What have you done with or to your M3 today?

Cleaned off and fired up - Congratulations mate!

Yup, long day to install - me and a buddy did it in about 13 hours. Included:

plug change
oil change
fuel tank breather change
SC install

The night before, we changed the starter. That was a full 5 hours in and out. Started the engine to make sure it worked before we tackled the SC install - that added some time but not too much. It is a PITA job - the SC is easier (other than the hose connections...).

So far, pretty happy with the kit. One gripe is that the barbed connections on the front mount heat exchanger are too big for the supplied hose - and they are sharp edged. Almost impossible to get the one side on - much foul language was used. Also, and perhaps I did something very wrong, we had a hose left-over after the install. Cooling loop is all buttoned up and works great, but I still wonder why we have a spare hose. Mystery.

Oh, and they did not include the bolt for the ground wire - I managed to adapt and overcome this.

And as I do work on this car, it seems to me that the previous owner did some odd things to it as I have found a few fasteners in the car that are NOT BMW stock bolts. In strange places...

I removed parts for my e93 M and did some chopping.

isnt a plug change time consuming?

No not at all! I rather do a plug change on an s65 then any front wheel drive v6, especially a Chrysler/mb V6 van

Hardest part of a plug change is getting the coil packs out. And that is not that hard. The S65 is super easy to change plugs, especially with the plenum off.

I still hate torquing spark plugs. Scares me every time.

What takes the most time is getting the old oil back into the Red Line bottles to send back to FCP. Such a tedious PITA!!

I use this to transfer oil into smaller volumes. I've even used it to extract oil through a dipstick tube when the guys that changed my pickup tube overfilled by a quart.

Sounds like a massive job in total, big congrats yet again mate. Verry strange with the hose left over - double check with the supplier?
Oh, and I've realized that the startermotor is one piece I love to not have to replace...

For the first 350KM, I have to drive it under ~6K and no WOT so... I do not know yet. :P

I sure hope it will be an animal - we will see.

Cheers,

Congrats on the install. I did the Harrop install in my garage last summer, with a buddy joining me on the major work day. I don't recall having extra hoses but definitely ran into some quirks like having the wrong number/wrong size of hose clamps. Nothing major and that first start up was so satisfying.

I don't recall having a break-in phase but perhaps I spaced it. I wonder why they ask that of you with the G1.

The biggest detail I overlooked and had to return to was the proper tightening of the clamps on the 8 throttle body boots. We ran into an issue when all that was coming together, got distracted, and they were only hand tight. I came back a couple weeks later with a precision torque wrench and got each of them down to 6 Nm and was impressed how much I had to wind them in. But then I went back a couple weeks later and repeated the same process, again finding that they weren't as tight as I left them. The risk is boost loss - and irregular boost loss at that so if you aren't getting what you think you should - look there.

The one thing I think all of these kits should have and don't is a boost and IAT gauge. I installed a P3 gauge a while ago and followed boost for a long while but now I monitor IATs more regularly. The risk with supercharging is detonation leading to engine damage or failure - and it's a small risk but a failed intercooler pump would probably go unnoticed and could put you on the edge of detonation through rising IATs. It's the German coming out of me....I....must...have...more.....data.....Everything will be better when I have more data.....

It looks so much lighter now than other convertible E93 M3s.

With the Harrop SC the intercooler pump and the boost bypass actuator valve are on the same relay circuit. So if the pump loses power, then no boost, but as you say - IF the pump were to fail internally, while still having power to it, then things could run hot. In the summer, I keep a keen eye on oil temps and run 3 gallons of 105 RON E85 with the rest of the tank being 93 Octane Shell V-Power (for an effective RON of 97) to mitigate knock and maintain horsepower in the hot humid South Carolina summers.

I am very happy I have the P3. I have been looking at boost but not IAT much. I have not really gotten into the throttle much anyway, plus it is cool here right now. But thanks for the heads up, I will look at IAT.

As a controls engineer, I really want to know the running status of the inter cooler pump. I was thinking of how I could measure pump current and put that into the P3's 0-10V input. Easily done with typical shunts and mV/V converters, but it would be ugly. I will have to keep looking into that!!

Hit something in the road, maybe a tool box. No more oil pan, no more oil in engine, maybe no more engine?? 🤬😭.

Sorry to hear that. Definitely bad luck but on the flip side it's certainly one way to have the insurance pay for new rod bearings or maybe a new engine. What year is the car. Advise showing insurance company some of the latest Bring A Trailer auction sale values for E9X M3s in case insurance adjuster tries to low ball your claim, or total the car. Good luck. Keep is informed. Lots of experience and knowledgeable folks here who can probably weigh in and help if needed.

Well…visible damage includes nearly football size hole in the pan, sub frame reinforcement plate, chunk of my euro bumper pulled off and the center under tray destroyed. It looks like I got hit by a torpedo. Of course, Progressive trying to weasel around things (not wanting to cover new locking bolts, nuts, cleaning off all the oil, alignment, oil, filter, cheap aftermarket bumper, let alone rod bearings). Going to be a battle as usual.

Jeez, that's awful to hear about. Such bad luck. I do hope things improve for you and your car. That doesn't sound very "Progressive"… Perhaps that insurance company should be renamed as The "Woke" Insurance company…

Ordered an E. Race black series for the e90. The ultimate waiting game begins!!! Can't wait to hear it!

Changed my MAP sensor, it was hell getting to it (at the back of cylinder #8) ,but this lil tool called the "Proxxon Rotary Ratchet made every hidden bolt so much easier to deal with. This is MUST have even for the occasional diy'er. Its like a pepper grinder that spins loose no matter witch way you spin the handle. Stanley makes one but it doesn't have spot to attach another ratchet to the end of the handle for those tight bolts in tight spots(see pic).


Ok enough of the tool, I changed the map sensor due to sporadic idling and poor gas mileage I changed just about everything thing else and this seemed to have done the trick.

I had a P3 and it was cool, I just didn't like the glare it put on the window when I needed to look at the side view mirror.
I have since installed this and it gives me all the information on one screen. It also has an input to measure what you like. This one is made by WEngineering. It also let's you set warnings ....like IAT's, temp etc. Reads and clear codes, it's a cool display

First wash! (LOL)

That tool is awesome. Looks like it could be helpful for starter bolts.

I'm due for one too

Reported a claim, some piece of sh*t hit my car while parked. Pushed in my turn signal on the passenger quarter panel and scrapped paint from the fender to the start of the passenger door. Looks like they were backing into the spot, noticed they hit me, then pulled away.

I know they won't be able to match paint because it is 12 years old and partially faded. So probably will need a full respray.

I should have done some more research... Oh well, perhaps in the future I will upgrade the P3.

I do like my P3 too. The glare on the mirror at night is a little lame but not terrible. I would love to have a little more information. And why is it so hard to get oil pressure? Grrr...
