What kind of Horse Power are some of you 400ex's pushing???

They all offer a great improvement above stock (like double its stock power).
TC426 :12hp
CT440 :12.7hp
LRD440 :12.8hp

Sorry...couldn't miss this one...
I really can't tell you since I don't even know what's in these kits. I think the stocker runs around 28hp (from mobiledyno)...expect the big to run in the 40 something...just a guess.

I could believe the 52 hp for the 473 but you guys claiming 36.5 with a stock bore/stoke and carb, come on! You got to really work a 400ex to get that kind of HP. Don't believe these claims that pipe manufacturers advertise. A few months ago a magazine did a test on most of the top exhaust systems and the most you are going to get out of a pipe is about 2 hp. A air filter mod will give you another 2 hp. To get some really juice you got to get deep into the engine and in most cases, with heavy mods you will get low 40's. Now I'm talking about something that is reliable. You could probably build a 60 HP time bomb running alcohol and NOS but realistically low 40s is what a highly modded 400ex will get.
