Ok I feel like ever since I wnet turbo, I have been paranoid about my car, now my new thing is there is somewhat of a "Whine" coming from the rear differential. Once the radio goes on, I can't really hear it, but since I got the Turbo I have been WOT a lot, no to redline, but hard off the line (No clutch dumps, or RPMS above 2k when I start off in 1st). Differential fluid has not been changed in over 45,000miles, (going to do it tomorrow) I read on here by someone that 75w-90 is no good for 300+WHP. I have Mobil 1 75w-90, I was going to use this. I really have not been too hard on the car, but I feel with the introduction of the new HP maybe I broke something in the Differential. I will be going to a Honda Dealership tomorrow for one of their mechanics to come for a ride, maybe they can help, but will this Mobil 1 Differential fluid be ok?


PS Wouldn't a clutch go first, or at least be slipping before I blow out my rear-end?

I have 70,000miles on the car

I've been using the recommended oil (I believe 75w-90) in my differential from NA to over 500rwhp turboed without a hitch.

ok, I hope I am being paranoid but form what i hear, a differential replacement is up near $6,000 ???????????????????

Most of my miles are highway, the Greddy kit isnt that powerful, I don't think its too much for my differential, but I do seem to hear a whine

i have run, redline, LE, Mobil, and whatever was in the car when i bought it. All with 300+ ft/lbs of torque with no issues. That includes a launch at Thompson in Ohio with VHT and a 1.8 60 ft which i won't do again! Although no bits of metal or large chunks on the magnet part of the plug when i removed it.

THe LE is supposed to be closer to what honda specs the gears out for, and when i put a few more k's, ill put that back in my diff!

Not to be a dick, but are you sure its not just tire noise?

I'm guessing the "Whine" you're hearing is coming from the fuel pump.

Spec_Ops2087

If the whine is constant and does not change with RPM or throttle load, its the fuel pump as enthralled said.

Prob fuel pump. But be sure to check your diff oil level (you should be able to stick your finger in the fill bolt and feel the fluid level) since you changed it recently

Enthralled

btw fuel pump noise is normal.

Even if it's the diff, you can get another for 4-6 hundred

But yeah, larger fuel pumps are LOUD!!!
