BMP 860 Big Bore and Durability Package

[tdorval]

Has anyone else noticed BMP is advertising a new big bore paired with their new durabilty piston/cylinder spacer? They are claiming 184-185hp. I saw this while browsing around and wondered what people thought of it. I know some places might exaggerate their HP findings a bit, buts its one of the first CFI-2 big bores i've seen that posted a dyno chart.

If you do the can, looks like it is about $4,000ish. Includes an exchange of cylinder block and exhaust valves.

It is a little more money then some but that would be with the team tied, pipe, can, and pcv. Just seems like an impressive number compared to the 175-180 for the 910 on twins is all. I most likely won't be running this, it just peeked my interest so I figured I would see what the thoughts are on it.

Smoke and mirrors....not to bash their stuff but come on...enough with the BS dyno #s already. This has been going on for years.

I wasn't sure what to think. The numbers for their durability kit seemed reasonable so I was wondering if they have improved on their Dyno reporting. Guess not.

If they will send me one of their kits I will give you a honest Butt Dyno report

Brought my Pro to them last November and it was actually the first '11 Pro 860 BMP did. Full kit, obviously didn't have the reliability kit then. Dynoed at 180hp with high compression head and 110 octane. I generally ride at and above 8700 ft, been mixing non-oxy 91 and 110 along with a shot of oil, suppose to be able to run straight 92, just added piece of mind. No DET codes and engine rips, throttle response is instant and pulls hard. Brother-in-law has '12 Pro 800 with SLP stage 4 and this 860 will pull about four sled lengths on it. Biggest difference I could see from riding both was the 860 has way more bottom end, jumped back and forth between mine and his and track speed increased noticeably quicker on the 860, as it should. Still not the performance of a turbo, but then again I didn't spend the money of a properly set up turbo kit either. Happy with the set up.

Where did you have your sled dynoed?

BMP, when the fuel map was being programmed

Interested in this as a possible alternative to other hop up options. How many miles?

 

[tdorval]

Gotchya, I was hoping you were going to say at a third party shop somewhere that had no vested interest in seeing a "high" result.

 

[Pro860BB]

700 miles on the 860 kit

 

[tdorval]

Does anyone know if BMP dynoed this as a race gas setup like pro860's was?

 

[philsummers21]

According to there Dyno a stock Pro should be clutched for around 7800. gain more torque and only lose like 4hp then clutching for 8250

 

[tdorval]

Resurrecting this. Curious if anyone ran this all season and how they liked it. Most likely sticking to the turbo's but you never know...

Dyno numbers from BMP... lol

I'll eat a little crow on that statement (bad experience years ago)... Rode one of their 900 cats and was very impressed at 9000'... Would love to see one of their Poo motors in action.

A "historic" motor if powerband and #'s are true.
