2012 HCR BDturbo 9psi/2000ft

[Crusty82]

Hi.
This is my 2012 HCR BDturbo running 9psi @2000ft on pump gas

My first helmetcam ride, so it`s not any good, but you get an idea of how it`s running.
I don`t have much to compare with, so give your honest opinion on how it sounds.

Normaly I run 10psi, but because of very light snow with a hard base, I turned the boost down. It goes up to 80mph trackspeed in 2 seconds.

I think maybe I should try to gear it up to 22/48, and change the track to challenger extreme or peak.

I will try to run 11psi this weekend if I find a spot with some heavy snow.

Are you running any timing keys?

 

[Crusty82]

No. but I have tried that to.
-stock head with timing key and 6psi
-rktek turbohead at 12psi with timing key
-rktek turbohead at 10psi without timing key (this is the best setup i have tried)

I didn't like it with timing key. The on/off throttlerespons wasn't as good, and It was much harder to tune and clutch.

Nice vid looks like it runs good. Where you riding at?

My 2010 at 1,000ft I usually run at 8 psi but have taken it up to 12 a few times. My trouble is my cat is a 153 with a 2.5 CE on it and it catwalks much worse than yours after taking that 2.25 powerclaw off. Now 12 psi is almost uncontrolable but sure is fun to try tame!

So much fun I cant believe its legal

I ride in the southern part of Norway.
Yeah, I hear the challenger hooks up real good
The conditions I am riding in on the video is the worst conditions for hook up this winter so far. So normaly the pc 2,25 do just fine
The rockhard base underneath takes away all the traction..

Do you run a modified head or do you run better fuel?

I run straight 100LL fuel and the stock Ho head with a resistor in the pipe temp wire pulling 3* of timming from 6000rpm and up. I also ride mine out in the mtns at 8000-10000 ft is the reason I left the HO head on. If I only rode it at home at 1000ft I would cut the head for sure.
