Here is what we have found on our 2009 and 2010 testing. We setup cones and did some timed runs and checked top speeds. We did three runs for each test then took the average. All speeds are speedo speeds. Here is what we found today.
STOCK 2010 Teryx
51 MPH top speed ......... 7200 RPM
200ft time - 37 MPH @ 6.10 sec
400ft times - 45 MPH @ 9.62 sec
700ft times - 49 MPH @ 14.39 sec
added MSD on advance map 3 and fuel map 4
58 MPH top speed ....... 8300 RPM
200ft time - 38 MPH @ 6.02 sec
400ft times - 46 MPH @ 9.51 sec
700ft times - 51 MPH @ 14.20 sec
added DASARACING over drive clutch cover
60 MPH ........ 7400 RPM ....... all 200,400 and 700 ft times were the same as above.
ADDED .... Dasaracing pipes and Dasa fuel curve .... UPDATED
65 MPH top speed .......
200ft time - 5.43
400ft times - 48 MPH @ 8.67 se.
700ft times - 55 MPH @ 12.74 sec.
Here is the big issue ....... YES ... the over drive cover only gained 2mph on top end ...... BUT ... it dropped the max RPM by 1000 and still went faster. Without the overdrive cover the stock car is REVING OUT BIG TIME at 58MPH and at 8300 RPM. With the over drive cover installed it is crusing at 60 and not reving out hard at 7400 RPM. You wont want to drive your teryx around at 58MPH spinning 8300 RPM for very long. By adding the over drive cover you will gain 2 MPH and drop the RPM's down to 7400. Once we add pipes, intake and throttle bodies this car will rev out higher then the 7400 and gain some more top speed. Our 840's with the same setups are hitting 70+ MPH. More testing to come very soon. ......... all other clutch parts were STOCK
