gtb equal length

[tez n u]

Do the twin turbo legacys become equal length once both turbos are kicked in?

[DacerX]

thats a strange question

[D-Style]

What is this I dont even

[tez n u]

Made me think coz looking at how it is set up it seems like it would be closer to equal length and if you adjust the exhaust valve flap the sound changes a bit and looses its rumble.......

[Marky]

"In a way" yes - same distance up to both turbos and a balance pipe between both banks

In practise I wouldn\'t really call it that though

[tez n u]

So it isnt just me coz i swear it looses its rumble when the second turbo kicks in.

[lachlan]

It 100% loses the rumble with the ecv open . Pull that vac line off it at idle and you\'ll see .

Your observation is correct al though the terminology is open to interpretation

[D-Style]

The factory exhaust manifold is un-equal lenght......

[Marky]

Its a mirror image of itself if you look at it when its running parallel, so you could say its equal length... technically it is or isn\'t depending on if its single or twin at the time

Its just a term of phrase though its a disgusting mani when in twin anyway, both sides are pointed at the other

[xeroed]

like marky said

when running parrallel its pretty much the same on both left and right bank , just has a balance exhaust pipe in the middle , and a huge restrictor where the flapper is , that port is like only an 3/4 of an inch in diametre compared to passemger bank which is unrestricted at like an inch and a hallf

So in theory its equal , except for that restrictor on the secondry side.

[tez n u]

Ok anyone know why we have a restrictor on the secondary turbo?

[DacerX]

so you dont release all that power on the world

[tez n u]

Im thinking that its to prevent overboost but not 100percent sure

;D

[Marky]

Its not a restrictor as such - its just "thats the size of that hole and it is a restriction"

Once I get hold of a second one I\'ll port it out and see what if any difference there is

i feel this could happen

[tez n u]

On a side note Steve Murch did the anti surge compressor mod on my gt35r and its looking very nice....very happy with his work...hopefully i get no more surging now ;D

[Pappu1]

nice

[tez n u]

thanks bro ;D had very bad surge before....boost came in too early even with .82ar

[Marky]

They get an awesome whistle with that done as well aye?

Sweet

[tez n u]

Yup whistle would be a bonus 8)

[xeroed]

Well anything restricting the flow of anything is considered a restrictor,

with the restrictor we have in out TT systems, i got no real evidence to say i know what\'ll happen with it enlargened.

depending on if ur running it 2 stage or parrallel

With it in 2 stage it could possibly reduce Pressure on primary and convert it into More Secondry/Top end Power

Could Also reduce VOD period Because of the Extra Gasses Spooling up the Secondry during switch over

With it in Parrallel , i get best response sitting on 4k Rpm/ 4 Gear , it could possibly reduce this to get best response to about 3500rpm . But It could also increase but give more Top End

Maybe overall Itll Just give More top End say 5600rpm Upwards
