I am technically zero here... this just reminded me of my beloved classic fiero in stock form which i have not used for months now.

All i knew about it was, the engine was a gem. When tvs made this fiero, they gave a ultra conservative package around that engine. Only recently under apache, rtr disguise other parts of the bike are getting up to date with that engine.

Venu, what you have managed to do by posting this pic is... i am getting some ideas now. I will pm you...

  • Is that a flex pipe from car exhaust you are using.
  • Dosent Hydraulic drive system have a lot of losses. Can it handle 7000 rpm?
If you leave the carb in its original postion it gets complicated.You will need a fuel pump,which will have to pressurise the fuel as a function of the boost pressure.We checked the boost today and it was 7psi(about 0.5 bars),perfect for a stock engine.So no need to reduce compression.Mine modded to a 200 cc already though.

Good work there man. Just a couple of questions.....what are you doing with the timing, and did you fabricate the supercharger or is it off of something?

Hi Venu,

The stuff looks impressive, but I'm a bit of a layman, and I'm sure so are many of the others looking at this thread.

What exactly has been done?
What are the results? increase in power? Obviously but by how much?
Increase in the acceleration? By how much?

what does supercharging include?

All basic questions! but kindly bear with me, as the supercharger looks exciting and a DIY always holds great reverence in T-BHP!

Nice, is it machined from billet. Basically looks like a large hydraulic gear pump. Have you seen the Eaton blower with twisted lobes? Whats the difference between the two.

Venugopal, did you design the whole thing on CAD yourself and then CNC it out?
How much did you pay for the CNC job if i may ask, or do you have access to a machine?

What kind of ratio does the super spin w.r.t the engine / what is its typical operating rpm?
Have you used bearings? or are the shafts lubricated? how?
What kind of clearances have you achieved?
Does it get warm/hot when run?

Can we have some more pictures!!
