Negatives to running a higher pressure Radiator cap???

Just wondering if there would be any negative effects to running a 15psi cap instead of the 13 psi cap on our cars?

My GTU cap failed and spewed all my coolant out killing my engine.

I am never buying a Standt cap again so I am looking into other options.

I've seen Greddy ones which are for FD's which are rated at 15 psi/ 1 bar.

Other than not popping opne at the regular pressure I can only think maybe a hose popping off.

Any ideas????

I would personally run the stock Mazda cap, but I know people that run the greddy cap with no problems.

From past ,up to a 17lb cap should be ok for street use. 15 no problem.

Why anyone would pay GReddy prices for radiator cap is beyond me.

If you can't keep the engine from boiling with a considerably cheaper Mazda cap then you have a major cooling system problem.

At 13psi above atmospheric water boils at 260degF. Do you really want to go higher?
