Yeah that male actor has a serious case of the come downs and on a mission to get his next fix. Hmmm maybe there’s meth behind this wall, let’s cut it open with this chainsaw.

Still available?

Sold them a wee while back. Forgot to update the listing!

Another issue fixed, the rear rh door wasn't opening from the outside, flicked the kiddy lock off and hey presto, chucked some lube at the mechanism to stop it squeaking and job done.

This car is one of what I assume are the majority of these, suffering from decades of neglect and ignorance, but has nothing seriously wrong with it. Its a shame that most of them will end up at wreckers because people aren't prepared to spend a little bit of money every now and then.

Yep so true. If it weren’t for pickapart and Zebra getting so many e39’s I would have never bothered with the old touring I had.

Such a nice looking car but tbh they scare the sh*t out of me haha

More new goodies, $470 worth of gas struts for the tailgate!!  Investigated the handbrake issue, the shoes have plenty of meat on them, but have  big grooves all the way around and cracks across the surface so it will be getting new ones, also found a boost gauge in storage, so it will get that as well

More cleaning inside, starting to reassemble the interior, still needs a new drivers seat belt,  but have started the wood grain delete...

I've got a gen bmw handbrake shoe kit i'll donate to the cause also. Thought I could use for the M5 but appears not.

Yeah surely some fault messages would be there after it goes in to limp mode. Best to scan it as soon as it exhibits this behaviour though.

I had a similar issue in my old m5 after doing clutch, the o2 sensor connectors were plugged in front to back. You mention the o2’s were replaced but was the exhaust dropped before it started going in to limp for maintenance/repairs?

They are, a thorough wof inspector will call you out on worn bushes and ball joints however as long as the shocks aren't leaking they seem to get through when in reality the shocks are pretty much poked before 100,000kms.

Check pick a part.

Glad your cyber ego hasn’t deflated too much.

Pen is in the mail... ?

Deep Breaths Dave...

No we’re sharing our experiences on experimenting with iat’s and how that has affected engine performance. That article you’re harping on about does make sense but I don’t think it’s entirely true and as mentioned several times, a measurement tool i.e a dyno would definitely confirm what effect iat’s has on the m54’s engine performance.

No, the last time I wrote to BMW was in in the early 90's and I got a invite to their Mt Wellington headquarters. That was cool of them to do. They send pens to people they don't have time for.

And I don't disagree with their technical documents but we've already established that. It was a suggestion for people like you who claim to know better than BMW themselves. ?

 

What colour Bimmersport pen would you prefer?

Something tells me you’ve got a box full of them.

Is all the suspension original?

Yeah engine under tray off and a pressure test. 
 

Can you smell any coolant while driving?

I'd be very cautious buying any car that has a S63, the pistons are common to explode and now hearing that the rod bearings are becoming another maintenance item, if you had the deep pockets i'd go ahead but if you were to have mechanical insurance make sure there isn't a cap on how much you can spend. A rebuild of the bottom end cost 30k+ from memory.

Exploding pistons as a result of shitty aftermarket tuning?

Bumpity bump

Well to anyone that thought TL;DR for this, Dave found comfort in a paragraph he found on the internet. 

He also accepts himself.

I found this on the MS43. I think really the only way is to do some data logging or dyno testing to see what effect the iat has on fuelling, timing, engine power.

You guys are just making stuff up.

Making stuff up? 

I’m sharing the results from my experimenting on a dyno with s62 iat’s and made the assumption that iat’s can influence fueling on the m54 as well, but perhaps not the case with the ms43. (M54 engines).

I'd like to donate to the cause, I've got a set of facelift corner tail lights I'll give to you next coffee meeting @aja540i

I think you’ll find there’s a difference with the iat disconnected, certainly on a dyno measuring afr’s. This is absolutely the case with the ms52 dme programming and suspect also true for ms43 dme’s too.

I dunno the evo in those clips couldn’t seem to pass the 130 on the initial straight. Off the mark might be a different story though. Looked like the evo needed some Tweaks. Loads of understeer.

Let the fun begin!

This is a very interesting topic.

A good test might be to swap the stock intake back in and take the same readings and see how much different it is.

 

A long shot idea, but would a cooler running fuel like gull force 10 have an impact on intake temps?

You could also experiment with heat guards on the headers etc

I'd imagine Gull force 10 would have an impact on combustion temperatures rather than the fresh air being drawn in. IAT's or "sucked air temperature" is the temperature of the air being drawn in to the intake manifold before it gets used to combust.

If IAT's are cooler then the dme adjusts the fueling and timing accordingly which results in more efficiency, more power and torque. It is the MAF which calculates how much air volume is being drawn in to the cylinders.

A few years back I ran an experiment on a dyno by putting one of the M5's maf's (that is used also to measure IAT's as it has an integrated sensor) in the fridge for 10 mins in between dyno runs. The result was about 10rwkw's more peak with IAT slightly over ambient vs about 30deg C over ambient on the first run.
