Hi DBLDrew

and thanks for your comments this is exactly the type of discussion I hoped to promote. As I previously said the ZFQ can be supplied with different gear sets and final drive ratios, below is the table with a final drive of 3.77 giving a cruising speed of 87mph at 3000 rpm and 189 mph top speed at 6500.

In reality I acknowledge that the GT40 is a 200MPH car but it runs into an aerodynamic brick wall at around 165mph even Roy Smart with 500 Bhp on one of the longest airstrips in the UK had trouble going 170 Mph +. A professional driver driving an original GT40 at this years Le mans classic said that now the Mulsan straight had checains installed that his decision to run the 3.7 final drive was the wrong one! and that next time he would run the 4.2.

I doubt that there are many people on this forum that would ever get the opportunity to exceed 170 Mph.

The choice of which final drive and gear set is still up for discussion and I welcome further comments on this as we need to come to a decision in the next seven days on this for the first 25 transaxles to be manufactured.

regards

Chris.
