357 SR1 Top Speed
Just curious what other 357 owners are running WOT.
I ran 66 on GPS with a trim tab dragging the water. That was at 4900RPM.

Supercharged 454's. Full Throttle said they were SC525 Clones.

Re: 357 SR1 Top Speed
Those RPM's are way low. You shure you are trimming it up enough? What is up with the dragging tab?

Re: 357 SR1 Top Speed
Mine only does 60 on GPS @ 5000rpms, I have fresh 420's...How did you fit the 525sc's in there? I did all the math and came up short 3.5 inches. The engines are to high and hatch is to low. The TRS drives makes for a high engine mount, my gil exhaust is within 1/2" from touching the hatch.

Re: 357 SR1 Top Speed
It is TRS, the hatch is raised but still makes a small amount of contact on the arrestors. The trim tab would not respond. I was a bonehead and forgot to check the fluid level in the pumps. They are all full and the tab now works correctly. I had problems triming the outdrives. The tab markers all need to be adjusted. Plus the starboard drive moves slower than port drive really making it fun to adjust.
I am really considering changing the hatch and adding a couple of scoops. The Gaffrig flame arrestors are small and thin and I want to get more air in the motors. I am considering some large K&N Marine Filters on top of a stack in the scoops.
