CageyH Posted August 23, 2010 Share Posted August 23, 2010 Alex, try BGH or SPC. I have the SPC semi helical box with the long 1st and it works well. Only dead fish go with the flow....! Link to comment Share on other sites More sharing options...

Eugene Posted August 23, 2010 Share Posted August 23, 2010 I've used BGH a number of times - very good company... Small Boy - with Loud Toy! Co-founder of the BOG Club See Eugene here and see what I do here Link to comment Share on other sites More sharing options...
Racing Snake Posted August 24, 2010 Share Posted August 24, 2010 BGH here great service and great gear box Mad Hatter Racing - Feel The Duralight R Torque 😬 Carl @ Penn 7's Caution - May Contain Nuts ! Link to comment Share on other sites More sharing options...
Leadership Team Mcalvert Posted August 24, 2010 Leadership Team Share Posted August 24, 2010 Another recommendation for BGH here. They very successfully rebuilt, and modified the ratios in my 5 speed box a few years ago. Their website and price list can be found here. All the best - Michael.

CageyH Posted August 25, 2010 Share Posted August 25, 2010 You will need the heavy duty box at the very leat in an HPC. Only dead fish go with the flow....! Link to comment Share on other sites More sharing options...

Leadership Team Mcalvert Posted August 25, 2010 Leadership Team Share Posted August 25, 2010 Do a Google search for a free application called Gearcalc. It#ll allow you to model the effect of different gears on your particular car's combination of diff, wheel size etc! Also, Ask for advice from BGH - they have a lot of experience of this conversion for 7s. Regards - Michael. Link to comment Share on other sites More sharing options...
Jon Stewart Posted August 25, 2010 Share Posted August 25, 2010 I have the SPC heavy duty semi-helical in my VX and like it. Ideal ratios for the road although a bit long for track use with a 3.92 and high revs. I see SPC have "1 x Unused Quaife T9 5 speed semi helical gearbox,long imput shaft,2.39 1st,suitable for Caterham seven etc. £1100.00+vat" here Link to comment Share on other sites More sharing options...
