What does going to a higher pound radiator cap do? I am pushing too much water to the overflow using a 16 lb cap. Will a higher cap keep it in the radiator?

It will raise the boiling point of your coolant.

yes, a higher pressure cap will solve your problem. use at least a 22-24 psi. cap. i use the highest rated one i can find......stant makes one rated at 28-32 psi.

Just make sure you have a good rad and clamps!! A 30lb cap can double the pressure in the system. So if you have an old rad that's been beaten around some, there's a chance it'll split. Most new 'race' rads can handle it without problems. Although double clamping hoses or using T-bolt clamps is a good idea. I've switched all mine over to these. http://store.summitracing.com/partdetail.asp?part=SME%2D240225
