triumph TR6

hey all, i just picked up 2 TR6's for a song and would like to know if anyone has any experiance with themn or knowledge on extracting more power via forced induction.
thanks
71' and 75' are the two yrs.

 

Er, the only value in these sort of cars in in originality ... plus the motors are close to a waste of time for working, or atleast a huge money pit.

For a start you would have to get just about every machined surface remachined because Triumphs concept of accuracy was plus or minus 1mm ... which is a real pity because if say Triumphs had been built by Rover they would have taken on BMW!, but instead they demonstrated how lackluster the British lazy worker really is.

Anyway, yep you can buy race cranks for these (a definite requirement, as the genuine is just cast iron and very heavy, and will need massive balancing work anyway ...) and weber carb manifolds, you will need to replace the piece of **** gearbox with one that you can change gear in without notching yourself up in a knot. You will also need to replace the clutch mechanisim with something that lasts more than a weak ... and does not wear itself out constantly adding weight to the clutch effort.

My father used to be a Triumph specialist and I have a soft spot for Triumphs but adding power to a motor that is struggling against very wide manufacturing tolerances, driving through a gearbox that is close to one of the worst ever produced and then finally feeding all that power to a rear suspension that already struggles with worn splines ... er, just does not sound like a good idea.

Restore them instead and build everything how Triumph SHOULD have and you will end up with nice cruisers and great fun cars!

Pete's opinion
ps: Sorry for my blunt response ... not what you want to hear, but it just pisses me off that a company like Triumph that had such promise was destroyed by their cost cutting method of implementation and lazy bloody workers.

I have driven Triumph saloons that my father rebuilt and balanced the engines of and they are a different and amazing cars ... so smooth and refined ... and how they SHOULD have been built!

 

i was contimplating a SBF swap, but it requires some modification. minor sheet cutting and a new drive line. sounds like it might make more sense. i bought them both for less than 25% of thier current value. so i'm not out any real money but didn't want to ruin any future gains. the TR6's in the states are moving up in value.

 

You could always do a LS1 swap:

Er, what is SBF?

I remember as a young man (around 15 or 16) repairing a clutch on a TR6 and rebuilding the linkage. Clutch actuation was much lighter . One of the most memoriable road tests I ever conducted with the roof down ... I was gone so long that my father was pacing up and down his business driveway when I got back with a very relieved look on his face ... oops, guess he thought I had stacked it!!

I had a cherry GT6, it was my second car, had the TR6 motor, I don't think you could get away with forced induction, these motors are closer to the tractor engines in design which they were taken from to make the TR3 which my Dad bought new in the early 60s.

I think you could dump the strongbergs put in some Webers and cams it will give you more power, the IRS with the lever shocks is fairly weak design clanging and banging on rough roads I think you would need to mod that up to handle the extra power, the TR6s are fun cars and sound cool and are the best looking of them next to the TR3.

 

We broke a rocker arm on our TR over the summer.

 

would you really care how hard one of these cars went? i'd spend my cash on making it pretty and get the mechanicals good enough for leisurely cruising.

that said, my old man rebuilt a spitfire when he was my age, but said he went way overboard on it. said it revved to about 13,000rpm, but wouldn't be capable of moving under 6,000rpm. back in the day we had GTHO falcons as the premier tarmac eaters, and his little spitfire could outrun them to 100mph but then the falcon's would get away. so the story goes...

as an aside, i just went to a triumph show this weekend gone, got some piccies.
