laszloO1 , when you did your motors who flashed the computer, Set the I.A.C. and T.P.S sensor?? or did you have a scan tool??

well keep in mind you don't need to set boost to 700+ HP onw could choose to set 3lbs probably around 640hp, and the drives should live, maybe a little longer:ernaehrung004::cool-smiley-026:

the boat is a 42 poker run im looking at with 525efi's with bravo xr's, does anyone know what hp rated the drive's are and if they will live max'd out?:asskiss::hitfan:

Most likely bump to sportmasters to handle the new power.

XR comes standard with a 600sci, so you should be fine up to around 600-650hp:ernaehrung004:

I have a 38 with 600s ITS sportmasters and lost 2 uppers in 125 hrs the 42 pokerrun should weigh about the same. That sounds about right no more than 650.

Whippled 525's work awsome! HTG Marine on Grand Island,NY can install and give you a turn key package...tuned , propped and dialed in if that is what your looking for. It takes 1 week...don't miss a weekend! Check it out at www.htgracing.com or email at [email protected] We have 39 Velocity ,40 Baja and 32 Sunsation with Whippled 525's....no problems. Can also make you a nice deal on kits if your installing yourself.

Do a search on 42PR drive issues.

They have a rep for being hard on drives with stock 525's, I think your asking for trouble putting more power to them.

Maybe look into upgrading to Teague Platinums or the high end Imco, if you want to spend the $ , re-rig with #6's.
