ok so.... (wastegate q)

[Pappu1]

not for me but my mate finz ...

he has a 1995 bg5 gt twin turbo

does anyone know where an external gets welded to the extractors on the TT?

i wud think on the secondary side... anyone got pics or info on how?

[Koom]

Just take the downpipe off the secondary turbo. Does exactly the same thing.

hahhaha that be the one!!

na bro its been his dream to put the external on his BG lol... wants it purely for the soung rather than performance..

but yea if anyone has a pic of description of how to fit on the bg tt GT?

i have seen a white GTB in manukau area WGating it hard hahaha...

serial? leave one not plumbed in and wait for it to come on boost - tractor noises here we come.

even plumbed i notice a slight change in note from mine.

yea like koom said, cut/disconnect the 2nd down pipe and block off the other end.

When 2ndry turbo hits its just like an external?

On BG's which turbo(s) have the waste gate(s)?

i mean a plumbed in one, talking legal here, not a boyracers pos job.

interesting to know a your plumbed in one made a slight change. didn't think there would be anything in it.

the only change is when the WG opens. This pay be because the WG re -enters the Downpipe right at the top, behind the firewall so i can hear it (as apposed to down near the gearbox mounts.

my exhaust is not overly restrictive of noise (read 106db at 3k rpm) so its not muffing anything thus i think the noise variation is easy to pick up.

[pl0x]

Yea i reckon externals sound slightly different to internals on boost (when plumbed in).

But hard to compare unless you have gone from internal - external plumbed in on the same (in which case your problem doing a whole lot of other things, twisted turbos etc also possibly changing the sound slightly)

[Guest S T E Y E]

ive seen a twin turbo with twin external wastegates...one for each turbo and the butterfly valve in the up pipe removed i beleave

[WRXER]

Plumbed in mine made no change in exhaust note, as said above depending on setup it can vary.

Externals have there place in the scheme of things and people can do whatever they want, but to say an internal gate can't control boost on a street car is silly.

Thats a stock turbo and the stock boost control solenoid.

Totally agree. The factory solenoid is only as good as the information it gets from the ecu. If you get a big chunky 3" exhaust and don't reflash then you have to expect there will be some spikes and creeping (shit in; shit out). If you want an EWG for the noise then sweet, but i'd rather spend the money on a decent tune and get a much better overall result (good shit in; good shit out).
