That is really impressive numbers. I never would have guessed it. I would be elated to have a basically maintenance free cat like that.....if I could afford it.

Top speed on a large cat with 525EFI's can get into the higher speeds. Just be prepared to hold the sticks down for a long time. The trick is to run smaller gear ratio's but keep the pitch up. As your slip comes down your speed can still hit those top numbers. A lot of the top number is based on the top RPM as well vs slip.
I know with Bob's race boat (368 Skater with BONE STOCK 525EFI's) has run just under 132 in a kilo but averages 115-130+ in normal race set-ups (depending on water conditions)..
I would imagine a 40' MTI (Awesome boat!) would get to 125MPH w/ 39's or 40's on it... This boat should have no problem getting down into the 8% slip or less on the big end..
Some people don't realize the difference between a boat set up for 525's vs. a boat with bigger power. It could be 2000+lbs, depending on the glass work and all the extra goodness installed. Weight placement can also effect the top speed.
140MPH is hauling ass even with big power, but it depends on how it is propped and set up. Honestly, would you rather had a boat that accelerated like hell to 140 or would you want something sluggish to 150? Either way your hauling ass but the acceleration is the fun part, because you are probably going to have an average cruising speed of 85-115? Boats are fun because you never really know what they are going to do until you get out there and do it!
I don't know if this makes sense or is on point, but my 2 cents -Eric

I drove Randy's 40 Loriblu / Fastboats.com 40 MTI @ 125 plus with 4 people on the boat last year on the lunch run in Islamorada FPC run"...
Fun boat and a lot of fun!!!!

I have always been impressed with the numbers they get out of Cat Lite, prop technology has really opened that door. Bob raced with us in OPA'a Class1 a time or two when we were still running 750 Supercat motors we couldnt catch him. Just out of curiosity are these top end numbers with crash boxes and if so what would switching to a shiftable trans do to top end?

Very, very few boats have the recognition of Speed Racer. I can't imagine what it would be like to pull that boat down the road, let alone to have it on the water. The 525's seems to be a great mix of speed, reliability, and fuel economy. The dirtiest spot on this boat is cleaner than anyplace on my boat. I'd hate to see it leave LOTO, but I sure don't have the checkbook to keep it there.

So here is a question. Why are the big cats, i.e. 368's, 388's, 40's, faster with 525's than a 30 or 32?
I understand that they have a lot more tunnel surface area, but they also have more weight and loads more aerodynamic drag. Does the tunnel size really make that much of a difference? What is the fastest 30, or 32 cat with 525's? I certainly cant say that I have ever read about any of them approaching 140mph.
