Sprint Cars and Dirt Oval

lil_general_lee · #1 06-15-2005, 11:31 PM

I havn't seen a forum for sprint cars or dirt oval cars so I decided to post this thread. I've looked at a couple of cars by Custom Works, Bullet Racing, Kleins and others. If you have one please feel free to post pictures and talk about it, Nitro or Electric.

I recently picked up a Custom Works Enforcer GBX Sprinter.

Well, mine's raced on a paved oval, but with a couple very minor changes it'll be ready for dirt. I built this one from the ground up. It utilizes a old Traxxas Nitro Hawk tranny, and Nitro Rustler front bulkhead that has been modified a bit and mounted backwards. The chassis is made out of old street sign aluminum and reinforced with 1/4" aluminum square stock and the shock towers are made from 1/8" 6061 T-6 aluminum. The a-arms are HPI Super RS4, with RS4 front hubs and axles, and Traxxas Nitro 4-Tec rear hub carriers and axle, with modded Nitro Rustler slidders. Tires and wheels are HPI Super sized with 35R compound in the rear and 33R compound up front. The body is a IMCA style I got from McAllister Racing. http://www.mcallisterracing.com/racing/

Hey I remember you. You have had that car for a while. I posted wit you on Affordable Nitro Tech. Believe it or not, sprint car manufacturers post here too.

Our car just came out in RC Driver this month (Actually the November issue).. You can check us out on line at outfrontframes.com

DirtRacinFool · #6 09-20-2005, 01:38 PM

This one is a all new one, the one your thinking of is the old Kyosho Inferno 10 that I modified for oval. Congrats on making into a mag, and I do visit your site quite often.

My 2 Klein sprint cars

maxspeed_ozzy · #8 09-12-2006, 08:50 AM

HI guys,

I need some help I am planning on building some cars for myself (all quarter scale petrol cars) and I am considering building cars for sale (including tyres). It is some time off yet due to a shortfall in funds (low budget approach will be needed).

I need to acquire a lathe and a milling machine (CNC Mill)and I have decided that I will build the "CNC Mill" myself but I need to get some stuff together first. The "CNC Mill" will be used for production of most components for the car (mostly alloy & some steel), I hope to eventually fully manufacture the three types of car in-house (all my own design variations based on existing real life race cars).

I am very keen to get my hands on a Sprintcar and a Pancar to get a better idea of scaling of parts etc, What would help me enormously is if I could borrow or rent a car from somebody to assess the design and measure and draw up a set of plans for a "prototype" car that would then be heavily modified or redesigned to my specs.

I don't intend to race any cars at the present due to no tracks available here at the moment but hope to organize some guys into getting that changed.

I am also intending to setup a special low budget class car that will use "Ryobi or Talon" "whipper snipper" 25cc & 30cc motors in standard trim (no mods allowed). The idea is to supply a car that will use a $99.00 AU(25cc) and the other using a $169 AU (30cc) motor that can be purchased at any hardware store here and each of these motor's are very strong and reliable and easy to start.

I have so many design and production ideas running around in my head I am desperate to get it all started.

I would love some help in this direction from anybody and everybody I can get involved in this, can you help me ?

Some of the information I require for example:
• Chassis measurements
o chassis width - frame only - no suspension
o chassis height - frame only - no suspension
o chassis length - frame only - no nerf bars etc
o wheelbase - axle to axle
o Spring poundage - sprint rates - rough only - I don't all your secrets
• Wheels
o Size - 4" x what width
 LF - LR - RF - RR
o Tyre Sizes - in outer diameter & width (tread)
 LF - LR - RF - RR
o Stagger - rough only - I don't all your secrets
• Weight fully fuelled - - rough only - I don't all your secrets
• Radio control - what do you use or recommend
• Imperial or Metric parts for car and components, I'm still a little unsure of what to use for manufacture - the rest of the world (apart from USA) obviously uses metric for everything.
I just need some help with this project I not looking to steal anybody's Ideas or secrets ( I have plenty of my own).

HELP !~

Try my site www.quarterscalelegends.com , there is a forum there on 1/4 scale. To scale a car all you need is a model of a sprint car and scale it off of that.

yeeehaw · #10 10-08-2006, 10:55 PM

go see a sprint car race and get a pit pass. go to someone and tell them you are wanting to build a model and they may help you out. (by taking measurements etc...)

I would do that however there are no cars let alone races anywhere near me here in the North west of Tasmania.

That's why I want to build cars here and start a club in my city (Burnie).

I've been running a CustomWorks nitro sprinter for a couple of months now. Its awesome. I've been filming the races at the tracks I go to. Here are a couple of videos from Waco Tx R/C Speedway last Sat Nov 11th.

griz11 · #15 11-24-2006, 01:15 PM

Here is a pic of my customworks. It has a few hop ups from the stock kit. CW loose track kit with the .89 buggy shocks. CW offset kit. Klien transmission cases. Robinson tranny gears. Dynotech outdrives TC3 steering conversion wing sliders front and rear arms. Traxxas clutch and modified Ofna adjustable motormounts to line everything up. Spektrum radio and telemetry. Novarossi .12 power. Mc Allister Outlaw wing and Kipps front wing. Its a screamer with the Nova engine.

They have some pretty sick Sprint cars out, that Works Sprint is awesome. Anyone into Large Scale Sprint?
Anyone have any pictures with the body off any of these Sprint cars?

Thanks

griz11 · #17 11-29-2006, 03:52 AM

Here are some pics of the chassis only.

They are a blast to drive. I'm building an EDM now. I have the dirt oval bug real bad

Griz

Tig · #18 12-02-2006, 08:05 PM

Thanks Griz,
Nice cars, very sharp. Whats an EDM?
They have some pretty insane looking cars.
What are some of the companies that make these kits? Are there any really detailed ones out there? I went on DirtOval.com, they had some very detailed cars, that looked very realistic and it looked like they were made of metal to, some were large scale one as well. Wheres a good place to look for these bad boys

Thanks

griz11 · #19 12-05-2006, 02:01 AM

The links section at dirtoval.com is how I figured out what I know about oval so far. The cars with the metal cages and bottom plates are Klien sprinters. An EDM (East Coast Dirt Modified) is basically a RC10GT with some conversion parts. Funny you should ask I just finished building one tonight. This one has the OFF (Our Front Frames) conversion on it. They are wicked fast. The fastest EDM cars I've seen are all OFF cars. I'm thinking about going for one of their sprint cars also. I know the guy that makes them. He and I used to meet up on the dragstrip quite frequently.

This is an EDM (Butt ugly but fast)

And here is a peek under the hood of an OFF conversion EDM

And here are a couple of videos from last Sat's race.

sweet cars grizz. I really like the EDM!

I'm hoping to get a GSX from Santa

griz11 · #21 12-07-2006, 12:43 AM

I have mine all tricked out. Loose track kit offset kit dynotech wingsliders offsets for the rear wheels arms and tc3 steering rack conversion. Klien alloy tranny with RR gears inside. Its sweet and handles pretty good. Still have a ways to go to master setting one of these up. And the track changes so much between heats. I made up these videos today from some tape I shot on Sat.

how much stagger do you guys run?

griz11 · #23 12-11-2006, 11:50 PM

We run rubber tires at our track so there is no stagger in the tires. The foam guys run it but I haven't run foams yet. I'm going to Dallas next month to run on a couple of tracks there. One is a foam track and one a rubber tire track. Both are going to hold national races next year so I want to check them out. Trying to buy an OFF sprinter now. There is one at the hobby shop for sale. Those cars are unreal. If I get that one and win the GT2 for R/C of the Year on TRCZ I'll have 3 sprinters and an EDM

I want to convert the GT2 to an outlaw with an .18TZ in that puppy. The Pro Series is going to run .18's next year

The 27 car in this video is an OFF sprinter.

http://media.putfile.com/Nitro-Sprints-Q1-H2-Dec-2

A guy I know from drag racing makes them. They are based on a B4 instead of a RC10GT.

This is the new style OFF. Shorter wheelbase.

This is the old style long OFF Sprinter. Actually I like these better but they aren't making them now.

The brothers that drive those two cars are animals on the track. So smooth and fast. I'm grinding away trying to get my EDM ready for Saturday. The body is painted and drying and I have to rebuild the tranny and replace the rear bulkhead and it will be ready for a test run.

Lidz · #24 12-12-2006, 10:29 PM

Have you seen a 1:1 Sprint? They have such severe stagger they HAVE to turn right to control the car. Sometimes the car will corner without even turning the wheel left.

I'm thinking maybe you could run a truck tire RR and a buggy LR and get that thing to turn.

griz11 · #25 12-16-2006, 08:38 AM

I asked some of the faster drivers around here including one that drives for a factory. They told me that the little cars don't have to have such severe set-up as the big ones because of weight difference. For instance. Most 1:1 cars run positive camber on the inside wheel. As the 1:1 car goes into the turn and tries to slide to the outside it pulls that inner wheel more upright and give it the maximum contact patch while going through the turns. The 1:1 sprinters also have a solid rear axle which makes it harder to turn. I run offset on my CW. And mine turns on its own. You can also run different caster on either side of the front to get it to turn in also. You set these up to push going into the corner. As you go toward the corner you turn in and then let off the throttle slightly until the tire catches and turns the car. Getting them to turn in isn't as big of a problem as what they do when you mat the throttle coming out of the turn. Getting them to be stable coming out is harder to accomplish. Some things that help there are running less toe in on the inside rear wheel. A much harder spring/oil combination on the inside rear also. This throws all the weight on the outside front wheel when you let off going into the turn and 'sticks' that tire. Yea I used to go to Devil's bowl in Dallas a lot and watch the dirt oval cars. I love going to a WOO race. I'm just starting to learn all this stuff about the scale sprinters. Its very interesting and you have to throw out a lot of stuff you know works on other cars. The sprinters require quite a bit of finesse to run fast. The EDM's however are the 'mat and turn' class where you can really just hit the gas hard and not have to worry that much about it getting out of control. My EDM is almost finished. Still have to buy an engine and a steering servo. But the rest is pretty much complete.

Strange looking until you analyse why they look so weird. The whole body is a double decker wing. More for function than looks. I hated them when I first saw them run. But after driving one I bought one the next weekend.
