How many hours is safe before a rebuild on a 2000 500 efi motor with a whipple @ 6 lbs of boost?

Thanks

The company that installed mine got close to, or more than 500 hours out of his. He had twin Whipple 500efi's in a 32 Sunsation. They are not far from you, just over on grand Island NY . I put mine on with a little over 300 hours. I will pull the engine to rebuild it once I get close to 500 hours.

Change the head gaskets when you do it too.

Alot of the lift of the engine will be in how you run too, of course.

Rob @ HTG?

Yah, Rob at HTG raceing. Before he pulled the engines out, he threw a small pulley on the blowers and drop the boat in one last time for a speed run. I forget what number he got, but when he pulled the engines apart, one piston had a piece missing.

Anyways, give Rob a call, he has installed many.

Have a friend looking at a Baja 272 with that setup with just over 350 hours. Don't want him to get into a headache.

Were head gaskets upgraded? Did the owner change the valve springs yet?

The hp500efis have all kinds of info loged into the computer. Can you frined get the seller to print out the history? Hour many hours excatly and how many at what rpms. Tells you alot about how the owner ran the boat.
