First Track day with OS Giken LSD and extreme noise

Is the diff noise gone after it cooled down?

Yes, but the fluid is cooked. It will be noisier than normal until it is changed.

Getting the diff inspected and fluid changed.

I have reached my limit with this car. Just put KWV3 suspension on it and didn't notice anything major at the track and now I put a high end diff that cooks fluid in 8-6 laps on a humid day that just requires me to buy another aftermarket part.

Anyone want to buy a 370Z for 25000 with over 25000 in after market parts for cheap! lol

You will see it posted on the for sale soon!

I see you have ported intakes. Did you do them yourself? Thoughts on HP improvement please. Considering doing a port match job on mine.

BTW, it's my opinion that if you run a clutch style LSD you need to cut the yaw sensor power wire. If you haven't, do it and give the car another chance. I went through a rear set of brakes super fast when I first put mine in and had not cut the wire yet.

I had Z1 port the upper and lower. Descent gains were made after dynoing.

You haven't reached the limit of this car. You just had the wrong expectations from what mods you were doing. Just like the KWV3's, that's not what you needed to get. Look in the track section/suspension section, track rats have many good things posted in each. There has been many knowledgeable folks post threads in each. Some are still here, some are not.

No the next day I backed out of the garage in a straight line and not loud but noticeable clunk, clunk, clunk.

I assume this is because the fluid is fried as my garage stinks like diff fluid something fearce!

JARblue, DarkJak and Hotrodz like this. __________________ \|RIP\|6spd-sport\|OSG-LSD\|XP8\|RBF600\|Eibach Sways\|RE-71R\|FI-34Row\|Gen3-CAI\|Yaw P.S.\|
