David P Posted June 27, 2016 Share Posted June 27, 2016 It's the torque you need to talk about and cap at 700, the bhp figure could be more. Quote Link to comment Share on other sites More sharing options...
Style Posted June 28, 2016 Share Posted June 28, 2016 Any idea on VVti numbers David? I'm not sure if it's just a case of adding 0.5 to the non-VVti CR figures or not. TT pistons and TT HG on VVti head might be a nice combo Quote Link to comment Share on other sites More sharing options...
David P Posted June 28, 2016 Share Posted June 28, 2016 I don't know if that 0.5 is due to VVTI pistons or head? Quote Link to comment Share on other sites More sharing options...
Style Posted June 28, 2016 Share Posted June 28, 2016 I don't know if that 0.5 is due to VVTI pistons or head? Volume of head is different. non-VVTi 10:1 compression head = ~76cc VVTi 10.5:1 compression head volume = ~72cc Quote Link to comment Share on other sites More sharing options...

David P Posted June 28, 2016 Share Posted June 28, 2016 I seem to remember that they have smaller skirts and are lighter for higher revs, yet have never seen info on crown specs? Quote Link to comment Share on other sites More sharing options...
Style Posted June 28, 2016 Share Posted June 28, 2016 There's a little info on that here but no figures unfortunately http://my.is/forums/f88/2jzge-vvti-piston-crown-pictures-178937/ Seems to be that they yield the same CR but are slightly different in design Quote Link to comment Share on other sites More sharing options...
David P Posted June 28, 2016 Share Posted June 28, 2016 It's unfortunate the promise of a test fit came to nothing, the smaller valve indents are untested for clearance. Quote Link to comment Share on other sites More sharing options...
