Im wondering how long i could expect a set of bravos staying together with a set whippled charged 500 in 30 spectre

as long as your running her on a lake or have a deep X-dimension you should be OK...bravos and cats dont like each other

i had 500's and B1's and they never even flinched, the 30 is pretty light and doesn't put a tremendous load on the drives, although whipples 500's are gonna put out more than 600 HP... it should be fine, especially if they are XR's...

I've had no problems with my Xr's. 675hp N/A. Having a tunnel tab to ease it up on plane makes a big difference as well. I can get on plane and never go over 2500RPM.
