Easy Steps to build a Pony or F.W.D. Pure Stock

Information Contributed by : Torg Motorsports

 

 

---------------------------------------------------------------------

-----------

 

 

Find a suitable car. It's best to purchase your first racecar already put together. But if you decide to build one, here are some tips. Watch the races and see what the fast guys are driving, chances are they have already researched different makes and models and are racing a style of car for a reason. Experience suggests GM and Chrysler are the best cars to race with because the front suspension of both of them is adjustable for camber and the entire front suspension is mounted on a cradle. Being on a cradle allows you to replace it if you bend it.

 

You should look to spend a small amount of money on a car because you will be removing everything out of it. Look for a car that has been taken care of and not rusted out. A rusted car will take a lot of repair before being able to weld in a roll cage. Be sure to look under the car and check for rust. Most cars have some rust, you just don't want one that has rust HOLES.

 

Interior/Roll Cage

Ok so now you picked out a car. Remove the entire interior, you don't want to leave anything that could catch fire when you start welding. If you want to leave the dash and shifter that's OK. Also remove all glass, the windshield is optional.

 

As for the roll cage. Now is the time to find some help. If you're not an experienced welder you should find one. After all your very life may depend on how well the roll cage is welded together. There are many local people that would be willing to install a cage for you. Check with the race track as many of the racers are willing to do this. When finding a company to install the cage ask if they will be bending the tube or buying a kit form. Bending the tube will result in a better fit, but buying a kit is sometimes cheaper.

 

Racing Seat

Once the car has a cage you can purchase a racing seat and safety equipment. The rules will only allow aluminum seats. Normally there are lots of used seats available you just have to look around. Be sure to buy a seat that fits snug and holds you well. Snug is better. When mounting the seat be sure to use at least 3/8 bolts, grade 8. A little work here will pay off really well. You should use four to six bolts to hold the seat down.

 

Belts

The rules call for a five point, three inch wide belt. RCI and G force make some really good belt systems that are reasonably priced. Don't buy used belts, as all belts are dated and must be replaced every 3 years.

 

Engine

Do a tune up on the engine and check the compression. The compression should be 125+ psi and no cylinder should be less than 100psi. Change all the fluids; drain the antifreeze replace with water. Replace the engine accessory drive belts. It is also a good idea to change the oil and filter in the transmission.

 

Fuel Cell

You should run a fuel cell, I know some tracks say you don't need one but it's not really that costly and will help you out in the long run. Running a stock tank is not a good idea because you will have to keep a lot more fuel in the car. Stock gas tanks are not designed to keep the fuel in place during a night of racing. There is no foam in the stock tank and the fuel will slosh around making it hard to keep the right fuel pressure to the engine. If you run a cell you can keep less fuel in the car and the foam will keep it in check to allow the fuel pump to keep a good supply of fuel to the engine. Less fuel equals less weight in the car. When running a fuel cell you will need to run an aftermarket fuel pump. Most of the racers are using the frame mounted fuel pump from an 88-91 Ford truck. Just ask the parts store for a frame mounted external fuel pump for an 89 F-150. The pump runs on 12volts and will pump plenty of fuel.

 

Suspension

Tires are the most important part of any car! Check with the other race teams and find out what tire they are running. Be sure to check and see what's legal. Good tires will make the difference in the way your car handles. Buy a good air pressure gauge, tire pressure is the biggest adjustment you will be making. You should also buy a tire pyrometer. It's a temp gauge that you will use to see how well the tires are working. Tires will be the most used/checked thing on your racecar. You will need to keep a lot of information on your tires. Every time you get to the track check your air pressure before every race and every practice. The air pressure in your tires will change with heat. About 1psi for every 7deg F. You will need to make adjustments that allow for this to happen and not upset the car. So for Example your tires are running at 140°F and it's 80°F outside. (Ex: 140°- 80° = 60° / 7 = 8.5psi)

 

You will need to reduce the air in your tires by 8.5psi to allow the right pressure when racing. Again tires are the most important part of the car. You need to learn as much about them as you can. Keep really good notes and you will have something to fall back on when the track changes.

 

Toe and Camber setting

Toe is the angle that the tires have toward each other. Look down at your feet. If your toes point toward each other then you are toed in. If your toes point away from each other then you are toed out. The same goes for your racecar. If your tires are pointed toward each other then they are toed in and visa versa. You will need to set the toe, and camber on your car every week. Always check it after any contact with other cars. You should set the front toe to 0" to 1/16" OUT. On some cars the rear toe is adjustable, be sure to set it too. In the rear you should run 0" to 1/16" IN. Be sure to check your toe often and learn to adjust it.

 

Camber

Camber is the angle at which the top of the tire is tilted in or out. If you are turning left all the time you should tip the RF tire in at the top. With camber in it allows the tire to stay in contact with the road surface longer and turn the car better. More camber is not always better. This is where you need to check the tires after you run and move the camber and toe until the tires are the same temperature all the way across.

 

In a front wheel drive car most of them are running 2deg out on the left front 7deg in on the right front 1.5 In on the right rear 0 on the left rear.

 

Ok, so now you have a car with a roll cage, seat, belts, fuel cell and the suspension has been set. Buy a good fire suit and a "S" Rated Helmet and Go Racing.

#19 Neon,,,,

 

Glad we here in Michigan helped out a little, How well do the Neons run against Hondas at your track?

 

 

Well, actually, I run (ran) a Honda CRX for the past 2 1/2 years.

 

I am switching to a Toyota for 2007 (or possibly 2008 as the car is still not done yet.) I run with a touring series called the Texas ProSedans and we run only asphalt. But we also have 2 local classes here in South Texas called the Texas Thunders, one runs on dirt, and the other one on asphalt. TPS has not had a Neon in it YET. One of the Hot shoes from the Thunders (who kicked but on both dirt and asphalt) will be joining us this year. I personally expect him to do quite well. AND now that you just gave him all of that information, he will have no excuse not too!! LOL...

 

They call him NeonWill - (cue the music!!)

> Camber ? How much RF, LF, RR, LR. ?

 

It depends on the car and the tires being used. But generally, you want to get as much negative camber in the RF as you can. Note: Negative is when the top of the tire is tilted inward. 6-8 degrees of negative camber generally works well in the RF. About 2-4 degrees of positive camber works in the LF. Maybe 2-4 degrees of negative camber for the RR. Don't worry about the LR since it has little effect on handling. 0 degrees works OK for the LR.

 

How do you increase the camber settings?

 

I am only familiar with how to change the camber on the Mopar cars. Someone else can chime in about the other cars.

 

Near the bottom of the front struts are two large bolts. These are used for adjusting the camber on the front. You can also use smaller bolts, but don't go any smaller than 1/2 inch. This will get you a little more adjustment. You might also have to grind a little off the steering knuckle to allow it to tilt more towards the strut. For more than about 7 degrees on the Mopars, you'll have to lengthen the lower control arm. This modification was OK'd a few years ago and hasn't been disallowed as of yet. It creates a few headaches though. The right axle is now a little short.

 

In the rear, the camber is adjusted with shims. There are four bolts that hold the spindle to the axle. Shims between the spindle and axle at any of the bolt locations will tilt or turn the spindle in relation to the axle. This is how you adjust the camber and toe in the rear on the Mopar cars. Some of the other cars are done similarly while others may have adjusting cam bolts.

 

> What are typical Toe setting settings for the front and rear?

 

This can vary due to car and driver preferences. But generally, I've found anywhere from 1/8 inch to 1/4 inch toe-out works on these cars.

 

> If the more toe out is added, is it done on the left or right side?

 

Start by centering the steering rack and then adjust the toe equally on both sides to get the toe-out you want. Then when you want to change it slightly, just adjust one side or the other a little. It doesn't make a great deal of difference which side you adjust as long as it's only a minor change.

 

> Should you have Rear Sway bars? if so should they be thick or thin?

 

The Neons and other cars with fully independant rear suspension might be slightly different in their handling setup. A top Neon team can help with their setup here.

 

I'll mention what can be done with the Shadow/Sundance/Daytona type cars. This also applies to other makes of cars with similar rear suspensions. You want to soften the roll in the front and stiffen the roll in the rear. What this means is you either want a softer swaybar or no swaybar at all in the front. In the back, you want a swaybar or a stiffer one than you already have. Most of these cars do not come with a rear swaybar. Ever since this class was started, many of the faster teams have been looking for ways to stiffen the axle itself. The axle in these cars acts like a swaybar. If it can be made to have more resistance to twisting, the car will handle better. This is what happens when you see the left rear tire coming off the ground in the corners.

 

> Front Sway bars, do you use them? thick or thin ones?

 

Answered above. I prefer not to use a front swaybar.

 

> How much faster did installing the right gear ratio make your car?

 

It depends on what ratio you are comparing to. In the case of the Mopar cars, there is really only one ratio to run at Spartan. Any other setup will put the engine over 6100 rpms and will cause the built-in rev limiter to kick in. The .91 ratio transfer gears are needed along with the 2.86 ring and pinion gears. The transmission is run in first gear.

 

For Springport, you can install the commonly available 1.06 transfer gears and run fast. With the rare 1.22 gears, you can run a little faster, but not much. The 1.06 gears are just about as quick if you're running by yourself, but if you get in traffic and have to lift off the throttle, it takes longer to get back up to speed. You have to keep your momentuum up and try to run in the outside groove to keep your speed up.

 

> When weighing the car where you can read the weight of each wheel,,,

> which wheel should weigh the most?

 

The left front should be the heaviest.

 

> which wheel should weigh the least?

 

The right rear should be the lightest.

 

> what is a typical crossweight % ?

 

Exactly opposite of what a rear wheel drive car should be. When the computerized scale is displaying cross weight, it should show something like 45-48 percent. This is actually 52-55 percent using the LF and RR wheels for the calculation.

 

> Do want more weight % on the front or the rear?

 

You want to shoot for about 2/3 of the car's total weight to be on the front axle. Make the rear of the car as light as you can.

 

> Waht is a typical front weight % ?

 

A good car will generally show 62-67 percent front weight.

 

> When adding lead to a FWD racer, where should the weight go?

 

Towards the left front but behind the LF wheel and down as low as possible. If you can't fit it in there, then it should still stay on the left side as much as possible. Don't put the weight in front of the front wheel and don't add any behind the rear wheels.

 

> The stiffest spring(s) should be where?

> The softest spring(s) should be Where?

 

The front springs will always be the stiffest. The rear springs don't need to be stiff at all since they are carrying very little weight.

 

> What should the HOT tire pressures be?

 

This can vary a little depending on the car and the tires being used, plus the driver preferences. But generally, I've found the following to work good when coming in after a hot practice session:

 

RF 50-54

LF 43-46

RR 42-45

LF 50+ (make it hard so it rolls easily)

these cars Are NOT allowed Locked or posi-traction final drives, Max tire size 195- 70 or 75 series, and must have Stock engines and suspensions.,,,tyhey run on 1/4 and 3/8 asphalt tracks...

 

 

Mr. Holt, what is your baseline setup with a FWD car?

are you allowed locked or positraction final drives?

what tire sizes do you run? street or racing tires?

Stagger?

dirt or asphalt?

 

Thanks, Your Info will help many new racers.

[tps48]

Most of us 4 cyl FWD cars run on asphalt. Most run a locked diff. (maybe not CC thunder)

We race on racing slicks w some stagger.

Mr Holt has been helping 4 cyl cars go faster since I first met him in the mid 70s

While I would be the first to say there is more than one way to skin a cat, I can attest

to the fact that my car gets around the track faster thanks to Nick Holt.

Mr. Arnold. It would not be fair to those teams I have worked with in the past to divulge specific set up information, so I will explain using generic concepts.

 

Frankly, the advice that was given regarding front-to-rear weight distribution and spring selection for a FWD car is questionable at best. While it is possible to balance just about any weight/spring combination, it is far better to set up around known physics principles.

 

A FWD oval track race car, like most other oval track or road racing cars, should be as near 50%-50% front-to-rear weight distribution as possible. While it is highly unlikely that any FWD teams would be able to obtain this ideal distribution (unless the rules required a very heavy minimum weight), that's the direction they should be headed. The closer one gets to a 50-50 setup, the fewer handling crutches are needed to balance the car.

 

And, contrary to what many would consider "common sense," the lighter the rear of the car is, the stiffer the rear springs need to be, especially the right rear spring. Or, the stiffer the rear sway bar needs to be.

 

Likewise, the heavier the front of the car is, the softer the front springs should be, especially the right front spring. Or, the softer the front sway bar needs to be. Obviously, there are limits as to how soft the front springs can be so you will often see front-running FWD cars with large rear sway bars and stiff right rear springs to compensate for the understeer that is generated by having so much weight at the front.

 

I do not have the space or time to fully explain roll couple distribution theory here, but I do explain it in detail in my suspension seminars, complete with class notes.

Mr. Knotts,

 

I just assumed you weren't listening while I was ranting and raving about suspension theory. I figured you were mentally planning your next cruise to the Bahamas, Europe, etc., instead.

 

Nick

[tricknology]

Dear Mr. Nick Holt,,

 

I am NO expert on FWD racing chassis setrups,,,,mainly just a messanger.

 

But Perhaps we are compairing apples to pears here, and that might explain the different chassis setups.

 

Most 4 cyl FWD classes;

 

do not allow locked final dirves ,,like your class does.

 

do not allow racing tires,,, like your class does.

 

do not allow excessive lightening of the chassis/body,,like your class does.

 

do not allow extensive engine mods ,,, like your class does.

 

I know that in RWD bomber classes that do not allow locked rear ends we wind up running a lot wedge and put a lot of weight on the LR to get it to hook up the rear wheels,,,when we switch to locked rear end we decrease the wedge and remove weight from the LR. Maybe the same thing is happening here with the FWD cars?

 

Also withthe min weights most classes have and not being allowed to gut the car to reduce wieght,, many cars are already over weight, and already have big front weight %,,,to get 50/50% weight ballance they would have to add 100's of pounds of lead the the rear and then be 100's of pounds too heavy.

[thumper]

Messed that up.On added weight,CC Speedway made me add 280#s to my Scirroco so I added it under the seat and on the left side .rear.To my surprise the car handeled better.Open diff and street tires on a 1/4 mile hi banked asphalt track.Push was reduced and not spinning the LF anymore.Downside is it takes longer to stop.Lap times are better.Trick guy the 4M website has gone through a total makeover,how did you find the old stuff.Wish you had all that info for VWs,Im not a big Neon fan.

[neon14]

thumper, how come you dont like neons?

[thumper]

YOU!!!!! Life was fun till you showed up.Cant intimidate you,cant trick you,cant outrun you,cant even make you nervious anymore.Glad your going Pro.I still see Neons rather than sheep jumping the fence when I cant sleep.

[tps48]

Well Mr. Holt, as a matter of fact I just returned from 2 weeks in Egypt. 1 week scuba diving the Red Sea.

1 week learning the secrets of camel racing (2WD & 4WD) Also, the cab drivers in Cairo would make great race car drivers. They are crazy!

Dear Honda Experts and including Mr. Holt,

 

Here in the Midwest many tracks and the IMCA have created Pure stock classes based on the 4 cyl FWD sedans that are plentiful and cheap. The HOt cars typically seem to be Honda civic, Mitsubisi Eclips, Hyudai Tiburon, Neon.

 

Typically these class rules are;

 

do not allow locked final dirves

 

do not allow racing tires

 

do not allow excessive lightening of the chassis/body

 

do not allow engine mods, only stock Fuel inj allowed, even the exhaust manifold must be stock

 

the car , suspension, and engine must ""LOOK STOCK TO THE EYE""

 

Given these constraints, and if you were asked to build the IDeal Honda,,,

 

Which Model, engine type, trans type and Year HONDA would you build and WHY?

 

Also please expand your choice to intalling a different model Honda engine into a Civic,,, such as installing a bigger engine from a Accord or Integra,,,

[tricknology]

Based on these 2007 IMCA rules, which HONDA car (model, Year, body style), Honda Engine and trans should a new racer pick to build and race??

 

Which tires would you suggest running ? ( TIRES AND WHEELS: OEM DOT 13, 14, 15 or 16-inch passenger tires only. No racing, mud or snow tires. No re-caps, softening, conditioning, siping or grooving allowed. ) ??
