Scatter shields

[Pat]

When the trans comes out to replace the clutch in the Shadow, I want to fab up a scatter shield on the off chance that the clutch/flywheel come apart (I like my feet the way they are!). Anyone have a pics of one they've done?

[BadAssPerformance]

Working on a design right now.... Group buy?

[Pat]

I'd be interested.

Will it fit autos, too? If so, I might be interested (depending on price and timing). I'll need one if I ever get to work on my super stock engine/trans combo.

I'll see if I can get a few pics of mine and the one I did for Dan.

[mcsvt]

I'm on the interested list.

[Turbo3Iroc]

Add me.

It's a little known NHRA rule that our cars are supposed to have them if you run a bigger turbo. Most tracks let it slide but I have been asked about it a couple times.

[t3rse]

I'm interested pending price.

I think that rule is up for interpretation, Kelly. Some beleive it only refers to cars that were not originally equipped with turbochargers.

It very well could be but there is also a rule that requires us to wear a SFI jacket if you are running a non stock turbo. Doesn't matter if it originally had a turbo or not. I think the scatter shield is part of that. I haven't looked at the rule book so don't hold me to it. It was at Englishtown and LVD.

Either way, I think they are required at 11.49

[t3rse]

I also remember reading that a scatter shield had to be SFI approved meaning there was no way to get one for our cars...

True, there is not one SFI approved that I know of, but the rule states that if there is not an approved one available, that a sheild can be made from 1/4 steel. There are a few more specifics to it (which I don't remember off the top of my head), but there is reference our situation in the rule book.

Here is an article from the Feb '09 issue of Hot Rod.

Doesn't it have to be SFI approved for SS?

Art uses an SFI approved blanket on his auto SS Neon.

Must not be - Kish made his own, so did Artie as far as I know.

[22shelby]

i was thinking something along the lines of a blanket from like RCI...

http://www.jegs.com/i/RCI/821/7808A/10002/-1?parentProductId=753473

SFI 4.1 ?.?.?

but if BAP is working on one he want a test dummy to se if it will fit auto ill be a test monkey...

I can't speak for Tim, but I have seen Arties. I'll have to go through my S S/S association pics to see if I have any of Arts engine.

I'll quote the NHRA rule book tonight, but it can be fabricated if an SFI one is not commercially available :thumb:

For our cars, atleast the 5 speed cars I would be concerned with the blanket causing interference with the shifter linkage.

[cordes]

This is a great thread to see guys. I have always wondered why none of us run them (other than the obvious fact that they aren't made for our cars). When I think a safety item is a good idea most folks would have thought it mandatory long before.

At what point would this be a benefit other than just rules? I see most stuff holding together well, but there are more and more of us turning higher and higher RPMs too.

[t3rse]

All front-wheel-drive or transverse-mounted applications using a clutch and running 11.99 or quicker, for which an SFI Spec 6.1, 6.2, 6.3, or 9.1 flywheel shield is not commercially available, must be equipped with a flywheel shield made of 1/4-inch-minimum thickness steel plate. Shield must surround the bellhousing completely except for area of bellhousing adjacent to differential and axle shaft. Shield may be multi-piece, with pieces bolted together using minimum 3/8-inch-diameter Grade 5 or M10 class 8.8 bolts; may be attached to engine and/or bellhousing.

per NHRA rule book

[BadAssPerformance]

Thanks for posting that t3rse :thumb: forgot to last night after shoveling snow, LOL :o

[contraption22]

I cant seem to find anything for cars FWD cars faster than 10.99 but using an auto trans. Do we only need an SFI flexplate, or do we need a sheild too? Obviously the sheild would be a good idea either way.

[BadAssPerformance]

Probably a sheild if the flex plate is not SFI

[22shelby]

ahh didnt not event thinl about the 2 linkages... good call...

[contraption22]

Why you should have a sheild....

[BadAssPerformance]

It just got above 30°F this week, but probably a week or two off from looking at it.

Hope it helps!

[BadAssPerformance]

Thanks Brian, thats pretty much what I was going to do.

I was going to bend the tabs from the same metal as the sheild, but if welding is acceptable thats easier. I also thought it had to go completely around, so like underneath the trans too?

Welding the tabs did make for an easier build. As far as I know, it does not need to go completely around. If it comes apart, let it go out the bottom!

[Turbo3Iroc]

That is a lot simpler than I was picturing. Just enough to get the job done though. You're right, who cares about the bottom.

[Pat]

Going around the bottom wouldn't be a bad idea though...not only to keep anything from bouncing up and coming through the floor, but to keep it from bouncing out where others may be standing.

per NHRA rule book

Just checked the '09 book and it says the same, but 11.49

This is the part that made me think it had to go under as well:

"Shield must surround the bellhousing completely except for area of bellhousing adjacent to differential and axle shaft"

[t3rse]

I think it is pretty clear the way it is stated that it has to go under it too...though every scatter shield I've seen only goes over the top and around the back (Neons, Hondas...etc)

[Ondonti]

Betting most NHRA techs don't care too much as long as the Spirt of the Law is kept. Nobody is going to get hit by clutch parts unless they are standing in front of the car which means they were planning on committing suicide anyways.

Neon guy posted pictures awhile back of the destruction from his flywheel coming apart. Yes, dude is lucky to have his nuts intact.

BTW, what is an SFI spec 6.1 or 6.2 or 6.3 or 9.1 shield?
because the one described in that passage is not one of those. Maybe "real" commercial type ones don't have to follow the same rules.....Some of the safety rules really piss me off.

I'm a fan of all safety rules. The aftermarket OEMs have different rules because that can prove with test results the strength of welds, hardess of metal etc. vs. the shade tree mechanic who it is easier to tell him to make it 1/4" thick and heavy as hell.

[ShelGame]

What's the cost JT?

[rbryant]

JT,

I assume that this has been considered but... I would need it to not interfere with the 2.4l block when connected to a 568.

I have extra 2.4l to 568 dust shields that have the bolt patterns for both engines on them that I could send if that would help in your development.

Need to work on the design first... group buy, I'm not out to get rich so hopefully not too bad

The plan is to fit it on my 2.4L/A568 G-body and Tommys' 2.5L/A568 L-body so it should be able to fit anything else?

It bolts to the trans mounts, so the trans bolts runs through the guard to the block, so fitment shouldn't be an issue....

If the price is right I'll take one: it really comes down for me, whether or not it is worth the time (and me feeling motivated enough) to bust out the welder and torch.

The bottom front connection is the only concern I have. I guess that area would be avoided so that it isn't in the way of the front engine mount anyway though...

[turboshad]

Good thread which makes me realize that I should probably be adding a shield to my list of things to do this spring. Is there anything in the rules that would keep me from making it out of stainless?

Apparently they should be regulating them by the strength of your brakes and not how fast you should go.

WTF? Were the rims hitting the calipers or something? Even with the e-brake on I'd expect it to drag the back end around...

I think that person has never done a FWD burn out before and was on the brakes..

'durrrrr, it works great in my truck..' :(

i can't believe i missed this thread. you can add me to the list. i'm definately in need of one of these.

[Reeves]

Update?
Are these or the headers coming first?

[Tim Kish]

Mine is NOT SFI approved, I made it myself and worked with both NHRA and SFI on the design/approval. It was built to the requirements of SFI 4.1 without being submitted to certification. Per both NHRA and SFI if I were to commercially offer this unit it would require certification, otherwise they accept it as meeting the intent of the specification. For an ATX the requirements are different than MTX - ATX needs to cover the trans from the front pump to the transfer gear end with the exception of the differential area. MTX needs to cover the clutch portion of the trans (again excluding the Diff). For any classes we run an SFI 29.1 flywheel sheild is not required on the ATX.

At the end of the day NHRA tech even realizes that if an FWD trans explosion were to occur its not going to blow your feet off like a RWD car which is what the rules are written for. Now of course that said my 12.80 car still has to have a roll-bar, trans shield and I have to wear a full single layer suit (jacket & pants) becuase my class is lumped in with faster RWD cars. Which is fine as the highest risk is someone in an 8.50 car losing it in the lights and collecting me so I accept the safety equipment requirements on that basis.

[ShelGame]

Tim - can you post a pic of your shield? I don't remember what it looks like. I didn't realize it was supposed to go all the way out to the transfer gears. I have a pic of a SSGS Aires that was on eBay a while back. It didn't look like his shield when that far - but it may have been MTX...

[BadAssPerformance]

Sorry, nothing is happening to either right now, I dont have a big heated garage and my basement is full of crap I'm waiting to get moved out.

MTX needs to be 4" wide

+1 for pics

Material for prototype ordered

[onerippinturbo2]

any kind of idea on pricing as of yet? i am interested,just trying to plan as to when i gotta get one of these sooner or later in the build process.

[BadAssPerformance]

Not sure yet, got over $50 in materials ordered... fab time still TBD... I'm planning to use a spare trans case as a fixture, so whatever fixture costs will get divided by how many are in the group buy.

[shackwrrr]

I am interested pending price.

i am interested as well, mark me down for 1.
