e16se throttle question

[mowgli]

on the throttle butterfly, there is a strange piece of ally... it looks like a bit of terrys chocolate orange.

1. what does it do?
2. is it worth removing?
3. how would you fill the screw holes in?

[Andy]

Its like an xe one,where folk remove cos they think it restricts.They fill the holes with rivets,whether or not its beneficial is another story.........

[General Baxter]

ask mincer mike, he done something lol

[mowgli]

well, when you fully open the throttle, it takes up 10-15% of the available area,, i have a spare & am prepared to mess with it

[Edd]

Think Craig removed it after he had it turbo converted at Courtenay, noticed some difference iirc

[Will F]

Its to do with the how the air enters the inlet... leave it on

Wont make any difference to performance - would probably hinder tbh

i removed one by using a 2l v butterfly it was i think, more people use liquid metal or something. i saw now ill effects and with all the other tweeks appeared to have a very responsive engine

[mowgli]

so why have i never seen one on anything else???

do you think it was designed to restrict it from a design for a bigger engine size??

i'll try it & report back.

[burgo]

as will said it was never meant as a restriction, was designed to control the airflow for some reason or another

Mowgli ive done this on my XE i replaced the butterfly with one from a later one that had no segment on it. I noticed a good midrange power gain i was told they put them on to make midrange driving better if that makes sence.

[mowgli]

it won't help with any form of part throttle opening, as it is more of a restriction......

and the afm hole is so tiny that it appears to be a worse restriction...

i'm looking for a 18se afm/ecu at the moment as they were the 115hp 1800 8v & on almost identical injection to the e16se.. so i can check the afm size.
