Stock base line was 43rwhp



A bone stock LTR puts out 32hp on KBR's dyno. Peashooter out, lid off and CB did 40hp 27.5tq.. KBR's reads low so any modded numbers are low also..

Good numbers for both indeed. I'm just commenting is all. Some dyno's read high some read low so it's anybodys guess to who's is accurate, but mods done on same dyno do say alot.. I guess a real accurate way is the actual percentage increase.??

I have been to KBR and I now there dyno, I helped Kam dyno tune a YFZ450 one afternoon. Rage ATV's dyno is the hardest dyno to get even 50rwhp out of trust me on this. There is no comparing dyno's anyway it is a tuning tool, and thats it.

Wierd thing is that we have had same quads on Jansens,Rossier,Steel city and Mikes Cycle and they all are well within 1hp of one another.You do need to pay attention to correction factor and smoothing.Almost all people who post charts post with STD correction and 0 smoothing.If posted in SAE like we did earlier it will be less and if posted in DIN it will be more.Higher smoothing the lower the number also.All things to watch for when comparing dyno charts.
