The Triumph Dolomite Club - Discussion Forum

i'm guessing they don't show any dolomite ones because they won't have made many. i saw a Tony Law example on Ken Osbourne's black racecar sprint earlier this year.

and I only mentioned JP as he has made Vauxhall XE manifolds recently so am considering him to make mine!

I too have seen that car, artwork.

sadly in the race he had a similiar issue to what we have recently been discussing, trailing arm/axle failure! (i don't know which exactly. me/my dad have been meaning to call him)

ended up with retirement as there wasn't much rear tyre left.....

Tony Law exhuasts are not a straight forward fit.
The car needs to go to them to have the System fitted.
You will also require the Turret to be cut out in order for the system to clear, these systems are for track / race cars unless you want to go chopping out chunks out of your nice road car

quite correct!

the lack of clearance on a sprint engine is ridiculous!

Yep, esp when you look at a TR7, in it falls!

Yet another reason to not use a Sprint engine if you want a properly quick Sprint! (Dives for cover!!!!)

I need about 3 pairs of hands to count all of the reasons on

A number of years ago when I was racing my Sprint I bought a F3 motor from Holbay. It had the oil filter housing machined off the block as it was dry sumped and had a remote filter. This allowed me to fit a small Japanese starter motor where the housing had been. Doing this meant I could remove the massive Lucas starter which gave me a lot more room to build and fit a tubular exhaust header. It would also be possible to stand the motor up a little giving a bit more clearance. The works engines still managed in excess of 210 hp with the cast manifold so it cant be that bad.

Found a couple of pictures of what I am talking about

Happy xmas all !

Found this place which makes tubular exhaust manifolds for £428 ... Retro-engineering.co.uk

Cheers, Richard

No point in doing a tube header for a sprint
Unless your going well over 7k and want 220 hp +
A standard manifold well fettled will be ok for 99% of what people
Want out of a road and track day car
You would gain more just removing some weight from the car,

i thought i recognised that website...

seems like they don't have a great reputation (going on what happened to this french gentleman)

Is there any advice out there on how best to port the cast iron Sprint manifold? Aside from matching the ports,there's not much material to grind away - or at least I can't see where you'd try.
