Re: " Scattershield " Do you need one ? (vetterdstr)
Well you are all in luck Roger Vinci has had one for years and one is going on my stroker this week---call Roger or Joe Vinci at 407-292-4500----I will post this I thought everyone knew--
The one roger uses is a 1/4" of steel that will fit, it will deff stop a lot of the damage but mainly built it to protect the driver--they have seen a car with the dual disk setup send parts through the windshield, inspired them to build what they could--
Re: " Scattershield " Do you need one ? (z-u-later)
someone had a Cartek clutch expode on them, it was a downright scarey story. You can get killed by one :eek: no matter what brand it is. I also believe he had over 550 RWHP.
Re: " Scattershield " Do you need one ? (knewblewkorvette)
Yep, I've seen a number of clutch/wheel explosions over the years, and it is stunning the amount of damage that takes place.
Bill--is Roger's device a plate that he adds to the car, in addition to the bellhousing, or is it a total bellhousing, like a good, old-fashioned Lakewood blowshield? I'm thinking it's some sort plate he adds, right?
Another thing, guys. No blowshield in the world will contain a cast iron wheel or pressure plate, because they become chunks of shrapnel, going straight out from the crank centerline with mucho centrifugal force. I've seen Lakewood cans blow apart from failed cast iron wheels. The proper method is to go with steel wheel and p-plate. Should they come loose, they stay in one piece (most of the time) and simply tend to spin around in the can. Damage to you drivetrain is still massive, but it won't come through the floorboards!! Of course, if good aftermarket steel stuff is in a stock aluminum bellhousing, it will probably saw it's way out of there, but it won't be a violent hand grenade explosion!
If I remember the pics correctly Vinci's shield goes on top of the factory bellhousing. Not a true Lakewood scattershield but better than nothing. Are there any blankets out?
Some guys use a transmission blanket but there are clearance issues on the C5 between the headers and bell housing that make for a difficult install/fit.
Re: " Scattershield " Do you need one ? (AnteVenom)
Were the blankets covering torque converters? Blankets won't do much for a wayward flywheel/clutch/PP assembly. I wonder if the fast A4 guys are putting blankets on their trannies back there? TurboHydro-type trannies generally don't blow up like Torqueflights do. (no drum/band stuff, only clutch packs)
The blankets are on a MN6 and are wrapped around the bell housing.
You are correct that that will not prevent any damage from a wayward flywheel but it will contain the type of explosion that has happened when the bell housing explodes like a bomb to the point where it will minimize the damage to some extent.
Re: " Scattershield " Do you need one ? (AnteVenom)
Ante--Yeah, you're right. If just the clutch disk lets go or anything else short of the wheel disintegrating, the blanket could help slow things down. Better than nothing!
I recall that I put a full Lakewood shield and block plate in my 340 Dart that I shifted at 7200 (killer motor!) and I thought I was very cool having the foresight to spend bucks on something that didn't make the car go faster. That was, until I found out that the stock 50 lb CAST IRON flywheel wouldn't have even slowed down as it exited that blowshield in five 10 lb chunks! I saved a few more paychecks and bought a steel wheel and good clutch stuff!!
For a normal car, if you have all SEMA approved stuff, including a blowshield AND a block plate, AND high-strength bolts for flywheel, p-plate, blowwhield and blowshield-to-block bolts, you're pretty well protected these days. NHRA really frowns on chunks of flywheel heading for the grandstands at about 700 miles an hour.
Re: " Scattershield " Do you need one ? (knewblewkorvette)
"Do you need one?" That depends on what you mean. Do you need on for your person peace of mind...That’s up to you. Do you need one if you run 11.99 or faster at a track following the NHRA rule books.... Yes.
I am not quite sure if everyone is running them or if the tracks are actually checking but in the 2004 NHRA Rule Book Page 199, Section 16 General Regulations, sub-section 2:10....
"All other cars using a clutch and running 11.99 or quicker must be equipped with an SFI 6.1, 6.2, 6.3 or 9.1 flywheel shield. ........... There shall be a minimum of seven 3/8-inch diameter Grade 8 Bolts or higher strength steel studs in the top half of the bell housing. There shall be a minimum of seven 3/8-inch diameter Grade 8 Bolts or higher strength steel studs in the bottom half of the bell housing used to fasten the bell housing to the motor plate.....Exceptions to the rule: Volkswagen and Porsche...."
I found a Lakewood blow proof bell housing part number for the ls1 (part number 620-15005) but I donÂ’t know if it fits in a C5 ls1 to the torque tube. Maybe someone will chime in that has had to put one in because of tech inspections.
