What in the world does a Kilo record have to do with a TCM800EFI?
The fact of the matter is extremely simple, and I can back it up 100%. The TCM800 EFI, as it is shipped makes well over 800HP in standard correction, which Sterling and all other custom engine mfg's use (industry standard). Some can vary that number and make they're own correction factor, but using Superflow's, which takes baro, temp, humidity reading shows this motor makes a consistent 850hp. I know this because I just spent 1 full week on the dyno, and nearly 100 runs on one and never did it make less than 800, not even close. In fact, it makes 820-830 SAE HP which is what OEM's are suppose to use, such as Mercury Marine.
Now lets talk about Mercury Marine. I just spent 3 weeks with a 600SCI and 1 week with a 700SCI on the dyno. Standard correction factors, the best runs for the 600SCI was 580HP. The best for the 700SCI, 669HP. I do have to give it to Merc though, the 525 consistently makes 545HP. SAE numbers fall far below except for the 525 EFI.
So, when talking about numbers, some may fudge, some may not run on good dyno's, etc, but I know for a fact that the TCM 800 is understated on power, as is the TCM 900. Both make consistently 25-50HP more than advertised.

Curious what your experience in the dyno room or anywhere else shows.
So Ive gotten 3 independent data points to back my post now, and you've supplied about as much useful info as the Apache Chief character in the super-friends.

Now I know the 700 has torque from the blower, but I also think the NXT and most notably the SSM props are way more efficient than bravo props.
Moral of the story, NASCAT wiil hit 143MPH compared to 135 previously with nothing but drive change and better props!!!!!!

Very interesting thread Nascat. I have left 2 prop's and two broken shafts on the bottom of our lake this summer, Imco SC's and 710's in my DCB F29. Idling back on one screw at 8 mph SUCKS especially when it happens 25 miles from home. We are waiting for parts AGAIN, hopefully will have her back on the water before the weekend. When the Indy drive came out I thought it looked great (expensive) but dropping props and shafts every 10 hours is getting costly too. Do you have an estimated total of what this swap is going to cost? Feel free to pm me if you want to keep this quiet.

This project is NOT for the faint hearted or "do it yourselfer" unless you are very organized, multi talented & can stomach seeing your perfectly good paint work & rigging spread out like a 1000pc puzzle
Engine relocation affected header clearance which required new scoops. Bilges were touched up while the engines are out.

I believe I mentioned the fact that my application won't accomodate plug ins & is too tight for a driveline.
Skater custom assembled a flange/flange u-joint which is why engine-drive alignment is so critical.
Port drive is on for good & expect the remainder of the transom to be final assembled by mid week.

NASCAT.....Boat looks great....
R-RATED....Tyler on Trottles = need Indy drive.....
Put 2 Ilmor 625's and Indys in that Fountain....that will make your boat Tyler proof....
Thats was one of the factors we look at...the money you put into a XR, IMCO,or Teague to keep it running, the Indy is worth the small investment...its no differant then the 525/#6 package..other then your almost over 1200lbs lighter and save a chunk of money with the 625's/Indy package....
Congrats on the win....boat ran great...
