everybody is missing the whole question of the thread... more or less whats the horse power of the 3.3. i know it is claimed to have 60% more power than the 2.5 that dont tell me nothing. i know the o.s. is a much better motor... i know this and so does everyone else. so again whats the h.p of the 3.3?

yea "a claimed 2 h.p" that says nothing i could say it has 2.5 h.p but that could be a claim on a web site i found who knows. the link you provided really didnt give to much information on the subject.

Traxxas does not post HP numbers so you are going to have to look at some place that has put it on a dyno to get your answer.
If the 2.5 made 1 then the 3.3 would make 1.6
But according to the dyno the 2.5 came out at .69 and the 3.3 was .97. But since those are real world numbers not many folks pay much attention to them
Traxxas TRX 2.5 Rear Exhaust 0.69 @ 29,750 rpm 30.72 oz-in @ 18,750 rpm 38,500 rpm
Traxxas TRX 3.3 Pullstart 0.97 @ 31,250 rpm 37.49 oz-in @ 19,500 rpm 37,750 rpm

I remember Xtreme rc dynoing the .18TM and the 3.3, the hp was 1.12 for the tm and 1.09 for the 3.3. They were also described as the tm being more torquey and the 3.3 being more rev-happy

If you looked at Bentgears post where we tested both
2.5-.7hp
3.3- 1.0 hp
Which is about 50-55% more power out of the 3.3 compared to the 2.5.
I can argue all day why the X-Dyno is the only number you should trust.

it was posted after the fact that the question was asked a couple times.

But the location to find the information was given in my first reply, You just didn't bother to follow up on it.
If you happen to go to the site you will also find the numbers for some of the OS engines. The only downside to the test is I would bet the Traxxas motors were dyno'ed using the stock Traxxas pipes while the OS engines may have used a slightly better aftermarket system. You won't find the graphs showing all the HP and torque curves. Have to look at some older issues of the mag to find them. The graph is where you can really tell what an engine is doing. Peak HP and RPM don't begin to tell the whole story.
Derek, if you are still following this thread, thanks to who ever came up with the new system of mid range average HP and torque.........that adds a lot of info if you can't visually see the graph.
