wheel sizes make fark all difference in readings

I made 440 ish with 20s (my surge pump maxed)

a mate with very similar mods made 446 or 447 ish with stock g6e wheels.

same dyno

That 6-7 is all he is looking for. Considering the 17 and 18s are the same size as 19s here is a comparison 19-20

245/35-R19 245/35-R20 Changes Deviation 80 km/h Circumference 205.49 cm 213.47 cm 7.98 cm (3.88 %) 82.99 Diameter 65.41 cm 67.95 cm 2.54 cm

If the speedo is out 2-3km at 80km/hr the final drive ratio is now different and torque multiplication will change (people change diff gears). This may effect shift points and there may be a weight difference of the wheels as well.

3.88% at 295kW is equal to 11.446kW.

Worth a try on a free mod isn't it but don't expect to get that full amount.

Car will stink with no cat. Fumes

I'm running no cats (straight pipe) on E85 an barely get any smell at all.

Cat or no cat.. were all kiddin ourselves

No after market cat will meet emissions. (100/200 cell etc)

Yes..worse if you get caught with a hollow one.. that shows intent

But If you've got an aftermarket one and you get tested your still screwed...

Were all navigating a minefield.. its just if or when you get done...

I agree, in SA 100cell cats will still get you in trouble, so I just bit the bullet and went straight pipe myself.

Cars sounds amazing and gives off not much smell at all.

Plus you get this :)

it's not the actual wheel overall diameter that causes a difference in readings, it's the placement of the weight

Do you get flames when accelerating or when backing off?

Lol...that's what you get when a tuner is too scared to run a decent A/F and instead runs it rich cos he tarded.
