new Guards LSD diff
Just got my car back from S-Car-Go with a new Guards diff and a new bearing.
The thing is a beast. I've not had a long drive in it yet, but on the way home it feels like I have much more of the power getting on to the road. I'm somewhere over 500 bhp with an Andial "style" 3.8 build and 98k miles on the car, so I was probably running on a worn out stock diff. It feels so nice.
Anyone else have a similar experience to a new diff?
Pricey but fun.

I LOVE my guard diff. Been in the car for several years of track duty running 335 rear slicks and when I sent it into guard this winter for a rebuild he said it was still perfect! You'll be enjoying your diff for years to come

Just had my clubsport guard LSD 40/60 installed with some other goodies this week, picked up the car on fri, will be at the track today and see if I can tell the difference...

Yes, GTgears, love it. Just had 2 days of driving at Thunderhill and loved the planted power. I also have gtgears for short 3,4 and 5. They do whine as Rob at S-Car-Go explained. This is normal as you say from an older design? What can you tell me about them?

ALL of our motorsports gears whine. It has to do with a variety of things. It has to do with toothcount for example. A 996 GT3 uses a 1.56 3rd gear. Toothcount 25:39. Instead we make a 1.55 3rd gear. 20:31 toothcount. Fewer teeth makes for a more coarse design, but it is stronger.
It also has to do with tooth profile and helix angle. We'd make nothing but straight cut gears if people would buy them. They are the strongest. The ONLY reason we make helical gears is because Porsche owners refuse to buy straightcut gears. What you have is a more relaxed helix. Call it a marketing bait and switch. We make our gears helical because the market demands it. But we make them more laid over than an OEM gear. A few years back we added a bit more lean to the helix because we were getting too many complaints about the gears being noisy. We've always maintained that a motorsports gear is going to be noisier than stock. But given the number of P-car owners who mod street cars or who want a dual purpose track and street rod, again, we had to adjust our design slightly.
Technically, the newest design helical gears are not quite as strong as the older ones in your gearbox. But for someone building a racecar or doing a crazy turbo build, we do offer straight toothed synchronized gears. Lots of shops are using them these days, especially 3rd and 4th gear. Ever since 2005 when the Cup Car sequential came out with straight cut gears Porsche owners have started to warm up to the idea of straight cut gears in their cars. Now we sell 1 or 2 sets a week whereas 3 years ago, nobody wanted them.

Thanks for that information. I personally REALLY like the whine and the volume. It's not real loud but sounds like your driving a real purpose built machine. My girlfriend loves when I get into it hard especially in your 5th gear. Sounds like we're taking off in a jet plane, feels like it too.
Thanks.
Thanks.
