Title: Savage Dyno Charts Post by pasimura on 05/09/15 at 14:10:24 If you have Savage dyno charts show it to us. It would be nice to compare each other's results. 8-) |

Title: Re: Savage Dyno Charts Post by Gary_in_NJ on 05/09/15 at 18:23:36 It would appear the the posted dyno is in the metric system. 66.94nm is 49.37 ft-lbs. that torque peek happens at 3500. 49 x 3500 / 5252 = 33 hp. The hp peek appears around 5750 rpm and shows 57 nm, or 42 ft-lbs. 42 x 5750 / 5252 = 46hp. Still, impressive numbers. |

Title: Re: Savage Dyno Charts Post by justin_o_guy2 on 05/09/15 at 20:24:39 I can post all kindsa Impressive BS. Until I see reason to believe that Dyno, its bs. |

Title: Re: Savage Dyno Charts Post by old.indian on 05/09/15 at 20:58:58 According to the factory specs (I found online somewhere) Power = 31 HP @5400 RPM Torque = 50 Nm (57 ft. lbs.) @ 3400 RPM 60 MPH = 3940 RPM (The last is the reason I went with a tall 140/90/15 Michelin. Which, according to the math, would reduce the RPMs @ 60 MPH to 3700.) |

Title: Re: Savage Dyno Charts Post by pasimura on 05/09/15 at 23:42:32 Hi, Some photos from the past. It was red before & changening bigger front belt pulley. Btw. Which kind of ignition coils you use? It there better coils available ? Dyna coils ? |

I've always heard/read somewhere around 25 hp/30 ft/lbs. 57 ft/lbs seems a little optimistic. Gotta link? I'd love to see a comparison on this thread from bone stock engine to a top fuel dragster! :D |

Title: Re: Savage Dyno Charts Post by Kris01 on 05/10/15 at 16:50:21 I'm curious now... According to wikipedia, it's 31 hp @ 5400, 37 lb/ft @ 3400 rpm. It must be true - I read it on the internet. ;D |

It's completely creditable. High compression over bored piston, hotter cam, ported and polished head, well jetted carb and a VERY optimistic dyno. Not all dynos are created equal, and some flat out lie...and so do their operators. The guy paid good money for a piece of paper...let him enjoy it. Decades of engine building and tuning have taught me one thing, most dyno sheets are useless. The one value they have is to determine the impacts of mods on your engine, but only as they relate to the delta on that dyno. I would be interested in seeing the pre-mod run. If there isn't one, then that dyno run is useless. |

Title: Re: Savage Dyno Charts Post by justin_o_guy2 on 05/10/15 at 20:02:27 It's not Just you or this post. I can't count the times people have popped in, got everyone trying to help them and Poof, gone. Please pardon my cynicism. |

Title: Re: Savage Dyno Charts Post by Dave on 05/11/15 at 04:07:04 Whatever the numbers are on the chart.....it is about as much as can be done to the engine. The 97mm is the largest piston/cylinder that will work, the DR650 cam is more aggressive than the available Savage grinds, the carb, porting and Raask all help. He has built an engine that is going to run very well and be much faster than the stock bike. I am sure it could pull some taller gearing to help cut down the rpm on the highways.....I see in one photo he shows the Kawasaki front pulley. If the 7,700 max rpm that is listed on the Dyno sheet is real......that would have scared me pretty good. :o And yes, it would have been nice to put a stock bike on the DYNO the same day so a comparison could have been available. I have never had anything put on a DYNO - but I have read that the numbers can vary greatly from one DYNO to another. |

Title: Re: Savage Dyno Charts Post by LANCER on 05/11/15 at 05:28:27 The numbers are entirely possible. He did all the right stuff and got the result he wanted. |

The results are very good. Do you happen to have a pre-mod dyno run? What type of dyno was used? Can you share some details on your modifications? Who did the work? Are you running a custom header pipe? |

It's 12711-12D00-000, found it from a finnish Savage forum. Here's another dyno chart, it's the same bike: https://scontent-arn2-1.xx.fbcdn.net/v/t1.0-9/13368_10153387930413606_6209952200910323785_n.jpg?_nc_cat=0&_nc_eui2=v1%3AAeGEw25I_A7Rh-2MG_rAs54kpe1GW0yxGpaRppH8TmPP2ORIpbiOGbBQ1YbMxXDBdcsX2rSjvmbssLx473ehZ4sdmMHnKRYRXDyUDymyh4wAyA&oh=f108f2d8cf61e9269a99035408c9f4c0&oe=5B38C97D |

Title: Re: Savage Dyno Charts Post by Fast 650 on 03/29/18 at 10:50:42 I noticed that torque and hp cross at 7000 rpm on that chart. Is that because of the units being metric? In SAE they should cross at 5252 rpm. |
|
Title: Re: Savage Dyno Charts Post by batman on 03/29/18 at 12:06:42 Fast650 the torque and hp still cross at 5252 although these charts don't show it because they use the same vertical scale to show both hp and Nm . If you look at the dyno posted by Pasmura on page one, you will see a flat spot for both hp and Nm at about 2000 rpm, if you slid the curve of torque down so those flats were even you would find they do cross a 5252 and would be the kind of dyno we see normally. |
|
Title: Re: Savage Dyno Charts Post by DragBikeMike on 03/29/18 at 13:34:01 The torque at 5250 rpm is 61 Nm. Simply convert Nm at 5250 to ft-lbs. It works out to 45 ft-lbs. If you check the graph you will see that 5250 rpm crosses the torque scale at the value 45. It works out perfectly. |

Title: Re: Savage Dyno Charts Post by Fast 650 on 03/29/18 at 22:52:58 I see, said the blind man. I didn't catch that when I looked. |

Title: Re: Savage Dyno Charts Post by DragBikeMike on 03/31/18 at 00:11:08 I just had my bone stock 2016 LS650 dyno tested. It should be useful as a baseline (at least for me). I hope I can attach the jpeg file of the run. In case the old man can't get the tech gizmos workin the numbers were 30.5 Hp @ 5500 rpm and 34.9 ft-lbs @ 3500 rpm. The air/fuel was actually pretty good except for about 1500 to 1800 rpm. I honestly think that area of the rev range can't be measured accurately. The carb hasn't been touched. Air/fuel was pretty much 13 to 13.8 throughout. It signs off about 5500 rpm. LMK if the jpeg attachment works. |

Title: Re: Savage Dyno Charts Post by LANCER on 03/31/18 at 02:30:10 Yep, it works. |
|
Title: Re: Savage Dyno Charts Post by badwolf on 03/31/18 at 05:17:12 Those numbers are at the rear wheel, right? Or have they been corrected to crank numbers? |
|
Title: Re: Savage Dyno Charts Post by Dave on 03/31/18 at 05:55:08 I would think the 1,500 - 1,800 rpm range is difficult for a carb to be very precise at regulating fuel flow. The pilot circuit is beginning to fade away, the needle and slide is just starting to add fuel, and the air flowing past the slide is going to be pulsing heavily....and there is so little air flow compared to the size/volume of the slide and venturi that the air velocity is going to be pretty low. |

Title: Re: Savage Dyno Charts Post by badwolf on 03/31/18 at 08:00:08 If I was going to have a ''blip'' or bad spot in the mixture, I would be very happy it was at 1500-1800 rpm range. The only times you would ride thru it would be in 1st and 2nd, and then just for a moment. I have high gearing and seldom, if ever, go over 4k, but still don't actually ride in that low rpm range. 2k to 2400 is as low as I will keep it, and then only when easy cruising in traffic. My bike seems happiest between 2500 and 3800, and with my high gearing (3400 @ 60 mph) I can live with that. |

Title: Re: Savage Dyno Charts Post by DragBikeMike on 03/31/18 at 12:17:57 Yes, measurement at rear wheel. It's right about where it should be stock according to the specs I pulled off Wikipedia. A little lower but the temp and relative humidity were very high. Especially RH. I didn't mean to say that the air/fuel ration can't be measured at 1500-1800, what I was getting at is that on the dyno, doing a 4th gear roll-on, the beast is chugging & buckin pretty bad when you first start the pull. It doesn't like accelerating in 4th from that low of an rpm. Once it got its feet on the ground it was a nice smooth pull, and the air/fuel was right where I would want it to be. Now I can start havin some fun. |

Title: Re: Savage Dyno Charts Post by batman on 04/05/18 at 03:01:45 Which cam you use be it DR650 or Lancer's stage three should depend on the type of performance you desire from your bike. Both cams have nearly the same duration , but achieve it differently. The stage three has longer overlap , the cam lobes farther apart ( termed closing the centers) and less valve lift ,peak torque occurs at a higher rpm and is flatter ,this favors higher top speed at the expense of some low and mid range performance. The DR cam has higher lift and shorter overlap (termed opening the centers)do to it's dirt bike parenthood ,and will make it's torque and hp more in the low and mid range ,at the expense of some top speed . It might be modified by the use of kawa pulleys or chain drive, I see from pic's that Pasimura has obtained a kawa front pulley already. |
