Sprint Car Bodies

[curtisp]

Maybe this has been asked and I just missed it. If it has, I apologize for asking it again. :D

I'm racing a JRC Lightning sprint. I was wondering if it is within the rules to use CDK part number CDKM023 (EDM Front Nose Piece)? By using a piece of kydex mounted to the front kick-up plate, the CDK nose would easily mount onto the car. I think that I would be able to bring the hood pretty close to the nose piece. Then it would just look like a two-piece hood. And, I do not plan on using that with a front wing too.

Thanks,
Curt

Good question Curt, it is not much different then using a Speedway Hood with the kick out and as long as it does not make the car longer then max length and the bumper still covers it/past it why would it not pass. Guess it comes down to the race directors call at each track and there opinion of the rules. Don't you just love that little bit usually put in at the end of rules.

Yeah...I love that part. :eek:

I checked the length, and it would be within the rules.

Mine is not a JRC sprint car, would love one of those, but I have been running one of those style fronts on my CW sprint. So far, know one has said anything, but then again, I have not won a race with it either....

Looks good! So, have you been racing where the DODC rules are being used?

Maybe I should check with Chris at Bumps & Jumps. I don't see it being an issue at my local tracks, but I want to make sure that it will pass at the Freeze.

HELLO?!?!?

Bueller???


Bueller???


Bueller???


:D


Rob...Todd...Chris...anyone have an answer to my question?

Thanks,

[bumps and jumps rc]

Looks fine to me, so yes. It must be within the rules though - I think Charlie makes a wide one that would be to wide and outside the dimensions. So as long as it meets the 3.6" or whatever it is supposed to be I am all good with it. Actually looks better than some of the other things I have seen on the front end.

[curtisp]

Thank you VERY much Chris!

[Rob Cutman]

The way we were addressing that at the Open Wheel Race was as long as it is less than 3.6 wide and did not overlap any portion of the hood behind it it was ok. Sorry for the delay in getting to your question. Hope this helps.

Thanks Rob.

OK...sorry to keep asking questions...but about the 3.6 wide. I'll have to check that part again, but if I remember correctly, it is 3.6 at the top, but at the bottom I think it is wider. If you look at the pic, I think that where it widens out next to the mounting bolts, it is wider than 3.6 So, will that make it illegal?

thanks Chris & Rob for your input.

[Dragula]

Just measured mine. It measures 3.10" at the top, and 3.61" at the bottom. Me, I would call it legal, but, I guess it would depend on the tech guy.

[Dan D]

looks like a front wing to me. its an edm nose leave it on an edm. isnt there a rule on bodies already? is this a grey area?

[signman501]

Yes it is Dan. But they are legal. It's like using a Speedway hood and just laying the front of the nose out some. Oop's, I shouldn't say anything about doing that.

[mikejhs82]

I second that Dan. It is an EDM wing.Use the front bumper and stock hoods like a real sprint car. It says no additional pieces of lexan which can act as a wing or that enhances aerodynamics. If you need more traction on the front, move the wing forward..


My $.02:)

No gray area..pretty specific..

from the rules cut and paste..

"No lexan or any other material may be mounted to nerf bars, bumpers, cage, wing or any other part of the car that will trap, alter, or direct air flow for the purpose of gaining an aerodynamic advantage."

[signman501]

Can't use CW type stock sprint hood on terminator style cars. But should fabricate a front bumper. I've seen several cars that are well done and some that are really shakey. It's up to the tech man to decide how they want to see it. That nose works well as long as it has a bumper mounted out front.

[Doug D]

It's up to the tech man to decide how they want to see it.

I totally disagree, its up to tech to enforce the rules as they are written, not "how they want to see it".

I have to agree with Dan on this one, it looks like a butchered sprint car to me, the down tubes / frame rails are cut at the front towers w/ no bumper????? I'm a big advocate of trying to have the cars stay within scale and look real, and totally support the DODC Rules Package.

Ahh, but there are those already who feel that is ok. The only way around this whole debate is to take all of the member tracks who will be taking on the DODC rules package and hold a "Tech Seminar". This will quash any debates and eliminate any percieved gray areas. This may sound extreme and not realistic, but it is a way to end all debates over the rules, percieved or otherwise.

But the reality is these are toy cars, you or I don't make a living from the prize money and trophies we win. So again, is it really worth splitting hairs over.......

I totally agree...it is up to tech to enforce the rules as they are written. My post was just asking if that style of front nose would be allowed. And, although some people might think that it clearly states in the rules that it is not allowed...I think that depends on how you interpret what is written.

Here is what the rule states:

Sprint Cars
Must have scale appearing cage, hood, side panels, nerf bars and bumpers. Minimum of a 4 post cage required that resembles a drivers cockpit. A driver arm guard area is permitted on right side panel bust must be of reasonable size. All electronics, radio gear, fuel tanks must be positioned inside the cage side frames. Three dimensional scale appearing exhaust headers must appear on both sides of car in “engine area” and be made of round stock or molded polycarbonate (left side of nitro sprint is optional). Rear cage side panels may be used but may not extend beyond rear cage frame. No lexan or any other material may be mounted to nerf bars, bumpers, cage, wing or any other part of the car that will trap, alter, or direct air flow for the purpose of gaining an aerodynamic advantage. Must have appropriate openings on both sides of cage in driver compartment, forward portion of side panels can be no taller than highest point of hood, no solid side panels.

OK...a scale appearing cage, hood, side panels, nerf bars and bumpers. There are two piece hoods available for sprint cars. Here is a place that offers sprint car hoods (http://www.tqfiberglass.com/sprint-car-products/sprintcar-hoods.html) and sprint car noses (http://www.tqfiberglass.com/sprint-car-products/sprintcar-noses.html), which is pretty much what I was thinking of doing. Here's a close-up (http://www.tqfiberglass.com/sprint-car-products/tqh007-lside-front.JPG) that shows where the hood fits under the nose on a sprint car, also note that the downtubes are not on the outside of the hood. Here is another link (http://mysite.verizon.net/vze70w1t/id9.html) that shows sprint car hoods & noses. Oops...and one more link (http://www.sprintcarexchange.com/hoods_panels.htm) showing sprint car hoods and noses. Now...I do NOT race full size sprints and know very little about them...so...maybe those are not used and I am completely wrong in looking at those as examples.

As for the part about No lexan or any other material may be mounted to nerf bars, bumpers, cage, wing or any other part of the car that will trap, alter, or direct air flow for the purpose of gaining an aerodynamic advantage., which I am guessing is what some might say clearly makes that nose illegal. That is the part that I think depends on how you read it. I'm not saying that there is any grey area...and I am not trying to create one...it's just that written words can easily be read with more than one meaning. I completely understand the no lexan mounted to the bumper...but...what I also read as I continue to read that sentance is that will trap, alter, or direct air flow for the purpose of gaining an aerodynamic advantage. To me...when I read that...I can't possibly see how using a nose like the one in the picture that I posted would be an aerodynamic advantage. Here (http://www.customworksrc.com/product_images/9022hr.jpg) is the Custom Works Speedway hood. I don't think that the nose that I was asking about would be an aerodynamic advantage over that.

So...that's why I posted this in the first place. I was just asking for clarification, which I got from Chris & Rob. :thumbsup:

I did not mean to stir things up, I just want to make sure that my car passes tech. I want my cars to be legal when I get to the track, I don't want to wonder if it will pass or not.

I love the educated,disussion as gentleman. I mean this sincerely.

I agree the plastic nose piece as installed in the pic is not that far off a "real looking" sprint car referring to Curts links. I would be happy if it had a roll cage extending beyond the front shock tower,and the part ahead of the front shock tower was not wider than the cage. A front bumper beyond the chassis plate, made of nylon or some other material that gives or flexes, would make it compatible with PA nitro tour rules as well.The bumper you guys suggested should not be wider than the rollcage width as stated in the DODC rules.

Mount the piece you cutoff the cage, on the existing front mount that has the 8-32 screws through it, utilizing the front bumper originally molded as part of the cage.

I might be a bit biased,But I like to make it look like the pictures Custom Works shows on the boxes. Although they are a little dated..lol Hint ,Hint Rob..CW has had the same design for a LONG time.. I love creativity..and seeing how fast you can make your car within the rules. Sorry to be so blunt at first..But I think that your nose piece just pushes the limits a bit to far and falls outside the "spirit" of the rules..

Just my $.02

Curt

so if you read the above statement and understand the meaning. why would you ask or attempt to push the limits. it is an air foil and everyone knows it. it DOES NOT in any way shape or form look realistic or like a 2 piece hood

[Dan D]

yes RJ they (some) feel it is ok. and they are WRONG they make the rules then they dont enforce them. i agree with everyone getting together and working things out but.......in reality this will never happen. and yes they are only toys but when you add racing and rules and money together...... yes it is worth splitting hairs over. all my cars are legal by the rules published and it should be an even playing field for my toy.

[curtisp]

Looks fine to me, so yes. It must be within the rules though - I think Charlie makes a wide one that would be to wide and outside the dimensions. So as long as it meets the 3.6" or whatever it is supposed to be I am all good with it. Actually looks better than some of the other things I have seen on the front end.

Thanks guys! I just measured it, and it is 3.6" wide at the widest point.

[Dan D]

yup guys. THANKS for opening up the GRAY areas.
