The great venu sir!!!

Cheers for the project.

Guess the mods here dont know all about you otherwise they would have not shown you as newbie.

Guys the number of posts dont matter to this person. He is the pied piper for two wheeler engines.

Well, everyone started as a newbie at some point of time, including the mods

I'm sure "EH" will be past the newbie status soon enough, and i am sure a lot of people are looking forward to seeing more posts from him.

I'll have a Happy Meal please, and Supercharge it!

I dont know who EH is, but it must take some serious knowledge and skill to do that!!! Back in college days, a friend of ours decided he wanted a project vehicle for supercharging and blew up his Avanti Garelli (!!!!!!!!) in the process.

Lead us on to greater things, venugopal - and WELCOME to Team BHP.

Like Shankar says, this opens up some really interesting properties. And I'm sure Shankar is a more than willing bakra.

plugged a few leaks and the boost went up,check the video.

YouTube - super charged fiero

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!!

yes designed the lobes myself,it is billet machined.It was done with a lot of help from my good friend srinivas,and a book (maximum boost ,corky bell).it is coupled with 1:1 ratio with the drive from the magnet locking nut.The bearings are lubricated for life and designed for 16000 rpm.Initially the plan was 0.05 mm clearence,but because of a machining error it is 0.15 mm now.Roots is notorious for heating up the air.Its thermodynamic efficiency is 55%.so this is one off.Have a screw type design ready to be mounted in place of the air box.It still has carburettion issues.

This is roots type and sort of inefficient.I needed it to get data for future designs.

It is close to 2 years since i joined up,but it does not matter if i am tagged a newbie or other wise.Been active on xbhp and RDD.SOme of my earlier projects were
1)4 valves on a fiero
2)Modded a fiero to v-twin engine
3)Made a stock trim fiero 200 clocking 144kph on the speed gun
All with the help of my friend srinivas.

Thanks for the replies.
Another newbie Q from me - would it be possible to retain the housing, shafts etc and just replace the roots rotors with the screw type rotors ?

What a super book! I remember seeing it in a bookstore 5years back and i wrote down the ISBN thinking that someday i will use this book.

only the rotors are helical in a screw type. The inlet and outlets are located differently.And involves quite some mods,to match.

nice work, when are you going into production?

[rrnsss]

phenomenal venugopal. Very nicely done. By the way what is the twin cylinder BUSA is talking about ? can you post some pictures of that ?

That and the only one v-twin(fiero) engine built in india ,was made by me and my pal srinivas.why it is gone into the Limca book of records as India's first .There are lot of pics on xbhp,here is the on team-bhp,
