Title: What gear ratios? Post by: gyles on June 01, 2010, 19:54:14 pm Seeing as how I have just bust my gearbox on the strip, now is an opportunity to put together something a bit more bespoke.
Just an open question as to what ratios and internals any loungers have experience with that work well in their own boxes. I am running a 200hp motor with nearly as much torque and want something I can take for a run on the street in the evening and then spank on the track at the weekend. Thoughts and suggestions please.

Rear tire size is an important factor to consider. But remember that your 4 speed ratios are always a compromise between street drivabilty and track use. Title: Re: What gear ratios?

I had a word with Peter over the weekend, gonna ring him sometime once I get brave enough to drain the gritty syrup from my box and see what damage is done :'( Just thought I would ask around and see what experience people have themselves.
Boom Boom; I thought real men didn't use hairdryers :P Title: Re: What gear ratios? Post by: Martin Greaves on June 02, 2010, 08:01:40 am No real men runs with drums. :D
Title: Re: What gear ratios? Post by: H67bug on June 02, 2010, 08:07:26 am If you can- 5 speed with .89 5th on 3,88 r and p
I run a short short 4th at the moment to save the 5 speed on the track but it does mean I drive less now- before 1000 to Cornwall and back was fine but too short a 4th and it borders pushes the limits of "street car" really.

3.78, 2.31, 1.65, 1.31, .89 3.88 R&P ;D Just ran a 12.7 on Sunday now retired the car to enjoy on the street. Title: Re: What gear ratios?
