turbo briggs flat head pocket bike, custom build

[dan]

hi all this is just pen and paper at the moment, but the plan is to create a turbo briggs weapon. its only small but the custom built frame will host a small flat head briggs with a custom turbo kit for it. im hoping to build a 2 speed GB for it, if any one nows a simple compact unit i can have a crack at build i would be very great full if they can share there ideas. it will run a fair bit of pit bike parts, forks, wheels, brakes, shock etc. here are the parts im looking at cheap but look the goods, http://cgi.ebay.com.au/ws/eBayISAPI...0&ssPageName=ADME:X:AAQ:AU:1123#ht_1244wt_794 , http://cgi.ebay.com.au/ws/eBayISAPI...4&ssPageName=ADME:X:AAQ:AU:1123#ht_1200wt_794 , http://cgi.ebay.com.au/BILLET-ALLOY...orcycle_Parts_Accessories&hash=item19b58b4ce5

heres the frame it will all be bolted to,

heres with the the prototype body on it and engine, will be a naked bike

thanks all feed backs well come, Dan

Why dont you buy a 125cc pit bike (about 500 or less second hand) and then modify the body and get new wheels. A briggs is slow, a pit bike engine has lots of grunt.

lol briggs is slow lol, not just any brigs tho turboed and modified, reason i dont want to buy a pit bike is cause there crap and i want to build my own, i do have a pit bike engine i can get my hands on tho do uses seriously think i should run that rather my worded briggs?
i would turbo both so tell me what u think i like the sounds of a pit bike engine now lol its got the tranny and clutch, hmmm turbo 125

What kind of turbo will you use?

Thanks

Hayden

 

[dan]

T25 will be to big.

Is your Briggs a flathead or an OHV?

Pit bike engine is about a million times better than the Briggs, pretty much indestructible too.

Thanks

briggs is a flatty, and only reason i say t25 is because i have one in my shed, i was looking for a smaller one tho

You'll need one the size of your hand to get any amount of boost.

probably even smaller...

A turbo on a flatty is almost pointless. The valves will float around 5500 rpm and the motor will require a good bit of expensive parts to toughen. The pit bike motor will have more hp, torque, and a fully functioning gearbox intact. It will redline between 8000-10000 rpm and give much better performance. There is a kart on here, a shopping cart, with a turbo and I believe he has gained a max of 8 pounds of boost. It is on a highly modified gx200.

cheers, i have a pit bike engine im gonna use

You don't have a link to that do u? I would love to see it and its mods

Just search turbo shopping kart in the search bar above.

yeh turbo'ing any small engine is pretty pointless. Pit bike engine ftw!

 

[dan]

yeh turbo'ing any small engine is pretty pointless. Pit bike engine ftw!

pit bike engine plus turbo

 

[dan]

another idea i thought of is building a supercharger out of the compressor side of the turbo, that way i can run my t25 that i all ready have. would be like a centrifugal supercharger

 

[Eric492]

that means making gears, seals and getting the compressor wheel to spin more then 100k rpms which will cost $$$$ best chan is finding a turbo off a smart car or a gt12 on ebay

pit bikes arent crap. someone in my neighborhood rides around probably 50mph going all day long. nice sounding motor.

you might have a hard time making a frame better than a honda pit bike or something, but better than a copy.

you should make it real solid.
