Well Happy with 141
« on: 13 October 2015, 04:55:34 pm »
A couple of hours on the dyno with Ross at Ian Bell Motorcycles this afternoon has resulted in a smooth fuel map, bang on fuel/air ratio across the rev range and a peak of 141 bhp and 73 ft-lbs torque. Graph below.

Mods carried out to the bike:-

1. AIS feed pipe and airbox connection blocked off with well nuts - will remove AIS pump & pipework and blank off properly at a future date
2. Airbox intake mod with K&N air filter fitted - no issues with sealing airbox!
3. Headers gutted - ie cat removed - no EXUP valve
4. O2 sensor removed from headers (hex plug fitted) and eliminator plug fitted at electrical connector
5. High level exhaust (Holeshot link pipe with SP Engineering end can - no baffle)
6. Secondary flies removed
7. PCV fitted

The bike appears to hunt a little at idle (but so does my GSXR!) and pulls like a train thru the entire rev range thru all gears. No popping or farting on closing the throttle and sounds bloody awesome.

Thanks to Slappy for his Juicebox Pro map which I used as a base map. Quite happy to share my PCV map if anyone is interested.  :D

Nice result,  glad your happy with the result :D
Similiar hp to mine but each dyno  differs and temp and humidity  can make a real difference, still got to get mine on the dyno at Jordans to see how it compares to the results from RaceHQ.
Your torque figure is better than mine by six :\

My dynojet reading read 5bhp higher than my dyno dynamics run. Commonly dynojet run a little on the higher side. still very impressive.
