Alternator Kit Install - alpost.info/mine/ZNyXr37DjpimnmQ/video
In today's video we take a Harbor Freight Predator 670cc V twin and fully build it for boost. We install performance 670 custom grind cam, billet rods, billet flywheel, billet .020 pistons, port and mill the head with copper o ring, alternator kit, roller rockers, steel pushrods, HD valve springs, billet valve cover, AMR300 supercharger, and S&S super b carb. This engine should push out around 70hp and 70ft-lbs. Stay tuned for a dyno of this engine and see it in action on our full independent suspension custom buggy!!!

About 16 links up from the bottom of the list of products is a “roots type supercharger” but that link doesn’t work. Can you point me to it? Also the link for the predator 670 is dead but I figured that 1 out

What do you do for a living, out of curiosity ? I mean it seems clear you’re into engine builds/rebuilds etc. but are you a performance shop? What do you focus on/specialize in mostly? I’m assuming it’s not predator motors but given your level of knowledge it’s clear you’re not just a lawnmower motor repair guy so I’m just curious what you generally do because I’m impressed by your knowledge and experience I guess
Fee 6 ditë më parë
Who made the supercharger ? It’s a certifugal or a positive displacement blower ? I’m looking for a company that makes small super chargers for motorcycles. Ideally small positive displacement blowers (roots etc) but worst case a turbo used in a belt driven centrifugal supercharger fashion would work too. Any suggestions? Edit: fascinating it’s a little roots type! I wonder if I could get this working on a motorcycle and how many sizes they make

Wouldn't it just be cheaper to put a GSXR engine in it and have longer life + more HP? Dropping over 2 grand into a lawnmower engine seems excessive for the output. Nice build and awesome work nonetheless.

I'm assuming you did alot of this work to get rid of the engine governor/ limiter & the oil sensor. You can get the engine, any engine to run smoother & quieter if you add in 1/4 cup of slick 50 oil additive to your normal oil AT the point of oil change, WITHOUT OVERFILLING THE OIL. Add it in 1st, then carefully top off with your normal oil without overfilling the oil OR YOU'LL blow out the engine gaskets. Then your engine should last an extra 100k-200k miles beyond normal because of reduced engine wear. If you get a 1 & 1/2 diameter PVC pipe & point it directly forward & then downward 15°(not blocked by anything) ,then run a rubber hose from it over to your air filter, intake, you'll suddenly get more than double the speed & power from the engine beyond normal. It gets better if you use a k&N air filter. Also the bolts holding the exhaust pipe onto the engine block have to be made out of case hardened galvanized steel, because of all the sudden engine power. Soft metal bolts will break in half.also you'll get more power and take it easy on the engine, if you install motorcycle expansion chamber pipes in place of the original exhaust pipes, to get rid of back pressure off the engine. Any gas octane booster additive will add more power by adding 1/4 cup/tankful. If you install headlights, tail lights, + hi beams, front & rear turning signals, & a license plate light, & brake lights+back up lights, & seat belts, a windshield + insurance, then you can get a license plate & make it Street legal, even highway legal if it can reach 65mph, but it should reach speeds up to & over 100 mph, if you install a manual motorcycle 5 speed transmission gearbox that has reverse & matches your engine with a manual clutch, if you use a manual air choke, starting the engine iñ it's mostly closed setting at start up, then open it all the way up once your driving steady, you'll get even more engine power. Good luck, put in a speedometer, like a motorcycle speedometer, with its own backlight, you can brag about your new top speeds.also you can keep track of the mileage.☺😎😇

Nice thinking about building one for my ultralight. You didn't install a stroker crank. Is there not one being manufactured yet? Would be nice since it would offer even more torque. I know they offer a stroker crank for the smaller predators. If they make one for the 670 do you have a link for it.
