G50 Gearbox Ratios
Discussion
The G50 comes in a number of ratio configurations.
Does anyone know the MPH per 1000 RPM in top for each of the boxes using the factory GTR wheel and tyre combo.
Also can I do a mini survey to find what the normal Max RPM is for our road legal and road mannered Chevy engines.
As I am building my own engine I have the opportunity to spec the cam to produce torque and HP where I want them in the rev range.
Many thanks
Steve

My final gear has 30.29mph per 1000 in top gear, not really relevant for you as it has a modified diff that I don't thinks available for the G50's (it's 4:1)
There are so many variants of the box that you really need a lookup table, I think BIGMAC had one of these and forwarded it to CJ (STIG) best bet would be to get a copy of that.
You can buy aftermarket gears and they are around £600 each gear I am told.
I personelly prefer revy engines and mine was dyno'd to 7100rpm but I have set the limiter at 7000rpm, I had to specify a different cam (solid lifters) etc to get the extra revs and suffer from marginally more engine noise as a result.
However whilst I have used it on track and road I have yet to hit the limiter due to the huge power band. It's almost like a reserve above 6500rpm if I need it.
