What is a sfe rpms for 525 efi with whipples?Dustin says to turn them 6000 and when summer gets here it will still turn about 5700-5800.Is this to high for stock 525's.Old rev limiter was set a 5450 and dustin says he's test that the 525 was still building power at 6000- and set the rev at 6200.I think its to high and want the rev set at 5800.Am i wrong ?

I think that you should have them set at 3500 rpm, that should be perfect!!!! I should be able to run right with you at that. Motors will live all summer...........

That sounds good but i think i was running about 92 at 3500. Hampton is going to be fun this year. hang on girls and no James you can't help them hang on.

Stock prop range is 4600-5200 if you didn't change the valve train and do a bunch of work in the bottom end I would stay down under 6,000 It may mean the difference between floating at the dock and boating all summer.

After re-reading your post, are you using the rev-limiters to control wide open throttle rpm? Or does he want you to prop it to turn 6,000 rpm's ? Ed

better to be safe than sorry. take the whipples off and send them to me.

Prop it to turn 6000 plus it still was building power at 6200.

G you have to come off the $$$ cause have you ever seen a hearsh pulling a u-haul.
