Hey guys it's the worst introduction i've ever seen, from BluExplosions! lmao
This is what you need(in the center sfx table):
Spoiler:
if (tab = the_car.getSfxTable(1))
{
tab.clear();
if (dynodata.P_turbo_waste > 0.01 )
tab.addItem(new ResourceRef(parts.engines.ENGINEFOLDER:0x000000IDr), 5500.0, 6000.0, 12000.0, 0.50, 0.80);
}
