Engine from 2013 Bmw HP4(competition model) with 3,800 mileage. Some people will argue that the s1000rr engine and the hp4 engine are the same but are not internally. There is a reason the hp4 was $36,000 and the s1000rr is $20,000. With that being said, I dynoed the hp4 and stock the motor put out 193HP. I have dynoed three other s1000rr fully tuned with full exhaust, air filter, etc and they only produce 185-188. People are getting 215-220hp out of the hp4 bikes/engine. Hp4 engine complete: $5000. I have a video of it on the dyno, etc. Tons of other competition Hp4 parts available. Text 7276788904 for your needs. Thank you.
Hand selected parts were used in the hp4 engine thus creating less weight on rotating mass. This would result in more power(5hp). The s1000rr engines were mass produced which would explain occasional engine failure. Hp4 engines were hand produced from BMW techs. Has anyone EVER seen an hp4 engine fail? Because I haven’t.
Purchase it and find out. A significant amount of modifications may need to be done though. The Grom May start doing bunny hops.
I'm just saying, I know dynos are different. My friends s1000rr put out 193 RW, with just a full exhaust Akroprovic
Yea, and that’s about all it will make. The hp4 produced 193 STOCK. No tuning or anything. Straight from factory.
Essentially the Hp4 is a “blueprinted” stock engine. You can do the same with a standard model and some standard models might make similar power. Price is fair for the motor.
I disagree. The S1000rr and hp4 both have the K46 engine appearance. However, internally hand selected parts with less weight were used thus creating faster rotating mass on the engine allows a roughly 5hp increase on the hp4 over the s1000rr. Not to mention the upgraded electronics package the hp4 has over the mass produced s1000rr. I have never seen an s1000rr fully tuned pull a 193 on the dyno. The hp4 pulled a 193 stock with factory tune. My other hp4 is fully tuned and I easily got 200hp on it. Full Spectrum Racing tune.
