Every OEM and major racing team in any motorsport uses dyno’s. They tell the tale. Bobby, you’re falling victim to the age old issue of the older I get the better it was. A new vehicle with 707 hp would run off and hide from an LS6 Chevelle. Actually I bet you’d be amazed at how many new cars would outrun an LS6 in the 1/4

I remember when that convinced you guys that stuff was fast ..
Cuz the way I remember it, bout the same time, some LS-6's grew to 707 ci and, well, mo bigger ..
Went 6.50 / 211 with this one in the late 90's ... you ... ??
Come to think of it, I got a safe 700 horse two-wire tune up if ya ever want to throw it on top of your 1300 horse mule ... jus-sayin -
BTW .. Peanut man, them motor's ya'll gotz look dayum nice

Thanks man!!! Been a long time coming and went thru a bunch of obstacles but finally got it where it needs to be. The new ignition and fuel delivery will be just icing on the cake!! And cuda 707 won't be a problem for the 3.5 with some spray and with the sleeve design it has she'll take a whole bunch!! lol

That must mean I`m getting old. Yep, And damn proud of it. I know they use dyno`s as a tool and that's ok. Think about it like this tho, Mercury made a 2.0L champ motor that made 300 advertised HP. Then they made a 2.5L Drag motor that made 300 advertised HP. Are they the same? HELL no. Will the 2.0L run with the Drag, HELL no. I`m just pointing out that dyno`s don`t always tell the whole story.

I bet the torque numbers down low are way different and the Drag really makes about 330-340

Merc used a dyno to tune and design the 2.0 but it probably was not SAE nor was it up to today’s standards. I know one of the best in the Outboard world found a 12% difference between certified and not which is where most of today’s high claims come from. That’s true in all forms of dynos from diesels to jet skis...

Please keep in mind that this is only a conversion and not ment to be anything negative about the CTR engine. I`m glad they are making them since Mercury stopped and would love to have the big one on my boat but that can`t happen unless my powerball numbers hit lol. You never know.
