Most accurate yet.

About 37-38. The California models have about 32.

The mods MAY put you into the high 50s, mids are more likley.

Stock is mid to low 30's. Dyno-proven all across the country. State of origin doesn't matter. California Raptors make the same amount as ones from Maine. Most any pipe will get you to the 40 hp mark. Ditch the airbox lid and get a K&N and you'll be in the mid 40's to upper 40's. You're not going to break the 50hp mark without going inside the engine. Throw in an 11:1 piston and a Stage 2 cam and springs, and you'll be sneaking up on the 55hp mark. The Stage 1 cam is also a little better suited to woods riding than the Stage 2, as well. The price per horsepower starts going up pretty dramatically from there. For something used in the woods and on trails, you really don't need anymore than that, though. The stock suspension really starts to show it's weak points with this much horsepower.

are u kiding me ... with a high comp and cam u might get 50 ... but not with the gytr pipe they dont give u too much power ... ct pipe brings u to like 46-48 with the fro flow kit and the piston will def bring u to 50 so .. i have no idea wat ur talking about were i got 50 from

[chazekxt]

34

[Blue_Streak23]

Let me correct myself. I researched it, and stock they have 35Hp.

[TacomaNC4X4]

well i can tell that it all depends on who you talk to..but really...it all depends on what color you got

[raptorrider686]

42hp. Is where you HP stands as of right now

How are the edlebrock fcr carbs for the raptors, and how are those aluminum airboxes? also are the HMF pipes good on them? Thanks, any info will be appreciated.
