Emma Watson and 2 E34's (Low Mount Turbo M50 Project)

[varg]

Nice. I missed this one, you and I tackling parallel turbo E34 builds with totally different paths. Sucks that you had to fab that crossmember, somehow the AL ZF crossmembers were still available new and fairly cheap last year.

I think your brake booster check valve is backwards?

Nah it's good. There's an arrow on it, visible from the front, hard to screw up.

Because this should be on every page.

A shot of the lightweight flywheel from ClutchMasters. Working on a diff rebuild for the car as well. Using cryo treated 3.15 ratio with a 40% lock clutch pack kit from RacingDiffs. Old clutch plates looked good in the carrier housing. Waiting for the proper side shim sizes to arrive and we should be ready to install the diff and drive the car finally.

Read your recent updates on the last few pages, looking good!

I'm going to go back and read from page 1, purely for the Emma Watson pics of course. 😉

Moved under her own power this last weekend... Clean finally after 8 months

The build continues as we work out kinks and smaller problems. As of now we are up and running on 10psi. Engine tuning has been complicated with the Link ECU. A very powerful controller has some downsides (learning the software) has been tedious. We had issues with dashpot settings and engine idle undershoot. The car was dying off decel, hunting ect. Finally got that sorted with idle base position settings.

Screamer pipe setup I had going is fully out now due to the fact that is sounds like complete shit. As soon as It opened up the first time I instantly hated it. To fix it I fabbed up this setup to pipe it back into the exhaust.


Engine bay is done for now. I need a coil pack beauty cover. If anyone has one let me know.


And now the best part so far. F30 340mm brakes. Should be fun times.

Calipers have been overhauled and painted. Waiting now on special brake lines to finish the job. Very nice overall outcome. I am pleased with the results. In the coming week I am expecting my set of throwing stars to arrive. 8 inch front 9 inch rears should set the car up nicely.

Here in the lower left of the wheel well you can see the oil scavenge tank I fabricated. We have a -10 inlet from turbo drain with a -8 fitting to the Turbowerks scavenge pump mounting on my passenger side shock tower in the engine bay. The clear line tucked inside the wheel well is an air vent line to regulate the small amount of vacuum the pump creates. I used plastic vacuum fittings to reduce the size at the end of the vent line to get the right amount of air flow. The system was a pain in the ass to build but it works really well!



IMO all turbo builds/ anything with significant engine mods should have a fire extinguisher just in case something goes wrong. 2lb simple setup here gives a nice touch. Clean and out of the way.




Rear calipers are getting overhauled now and will be color matched to my sparkle plum paintjob. It looks lame in normal light but really pops in the sun. Once my wheelset arrives from Russia (probably funding the war effort w/e) we will be back on the ground and ready for some more testing but only after I tackle all replacing all 5 shift detents in the transmission... Not looking forward to this but it must be done. More updates on this to come as it is the first time I have done one.

2 of my dream wheels have arrived. Still waiting on the remaining two to arrive.

damm those turbines look fantastic.

The style 21s are going to look good on your car especially with the brake upgrade. That's something that interests me but I have no budget for it right now since my block is headed out for a bit. I'm glad to hear you ditched the screamer pipe. Yes, they do sound like garbage, and M5Xs do not sound good at all anyway uncorked, especially without equal length headers. Screamer pipes also make it harder to hear detonation so I eventually stopped tuning cars that had them back when I was a tuner.

Agreed. I paid way more than I wanted to for this set of wheels. Insane how expensive they are now compared to 5 years ago. I have been working on the knock control feature in the Link ECU. I do believe I have some slight detonation right around 8-9 psi but my knock control has been turned off. This will be the first time I've tuned an engine with this feature. My ignition table is no where near dialed in yet. Pulling some time away will be the first step once I get trans back in the car... Always something...

[varg]

The best way I found to dial the knock control in is with some "det cans" and the lightest wastegate spring you have (or no spring at all). If you try, you can induce detonation even at moderate load, and tune the thresholds with that. I have done it before by just progressively adding timing in the 90kPa range while right seat tuning but it wasn't a frequent task because it's quite rare that people have knock control set up in their aftermarket ECUs. My plan was to do so with a quarter tank or so of 87 and a bunch of extra advance. My old det can setup with the harbor freight sound amplifier is busted though so I need to make some new ones.

Started working on a distilled/alcohol water misting setup for the Intercooler while I am waiting for other parts. Always wanted to do one but never got around to it on my e30. The Volvo cooler is very large (bigger than the radiator) but relatively thin. I have a pump and some hardware on order to do a clean install. There will be a small contact switch integrated into the shift knob for manual control and I may have the Link control this based off boost pressure. I like the idea of manual control without having to move my hands off normal positions to cycle it on. Ill use a momentary switch to mist the intercooler before (or during hard pulls) Here is the Ebay tank for $29 mounted in the trunk for easy access. It should hold about 1.5L. We will see how much I have to refill it. The pump will be mounted further up in the trunk and the feed line will go on the drivers side inside rocker up into the engine bay.

More updates to come.

This is some great work. Makes me miss my E34 530iT quite a bit. E34s deserve more love, these days.
