Finding of limits of 540i Supercharged with superbad gasoline...

[dovlet]

Currently decided to open thread about my problems with my car due to bad gasoline. This is 4th or 5th engine with low compression 8.9. Just 20minuets ago during making the logs for FRANK from TTFS, all my coolants went away on ground. Hope nothing happen with my engine. Some photos below.

Yeah, nothing. Just filled up water and tighted with clamps .
So far is ok, also tried full loading after. So far is good. Oil level is also stable. Tommorow will change hose and coolant.

[philly98540]

Ok damn. No damage, so that's good. Glad you started a thread .

[99Bimmer540]

Can't wait to Turbo or supercharge mine this spring. Court and fines broke my bank. LOL Is there any manufacturer out there that does turbo headers for the 540?

Mine is 210mm. Lsd is 188mm.

[tptrsn]

I have never been completely up to speed on what cars have the 188mm LSD in them, but I think it is MANY, and the cars that have the 210mm diff are few. That's why it is difficult to find an LSD for our cars unless you go with an E39 M5 diff, or get an aftermarket one like a Wavetrack or an OS Giken. Both very expensive.

The cheap option that will give you 100% predictable traction at all times is to have your open differential from your car welded solid. If you have a shop around that deals with drift cars at all, they will know how to do it. It's very cheap and simple, especially since you have your diff out of the housing.

Bro, my self and couple of my friend having a deal with drag cars. Here is very difficult with modifications. I am an engineer, one of mine friend is juvelir, another one is IT. So, when we gona to do any mods we are preparing a lot of meassurments and instructions for people in workshop. In other case they do not know what to do. Unfortunately that my destiny and sometimes i want to open my own shop to make mods but when i visit bank in last days of each month i changing my mind)))))

Well, it doesn't require fantastic welding skills to weld a differential if you want to try it yourself. Quite easy actually. From each side of the differential, just weld very thoroughly at all 4 corners where the side gears meet the pinion gears. That's really all that is needed.

Of course, clean out the diff first with NON-CHLORINATED brake parts cleaner or acetone or something, and then protect your bearings from getting weld splatter on them.

There is orher way. I will try find tommorow another reducer 188mm and will try to fit it on my car. If i will be success then will be on 188mm reducer with lsd.

And now time to think about piping and tubes. Is that good point if i will use hose elbow from Sc 2.75" to 3"? Or it is better tube?
Phill. If you see this thread please advise on pipings and tubs details.

Bro, i did not find pipings and tubings details in your thread.
I am interesting on next:
1. What did you use to switch sc and straight hose or tube to IC?
2. Is our throttel 3.5"?
3. Did you use aluminium pipes or only silicon?
4. What is the name & size of fitings which supply water through it to your IC? Attached

Moved your post to your thread. Did you read p 15 of my thread? Enough details there for my air side piping. Your TU, so yours will be a little different. You have to measure and build it yourself.

[dovlet]

Tqvm philly, so far everythings going smooth. Ordered cold sparkplugs ngk bkr7ix 2667 & tial pink spring for 1.5psi.
SmartSelectImage_2017-11-29-21-05-23.png
The next step is installing all of them. Also, very interesting on standalone ms3x or vems.

[philly98540]

Gotta luv amazon!

[dovlet]

Philly, what do you think about 3.0 pulley instead of 3.25 which i currently run. What do you think about pressure? My calculation is 12.5psi. If 3.8" pulley 6psi, 3.25" is 10psi & yours is 16psi then it is leaner increasing if crank pulley the same. I got 12.5psi. Is not it bro?

Just ordered second stage grid clutch. You opinion gents on this?SmartSelectImage_2017-11-29-23-38-41.png

[philly98540]

Might be 13 psi.

That clutch will likely slip with a stock pressure plate.

Ordered almost everything for water to air intercooler except heat exchanger. Thinking about this one which no need aux fan. What do you think? Or it is better to order radiator where i can put aux fan?
