lool ok ok :D so it's like i said, this car has originally a system that manage de pressure sent by the supercharger, it has a ECU with the map sensor that read's pressure's till 1 Bar (is not much xD), it has a wide band O2 sensor, and a CO sensor in the intake...it's a little old but it works xD.. |
What he means is he has the Polo G40 system. It originally meant to work with the VW G-lader, but he's ditched it in favour of the turbo :)

in this case nop, the only thing that need's to be changed is the ECU Eprom file..to only "spray up fuel" até the time that the turbo start's to spool... The original file is always pumping xD lol |
looks good
|
thanks :P
|
need test data
|
something diffferent
|
later i will upload some vids...
|
i've seen a few G40s changed to turbo. There was actually twin turbo G40 near my place. Anyway, great job!

wow twin turbo i've never seen...that must be excelente in this engine.. :D thanks for the comment, could you put some links to that G40 with the twin turbo? |
here's some vid's, not with the hight quality because it's hard to film and drive xD
YouTube - Polo G40 turbo YouTube - Cup vs Polo G40 vs outros |
in for updates
|
awsome!

well here it's something new..
Wrap my downpipe! http://img136.imageshack.us/img136/1462/imagem232.jpg Oil temperature and turbo gauge PS - I have a question, what are the opinions about wrap the turbo?? anybody in here have try that? http://img136.imageshack.us/img136/2995/imagem108.jpg |

Wrap my downpipe!.......................... what are the opinions about wrap the turbo?? anybody in here have try that?............ Yes: To reduce heat up time and keep exhaust energy high. Reduce turbo 'lag'. No: Will cause the turbo to have shorter life...more heat to oil...more heat to coolant....increased fastener failure due to thermal overloading.......no measurable increase in power...total waste of time. For a street car you just need a heat shield to stop radiating heat . Wrapping has not proved to be effective unless your running Le Mans. WARNING: Wrap around the turbo/headers/down pipe will be a fire hazard if the wrap becomes soaked in oil. It WILL catch fire...ask me how I know. |

thanks for the advice!! The Asian vehicle manufactures clad the exhaust pipes and build a radiant shield around the turbo. If fitted tight enough this is best for turbo and will not catch fire. The down pipes are usually clad with steel or aluminum cladding crimped around the pipes. I noticed early Honda's had an asbestos type of packing inside the cladding. Have seen this insulation material burst into flames too on dyno pulls. It only needs a little oil to initiate a fire when the pipe it is next to reaches oil's flash point. If your able to fabricate a shield this will help especially if the shield hides the turbo from direct cold ram air. Don't use stainless steel as this is too hard to fabricate and cut. Make sure the shield has good support as vibration will make shield mount areas crack. One last thing...When a metal is heated to yellow heat or beyond..around 1200F to 1500F... and is wrapped, this cooks the metal and it erodes from the inside .

that link is awesome... according to their little graphs, if I use ceramic coating, my header will actually gain material!!! Awesome! It's like a little custom stainless steel generator. I'll be RICH!!!

And here I thought steel was mined, not grown. Learn something new every day. Can you get government subsidies for a steel farm? Cuz I will build a whole fleet of race cars with ceramic coated headers if that's the case.
