Hi John,
Can I assume http://www.amazon.co.uk/Braille-Battery-B14115-Advanced-Lightweight/dp/B004DDI1AG/ref=sr_1_1?ie=UTF8&qid=1366120148&sr=8-1&keywords=braille+Battery#productDetails or http://www.amazon.co.uk/Braille-Battery-B2317-Advanced-Lightweight/dp/B004DDNHO6/ref=sr_1_9?ie=UTF8&qid=1366120148&sr=8-9&keywords=braille+Battery for instance then would not be suitable? I need to check my existing battery but think it could be circa 16kg, so perhaps there is scope to fit a smaller one given I run a high torque starter.
The car does not have any drains i.e. when switched off aside from a Kenlowe fan perhaps, therefore with a denso alternator i'd of thought it would cope?
Triumph-V8 - thanks, it is a 2.5 I don't know the precise spec but think its: balanced, 40 thou hepolites, race 6-3-1, weber 40s, good compression. Perhaps with a new cam there would be even more! Having been in a few other cars and know of some other tuned triumphs that have used the same rollers, the seat of the pants performance backs up the graph fyi.
Cheers
