if i can find a turbo for a decent price ima pick up a clone motor and defenitly do this! i have access to a CNC machine and CAD software so making some flanges shouldnt be a problem.

what's he using for an oil pump though? evac pump. and what kind of boost is he making? 2-4 psi

 

[bajagokart]

holy frick that thing is WICKED!!!!

huh? you answered your own questions


but yeah he is now using a actual oil pump+evac pump, and once the motor is built he will run higher PSI

 

[bajagokart]

that guy must be a fricken genius lol i would have no idea hwo to do that lol

 

[jmadden91]

??? Have you guys not seen lemegacool's Turbo'd Shopping Kart?

Granted, it doesnt have a bloody ECU hahah thats awesome

 

[Jblankster]

^^ i dont see a turbo?

edit: went to the last page and saw. reading now.

Wild- Now if only I had that much money and free time...

 

[mike75925]

i asked the questions, then went and saw the video, decided to post the answers in my post through edit. i'm thinking he should keep his primary exhaust pipe small to get the speed out of the gases. on the bikes (yamaha turbo) they had a collector that ran 4 into 2, into 1. all to get an even pulse on the turbo. it ran 12psi? and you could add a washer to the end of the wastegate pipe to increase the boost pressure. you may be able to get more by running a d-port to the mouth of the turbo. by closing down the exit side of the pipe, you would increase pressure and funnel the 'fuel' right to the proper side of the turbine wheel.

genius much?

 

[freakboy]

i wonder how much power its putting out.... runs pretty smooth...

 

[bajagokart]

12 psi is a frick load for a small engine like that

 

[lemegacool]

lol mine was waaaaaay less complicated but it lasted less long

i'm in the hunt for another turbo to run a blow through setup... with boost activated fuel pump and sealed carb and intercooler and bov lol

 

[Jblankster]

^ i was thinking last night, with a BOV it should help prevent blown turbo seals.

 

[Jblankster]

or i might turbo a diesel motor. stronger, and bigger etc. http://www.youtube.com/watch?v=RH3-QBU-gY8


and SOUNDS LIKE A DIESEL!!!

 

[mike75925]

blown turbo seals? the turbos i've seen have no seals as such. when they spin, they create their own seals via air. i thought it was kinda crazy, but then for the longest time, i couldn't understand how a jet engine worked

 

[Jblankster]

read lemegacool's thread he blew his seals which caused oil starvation which killed his turbo

Oil seals, ever hear of a runaway diesel?

 

[mike75925]

nope, never heard of that. what exactly does that mean? what was lemega's turbo rated for though? the one on the bike was rated for 240krpm.

read lemegacool's thread he blew his seals which caused oil starvation which killed his turbo

actually it was the vacuum pumping the oil out of the cartidge, plus the fact that my oil wasnt cooled or filtered D'OH!!!!!!

the acual seals are fine in my turbo, only the journal bearings and my comp wheel sustained damage...

yes there is either a carbon or dynamic seal on the compressor end and a piston ring seal on the turbine side
