LS Bellhousing Question Hey Guys. I am planning my LS build and I have a LGT-700 transmission. I am on the fence between a cast aluminum bellhousing and a Quicktime unit. Trying to spend money wisely and knowing that this car spends most of it's life on the street, I am trying to decide if it makes sense to spend the money on a Quicktime housing. Thoughts?
Thanks.
Thanks.

The two guys that responded with Quicktime have cars with slicks on them. I can understand the need for a scattershield with these cars. My car is a street car so I am looking at if from a necessity stand point.

Launches and extreme rpm's would be the most damaging things to clutches.
Drag use certainly experiences the hardest launches, although some of the drag rules are also based around ancient junk and more shoddy DIY modifications, so are probably less valid today when buying proper product is very cheap, and even OEM parts are a very high standard.
But steel would give you peace of mind if nothing else. Ive heard of clutch/flywheel explosions, but never seen it happen myself. There's usually more to the story than simple product failure.

QT has been fine on mine.
That said, it needed clearanced for the slave cylinder pipework, and they had tapped the holes imperial instead of metric.
Allegedly this was an early mistake, it was some time ago.

Same here. I had only 6 launches on mine just on motor (512na) and I broke the bell by drivers side dowl. A stock bell was gonna run 450ish so I went ahead and spent alil bit more for the peace of mind.

Since then, I have used scattershields (steel) on anything over 300hp.
Same goes for using u-joints without zerk fittings. The fittings weaken the case. Use 1350's.
Saw a gasser blow up the front u-joint and the drive shaft came up through the floor and open the guys leg up to the bone from his hip to his knee.
But it is your money.

40 yrs ago at Englishtown Speedway (NJ) I saw a flywheel separate off the back of an engine and come through the dash like a buzz saw.

Again, can you show me an example of that sort of thing happening in a LS powered car using OEM parts? A LS7 Z06 has a factory redline of 7200RPM. Do you think that GM would risk that sort of liability?

As to GM liability.........how is that ignition switch from China case working out for them? Class action multi-million dollar lawsuit.

We put a steel one on anything over 400 hp. Why? Because you never know. We prefer the Quicktime piece.

That aluminum bellhousing did not contain that clutch.
Imagine if it was the flywheel?
Luckily it went downward and not upward.
