Greek Landrovers and Megasquirt progress

Graham Reeks doing a spot of servicing on the 'Bench'







A few detailed shots of the current layout of my EFI setup. I was lucky to find a Falcon air trunk to allow a neat route to a remote KN up in front of the radiator. Not happy with the ignition lead lengths (too long) and just need to wire up a few sensors (TPS , coolant IAC and inlet air temp) probably take the loom through the inner wing as much as possible to keep it uncluttered. Need to set up the wideband O2lambda and enlarge the bulkhead hole for a discovery throttle cable....then its ready to fire up :-)

Classics of Perth rush hour

A few happy snaps from my drive home over the last day or so....

Valiant coupe ~1968 .... basically a Dodge Coronet?


Ford Futura Sprint? 289 V8 ~1965-66



Marcos !!!!!

Rover 2000 auto :-)

And a nice Shadow II complete with a pair of golden bollox... classy.

Update on TSOA day + Megasquirt

Been a bit busy and not really had enough time for everything.

TSOA national went Ok until my diff cried enough. Maybe my guest driver summarized it better as an outside observer?

http://ofnofixedabode.wordpress.com/2009/11/10/tasting-paddles/

My best time I got was literally my first competitive lap in the dry at collie in over 2 years before I was held up a bit by having to negotiate slower cars. It was also a personal best at 56.2sec but I had no chance to chip away at this time over the rest of the session (a 55sec or better lap was definitely a probability as there are a few corners where you need to build speed as you get confidence in the grip conditions).

Humph's PI was howling and he started in the mid 57's and got down to 56sec dead by the end of the third session. The new hybrid cam concept we are trialling definitely has improved power and torque and if anything, Humphs engine has benefitted most as he runs a 11.4:1 CR versus my 10.8:1 and the new inlet cam profile with a closing timing of 77deg ABDC needs a high CR to get the most out of it.

Any it was a good day marred only by a nasty finish line roll by a Victorian TR8 dhc at the "hillclimb" finish. No injuries but a sad TR and a definite advert for the NECESSITY of roll bars in open cars. I think the accident could have had a very different outcome without the rollover protection.

Megasquirt is so nearly ready... fitted up 95% of the hardware at the weekend and now I'm just tinkering away at getting the wiring and hose details as neat and as user friendly as possible. Should be ready very soon....

Now trying to get another diff too and mine needs to come out for a post mortem

White PI up and running + Greek visitor

Pictured just before I slapped the rocker cover back on and fired it up. Ran it for 10 minutes at 2000rpm with a litre too much oil in the sump + cam lube so hopefully no issues with cam wear on start up. I know that there are many differing opinions on cam run in but this works for me.

Just been to put some fuel in and it drives nicely. Bit flat at 2500revs, off cam feel but then very smooth and torquey from 2800 onwards and just using a whisper of throttle we're up to about 5300revs in every gear without even trying so that 100mph ooopps... its nice and strong then.

Just need to change the oil (Castrol RS 10W60) , filter, retorque the head and change a couple of injector hoses that I still haven't got round to doing.

Brakes feel fine (DS2500 pads) and I'm really looking forward to the Collie Sprint.

Might have a guest driver if I can wangle the paperwork as a certain Mr Greeks and co are on his way down to South West WA. He has already accepted a yellow Stag as courtesy car for a week or so.

Fun fun

Rush jobs for the TSOA National November 1

I guess I've been relatively lucky just needing to change cams and upgrade discs and pads on my white PI. This is Ron Marians TR6 engine. It ran a cam journal at the Wanneroo TSOA sprint but upon stripping the cause of the journal failure was the adjacent lobe failing which literally filled the oilways with swarf causing the cam to partially seize in the block (no bearings) and then get into the mains and big ends... yikes. I helped out my selling Ron a original TR5 cam that I had picked off ebay for 50 quid a few years back.. it was in perfect original nick but didn't have the 2-rings identification although the TR5 Part no. was scribed into a flat as per early PI cams. Hence the reason it went cheap...

The motor is now running and feels strong (these photos are a few days old) after a crank grind, cam bearings line bored and spitty bearings inserted + new rings and a hone.

This is Martin Eyers TR8 which is in the process of being reshelled after a major incident on the Targa West event where Martin hit a concrete wall and comprehensively reshaped his bodywork. I helped source a new shell which has had to be completely repainted and now is being trimmed. One of the complications with this car is it is fitted with a Discovery 2 4.0litre EFI V8 so imagine the one off wiring loom which needs to be re-installed!!!

Needs to be ready in 6 days time.....

Manifold Finished... almost ready for installation of megasquirt

Fuel rail secured by 5/16UNC threaded bar and locknuts

Just waiting on a few wiring loom connectors to finish off the loom (adapted from a six pot Ford falcon) and to connect the Megasquirt loom to the TPS.

Discovery Throttle cable arrived today and although a bit long it will fit fine and adapt easily once the bulkhead hole is enlarged to Rover proportions.

Fuel hose pretty much done, just waiting on an ebay 300kpa /43psi regulator ex-Ford XR6 to complete the plumbing in the engine bay.

Once the ordered Bosch connectors arrive it will be time to swap the TBI to MPFI !! Beena bit of a drawn out process.. what with work, 3 kids, rebuilding the white Pi and having to use the 2500 everyday.

Guess the Stag should be readied for summer now the 30+ deg days are beckoning as it does have the best aircon.... give me a chance to set up the megasquirt over a few days

EFI Manifold progress

Definitely getting there now. Fuel rail is drilled for injectors and fuel fittings. Just need to get a final 5/16 unc tap to allow fuel rail to be attached using the old injector mounting points and a reducer for a vacuum take off for the Megasquirt MAP sensor.

I am going to try the vacuum sensor takeoff point utilising as the the old idle air tube off the plenum log. If it doesn't give a stable reading I shall try elsewhere.

Brass 3/8 fitting is for servo vacuum take off. Engine crankcase breather will feed into the Throttle body as per Rover and idle air valve will feed into 1/2" tube where old idle screw was situated.

EDIS 6 success... by Heath Robinson

Just to check the coil pack wiring and EDIS module and VR sensor will work before rehashing the injection side, I jerry rigged the set up with the Dizzy module still attached (for the current ECU injector signal).

Fired up first time and same experience as everyone else... SMOOTH as silk even on only 10 BTDC limp home setting.... definitely reccomended. Just need to rig up a dizzy pedastal with a core plug to blank it off and a coil pack mounting and its all done

More (slow) EFI progress

Finished my plenum / throttle body yesterday. Got a flange laser cut for the Range Rover throttle body. Welded on with 4 captive 1/4 unf studs. Fabricated a throttle cable bracket for a Discovery cable. Cleaned it up and painted crackle black for the factory look.

Just waiting on a fuel rail and a bit of plumbing now.....

BTW I have several spare flanges (minimum order from the laser people) in both 74mm (Land Rover) and 64mm sizes with Ford Type PCD. Contact me if your interested... much cheapness!!

The Oz Ford Falcon TB pictured above are very common (read virtually free) but have a problematic throttle cable action (pull from the wrong side) which I'm sure could be overcome. Anyhow I got 4 flanges made for the Ford TB just in case....

Wanneroo Sprint Piccies

New Bits for White PI Part 2 Cam change

Old Wade cam out through the nose cone. Essential mod for modded Mk1's !!!! Cam was definitely on the way out. Exhaust 1 lobe about 0.220" whereas standard for this cam is 0.265". All the otheres were between 0.248" and 0.255" and showing signs of distress especially on the lowering flank.

New cam with polished journals, nicely scrolled on these early TR5 cams.

Not sure if this is really necessary on a tuftrided cam but it won't do any harm either

Installing the Cam and timing up with Inlet lobe 1 at max lift with engine at 108 deg ATDC.




Been cleaning up a spare old PI head 218225 (32mm exhaust valves) for possible modification with GT's valves if it passes the crack tests.

This will have to wait 'til Thursday as I'm off to the gold mine, then I'll cart the heads to Luigi's Head Shop for the next plan of attack. Right now I have six hours before I have to wake up for the flight.. yikes...

New Bits for White PI Part 1 .. Strip down

Reground TR5 cam using hybrid inlet / exhaust cam profile. Inlet is longer duration than exhaust and seems to give big torque and bhp. Tuftrided.

Excellent cheap alternative to most Triumph tuning junk. XJ40 valve springs. Cost peanuts and very adequate for Triumph cams and valves

New GT inlet and exhaust performance valves. Nitrided steel and stellite tips and exhaust valve seats

I have decided to freshen up the top end of my White Mk1 PI as it seems a bit down on top end power compared to Humph's freshly built PI.

Head off for the first time in seven years

I have got a new hybrid camshaft very similar to my mate Humph to try + some new Gareth Thomas valves to build into different head and a set of hybrid Goodparts Roller Rockers of 1.65 Inlet and 1.55 exhaust compared to my current 1.65:1 ratio set.

Flowed head running 10.75:1 CR and Chris Witor Big valves ... probably keep this complete but probably wont be using it on The White thing again

I will also be using the recently discovered mod of Jag XJ40 springs which look very good quality - are not too hard on cam lobes and cost the princely some of about 80p each from Jag Genuine Parts!!!

Buggered cam folowers... guess the cam (Wade 444C) will be a bit secondhand too judging be the look of these.

Stripping down the head from the Pi for the first time in about 7 years was a fairly easy process. Got it all off in about an hour. First suprise was that the rather crap Racetoration stainless head nuts were almost finger tight, certainly no more than 45lb ft so they will be consigned to the bin. Obviously have lost their torque and Stanparts finest will be going back on... what was I thinking back in 2002!!!!

The head slipped off easily revealing a mint set of bores... nice suprise considering the revs and abuse this engine gets. No scoring or ridges at all and honing cross hatch still easily visible.

Considering the lack of torque on the head the gasket looked perfect with no sign of any overheating or blowing. Not suprising really as it it was running really well apart from missing a second from it's ultimate lap time.

Whipped out the cam followers and the first sign of wear. 4 or 5 showed serious signs of surface hardening picking up so I expect the cam to be fairly secondhand once I get it out tommorrow.

Looks like the new cam might have more effect that I had hoped for .... EXCELLENT......

TSOA Wanneroo Sprint

Fun day with beautiful weather.

Humph was using his freshly re-cammed 2.5 and I was testing my new brakes. We both ended up with good results and both have things to improve

http://www.natsoft.com.au/cgi-bin/results.cgi?29/08/2009.BARB.P1

http://www.natsoft.com.au/cgi-bin/results.cgi?29/08/2009.BARB.Q1

We both got PB's on the short circuit and Humph just pipped with his new found bhp on the long circuit... time I fitted the same cam plus a few more head mods I think as my Pi is a little off the boil bhp wise after 7 years hard use.

There were a few casualties including the 2.5PI saloon of Paul Dodds dropping a rod which was a shame as it has been improving fast.

Good fun to be competing with the Westfields and PRB Clubmans (Caterham copies) and an supercharged Exige (which was obviously driven pretty conservatively!)

My brakes weren't quite right so a change of disc diameter and pad material beckons + some cooling ducts. I will be trying 296mm DBA Skyline discs (currently 280mm) and Ferodo Ds2500 asap

More EFI bits + trigger wheel sorted

Managed to find the time to whip the crank damper +pulleys off and fit a lathe modified front pulley with a 6.5" 36-1 Trigger wheel welded to the aircon pulley.

Had to space the compressor forward by 4mm to get the pulleys in alignment - aircon is nice when its 40+ deg but really impinges on the amount of room on the N/S of the engine. Just need to rig up a bracket to hold the VR sensor and the I can due a quick temporary rig up to get the 10deg BTDC default setting fixed up with the EDIS not connected to Megasquirt

Why is it you always spot a missing fan blade on a Saturday afternoon when you had access to 20 of the things on Friday afternoon :-(

Also got a Ford Falcon Coil pack and EDIS 6 and some wiring sorted. Luckily Oz is over-run with straight six EFI cars so a Falcon injector loom was obtained for free and will be just the job
