Induction for throttle bodies

[TheKeymeister]

This might sound stupid, but I'm seriously considering a TB setup with megasquirt etc

 

The thing I'm struggling with is a cold air feed to the ITBs, is it worth running a pipe from the grille/usual inlet area, or would it be far eaiser to use a bonnet scoop? If so, how would I deal with incoming rain water etc?

 

I know a bonnet scoop sounds chavvy, but it seems the most direct route to the inlet in this setup

Yes it's very worthwhile having an airbox for ITB's. It's a bit silly not to have one, but people that don't know better still do it!

 

Bonnet scoop may be difficult to implement due to aerodynamics. It may end up being a vent rather than a scoop depending on its design and pressure zones.

 

Jenvey do sell an airbox not for their ITB's but I don't think it's really big enough.

I wouldnt bother with ITB's unless you have the funds to finance it to be honest, ALL you get with them is extra throttle response.

 

I would go down the bike carb route if your on a budget. Its much cheaper, and in all reality there isnt much of a difference between torque curves on live ignition mapped indies compared to mechanical ignitioned carbs.

 

The biggest reason for the poorer plot graphs on bike carbs is that everyone goes for massive carbs, typically removed from the R1, which is no good.

... and the additional power?

Fitting indies has nothing to do with power, its all throttle

 

going forced is the perfered choice for power.

Of course it's to do with power as well.

Hang on a minute? You own numerous performance cars and think that ITBs only imrpove response and dont improve power? What an idiot.

 

turbos have their applications, and so do ITBs, hence why some performance car manufacturers use(d) them as standard, old BMW M cars for example

[Stu]

The primary benefit from port butterflies is increased throttle response (due to the proximity of the butterfly to the inlet valve) but they will give you a power increase if the original common plenum intake tract was a restriction (which is often is).

[Tez162003]

i did the Jenvey set up and got an additional 30odd bhp. how is that not a power increase, granted turbo's are far better for big power but a ITB engine is something else. always has grunt, no lag and the sound!

 

In all -TJ- you dont have a clue, go do some searching on wikipedia, then come back when you know what your on about.

itb's are fitted for the extra throttle response, not power. They do improve the power ( i never said they didnt )

 

exactly the type of responses expected from some 1990's moron ford escort owners.

Because you are unable to post anything on the internet without insulting people, i'll reply:

Are you that retarded that you can't even read/understand what you type? (perhaps you understand this style of communication)

I suggest you read the rules you so eloquently reminded me of kid,

Does he get the same treatment ? Or is it one rule for one on a £250 banger forum ?
