496/425 353 about 70+ MPH now you guys say 85 MPH with 525 ? Did it

yea right once no never!

There was one guy claimed 90mph in 353 late model It was at Dewey Cheatum & How high dry marina but he flipped it never got a ride??Not sure power maybe 2X565 HP?

There is no comparison in power. Every 525 made made at least 550 HP.. You are talking a total of 250 more HP plus boxes. Figure 1 mph per every 15-20 HP, plus the boxes and you can do the math.

downhill?

If it had 600's and boxes, its possible. Very few made with those motors.

According to this Youtuber, that toured the factory and posted this video this year.
Call them up with cash and order one.
According to him, (he shows a glimpse of one in the plant) they will if you have a sizable deposit.

My next boat gets outboards. I'm only 39 and I'm DONE digging around in a bilge. It's damn pretty boat, but doing all my own work means. NO thanks to inboards. When you can slap 600 HP twin speed dual props to the azz end of a barge and do 90... good 'nuff. The FasTech's just lost out to modern boats. Sad... cuz... I have a FasTech lol.

I toured the Formula Factory when I was 15. It's next level that's for sure.

Why is it so hard to beleive a 353 with 525’s can do mid 80’s? Shoot a longer heavier 38 ts top gun can do mid 80’s with the same power…am I missing something? The 35zr’s with 525’s will run mid 80’s all day long. Likely upper 80’s.

To the OP, good luck in your search.

what part of CT are you in?

Boat test 353 FASTECH 2x525= 52mph@3500 and 80mph wide open 5300rpm empty with expert driver! PS some hulls are faster Donzi Fountain Cigarette etc! All hulls a little different!
