There is a good chance that the degas bottle is crap.

Re: new parts same problem.

ok so the tank thing could be bad and causing the coolant to keep coming out the cap?

what causes these to go bad is it normal?

Re: new parts same problem.

How's the temperature of the car? does it run hot/cold?

Usually the higher RPM of the water pump isn't enough to cause excessive pressure/overflow/coolant spewing from cap..

A bad cap or leaking bottle would typically leak any time the coolant is warm/under pressure

Does the bottle look cracked where the coolant cap screws on?

Could be a pressure leak elsewhere in the system, or an issue such as head gasket..

Re: new parts same problem.

How old are your radiator hoses? Are they collapsing? Is it the original thermostat?

Re: new parts same problem.

new thermastat came with the intake(one with aluminum coolant lines)........i did find out it leaks no matter what rpm.........and its only coming out through the cap/tank, no other places.......you said something about the hoses? do you mean like there blocking the coolant its self? if so i may be wrong but but my heat works on and off now that theres basicly no coolant in the tank i don't know if that means anything.
