Im surprised this didn't come up earlier. Yes it was 76mph on the GPS. Its a great running little boat. Im a pretty big fan of the 525SC but will give most of the credit to the hull design.

Had a pair of 525 SC's for 7 years and never did anything other than change oil and spark plugs. They spent their entire lives with Super Chillers and the boost upgrade pulley kits. These were bone stock 525's and made 600+ HP. Sold this rig some six years ago and from what I hear they're still running strong. Intercooling a supercharged engine is the best way to get more power, thru higher boost, without hurting the reliability. Check into the chillers and the pulley kit to get you to 7 - 7.5 lbs of boost, bolt it on and just smile! :D

That was the beauty of the 525. It had so little comp to start with that you really could boost it up pretty good.
My guess would have been to upgrade the exhaust to a tube header and then get the prop done by BBLADES. Prolly pick up way more than 4mph. |

What was the stock overall timing for a 525 sc, and what was the stock boost setting with the factory GIL exhaust?
|
What is your drive height? Fountains were usually set up correctly but I would check that first.
