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!

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.

Be careful of just adding the smaller pulley without lowering the timing down to 30 or 32. I also sent my carb. out to Nickerson for a rebuild as the engine was very lean before the rebuild after adding the pulley. Last idea may be to go to big tube headers from CMI or Lightning.
