Another hurry up and wait episode.

LOL, it was take it Saturday or wait for a month or so when I had time. It was me, just had to suck it up and get'er done. They wanted the car next week.

Really good aero video.

Another good video about dampers.

Another good video.

Well it ended up NOT being my clutch, the flipping LSD that I JUST installed failed. :( Really damn frustrating. OS Given Super Lock LSD Spec-S is supposed to be top notch. Here's my timeline:

We installed at our shop on 2/11. We put over 600 break in miles then had it on the dyno to have a fine tune in place (previously tuned but I wanted a specific tuner to look over the vehicle.

After the dyno, we drove another 300 miles just regular driving and the first time I went wide open throttle in second gear, we had no acceleration. This was on 2/20 so just 9 days later. I was thinking it was the clutch so we purchased a new ATS Carbon Clutch from Japan that took 3 months to arrive bc of the virus, went to have it installed and have discovered it was actually the differential. So that Diff lasted 9 days.

Has anybody seen this happen? Any recommendations or where to go from here? Reached out to who I bought the LSD from but who knows how that'll go or how long to correct.

Wowwwww!!! BTW Ryan I would've gotten Seb some log runs but it's been 100 degrees if it wasn't raining here so I'm looking for some lower temps. Other than that it's great. Only odd thing is that before the manifold it would peak 1-2psi above target boost. Now it consistently sticks a hair under target, i.e. 14psi reads 13.9, 16psi reads 15.9 , 18psi reads 17.9 and 21psi reads 20.9. (Wierd to me.)

I changed the lube in mine around a 1,000 miles. Use only the OS Giken gear lube. Have over 4,000 on it so far.

That’s awesome man!! Sounds like it’s holding the pressure better! Curious did y’all run the dyno on the current setup prior to the new manifold being installed? Curious how you’ll know if there’s a power gain

Yea that’s all we used. I was at right about that 1k Mark, even had the fluid in my garage to change it to :\ did you completely stay off boost in that first thousand? I mean that’s the only thing I can think of as to why it failed so quickly. Maybe I did the dyno pulls too soon and needed to break it in more? Seems like 600 miles would have been plenty. Unless OSG dif is literally that fragile

Guess you'll find out for sure when you drop the diff. Would love to see pictures.

My car went from OS Giken install to right on the dyno with zero miles on it. No issues at all. I've put around 500 (not break in miles) miles on it since. I'm getting ready to change the fluid and it's going back on the dyno.

Awesome! Thanks for the insight. i was really hoping some had experience with this and puts me at piece of mind that I didn't do anything wrong.

Exactly, that's the frustrating part of it, I don't think the shop opened it up to be sure. They replaced the clutch, found that the car was having the same issue. Drained the dif fluid and said it was "burnt black" like it toast and then claimed that was the issue. I feel like there should have investigating.

I'm bringing the OEM dif back to him tomorrow so hopefully I'll have more info then.

No issues with mine and I have over 30k on it. Only the last 7k with the built motor etc. I did install a diff cooler during the TT install.

Yea that sounds like a must! We never got on it enough for it to burn up this fast BUT before we go to the track, I’ll definitely want to add that!

I have a diff cooler too with gauge. When it's 90F, the diff temp will be around 250F after about 30 minutes of driving at 65+ mph. Turn the pump and fan on. The diff temp will drop to around 190F.
