Quote "I briefly ran a PI cam on my US-spec 1971 car, using dual Stromberg Carbs, and it ran very well" I am trying to find out if you only put a new cam in the motor and leave the head and crabs as they are power output can be achieved.
-
Does anybody know what is the maximum power output for an early TR6 Carb car. Assuming the head will be kept but SUs and a TR5 cam are used.

Buyer beware. The European Breakdown Directory is at least 15 years out of date. One entrant left the country over 15 years ago. When does somebody start to update it?

Just seen this topic. I have noticed my heater knob hits the end stop before the valve is completely open or closed. Is it the bowden cable our the heater valve or a combination of both? Or even worse me.
-
Here it is not so bad.

It's the same old story. My father used to ask me as a kid "Have you ever seen a poor Bookmaker?"
Mike, if you are stupid enough to pay the money, they are stupid enough to take it.

Luckily I have Advocats insurance.

If I need to go to court, I will have to have something in writing.

I think we are all saying roughly the same thing. Except for the glove compartment book where is it written down?
-
I do not believe the garage had even done this test. I think they just put the stripped down engine, back together again and then put it in the car and gave the car back to me. Only after having tried to run it in, I found multiple problems. (They insisted that I should not drive faster than 2000 rpm for 666 miles.???????).
These problems could be put down to bad workmanship or damage caused by a Rolling road test too early. I believe the former. I did not request a RR. They gave me official papers stating there was an increase in power output.
I am not sure about the legal aspects, I will leave them to my solicitor.

I have had my engine rebuilt. The garage said it has ???? PS they have done a rolling road check. I do not believe them the peformance does not reflect this statement. . They wiil not show or give me any charts or paper to prove this statement. My question is what is the normal procedure in checking out the engine after a rebuild? Is there a requirement for the engine to be run in before putting it on a rolling road. Must the garage check the compression? Must the head be tightened down before? Is there a rev restriction? When can one put a full load on the engine for testing pruposes etc etc? I cannot find anything written down. What is the procedure. My gut feeling says:- Run it in with low load and varying revs. Tighten head down. Slowly increase the loading until you reach full load then do a rolling road check. Not before.

That's interesting. It seems that it was a Californian club. Perhaps very local. The badge on my car is from 1971 and the newpaper from 1975 which means the club was going for some time. It is strange that nobody nows anything about this club.

I have never found out who was the American owner. As the car was imported to Germany the persons that imported it threw the number plates papers etc away. Plus all the trimmings. God knows why. The trimmings costed a bomb to get them replaced.
The American owner had kept it according to American standards in good conditon. For us, it was a bucket case.
e.g It had had a paint shop job done. Quality OK but the coloured paint was all over the wiring it took about 2 weeks with Carbontet. to make out the colour coding. The front right hand side under the headlamp had had a bash. (fire Hydrant???) They had drilled holes in the metal put on a lot filler, of which enough got squashed through the holes to hold this amount of weight in place. Instead of an axle mounting stud a piece of scaffolding and a long bolt were inplace. On the other side the spark cables were all numbered. The Emmision system was perfect. So what should one say?
-
At least I am happy to see this is a badge from a club that is no longer known. I have been trying to find out what it is since the International in Stafford. Years ago.
-
My O/D dropped in and out on the motorway. I found the relay metal cover had come loose and after every bump it was shorting out the O/D. I found a rubber band, and this held it in place for the next 6 hours.

No I did not know there was a Canadian correspondent.
RKG I have had a very rough look but it seems unlikely if it will help.
It must be known somewhere in California as it was on this American car. Inside the door panel was a visiting card from a Mr Wong's garage San Fransico, California. I checked with google it does not exist anymore it is now a testing station
-
Thanks I wonder what will happen?
-
Can anyone provide information on this badge. It has been on the glove compartment door since day one. I have had no luck in America. No luck in the TR6 forum. So I am now trying on a broader basis.
-
OK so it is a 5 and not a 6. It looks to me to be another type of punches. Thin and not straight and upside down. I wonder if anybody has the same? If so then it might be a factory job.
-
Maybe if yes then it is very poor workmanship.
-
It is strangely stamped upside down and very unprofessional. It is so bad/weak that I have not managed to make a photo. It needs a flash and as a result it mirrors. A gut feeling says that the old number, for many years has been removed and replaced with this funny number.
-
Thanks

I ran my PI for years with a CO value from about 2.8%. Performance was there. Consumption was there. After many years I took the head off and everything was ok inspite of using Unleaded. Wherby the butterflies etc were in top conditon.

I have 2 TR6 cylinder heads I know about the casting numbers but I cannot match the stamped number to a TR engine any help please. I am sure this question has been asked many, many times.
The stamped numbers are Head 1. 516323 which I pretty sure is an early US 6 or 250
Head 2. Is baffling me 616323 it may also be a early US 6 or a 250
Possible power increase

Sorry have been off line for a rew days. The question was what power output can one expect, if any, with just a cam change. On my 6 I have had a TR5 head. TR5 cam, spitfire exhaust and double HS6 SUs. It goes like a bomb. I had (with the hood down) on the German motorway 120 mph on the clock.whatever that means. It was Covid time and the roads were empty. I tried it out as I had just managed to get a new set of high speed tyres. Now it is back to chuff, chuff, chuff, but for overtaking in the country it is great.
