09 HCR bd boxs numbers

[ArcticJunkie]

Hey I have a 09 HCR with a speedwerx low alt full pipe n a RKT head 13:1. I live in MN also ride out west. But I was just wondering if anyone could give me some numbers to start out with that would be great!!!


Also thinking of having RKT porting done as well. What do you guys think of it n has anyone ran it at sea lev.

Thanks

Nobody has any info for me not even on the porting???

Porting is huge on the 07-09 sleds, it also works well with the SW pipe.

As far as altitude, Kelsey also tests at only 5k for his stuff, so it should be fine down low.

I have RKT porting, RKT 13:1 head, and speedwerx 925 pipe on my M8. The fuel maping is much richer on the 2007 so I do not think my BD numbers would help you much. I ride from 0-4000Ft. it runs good, smooth, crisp and no bogs. Back to back with another 2007 M8 there is no comparison with most of the gains being in the mid-range and top-end.

Alright thanks guys. So the porting is worth the money then and Jason you can still run that on 91 right

I run 90 octane with no ethenol.

if your going to spend the money on the porting buy egt's then you can tell what your doing for each elevation!

Yes I have egt's on it already. I just haven't really had the time to mess with the box yet or really made time to cause its been below 0 for about 3 weeks now!!! Hopefully it'll warm up pretty soon. Are they still reliable with the porting too?
