Title: Guess the MPG
Post by: Dave on June 28, 2009, 22:19:00 PM
As title says guess my new average MPG figure based on 1000 miles with the latest mod to the Minker  

Got to make the most of a english summer so I have bolted on my latest development for the Minker & I am off round Wales for a bit

i drove mine from manchester to chester average speed, well twice the uk speed limit and was impressed at getting 20ish mpg.
towing a caravan i would guess average of 18ish mpg. depends where youre going with it. i towed my lunar delta with my v6 shogun down cornwall and it bankrupt me at just under 10 mpg

It will be mostly crappy roads that go up & down + the odd dodge the sheep maneuver

So you saying 18mpg then Gaz

Oh & did you get some wheels mate?

I would say, towing that mobile road block, that you would be lucky to get much better than 12 MPG. Cheers Ray

Well, i hope it runs a bit better than my 2.9 Granada MK3 did, that only did about 15 MPG (7 km/s a litre...), that was without a mobile parachute behind it to slow it down..
So i guess about 18 MPG

O.K the first guess of 18mpg gets the prize if correct  

High powered cars usally do well when towing as a guide I took a tuned 24V Granada a few years ago 2222 miles around Scotland with a caravan on the back.

It averaged 22.5 mpg & that car did 14.1 quarters, 6.1  sec 0-60's & would do the clock.

Was a great trip that, one thing I remember is beating 3 Golf GTI's upto 100 mph that where racing each other with the caravan on the back of the 24V.
It was along the shores of Loch Ness.

The disgust on the guys faces was priceless.

Been a little naughty out pulling cars trying to over take me & today we have gone across the black mountains which is single road with pull in spaces, 2nd & 3rd gear for 20 miles.
Not the best for mpg so far.
150 miles was half a tank so theres a clue?

Post by: turboshed on June 30, 2009, 18:16:38 PM
i would say 13mpg at a guess but i suspect the sierra tank gauges never show right as the tank is not square,reckon you'd be lucky to see 250 out of a tank towing a caravan.

caravans really annoy me,but if i seen a minker pulling 1 it would make me smile.

Bet theres some surprise on the faces of other drivers as they get out accelerated by a sierra pulling a caravan.... youve taken the "sleeper" concept to a whole new level dave:biggrin: btw- you online when your mobile then
Title: Guess the MPG
Post by: Dave on July 01, 2009, 17:56:20 PM
250 mate! did 270 before i filled up there's another clue but that was before a 80mile trip & the next garage would have been pushing it.
Yeah lots of confused people espically when a caravan is overtaking cars up hills.

Yeah fully mobile mate between the laptop & iphone i can get online anywhere.
This post comes from a pub in tenby after another cracking day.
Can't believe we are still in the u.k.
Weathers to good!

A little update.......

I am now heading north  

How I have managed todo over 500miles heading only west I don't know but I have. Gonna be way over 1000 miles  

Things I have noted.

Car is more than capable of over 250 miles to a tank even on the narrow mountain roads of Wales.

Car bottoms out on farm tracks with the caravan  
Needs to be higher at the back.

Had to enrich the idle fuelling by 3 turns to get it stable enough to tick over correctly so I could reverse the caravan up hills without stalling it in 30 degree heat  

1st gear & reverse is too tall for good hill starts with the caravan because of the diffs.

Gearbox soon hits 120 C when towing but don't seem to go any higher.

1bar of boost in 3rd pulling the caravan up hill overtaking causes a clutch burning smell but no noticeable slip.
Must stop doing that!

My new spec turbo's are not as good as the old ones for the road.
So another re-design soon  

& that's it at the moment.

Wales is FAB really enjoying it.

Post by: Dave on July 10, 2009, 19:56:59 PM
Nah that temp is O.K.
I use dexon 3 ATF it's o.k for alot more heat than that.

 
Had major problems sunday.

Just filled up with fuel.
Started climbing a very steep hill, boosting about 10psi in 3rd.
Caravan on the back.
Car stuttered violently then dropped down to 2000rpm where it proceeded to pull strongly but would not pull over 2 psi of boost or rev over 2000rpm.
At the next layby i stopped but basic checks revealed nothing wrong.
Carried on the 60 or so miles to the next camp site.

Car would not rev past 2000rpm no matter which gear but would pull as normal untill 2000rpm then it was like as if a limiter cut in.

I had no tools with me so tried some local garages.

6 in total with no soluction! I even told them what to test & what I was fairly sure what it was which turned out to be right.
But they either thought they knew better or didn't have the gear to do the tests.

It ended up with me buying 100 quid of tools from halfords & fixing it myself in a cattle market car park covered in crap.
Oh & it was peaing down with rain to.

It was something I should of done better 6 months ago
so only got myself to blame!

But what was it?

After driving around trying to get it fixed car was now almost undrivable.
Would kangeroo all the time, had so little power was having trouble overtaking cyclists!


Anyway after wasting a day going round them garages I have come to the conclusion that if it ain't got a OBD II socket then most garages have not got a clue what to do.
Infact some mechanics need to go back to mechanic school as they don't even appear to understand the basic workings of an engine.

Rant over!

After testing the fuel pressure with my home made tester I found 1.75 bar & that was it, never increased with boost or nothing.

No sign of leaks etc so I needed to drop the tank.

After the pump emtied 3/4 of a tank in like 5 mins I decided to rebuild the FSE regulator next as the pump seemed fine.
That checked out o.K.

Dropped the tank to find the hose from the pump to the top of the tank had split  

I replaced the pump 6 months ago, with it was this weedy looking fuel pipe that at the time I intended not to use but as I didn't have anything better at the time I ended up using.

THAT WAS A MISTAKE  

That was it, going up that drag of a hill would have ment about 6 bar of pressure at that pipe which split it.
After that I never probably had more than 2 bar of pressure which is not enough to run the engine over 2000rpm as it's comming onto boost.

Simple as that.

Fixed it & we where off again.

Gota drop the tank again however as now the gauge is way out  

Ran out of petrol racing with a Golf round Snowdon & the gauge was not even in the red. Luckly it was on a mountain which we rolled back down, once flat it restarted & we made it 8 miles to a Shell garage  

All good fun.

Really enjoyed Wales much better than you think, honest!

1 day left & it looks like we may just make 2000miles, so did a few more miles than I thought

You'll have to tell me more about the Wales experience.  I fancy a trip there but am a bit unsure about the inhabitants.

All good fun.

I reckon I'd of lost it, BIG time, havin to buy tools etc, etc. Must say, as soon as you said "2000 rpm" I knew it was fuel supply, either and blockage or a leak... what a bitch having to get the tank down in the mud and rain  - bloody good show! RAC is for GIRLS

Post by: Dave on July 12, 2009, 12:18:01 PM
Yeah comes to something when you have to do it yourself.

I didn't want to but if I had to in the end as:

A. I would have had to wait 2-3 days for a garage to do it
B. Would have cost more
& C. almost certanitly I would have to redo the work when I get home.

Not the safest way to do it as I had buckets of petrol all round me but didn't have alot of choice at the time.
Lost quarter of a tank through evaporation  

As for the garages well one had tuned up EVO's & Scoobies outside.

I told him what to test & went for a big Mac.

Came back to find the plug leads missing, a spark plug & the air filters  
They reckoned it was either the leads or the plugs & had ordered both.

I had a right argument about the basic workings of a engine with them, then they said the air filters where to small & was the problem  

With that I called them a load of names threatend one of them & as he went to call the cops I put me bits back on & drove off.

Still waiting for outcome of that
& I found out they never had a fuel pressure tester which he said he had as it was the first thing I asked.  



Anyway enough of that.


I used 7 tanks, did 1814 miles using a total of ...............


365.91 litres of fuel, which means the average MPG of the whole trip was .............





22.54 MPG rounded up to 23 MPG


Not bad really considering I never saw a motorway for 10 days, probably drove about 200miles of dual carriage way the whole trip & went up + down more hills err..... mountains actually than I ever dreamed of.

So the winner is ......................................

"23mpg  same as my explorer on a run (if you dont floor it)"



& No it is not a fix  

Just Tone knows the car so I guess he took a educated guess & got in first  

Free burger for Tone

      can't see there being any come back if you didn't actualy give anyone a dig. Confirms what i always suspected bout them ricer boys  

Anyway, 23 mpg is amazing all things concidered. well done tone, enjoy that burger

Heya Dave,

how was the holiday mate?

How did the 'mod the towbar at the last minute' towbar hold up lol? not had them heads machined yet, works got a bit iffy atm so dont know when i can sneek them in, but at least i started bolting the manual box to the scorpio though  

Title: Guess the MPG
Post by: Dave on July 25, 2009, 23:20:14 PM

My custom re-designed towbar was great mate infact thank god I changed the design slightly as it would have made dropping the tank harder than it was  

Yeah you should get a towbar too, you can have lots of fun in a caravan
