Talking about Mr Kindness car last night and was wondering about the gearbox. Does he have an F16/F18 or F20 box? Just that his speedo shows 130mph and the rev counters at 7000rpm. 130mph on a F20 shows about 6250-6500rpm though.
Anyone shed any light?

f18???
f16 and f20 have same ratios as far as im aware so it doesnt matter what box is in there
sure hes got an f20 though.
why havent you read off speed from rpm rather than speedos before your asking??? some forumalas will do this for ya nicely

F16 n F20 must have different ratios. They are different gearboxes. F16 is a closer ratio box.

F16 has different ratio and its better for 0-60 times coz of the gearing.
I think he has F20 in his

Just remember a pic of his speedo @ 7000rpm showing 130mph. Yet someone elses 2.0litre i know shows 135mph @ about 6500rpm which i'd say is more right.
F16 im still sure has different ratios as Stuyw as said.

16"
I also have 16"s though and they are fairly accurate (ish). On 15"s my car hit the limiter in 4th @ 102mph. This shows as 98mph with my 16"s. But above 100mph i dunno what happens. It sometimes (v rarly) gets to 115-120, but usually sticks around 110 flat out.

They would not effect how many revs you needed to go 130mph.

air con is free wheeling isnt it? so wouldnt sap any power until activated and also as said would not affect revs against speed at all.
