Kit and head price? You guys aren't at sea level are you? Do you compensate for levelation to give these numbers?

x2 on a price for the kit. Does this require a fuel controller? If so what one are you using and do you have a "base" map for higher elevation riders 6-10k?

Retail for BMP Durability kit is 499.95 and BMP Head is 399.95

These are STP Corrected numbers, All naturally aspirated sleds will loose power as air gets thinner or warmer. STP Correction is the best way to compare day to day results. We are just showing gains or loss with products installed comparing apples to apples.

No fuel controller is required for Package as shown in graph when running on Premium 91 octane NON-oxy/eth

Apples to apples

Not really, you said in your earlier post that the pro looses power over time (I asked why is that do you think? no answer yet). You are comparing apples (new rebuilt engine) to sour apples (1800 miles engine which looses power) so dyno a new stock pro and lets see the difference. 15 hp increase is pretty cool though. Sexy pistons too.

This exact 800 made a consistent 150-152HP when it was brand new.

He has answered you. Maybe you have already seen it HERE.

interesting to see the higher rpm hp range compared to stock
stock 8000-8100 usually your kit 8200-8400
do you think it is do to the lighter pistons ? and what about the rev limiter?
i thought it was close to 8400 +/-
thanks

I don't understand your post. Conventional wisdom is to clutch the stock CFI 800 at 8250rpm.

I haven't seen a rev limit below 8500 rpm

what makes your kit better then the other kit on the market why should we by your kit when you are 100 plus dollars more for same type drop in piston kit on the market

Well IMO he has posted enough info for you to make a informed decision. There is no need to drag this into another vendor crapping on another vendor thread.

I am not an engine designer by any means, but I have heard several other high performance engine builders claim that larger crankcase volumes actually produce less horsepower.

 

[tdorval]

I've only heard one builder mention that the added crank volume could produce less. When asked if they tested it the answer was no. Consumers running kits with spacers that actually used the products all seem to report gains from what I've read on here...

Detailed photos along with dyno results, good on ya. Can't even get that if you ask from most aftermarket companies.

A statement like that is similar to saying "aftermarket reeds always produce more HP than stock". Either the statement is being taken out of context or the person is blowing smoke. The "real" answer depends on what motor you're discussing.....

Duh!!??? I think we are in the Polaris Pro Ride section, last time I checked, so this statement is specific to this motor.

I'm curious if a lot of that ain't sales pitch talk. This is the internet ...

Does any body have solid proof that isn't associated with trying to sell one of their kits.

Sooo what did u manipulate the first dyno run to get it to be 144hp on the first run?
