Hey does anybody know where I can buy a scatter sheild for my car? NHRA legal.

Also what about NHRA legal studs for the rear wheels?

Thanks alot guys,
Phil

 

This is the only SFI bell housing that i know of. I think they only make them for a push type clutch though. There are several companys that make scatter shields that meet the NHRA requirements except they are not SFI.

Your choice either one will work. I personally have the steel one from theracingstore.com fits very tight to the bellhousing I really like it. My buddy has the blanket on his works fine also. On the studs I believe Moroso makes some.

 

Thanks you so much bro.

Are these the right size 3" axle studs for the stock hubs and wheels?

#7713 are the correct ARP studs,
Tony @ the racing store needs someone with a FD bell housing to send him one b/c he only makes about 1 FD scatter shield a year and the bell housing he had broke. This was as of last Tuesday.

260$ plus I have to send you my bell housing for 5 bends on a press break and 4 tabs welded on. I’m having the guy who built my cage make me one for a lot cheaper….

 

Make sure you've got that SFI Legal Sticker on there or Gateway tech will throw you out. Anyone can build you a scatter shield but it's got to be legal. Gateway tech won't let you slide no matter who you are.

Blankets aren't legal for your 5 speed.

 

Does anybody else make a FD3S NHRA legal scatter shield?

 

Nobody makes a Legal SFI Certified Scatter shield. They do however make a SFI Legal Bellhousing for $1,400

I called them about this and the guy they had make them has disappeared and can't be reached.
If you guys find one that'll work, lemmie know! Are we allowed to use that blanket thing? If so, it looks alot easier.

 

You could always go this route. http://tricktitanium.infosaic70.com/Bell%20Housing.htm

 

How did Ari, peeter, and Adam S do it then? my local trac just wants to see it. i dont think they can spell SFI lol

I talked with SFI, becoming a vendor is gonna be about as costly as buying 1 bellhousing.......wonder if the new label printer at work can......

 

From the NHRA rule book.

Exceptions to this rule: Certain engines are not required to have a shield when they are normally aspirated and gasoline burning, and certain engines must use a steel billet flywheel in lieu of a flywheel shield. Some engines for which an SFI 6.1 or 6.2 Spec adapter shield is not commercially available, must be equipped with a flywheel shield made of 1/4-inch (6.35 mm) minimum thickness steel plate, securely mounted to the frame or frame structure and completely surrounding the bellhousing 360 degrees. The flywheel shield shall not be bolted to either the bellhousing or engine. The flywheel shield must extend forward to a point at least 1-inch (2.5 cm) ahead of the flywheel and 1-inch (2.5 cm) to the rear of the rotating components of the clutch and pressure plate. Other engines, where an SFI 6.1 or 6.2 flywheel shield is not available, may use an SFI 6.1 or 6.2 flywheel shield from another application and mount it to a motor plate which is mounted to the engine block at all available bolt holes. The FIA Drag Racing Commission will establish a list of such exceptions, to be published annually in the FIA Bulletin.


Maybe you should contact the NHRA for clarification.

 

Well since I don’t see any thing on the mkt that is actually SFI certified in the way of scatter shield, from what I’m reading on here and in the NHRA rule book it will have to mount to the car not the engine, and since I don’t think any of us are running motor plates…

All of the scatter shields you see out there are mounted using the factory bell housing bolts.

When I spoke with SFI the only MFG’s who even started the process for 13b’s were JW transmission (Tracy winners 321-632-6205) and bob Stroud of Stroud safety (405-632-2022)
To become and authorized SFI producer of a scatter shield you have to send them 3 production copies and the fee for their testing (1,000$) I had them send me out the info to see what their requirements are for design. I know my fabricator can build it but if its going to mount to the body my time table is going to get all screwed up. Im sure an hr or 2 with photo shop we could come up with a design for a label printer. What I really want to know is what people like Dan, and Ari are running. b/c if we can get away with having one that mounts to the bell housing that would be great.

 

Ok I stand corrected, for all the hassle of this I may just buy one from Campbell and just peel off the sticker and put it on mine, for 68$ s going to be the easiest since its off a flex plate shield, SFI 30.1

http://www.campbellenterprises.com/flexplateshields.htm

I feel like a ricer even having to think about stealing a certification label, but 3/16 heat treated will hold up even better than most of what’s commercially out there. Ernie, the blankets are or auto’s but with the power your making it might be a good idea, the tranny tunnel isn’t that thick and walking/living will be worth the price of the blanket.

 

Meant 5 not 3, waiting to get data on tensile strengths vs. weight properties on 5/16 vs Ľ.

 

Some engines for which an SFI 6.1 or 6.2 Spec adapter shield is not commercially available, must be equipped with a flywheel shield made of 1/4-inch (6.35 mm) minimum thickness steel plate, securely mounted to the frame or frame structure and completely surrounding the bellhousing 360 degrees. The flywheel shield shall not be bolted to either the bellhousing or engine. The flywheel shield must extend forward to a point at least 1-inch (2.5 cm) ahead of the flywheel and 1-inch (2.5 cm) to the rear of the rotating components of the clutch and pressure plate.

This is the key statement for our vehicles; the only place in the NHRA rule book that this loophole is not available is in the Modified, and Pro RWD class. In both of these classes you HAVE to have a 6.1 or 6.2 certified unit. The Rule book specifically singles out the rotary motor. In the ET brackets and general rules this “loophole” holds true until the vehicle runs 9.99 or over 135MPH, then you must also have a SFI rated piece.

Bad news is All 6.1-.2 units are containment bell housings, not “scatter shields” as we are all accustom to seeing” And there's NO WAY a rx7 bell housing will ever pass. This is due to the design of the Mazda bell housing. There are not enough bolt holes to even get into the SFI testing. (Ive spoken with SFI Tec dept 4 times this week, they even have a bellhousing that a company produced, but couldnt take it to testing b/c it didnt pass prelim requirements)
SFI will not have a rating for our bell housings until someone like the NHRA or IHRA contact them and have them create the Spec.

SO from my research of your going to run Modified, or Pro RWD your screwed. Or if you car has 9.9 or 135 in her (Ernie) you need a SFI rated piece. But since there’s none out there it will be left to the decision of the sanctioning body running the event. In this situation youll end up running a motorplate and SFI bellhousing.



Basically the ones out there that bolt to the bellhousing are not legal in any sense of the manner for our vehicles. The shield has to mount to the frame/body (tranny tunnel in our case)
For the rest of us there’s hope, I should be getting my FD back from paint in a week or so. From there fabing this shield will be a breeze. After we have the final mockup’s done final mounting points will be decided. For cost sake it will be out of the required Ľ in Steel. Future models will also have the choice of 4130. The Shield will exceed the NHRA rules and regulations. So Tec inspection shouldn’t be a problem. It will mount to the tranny tunnel/framework; will cover 360 Deg, with removable bottom. All hardware will be Grade 8.

Additionally the flex plate shield's on the MKT will do you no good as their SFI level isn’t correct. since their built for autos

 

Bacon, I still want one!!! Let me know when you start on it.

 

Well were roughly 2 weeks away, no ones fault aside from the painter. Spoke to him yesterday,, and they were finishing the last of the bodywork, there’s a little sanding left then the painting begins later in next week, so if things go well I should have something by Sunday afternoon. If it goes on schedule the 21st will be production date. From there ill get yours on the road. I’m going to send mine and an extra one off to powder coat to make them all pretty.

IF the painters not moving fast early this week ill just pull the Trans out of my silver one and use that for the mock up. But I’m not really in the mood to have to do that.

 

Hey Len,
Sorry for the late reply.
You guys are making this WAY to complicated.... Ari and I found no one at the time that made scattershields for our cars, and I'm not sure if there is anyone now. Blankets are not allowed for compensation, otherwise I would have used one of those at the beginning. The purpose of the scattersield is to deflect the flywheel from sawing off your feet (or more) in case the flywheel "scatters" or shreds into multiple pieces of an 7000+rpm saw.

In the rulebook it states that if running a manual stock transmission, you have to have an SFI spec shield, OR "Applications for which an SFI Spec 6.1 or 9.1 flywheel shield is not available may use an SFI Spec 6.1 or 9.1 flywheel shield from another application, attached to a motor plate that is attached to the engine block at all available bolt holes, or a fabricated shield made of 1/4-inch-thick steel, surrounding the bellhousing 360 degrees, extending 1 inch forward and 1 inch rearward of the rotating clutch assembly. Shield must be securely attached to frame or frame structure; may be multi-piece."

All I did (Ari did similar), which is perfectly legal, is take a 1/4" piece of steel from Home Depot 2.5"-3" wide, and bend it in a vise to fit around the bell housing, then welded on steel tabs to mount to the bell housing bolts. No SFI sticker needed. It's as easy as that. Hope this helps .

 

I love to overcomplicate things. Looks like the ball will begin rolling a lot faster now

Thanks Dan

 

I wish our local track was that lenient but they aren't. Our track is well known for their **** Like Tech Antics.

No legal SFI Sticker, No Care. No NHRA, No Care.

 

Anytime .

 

Have you tried passing without a sticker?

 

Yep and was shot down.......... so I took it off. Buddy tried the same thing with a home made scatter shield and slapped a SFI sticker on it.

I've learned one thing, when you try and pull one over on the NHRA Tech guys, they'll make your life a living a hell from then on.

I eventually bribed one of the new tech guys but that only lasted two races before the big wigs found out. They love to chase me down on their scooters.

 

If it meets the NHRA rules, how can they still not let you? I mean there’s no way to have a SFI bell housing due to the lack of bolts, unless you’re running a motor plate. I have the paperwork from SFI on my kitchen table, it’s like 8 bolts on top, 7 on the bottom...

Someone would have to make new rear housing, with many more bolt holes, then make a bell housing to match it…. Talk about cornering the market, wish I had the resources….
