160hp XB?

yeah, I went back to that link and read it all the way through until that kid came in..hahah He was quite a big talker. Im trying to imagine what 160mph would be like on a XB.. ha ha Ive never had it much past 110 and that was only for a second or two..just dont have anywhere around here that you can get away with it. But anyway dude said 160HP from what I remember and gave me a really big displacment figure and I belived him for a few min. To be totally honest, I was walking in to the club I go to with my gf the first time I ran into him and we had had a few shots in the parking lot before going in and I was kinda dazed at the time. Then as I was walking away from him, I was thinking to myself, how the **** is that possible without forced induction? How would his crank and rods take that punishment? Then I saw him about a month later on the street and he was riding like a ******* maninac. I guess he was trying to back up his story.
 
there is a bloke her in melbourne with a 1450cc xb. shitloads of power, and aparently goes great and reliable. no where near 160hp though either, but it has big kahoonas that for sure.
 
at 2guns.. yeah 1450 sounds right.. I think thats what he said. I dont doubt thats what hes got in there but like you say 160??? thats too ******* much.Maybe he said 140? I remeber thinking at the time it was the kind of HP that you would find in a 1000cc class i-4 or thereabouts.. does 140 sound reasonable for a kit like that?
 
If I remember right the XB12RR was pushing around 150 hp after ALOT of R&D and that was a full race motor.
 
I've done alot of research on the big bore kits on these things. The 88"=1450cc and the 90"=1550cc ish. With the 90", high comp, bigger injectors, big cams, head work, and good tune etc you can pull 135rwhp out of these things. However you're running beyond the ragged edge of structural integrity and design at that point and would need to figure frequent rebuilds into the equation at that point.

I had all the funds and sources lined out to do a 90" all out but backed out due to the long term reliability issues. I didn't have the heart to tear into a 2010 motor...just yet anyway.
 
All depends on how much $$$ you got.
You can build the hell out of any motor.
And with each stage it gets exponentially more expensive.
 
147 at the crank in an 1125 is a hella lot, don't really know why anyone would want more than that in an XB with it's short ass wheel base and suspension geometry.
 
www.nrhsperformance.com claims 124hp out of thier 1999 m2. They have a dyno sheet but I can't get it to post on here.


From thier website:
But don't let the low price and ease of installation fool you. These kits are capable of making some serious horsepower. Multiple customers have reported over 120 rear wheel horsepower* using these kits, totally streetable. NRHS's resident shop mule and errand runner, a 1999 Buell M2, pulled a whopping 124.8 rwhp
 
Well Ive built Mustang engines before but never a motorcycle motor so I have a pretty good understanding of internal combustion engines..they dude that has it can talk the talk, he knows motors I was I just couldnt decide if the HP figures he was giving me was hype or not.. I heard that motor and it WAS running HARD, I didnt sound like my mostly stock motor so I was sure SOMETHING was done to it. Who knows? Dude could be legit..
 
He could be talking 160 at the crank. That would still be a REALLY REALLY stout Buell motor but is at least within the realm of possibility. 160 at the wheel I call BS on.
 
When I see him again Ill ask him. From what I remember it was displacemnt more than 1300, he said he flowbenched the heads, different valves and I think cam profile..then the fuel system. He said the crank and rods were stock..I think he mentioned Axtell, maybe the pistons and the jugs. Does Axtell make a big bore kit? He was running a stock ECM with his own map. Stock y-pipe header, cant remember the cannister.. my head was spinning from a few shots I had in the car when I was in the parking lot a few min before I saw him standing next to the bike parked at the curb just up the street from the parking lot.
When he gave me his figures I couldnt believe it.
 
Ya know, 116 can sound like 160 if somebody's reeling off a bunch of numbers and specs.Maybe only 116 h.p.
 
Prolly the same guy that told our local snap on sales men(who rides a harley and has 2 older drag bikes) That his buell runs an 8 sec. qtr. Which he of course responded by scoffing and explaining how that sounded pretty f-in impossible considering his knowledge of drag bikes and what he had heard from me on how piss poor of a drag bike a stock chassis buell is.
