Boost Spiking Question

[Usual Suspect]

hey fellas.

first of all, i'm doing a uni project where we're looking at puting a turbo on a yamaha r6 engine.

problem is we have to run a 20mm restrictor on the intake. the restrictor limits the air flow to around 97hp or 73kW.

the engine on its own is able to make that power close to red line (13800ish), but we're looking at trying to get the mid range (8800ish) torque/power up close to this level.

i've estimated that the required boost will need to be about 5-8psi for mid range, and close to zero for top end.

the intake pressure is about -7psi between the restrictor and where the turbo would go.

is it safe/smart/worth doing to put a turbo on it.

any comments welcome

cheers, trent

quad throttle bodies, inline 4, injected, i say go for it

garrett made a bolt on turbo kit for the hiyabusa

it used to be on turbobygarrett.com but its not anymore

see if you can find it in google. had some useful info on bike turbocharging

yeah a turbo busa would by nice...

the engine is actully in a open wheel cart and the rules say it can only have the one throttle body, which has to be infront of the restrictor

its just you can only suck 73kw of air through a 20mm hole. (the engine is about 60ish at the moment)

oh and its got a motec in it.
