predator 670 vs vc460
I would really like to use the the predator 670, but whats the point when the vc460 creates the power it creates ungoverned.
Are there any performance parts for the 670? Which has the most torque? Which will spin the tires |

Re: predator 670 vs vc460
Even without the governor removed the Predator 670 will make more torque because it is a V-twin. The only problem with the Predator is that it needs a rev kit. They make one for the Honda GX 630/670 but it hasn't been determined if it will fit the Predator......technically it should but I've never seen anyone do it. I think once people start modding this engine it will make some serious power.
The VC 460 is a nice solid motor. It's a nice step up over stock. |

The predator looks exactly like the Lifan engine... surely there's parts out there for it

Re: predator 670 vs vc460
that 460 makes some good power ive seen a few mini bike engines on oldminibikes.com dyno on a engine dyno as high as 40-50hp look up user (pro69nova) has prolly one of the highest hp's ive seeen and that was out of the 390 block.. basically it all boils down to how much are you willing to spend (how deep are your pockets!)lol . http://www.mikeclementsracing.com/openspage.html has one that makes 52hp-60hp for $5,0000. like i said the opinions are endless.. will say yes tq maybe a tad bit better with the "big block" but have you seen the BB vs vegas carts 440cc on stock gc tires it litterally puts 5-8 carts on the BB. and the BB in the video is lifted with bigger tires and all that and all that so it should be able to hit a higher top speed with the larger tires . this should awnser you question https://www.youtube.com/watch?v=EB9B5qbodJk
and heres a 627 vanny BB with a good deal of mods getting smoked http://www.buggiesgonewild.com/big-b...ml#post1145867 neither BB's ever pull them off the line and up top they get left no top end even with the rev kit.. |

Re: predator 670 vs vc460
The V-twins have more displacement. Period.
Aftermarket support for mild-mod twins is lacking, but putting the same level of parts on both, will maintain the 1.5 times or so more overall, matching displacement. The 750cc Kohler is likely the platform most supported, and makes the highest specific output, in mod form. I never tire of this one: https://www.youtube.com/watch?v=TC8yYTXoZm4 |

Re: predator 670 vs vc460
Depends on your budget really, for the money, our 460cc engine is unbeatable.
It makes 21.4hp and over 31ftlbs of torque to the wheels!..in stock form. (Add 25% for Engine numbers) Our engine kit in a completely stock Yamaha G16 achieves 38-43mph on factory 18" tires. Can you make more power than the 460? Of course, but Ive yet to see a NEW engine that can for the money. Then again, the 460 has a custom ground cam, higher compression, billet rotating assembly, etc direct from us. |

Re: predator 670 vs vc460
Pretty solid torque numbers for a lightly modded one lunger! does anyone have wheel dyno sheets from a vanguard in comparable horsepower range?

Re: predator 670 vs vc460
Lightly modded? I'm quite sure this test was done on their top of the line clone. It's still impressive for a single cylinder engine.

Re: predator 670 vs vc460
lightly modded referring to a go kart motor as I've seen a go kart on alky 440 pulling 30hp plus on a wheel dyno. A " stock rx440" would be with stock tiny carb and stock head deck, correct me if I'm wrong geoff. I would think I higher compression (.0100 cut head) 460 with 32mm carb and larger timing key could do plenty more. No mention of which rockers used either. Some 1.3:1 champion rockers or 1.2:1 shaft mount rockers could push it to 25 whp which is pretty solid.
