Building two turbo Bikes
Hello Everyone. I Attempted to build two Turbo charged bikes, but it wasnt a great success. I have identified the faults as well. Here's the story.
I have experience on Turbo charging FI Engines. But this was my first Carb - Turbo Engine project.
Well basically there are two ways of doing this. Blow through turbo, Draw through turbo. Generally, everyone prefers blow through turbo charging as you can go higher on boost and also have no start up issues, you can add an intercooler, and maintain a steady AFR.. and so on.
Draw through turbo was used a long time back. I chose to use this method as:
1. Its simpler to start off with
2. Engines were not built to handle higher boost (Stock P180 and Stock FZR 400 Engines)
3. No need of a fuel pump, Pitot tube Fuel Balancing system, Fuel pressure regulation, and no need to add a high pressure line to the fuel cup of th eCarb.
I almost resolved the issues on the P180 Draw through setup, and the bike eventually did I would say 25% higher on power.
The FZR however did not work out. The engine refused to rev above 7,000 and did not have good throttle response. The problem has been identified: I needed a bigger carb.
But Now I dont have the bikes any more to experiment.
Here are some pics, I'll return soon with details.
