Thanks Bat, she's nearly a rolling project now haha!

Mot is passed

Taxing her tommorow.

Note the whining? It's the fuel pump.

Think I've shagged it. Not only should it be ran as a push pump not a lift one but it should also be ran with the filter post pump not pre pump! Plus I ran the tank almost dry the other day!

Well I did buy a cheap pump last year knowing it would be highly likely to break by my hand. Least it wasn't £150!

So I've purchased another cheap Bosch 044 style one today for £15 and some more hose and some spare fuel filters.

The other reason I think the fuel pump is shagged is that she won't happily go over 50without leaning out. Anything more than 1/3 throttle makes her lean and the acceleration enrichment was set to standard settings yesterday. Today I tweaked it to a constant, under medium acceleration she is surging. afr goes to 12 from 14 to then spike up to 20 (lean)

So new pump and some replumbing is planned. I'll hang the pump from the subframe so it'll be gravity fed better and run the filter post pump as recommended

All for now!
Lawrence

Cheers for the comments guys!

 

She is still working. Together I have driven about 25 nerve-wracking miles in her, some with a support car! She gets some weird looks! Especially the lady in the range rover who I pulled up next to in the garage! Though she was having a panic attack when mini backfired!

 

So she has been taxed from the first of august!

 

However we finally got the keys for our new house on the 3rd! Meaning she has taken a back seat (not my choice but lets not anger the partner quite yet!)  

 

Off topic, new garage is pretty small but has rafters, there will be a garage build integrated to this blog  with a roof mounted engine hoist sometime in the future! 

 

So fueling,

Yep I had buggered it

 

Removed from where it was

holes made in the boot

new location under the boot floor. 

43800194051_e4491a025b_z.jpg20180801_161918 by Lawrence Balls, on Flickr

there is good clearance from the exhaust by the way, just hard to photograph

and in situ with the new ceiling light mount

43863041372_f0b1930285_z.jpg20180802_210426 by Lawrence Balls, on Flickr

still need to redo a bit of wiring as the ceiling light doesn’t come on with the door lights yet but its easy to do

 

So shes running very iffy.

 

When I changed the fuel pump and fuel filter was relocated to the bulkhead (and filter changed) she did run ok.

 

Idle and minimal throttle are completely fine.

 

Anything more than minimal and she is still leaning quite a lot. I think ive tuned up to maybe 30% of throttle opening currently, any more than that and she leans to 22.4 on my afrs! 

 

Cooling. Ironically she was fine coolent wise on the way to the mot and even sitting there with high revs for the emmisions didn’t overheat running on just water. But now ive changed the coolent she is overheating. 

 

I think the system has an air lock. Also the way ive plumbed the idle for the ITBs may be interrupting the flow of coolent? Not sure. So this morning im planning to try and bleed the system again. If this doesn’t work ill temporarily clamp the ITB coolent line and see if its turbulent flow in the rad causing issues which I suspect it may be!

 

That’s all for now

So people, 

 

Time for an update!

Last update I was doing some tests with the cooling system. The way the itbs were plumbed meant that with driving the coolant bypassed the thermostat before it was fully opened and made the engine start to overheat. 

 

So I clamped the line and did some runs. Solved the problem.

 

Then I moved mini to her new home (and my mattress!)

she fits fine.

44153130861_0d522f7c81_z.jpg20180818_102713 by Lawrence Balls, on Flickr

 

All cleared out for some painting

44152871311_02f693e1a3_z.jpg20180818_120346 by Lawrence Balls, on Flickr

 

racking put up

30286385288_79a7c66a24_z.jpg20180818_172147 by Lawrence Balls, on Flickr

 

plenty of room

30286202378_bac0c88a85_z.jpg20180818_184628 by Lawrence Balls, on Flickr

 

not sure what to do with my bike yet tho. May park her outside and get a cover. Push bikes ill hoist up to the ceiling with some rope and eyes. I need to deck more of the rafters out. Planning to keep all my spare spares up there and the used spares down in my roller cab.

 

Keep an eye out for more garage updates!

 

Making my mods to the cooling system

blanked the ITB coolant feed off

44110295072_11d45f3ece_z.jpg20180820_144331 by Lawrence Balls, on Flickr

 

rejigged the radiator fan

29220799827_ba111ee6eb_z.jpg20180820_182046 by Lawrence Balls, on Flickr

luckily I could spin that top protector bar and use one of the rad mounts to mount the fan on the back. Its not a pull fan as apparently that’s the most efficient way of removing heat for a front mount rad. 

 

Ive also lowered the rad and straightened it up.

 

Plan tomorrow is run it up to temperature and bleed the system, hopefully she will get rid of the heat better. 

 

Today I took her for a 30mile run back to my parents for more garage stuff

15 country roads

15 main roads

 

on the country roads at 40-45 ish she sat happily at 88degrees. Boot it and the temp would rise.

 

But on the way home on the main roads at 45-55 she gradually crept up.

 

Ive also got this gap

43252951605_5a5d11f148_z.jpg20180820_182052 by Lawrence Balls, on Flickr

So ordered a 7inch fan for that space. 

 

Ill update again soon! Thinking about making some aluminium ducting to control air flow in the engine bay but not sure if it is worth while?

Time for a little update.

Shes running pretty well currently. Since i swopped the fan to the other side and adjusted the radiator she is holding a steady 88degrees even when booting it. In traffic she does start to get warm so i will fit that second fan when it arrives but its looking good. Ive also ordered some heat shielding and i will make a better sheild between the exhaust and the rad as well as some ducting to direct air.

Currently im just driving her about town, being a bit yobby with the exhaust in car parks and tuning the acceleration enrichment more. Also doing more of the garage build. Currently decking the loft part but im collecting more parts this week and potentially my bike also.

All for now
Lawrence

Great to see the car being used at last :proud:

Another fan may cause some flow problems as it will cover some of the radiator and you may find the fans are coming on more often. On my camper I've ditched the mechanical fan and fitted a lekky one but the temp would creep up until the fan cut in. I fitted a small bike rad (KTM 125) in the heater return and now the temp sits happily a few degrees below where the fan cuts in which now only operates in traffic or after a hard run

Cheer for the comment!

Trouble with just the one fan is that it would cool her if needed but not very fast. Now ive modified her she runs at 84degreess on my post rad sensor. Not sure on the block one as megasquirt wont read it.

 

Decking out the garage roof

plenty of space for spares up there!

 

Second rad fan fitted

44327077191_1791b7fb90_z.jpg20180828_173739 by Lawrence Balls, on Flickr

 

high quality braket made

44327077661_c2f53a22fd_z.jpg20180828_173727 by Lawrence Balls, on Flickr

 

rad spaced out a lot more now. 

44279291012_730b7c019b_z.jpg20180828_173722 by Lawrence Balls, on Flickr

 

when I bring my welder over ill make myself a new bracket to support the whole of the bottom of the rad

 

how the garage is now

44300251662_11ddc283e8_z.jpg20180829_181117 by Lawrence Balls, on Flickr

 

plan is to build a great big workbench across the back of the garage using old kitchen worktop that I have. Ive got a nice big vice to fit to it too. Im going to make the bench really sturdy and wall secure it etc. 

 

ive also managed to get my bike in the back garden too. Be interesting to see with the gf says!

 

And a little shot of her in the multistory

So from before the issues were

>edis not working

>right front indicator not working

 

I took the megasquirt apart and discovered ive no idea what I did to it before, mini was therefore running a fixed level of timing at 10degs

 

So dismantled and correctly wired up

daughter board removed

43903911894_e7fd6eabd5_z.jpg20180903_175217 by Lawrence Balls, on Flickr

 

ive left the spare drivers on the board as im planning to go to COP in the future and rid myself of EDIS as its just one more thing to go wrong. I also want to upgrade from MS1V3 to either MS2 or MS3 depending on finances. 

 

Meelie had a look inside too

29684557967_f8bf86ca2d_z.jpg20180904_161747 by Lawrence Balls, on Flickr

 

and the girlfriend took her for a drive to the local tesco too

30752652808_599d2ce725_z.jpg20180905_193133 by Lawrence Balls, on Flickr

with a look of panic saying “these brakes are rubbish”

 

Also fabricated some restrictors for the ITBs too

30752654088_8c5b3ab308_z.jpg20180911_142746 by Lawrence Balls, on Flickr

 

I also did a bit of wiring in the garage ready for my workbench to be fabricated

Good afternoon people. 

 

No real updates im afraid on the mini front! As readers of my build will know ive moved house and that means I cant use my parents cars anymore should mini not work.

 

Mini doesn’t work. So ive had to buy a different car. 

 

Bench finally sorted

44926112824_5a68deba78_z.jpg20180928_171901 by Lawrence Balls, on Flickr

 

new oil leaks

44926113104_c3c4b2d4e8_z.jpg20180925_164847 by Lawrence Balls, on Flickr

 

new battery for mini

45600649222_b7ebb2af52_z.jpg20180925_152613 by Lawrence Balls, on Flickr

 

driveshaft gaitor failed

44926112584_9f51ae0d7f_z.jpg20180925_164902 by Lawrence Balls, on Flickr

 

But

 

Engine rings have not sealed properly and/or my honing was bad and/or trying to tune a newly built engine on ITBs was a bad idea and/or my megasquirt just cant cope with ITBs (ms1)

 

So- I need either

New engine and new megasquirt

Or

New engine and fusion fabs mani and run current megasquirt

Or

Donor car with ecu and fusion fabs mani

 

Either way mini doesn’t work and hasn’t for over a month. Now I have been motorbiking to work which as people will know isn’t practical in the winter. 

 

So ive got a winter run around/ project car ;) bike is going to live at my parents over winter.

 

Mini is currently paused – im looking out for 1.3 engines/ whole car locally. 

 

New ride

31778690418_710ff41163_z.jpgreceived_298301927688293 by Lawrence Balls, on Flickr

 

e46 330ci with all the mod cons! See any other projects for this project and ill update mini when I get the engine 

 

all for now

 

Lawrence
