New Pace 427 Build

[Tonus72]

Hi Richard

that is great info and detail - thanks for the pic too. Thanks for the heads up on ABS - it is not something I plan at this stage, but I am open to it. It all comes down to how much more complicated it is. By the time I can start my build it might be an ADR requirement anyway.

Sambo - I have not got down to that level of detail yet. I see what you are saying though about the extra overdrive. I will wait and see what others find is a good combo taking the various diff ratios into account too. I would be happy with about 2000 revs or just over at 110km/hr in top. With an LS3, TKO and 3.27 diff (from memory the highest HSV non-LSD diff) how would that work out?

Cheers

Tony

Here's a handy tool.

MFactory® Competition Products - Gear Calculator

Just plug in your tyre size (eg, 275/45 R17), 3.27 final drive, redline for LS3 is 6600 and ratios for one of the LS boxes in the link below. Drag your mouse over the graph to find RPM for a given speed and gear.

Gear ratios - Magnum 6-Speed Transmission

When you click calculate it uses the "query string" in the URL to store your settings - which you can then bookmark for later. Here's one example showing 1500rpm in 6th gear for the "TUET11009" variant.

97km/h at the top of 1st gear and a top speed of 408km/h, nice!
