Here's a graph of a 6gc with an S54 (ST202 non-superstrut and all ST204), C52 (AT200), E56 (ST202 with superstrut), E153 (swapped camry v6 or MR2 turbo tranny), and E154F (ST205) gearboxes showing the vehicle speed for various engine speeds for all 5 gears on stock wheels & tires.



>>mph>>









>>km/h>>










For those of you running aftermarket wheels & tires, you can download the .xlsx (Microsoft Excel 2007+) file from here: DOWNLOAD >>(80 KB)>>

the file's protected so to edit the spreadsheet, click on the "Review" tab in Excel, click "Unprotect Sheet" and enter the password "6gc". then you just need to input your wheel & tire sizes in the correct tab (ie. S54, C52, E56, etc.), press Enter, and the graphs will update themselves.

the estimate assumes no deflection in the tires. in other words, the tires are solid and don't conform to the road (ie. no weight on the tires). so this is an over-estimate of the actual speed as the deflection in the tires depends on the tire stiffness, sidewall profile, type of tire, vehicle weight, etc.

Nice table! But you got a little error in it.

The calculation for the tire diameter should look like this =(I4*25,4)+>>2*>>(E4*G4/100) instead of =(I4*25,4)+(E4*G4/100) smile.gif

what would be perfect is if you could show the graphs you have on each tab instead of one merged graph to eliminate all confusion
I went full retard once, too. Its OK.

Hell yes, I've got 17x7.5 wheels and 215/40/17 tires, and all my values are lower compared to the graph.

my 205 goes to about 50-60 km/h not 80km/h

Yeah, I'm pretty damn sure that when I hit 7000 RPM in 1st gear in my ST205, I'm about 4km/h faster than what you have -- 35 miles = 56.32704 kilometers


Forget about tyre size too, the speedo is pretty dead on when you have factory sized tyres , 1 size up is about 1-2% under reading, 1 size down is about 1-2% over reading

Great stuff, will add this along with others to the stickies tomorrow.

could you also add the E56, I can pm you the ratio's of you need them. and maybe also the E153?
