Throttle body pics

[Lunner]

Can people post any pics of individual throttle bodies they cn find, listing which car they come off, preferably renaults, either the end the air ductng goes onoty, or preferably the end that mates wiht the inlet fanifold

[Fred]

eh???

[Craig]

iv got a 19 16v TB somewhere knocking about!!

[Lunner]

sorry fred....TB = throttle body

I'm trying to find a bigger throttle body that will fit onto the RSi fanifold

[Fred]

yeah i know TB = throttle body

but why??

did you know a 43mm TB can flow enough for 300bhp??? (N/A)

[Lunner]

I was under the impression a bigger TB woudl give more power, i seem to remember Y0z telling me, before he blew up his car that one of the options other then 4 individual bodies was to get one larger one

[Fred]

we tested one, but made sod all difference

what you want to focus on is the sucking force, and the speed and route of the air entering the engine

you basically want a large surface area filter, reducing down to a small surface area before the TB inlet, this will help speed up the velocity of the air

i think LOL!!!

i dunno, i just bodge stuff and it works

we applied a similar theory to our 182, and had some wicked results


basically we use a 64mm TB with a 100mm trumpet

then attached to that is a 100mm reducer silicon pipe (reduces down to 70mm, over approx 500mm)

then a viper sits on the end, with a feed straight from the fog light

[Lunner]

Sweet, so reduce the pipe before the TB :D

[Fred]

it works well on the F4R

but you can't just reduce the pipe, you need a trumpet on the TB to "channel" the air into it, otherwise you'll have loads on nasty steps which causes turbulance

imagine air entering your engine is water, think how its going to flow etc etc

[Fred]

so imagine

air filter with 70mm attachment

70mm pipe increasing to 100mm over say 500mm

100mm trumpet reducing to 64mm

How about gas flowing the throttle body and butterfly spindle (or maybe getting a slimmer one)? Would that make much difference?

[Lunner]

Gotcha!

Might have to start modding then

[Fred]

TBH Zollo, no

matching the TB to the inlet would help

[Zollo]

Fair enough, didn't think the gains would be all that great. Just seen it done on other cars and thought it would make Lunner happy tweaking something else!

[Lunner]

LOL, what you trying to say :roll:

I have a complete top end sat in my garage, so i'm happy to do almost anything to it
