NON step 35 Top Speeds

My 89 10 meter has 468 blocks with 088 heads and 177 blowers. The motors made 610 hp on the dyno. I have trs drives and with 28 bravos or 26 hydros I run the exact same top speed of 75. The boat handles better with the hydros and both sets of prop spin to 5000. I have been debating switching to bravos and probably picking up 10 mph.

I put the smaller pulleys on doing 8 pounds of boost running 5 blade hydro p5x . The boat loves the p5x hydros got 93 out of it. light loaded of coarse.
