Can anyone tell me now much HP to expect with all the mods i have below? I am getting a before and after dyno in about 2 weeks, just see what to expect

 

I just the results for my Raptor with just the HMF exhaust K&N proflow filter kit and dynojet kit. The resultes were only 39.5HP!!! That is really low. I do not havbe my lid modified at all. How much of a differance would thatv have made? I told them to rejet the carbs with the lid off when they get done with porting/cam/piston. how much HP should I expect to see with all the mods when fineshed??? Thnx

 

I read in dirtwheels with about half that stuff it came out to 44 horse power.

 

I would think 53 to 56 horses. Let us know.

 

Does anyone know what pipe would react the best to engine mods I know the CT claims 48hp with just that kit. Des itreact wekk to internal mods

 

Skyquad- this has been debated on this forum a 100 times, no clear cut answer. I believe they are all close. plus, minus 1 1/2 hp. Untill you REALLY go wild your hmf should be okay. I have run against many piped raptors, to me the jetting seems more important than the exhaust. Do a search, raptor720 has given lots of info on this.
