Dogbox dilemma

As the title states, I'm toying with the idea of upgrading to a dogbox for hillclimb and sprint use (the car is also occasionally used on the road). I was hoping someone could let me know just how significant the gains of upgraded from a 5 speed to a dogbox are?

I imagine using a dogbox would give me better gear ratio's and hence would allow me to utilise my power band more effectively, but to what extent? And just how much stronger are they from the standard 5 speed boxes in the 6 gsr's.

Cheers,
Julian

Hi m8!

As well as optimised gear ratios, you can also use sequential shift with flat shift, which knocks 0.x seconds off with every upshift

They are a PITA on the road and do need pretty frequent rebuilds, though...

My car was offered for sale with one, but since I use my car on the road mostly, I chose the RS Medium 5-sp instead...

Cheers

Rog

Hi m8!

With a dogbox you can specify whatever ratios you want

The medium RS box is geared for 140mph at 7000rpm in 5th, compared to the short RS box at about 125mph at 7000rpm in 5th, so it depends on your circuit which would be better

Put a post up on here if you're looking for one, or contact the likes of Wayne at Arnside: http://www.stationgaragearnside.co.uk/ He'll tell you everything you need to know about gearboxes!

Cheers

Rog

Cheers, you certainly know your RS ratios! One last question, whats the top speed of the standard gsr 5 speed box of the VI, just to get an idea of the ratio differences?

Cheers,
Julian
