TT-01 Gearing FDR's - for Faster motors

[Perko]

I wonder if someone can clarify this for me please? Just about to get a new TT-01. I thought I had gearing sussed, until I read two posts which say similar things but seem to contradict each other in terms of high /low FDR's for stock and faster motors.

The one from the first post on the "TT-01 essential upgrades" pinned topic says:

"In general, when you fit a faster motor, you fit a lower FDR. Fit a slower motor and you need a higher FDR. That doesn't take into account the space you've got to run the car in, so smaller areas mean a lower FDR as you're not going to be able to reach the top speed with a high FDR, so its always a balance of top speed and acceleration that match the motor and the area."

However, the one from the pinned topic on "Confused about gearing" (again 1st post) says:

"In general, when you fit a faster motor, you fit a higher FDR. Fit a slower motor and you need a low FDR. That doesn't take into account the space you've got to run the car in, so smaller areas mean a lower FDR as you're not going to be able to reach the top speed with a high FDR, so its always a balance of top speed and acceleration that match the motor and the area. For touring cars at least, FDR's of 7.5 or above are considered high."

I'm getting a 17 turn modified motor, so would really appreciate if someone could clarify whether it's best to go for low or high FDR's for the best speed please?

Cheers, and thanks.

Its the second one, fast motors need high FDR's.

Thanks Garry!
