MFactory Gear Calculator

Hey,

How accurate is this calculator? I only ask I was thinking about getting a 4.785FD for me EK9; was just comparing them to stock on the graph and my revs seem to exactly match the 4.785FD?

My car reads :

3k 3rd = 30mph

4k 4th = 40mph

2.3k 5th = 40mph
3k 5th = 50mph
4.1k = 70mph
4.7k = 80mph

Car was RR'd when it just had a Mugen CAI and rest was stock @ 167bhp - which is about spot on I think? so don't think it's down on power. What else could it be? (i'm only scepticle as Dunk didn't mention anything when I bought it and I guess he's driven enough EK9's to know what they feel like stock or not!)

Yup, seems like you are already running the 4.785 FD in your tranny

What size tires you have?

195/50/15 - stock are 195/55 ? so am I correct in thinking this is only going to make my speedo overread slightly if anything? (or have I got my maths the wrong way round?!)

your tire size is fine, that is a very minor difference. You should be seeing 4400-4600rpm max at 80mph and thats if your gauge cluster is not that accurate which is usually the case for the non-ek9 clusters.
