Heed this warning

I was 14 at drag strip when a car coasted to side of track , a 4 speed car . Same thing , cut both man's legs off and he dies before they got him out . Never forgot it neither . I never run a 4 speed without a blowproof bellhousing . If you ever see a tranny spatter you would run a scattershield . When it blows that will allow all metal bounce around without coming into the car . Bless him and his family .

Another overlooked area is the flywheel bolts themselves.

I have seen lots of times where guys just re-use old bolts thinking they are fine... they are not. If you pull your old bolts and examine them closely... more than likely you'll find that they have stretched.

When ever doing a clutch or taking off your flywheel... always get new bolts.

Does anyone know of a situation where someone was seriously injured and they DID have a scattershield?

thats it for me,ive been spinning my 82 up to 6500 with stock everything[gearbox and bell wise],no more though=ill be investing in a scattershield asap,im attached to my legs and would like to keep it that way

Ya, same here. When I get around to yanking the engine out of the 75 gonna get a new flywheel and a scatter shield to put in there.

That's the whole reason why Don Garlits pioneered rear engined dragsters.
Because he lost parts of his legs in a front engined dragster explosion.

I know big cats are governed at 2100 rpm, and cummins are at 2000rpm. Light duty diesels like Powerstrokes go to 3,500 rpm.

The force on the flywheel must have been mind boggling. I can't nor want to imagine the explosion. Hopefully the guy is doing alright. At least prosthetic legs are good enough where he can live a pretty normal life again.

You know... The more I think about these damn car's and their exploding flywheels and the Mopars with their exploding flexplate styled convertors I am betting that these big dragster and funny car drivers DO and HAVE had scatter shields... If you're running a 10 second 1/4 or a 10 second 1/8, it would make sence to have one!

So to reiterate Jon's post, HAS ANYONE SEEN or known of a blow up WITH a scatter shield?

Man, sign me up. My dad has made commits for years about exploding flywheels that I kinda shrugged off. Now w/ kids in the car and all, I'm for sure going to a scatter unit in as soon as funds and time allow. I don't drive it much but lately have been taking my 3 year old on cruises around town. I strap him in his carseat in the front w/ me, I just don't want to think about something happening to him...

You guys are right, usually big trucks don't spin up that high. We don't really know what happened, but he had just finished changing the turbo out and was taking for a test drive. It's a cat 3406 engine. I'm not sure if the engine electronics just let it run away or what. All I know is i've seen gunshot wounds bad cuts and alot of gore in the military, but i've never seen anything else like this. Give yourself some sort of a saftey cushion though, that's all i'm saying.
