A basic doubt.... just wondering if any1 can help. Is it possible 2 extract 100+ bhp from a zen engine.... 'coz a Yamaha R1 has a 1000cc engine too which produces 150bhp, which is titanic compared to the mere 60 produced by Zen. Can u modify it to the extent of getting such power... wht wud go into such a project?

I remember watching on T.V., a few automobile college students fitting an esteem engine on bike. With some mods, one can definitely try something close to 100 bhp. As for the zen......I have doubts

Hey dustDevil,

Here is a link for the Photo Report of a Bike with an 800 Engine.
In this thread u will find a bike with 1.3L esteem engine also.
Check It out..

Cheers,

The engines are completely different, you can expect to spend a bombshell if you are looking to go 100 horses naturally aspirated.

Yes Psycho is right, just being same cc doesnt mean they can be tuned to produce similar Power the best example would be Busa & Swift both use 1300 c engine but see the power difference. One of the main reasons being the RPM at which the Power is produced, the bike engines produce such high power at a very high rpm which would not be practical for a car, Similary a car kind of engine for a bike would be very high on torque(since more power at lower rpm)

yeah

now no need to get into first gear at the signals just slam in 2nd and keep ur direction straight and u have a fantastic wheel spin. lots of torque low down.
no need to have busa like power but u could now cruise all day at 130kmph good for the bullet die hard cruiser image types.
btw u need to source a nice gearbox atleast 6 speed and the one in sight to me which should match i feel is the RD.
cheers to ur project if u plan to do it but remember it wont be street legal so backyard rides will be there.

do a comparision between the torque figures for the r1 engine and the zen engine, the diff will be obvious
