LSD for AutoX

[F34R]

Use redline. why would anyone reccomend Royal Purple? I guess because it's cheap.



yet you were telling me I don't understand AFRs? ;)

also, chinese headers and exhaust doesn't sound far from stock to me. Unless you open up the motor, it's still basically stock.



That's because they were manufactured 5 years ago and are hard as rocks by now. :(

Royle purple is 13 bucks a ltr, I did not think that was too cheap. I'll look into redline and see what that runs. I was going to use that but it was not offered in the local speed shops.

I understand them, just not enough to argue about them and put all the correct info and facts down. I should have rephrased the CAI from the start. Sorry for not being 100% on all needed parts to make it worth it.

Since when was MSDS headers chinese? I also have a complete welded exhaust from the headers back to a glass pack, my father has 28 years welding. My Uncle is looking into a exhaust bender, so maybe I can have a slick bent exhaust! (He owns and runs a garage)

I have not done anything to the m20s internals. Yet it is still not stock, I know this because my brother still cannot beat me with his 325is. In any gear or off the line(eta bottom end baby!)

So don't assume you know what I have done to my car. I know it is not a monster, but it is making more power than a stock eta. I only buy good shit for her too.

I wish i could find some photos from my sunday runs, As I was slow and sideways for most of it, but I bet the e30 looked really cool coming through the finish line sideways.

what, Nankang M&S all seasons? :p

I love my ES100's. Way more traction than what I used to roll on.

And with colder air it is more condense and will therefore add more o2. I am not 100% on the effects, I just know you put down better times in the morning than in the evening. I could go read up and know 100% on the effects, but I really don't care too much.

Yeah... I just love those ES100's... no matter how many times I spin, they don't seem to wear down at all...

Yeah but it is a little different when you are on a auto cross course, as the entry speed is a lot higher than on a street so even with an open diff you will get sideways.

I am on an auto-x course... that's pretty much the only time my car gets driven... :(

I spun my Spitfire (no LSD) a couple of times in auto-x as well, but it seems the E30 goes sideways much easier.

Was wondering what fluid would you guys recommend I run in my newly acquired LSD?

Redline 75W90 LS (not NS) or Mobil 1 75W90 (which I was able to find at Kragen, make sure it says it's ok to use with a limited slip diff as I'm not sure if they have two different kinds).

And with colder air it is more condense and will therefore add more o2. I am not 100% on the effects, I just know you put down better times in the morning than in the evening. I could go read up and know 100% on the effects, but I really don't care too much.

Well, you should, as that is kind of Car Enthusiast 101 material. IATs are important.

Royle purple or Redline

so no comment on denser air making more power because "it burns faster?" ;)

the stock airbox and AFM are *just the right size* for the stock motor. Do think BMW engineers are retarded, and they didn't realize just making a bigger hole would give the engine more power with no other drawbacks?

So you've made the airbox and AFM less restrictive, what about the throttle body, intake manifold, head, cam, and exhaust? These things are all designed together. Peice meal upgrades are a waste of time, which is why swaps are so popular.

and I wasn't arguing against a MAF. Also gains with the MAF include tuning, which is where most of that power is coming from.

what is far from stock btw?

Indeed, everything is in hand with the others.

I have headers that dump into single 2.5 muffler, cat delete and a borla type muffler. CAI that is into the fender via a modded AEM tube.

I had a ride in an e30 with the same type of upgrades as mine but it had a miller MAF and war chip. I wanted to get it once I got home but...cost too much to waste on since I am almost done with my m50tu.

I was not arguing over the miller MAF, just letting others know what it does.

And with colder air it is more condense and will therefore add more o2. I am not 100% on the effects, I just know you put down better times in the morning than in the evening. I could go read up and know 100% on the effects, but I really don't care too much.

I would tend to agree with this. My car does have the LSD rear, but with the shit tires I have (205/60-14 ES100's)

lol, what are you talking about? Those are awesome tires! :p

if I try to get on the throttle too early or too hard, I come out of the corner sideways at best, and backwards at worst. Even with a stock M20 with only a cat-back, the margin for error is a bit narrow.

The story's different when you're already using most of your rear tires' circle of grip. It's just a lot less predictable.

Never stated on a stock motor. My m20 is far from stock.

Wait, so you're talking to someone with a built motor (I assume that's what far from stock means, right?) and the first thing that occurs to you to say is... "hey you should get an intake"?

[CrazyB]

LSD will help, quit a bit, but you'll need to be more precise with your throttle input, or your really going to be sliding.

The fact the car is loose w/o a LSD is a bit odd to me. The past RWD cars I've had w/o a LSD, the inside rear tire would lose traction and spin, but only if there was limited traction overall (wet road) would the rear end step out.

Well found a local 3.73 lsd in good shape, will try and grab it today. And will see this Sunday how much of a help it will be. its will be interesting as I will be running at great America again this Sunday so it will be nice to really tell the difference between lsd and open diff on same pavement.

sweet. I'm sure it will be a huge difference. Nothing worse than an open diff, except a FWD car with an open diff and unequal length halfshafts! :p
