ZFQ new proposed GT40 transaxle

Hi Guys

We require your constructive opinions on a brand new proposed GT40 transaxle to be known as the ZFQ. The new transaxle is dimensionally the same as a ZF and will be able to be directly bolted in place of a ZF unit in a GT40. It will bolt to the GT40 ZF bellhousing and have CV output shafts as standard in exactly the same dimensional position as the ZF. The transaxle will be fitted with a Quaife ATB differential and will be rated at 550 Ft lbs of torque with a maximum of 600BHP. at 7500 RPM.

This new 5 speed full synchromesh transaxle will have a H pattern gate and will have both solid and cable shift options.


The proposed gearing is shown in the chart below but however custom gear sets and final drive ratios will be made available.




Differential: 4.22
Tire Diam: 26.9 PERCENT DROP FROM
1st Gear: 2.30 DROP 6500 RPM
2nd Gear: 1.54 0.670 4352.2
3rd Gear: 1.14 0.740 4811.7
