the slower side of 10.90 or stay where you are?

Timmy!

Re: Index Cars

Timmy ,I'm trying a experiment(as usual ) Edge chassis, bushings ,extra bracing in motor box an whellie bar areas , Pro Slot Big Block 20 , 12-54 gearing with 1 3/16 X .435 WRP tires ,hard body 66 GTO. see if it will run in the .990 range. will most likely will have to work the gear ratio a little  the 10.90 Mustang has fallen off , but the lexan with the 16d can x -12 arm is a little faster than 10.90 so I guess I learn to pedal.

Re: Index Cars

going to run it tonight,let you know if it gets back! using my new model airplane fuel tubing body mounting either it will work or that body will be toast! works good on slower ,less powerfull cars but never tried it on anything faster than 35Mph.     Well an interesting night ,the body mounts held up, needed a lot tighter wheelie bar adjustment. The first pass the pinion force pushed the wheel back and it coasted to a 1.056, I even had flats on the axle! so I re-tightened and adjusted everything, run another pass 1.033 entered it with a 1.000 dial won the round with a 1.300 , next the opponite red light and I turned a 1.024 off a 1.010 dial , next a win with a 1.022 0n a 1.020 dial , then it broke out with a 1.015 0n the 1.020 dial , it didn't make the .999 yet but I feel it's there! will lighten the edge chassis a little, narrow the tires a touch, the 60 ft times were slower than I expected so I may change the tire diamater by haveing them turned down a hair from 1 3/16 but I wouldn't be afraid to enter it in a .990 index the way it is , oh I tried a slow roll out with my Parma 3 Ohm turbo and cooked the low band right off the wet wound resistor.....not a 16D!

Re: Index Cars

Sounds like you did a Great job David!
I want to see the new body mounts you have me interested.
You can resloder the resistor wire at the break and reuse it.

a speed fx and 15/52 or 54 should get you in the 1.050's on a 120 gram car you can gear up or down to get you where you want to be..... i use this combo often for my bracket cars.. if I want to go faster then I hit it with some golddust brushes and champion lite springs and if i need to go slower i turn the dial down some on the stealth,

1.190 cars I use JK hawk 7 motor with 15/46 this will get you mid 11's but if your heavy then you will be right in the box but these motors roll so lifting will be alot sooner than a S16D..  I use my stealth to turn down

Re: Index Cars

good 990 setup is .550 BB arm in a Parma EXP 499 setup..... will run mid 9's take some gear out!!!

Re: Index Cars

I have two falcon 7 setups that run 1190s 1200s both are around 125 grams, c-06 and c-10 chassis, both 1 3/16 tires 500 wide, thinking gearing is 12/54 and 12/52...

lightfighter, whats your weight on that BB arm in 499 can??

120 grams  just putting the arm in... mid 9's balanced arm is 9ohs  I have one I BB'd the can, balanced the arm and shunted  I went .850 in 120 gram car at 67mph not bad for a 40 dollar setup!!!

hawk 7 I geared at 15/46 goes mid 11's  great 1190 car!!

Re: Index Cars

whats the gearing on the bb/499 setup??

 

12/02/2010 5:52 am  #18


Re: Index Cars

Thats just what the first one I had was geared and so I geared the rest the same since it was so consistent, it may be possible... I think the styrene cars are suppose to be run mid tens those are 16/46 or something like that...

clownsRus, I guess getting Falcons with hard bodies to run under 1 second for the 1/4 mile is out of the question?  I was just hoping.  I did notice you are geared pretty high at 12/54 and 12/52 considering JK suggest gearing them 3/1?

I think you can get the JK hawk 7 to run under 1. if you can get it out the hole...... those come with Neo mags in them.... i just can't get them to hook real good at full power launch!!!

Bill, how do you figure out what the suggested ratio is for certain motors? just curious...

Ok, so I looked and I was off, my camaro is 13-48 and my nova is 13-50, they do both run low 1200s and are around 120-125 grams... but I have problems with my nova wanting to spin also but the camaro doesn't, same size tires too, can't figure it out, I think I'm going to change one of them to 15/45 tonight and see how it does this weekend...

Re: Index Cars

I'm gonna step up the power to a 16/46  kill the crazy launch and get some more HP on the top end

JK hawk 7  smooth  and smooth is fast!!!!

Re: Index Cars

The 15 tooth gear is the pinion, and the 44 tooth the ring gear. They are for a sidewinder setup, not for an in-line.
