Re: bored throttle body results

throttle body bore results
OK guys here's what I have done I ran time tests on the rhino before replacing the throttle body and after installing the bored throttle body
here's some info on the test...air temp 74degrees 0 wind speed quarter mile pass 9 psi in tires on black top two people in rhino approx weight 500 lbs I have done six passes to get a average time my rhino has muzzy exhaust raptor stage 2 cam mad box fix powersports sheave terracross 25" tires full windshield roof and spare tire mounted to cage

before throttle body bore
0 to 40 0 to 60 mph
1 6.44 21.98 58
2 6.39 21.87 58
3 6.40 21.92 58
4 6.60 22.19 58
5 6.37 21.84 58
6 6.48 22.05 58

after throttle body bore
0 to 40 0 to 60 mph
1 5.10 20.48 61
2 5.06 20.44 61
3 4.99 20.36 61
4 5.03 20.42 61
5 5.19 20.50 61
6 4.96 20.33 61

i know some don't believe in time tests but that all i have to go by.......
if you look at the numbers you can see i picked up over 1 full second in the 0 to 40 time but i killed the 0 to 60 time because the place i ran my time has a uphill climb at the end.. Kenny believes you can get 2 to 4 more hp with just this mod... for less then $200.00 this is one of the best mods i have done..
i want to thank Kenny at kds racing for the great job on the throttle body and all the help if you need horse power Kenny's the man!!!

Re: bored throttle body results

dbl check the throttle positioning sensor on the TB.  I have a raptor 700 with a 3mil bore on it and the dyno tech told me that they mark the sensor and remove it when the bore it.  then they try to put it back in the same spot but it is never the same.  Give it a try.
