What is WRONG with this TR7 V8 Help please?

[bonnietiler]

I realise that I must have bought a pup, I paid alot for this car and although it is in slightly tuned Std Stromberg trim (140 bhp at the back wheels) It's proving a difficult conumdrum to positively identify but I'll try to be concise.
When I bought the TR7/8 (last September)I also had my runabout a mint condition 1 owner 40k Rover 45 1.8 auto, I paid £950 for it I changed the cyl head gasket and it has always been faultless. Sadly the Rover in is stunning Metallic Royal Blue sheen had attracted that lowest form of miserable underclass, the very nadir of the concientious motorist,
My Daughter-in-law!
Oooh how she wooed me with those cow eyes and lashes all a fluttering.."Bbbbbut my ppppoxy Peugeot is all but dead in the water and you wouldn't want little Ash n Evie (grand-daughters) being put in any danger by being transported in an unsafe car would you" Luckily, I am made of Stout Saxon Stuff...ohh yes indeed...I don't so much as quiver in the face of emotional blackmail such as this.
So, seeing as I'm down to one car now, i have been using it every day as a commuter and up and down to the Lake District every other weekend, I realise that I must have a serious problem with the car, It returns 21 mpg around town and 33mpg on the M6, so you see my problem..also it starts on the button (key) no matter what the weather and lives outside uncovered..clearly that's not right..Everything electrical works and the brakes after an MGRV8 brake pad transplant are superb..So what the heck is the matter with this car, It isn't behaving at all like the Tr7/V8's that I read about over the internet?

33 mpg in your V8 hhmmmm.....
I think your not putting your foot down hard enough you should be getting at least 10 mpg if driven properly [:D]

I have to admit that in order to get that figure my foot quivers fearfully over the throttle like a tremulous finger on a hair trigger, but with the 3.08:1 axle and in 5th (always) not to mention a parsimonious love for the combination of the atomic deadlock on my wallet clasp...it can be done.[:)]

You definitely need to give it more pedal to the metal stuff!

My second TR8 was an absolute mess when I bought it! It was originally gold, repainted to BRG, and the wiring was a complete and utter mess. Once I sorted out all the problems (mostly previous owner related...) I never had any problems or breakdowns in the years I drove it (well, except for one flat tire on a drive) [8D]

My v8 conversion has also been reliable, in the last 2 years I have done nothing except service it, averages around 24 mpg on lpg so is cheaper to run than many modern diesels.

Mind you I do now need to get a bumper end cap as I smashed it off over xmas. And it will need a couple of tyres this year, hardly the end of the world though.

Given they have a powertrain developed for a much larger car, if the conversion is done properly and they are serviced properly they should be reliable really. I suspect many peoples problems come from lack of use. Years ago I gave up laying my classics up over the winter, I have had far fewer problems since.

bonnietiler, I think you should burn that car quick time. It is giving Triumphs a bad name.

You need to go out and drive it like you stole it......... before someone else steals it and drives it accordingly! [:D]

Regarding your electrical problem,you obviously have not bought any Lucas wiring harness smoke.
Once you have some of that your car will be back to normal.

I may be tempting fate but compared to moderns full of fancy electrics (ignoring the headlight lift mechanisms), a carb'd TR7V8 is a relatively simple beast.

A 7's electrics, especially the connectors and switches in my experience can be fragile. It sounds like the PO kept them clean.

Enjoy it while it continues..........and tell the forum if it does or doesn't, we can all help and learn from it.

I dream of experiencing your mpg, your rear tyres will probably last too long at that rate.[:D]
