16hp Briggs

[ZShanley]

So i am new to this stuff. i am currently attending SUNY Oswego and i am in a transportation class where we r rebuilding engines. I have a 16 hp Briggs opposed twin cylinder 656cc. I dont have any pics of it on my computer yet but it currently isnt working and was wondering how it would fair on a go kart after the rebuild.

Thanks,
Zach

Pretty good dude I have a 725cc 25hp kohler building up that's serious power for a gokart

twins for karts work good, i have an 18, and freak has a 20, and now you two with ur twins

We got our own twin gang goin on dont forget ray has that 18 on his bike of badness!

I got an 18 twin that should be going in my racing mower in progress at some point, and a horizontal 16 twin in my riding mower that i use to grass board and whatnot.

Oh and my kart has a 400cc inline twin engine, 36hp stock.

I had a vanguard 18.. didnt care for it maybe mine needed WORK

my 6.5 clone would run a circle around it..

One of are twins are looking to get turbocharged soon

I'm also running a parallel twin (500cc, 47hp). The sound is awesome!

nice, the twin gang is growing......

 

[ZShanley]

well this is good news to my ears. my build probably isnt going to start till the summer unfortunately. i am gonna have to find a frame cause i dont know how to weld so that is next on my list of things to do

*Suggestion*

We should make a performance guide for our bigger engines; What do you guys think?

 

[freakboy]

Sure we could.

 

[Rotore]

could be useful for us?

 

[BriggsTwins]

definetly,
twins are tough engines,

 

[Rotore]

where should we start?

 

[freakboy]

I could do something about them like pros and cons. then we can add to the thread. Ill have to do it tonight cause im on my lunch break here and i gotta get back to work soon.

lets start with RPM limits!!!!

4000 is the TOP!
they could use better valve springs
internals are strong as is,
watch your head gaskets as they tend to blow under heavy load/age
they are strong and even governed at 3200 kill anything else.
keep the tin and shrouding on it to keep the block cool
they love to run, but with one goofed spark plug it will run like hell
carb adjustments are key! one carb feeding to jugs is sensetive, running lean can be risky

lol awsome i'll look up a couple things on hey mow and some other sites for it!

Quick question though lol can my 25hp push a 4:1 gear ratio on a 15 inch tire

 

[BriggsTwins]

i think so, id have to do math and my brain dont work right now

11,000 rpm for this twin apparently with stronger valve springs you can get it to 13k rpm, but power drops off after about 9,500 so I don't see the point. Also my tacho only goes to 10,000...
