Carpenter Questions

[Steel]

Well I did order the Carpenter headers and got the ecu flashed by them. I am supposed to get the stuff on Friday. Very excited about getting them installed and seeing how much of a difference it will make. For two grand I hope so lol.

Oh yeah, you will feel a lot of difference!

 

[Claviger]

Indeed

I will let you know, I told work I had an eye appointment so I could install the stuff and do some riding Friday afternoon if the parts do indeed arrive. It's ok to lie if its for the bike, right?

I'd sure like to know also. Are you going to measure it on a dyno before and after? What air intake system are you using with this setup? If you post a video file of the bike running I'd watch it. Thanks.

I can tell you that the numbers will be:
12Xwhp before 15xlb-ft
16xwhp after 16xlb-ft

It’s a known quantity as far as power goes. For intake side I’d suggest Ramair or K&N 1770. Both tested back to back without even Un-trapping the bike vs no filter on a 190whp Rocket... less than 1whp difference between them.

+40 hp on a pipe, a Air cleaner and tune?? Dang that's quite a bit. The stock motor must be choked to death.

It is, very much so. I can’t think of any other vehicle car, truck, or bike that has such a high % gain from just headers/flash. It’s crazy, but great for owners

Yes that's quite correct Doc.
We're getting about a 28-30% increase with my Viking pipe, this of coarse with filters and tune to suit.

 

[scot in exile]

I went from 169 to 206hp with the carpenter exhaust

 

[Dr.D]

Oh crap I'm a getting me a pipe boys, but which one??????

Actually I'd favor the Tq over the Hp if i had to choose. I do see a greater increase in the hp though can you tell me why a lesser percentage gain of Tq?
