Please Help!!

I have a tecumseh 6.5hp on a yerf dog 2 seater. 20" rear tires and 15" in front. My setup is 60tooth and 10tooth. (still new to this,excuse my description). It does have a torque converter. What I need is some links to any parts I can buy to make it faster. You guys gave me great ideas but I dont know mechanics, so I would need step by step. For now I guess I could use your help on a better carb that would fit and an exhaust. Thanks!!

Go to a different and bigger engine. Get a 11hp honda clone off ebay. It will cost you less then trying to get hp out of your 6.5, and the 11hp will give your more torque, and this is what you are after.

 

[jayden727]

Thanks! I will look some up and see what there going for.

Something to keep in mind here is those larger engines usualy have a 1" pto shaft and your old converters driver probably wont fit...

 

[jayden727]

Yeah I was thinking, can I take it to a machine shop and reduce the shaft?

 

[anderkart]

I've never had it done but I've seen serveral guys suggest that alternative. I've also seen a few guys suggest this weakened their pto shaft and caused it to eventually break after modifying the engine to higher hp levels. I dont know who to beleve at this point but If your going to leave the engine mostly stock I think you'd probably be fine having the crank turned down.

i swapped my LARGE 22" rear tires for some off a golf cart same 4 bolt pattern REALLY helped it out... the golf cart ones were 18" and slicks


you say "faster" you want more take off or topspeed??

 

[jayden727]

I've learned with you guys you cant have both so I guess I need torque, or take off speed. Im using it for off road so I cant really use top speed unless im on the street.

 

[freakboy]

yes then gear it for torqe and then mabey do engine mods.

What if I buy an 11hp engine. Will I need a torque converter or will it haul *** with good gear setting? Just looking for the cheapest option. Tough times,sucks!!

it will haul *** with a good gearing but a torque converter will haul double ***
