Hi everyone,
just after a bit of advice regarding which final drive ratio to chose for my set up. I have searched to check topics for answers, but they are usually for 4 speed gearboxes, where as mine is a 5 speed.
My full spec is -
1330 mpi block
Specialist Components supersports head
SW5 cam
Specialist Components stainless exhaust
Specialist Components typhoon ECU
1.5 roller rockers
Minispares helical 5 speed close ratio gearbox X-pin diff
The conundrum is do I go for 3.6 FD ratio, as I have 5th gear as an overdrive, so will be equivalent to just under 3.2 in 5th.
The worry is I will be lighting the tyres up everytime I pull off with some welly, plus will I run out of legs quickly with a 3.6 close ratio. Plus equivalent 3.2 FD ratio - engine still revving quite high at 60mph?
Or do I go for 3.44 for more all round use? (in 5th that gives about 3.0 FD)
Also, the SW5 cam should be pulling well from quite low down, so won't need a 3.6?
It isn't a track car and won't be used every day, just for weekend country roads blasts, though do want to be able to cruise without the engine screaming (yes, even in 5th!)
Any advice/experience gladly recieved!!
Neil
