HP Race Kit and PCV

maddrama · 01-13-2013, 04:42 PM

I have a question, This is my first BMW S1KRR. I have a HP4 which I put the HP Race kit on (control unit and exhaust). Will a PCV or a Bazzaz increase HP at all or not really? Thanks

I just dyno'ed my bike 2011 converting to a fulltime track bike., Added Full Akap shorty system, Pcv V, and Dan kyle block off plates. BMC race air filter. I could be Wrong here but I think the Power commander is more for Fuel map and Making the bike have a good power curve not so much adding horsepower. I ran it with 93' octance pump gas. Going back in a few weeks and going to run MR12 Race fuel should make 4 or 5 more hp. I had 10hp more in the mid range then someone else running akap with the long pipe. but he had better top end #'s which I expected. But on the track more mid range is better.

Dyno Chart.
DynoJet Machine was a 250i

Thats what I had thought its primarily for optimizing the fuel map... I dyno'd mine and it had a smooth curve and all but I read somewhere that someone picked up 5HP just adding a PCV only to the HP4 and was wondering. Thank you

Your bike made some good #'s. Going back and running the 2011 with the MR12 fuel and, going to get the Hp4 dyno'ed after the 600 mile service. I'll post the #'s

Yeah Thanks... I think I will pick up another 4-5 after the motor loosens up a bit. I only had 33 miles on it when I dyno'd it. To be honest I thought it would have been more. I was under the impression S1K's came with 193 to the wheel but I figure thats crank numbers now. Either way the bike is pretty fun from the short time i got to ride it...

Getting a PCV or Bazzaz kind of defeats the purpose of getting a HP race ecu, does it not?

I believe the hp race kit does a lot more than mange fuel .

You don't need a pcv,you need the software for the kit ecu-then you have the facility to optimize everything on the dyno.

Well it removes the cat and supposedly its different in the headers and can. Also has a totally different ECU map. I was just curious if a management system would improve the HP on top of the race kit.

Do you mean the calibration tool?
