Gtr, Cho Cho Train

[Adriano]

I would try the stock bov's if you have them, they hold more than 30 psi without drama

hey there,

i have a LINK G4

took it back to my tuner (6 hr drive there, fly back, then fly back up, drive back etc etc) he is considered one, or the best tuner's in the south island (NZ) and told him to retune it, but he still could'nt get rid of it. i told him about going back to original BOV's, or put in a softer spring etc, but he said it would'nt hold at high boost (im running 19.5lbs @ 345AWKW)

i have had so many people tell me what to do, but it's kind of hard to tell someone who's job is it to tune cars to do this-that-and the other, i dont want to offend him aye.

well might try the cold air box theory...

cheers robbie

yeah, it is hard to tell a guy who does cars for a living what to do. many of them look at customers as retards with wallets and wont take kindly to some advice you got off some kids off the internet.

BUT, i can tell you as well that for certain standard GTR BOVS that are in working order will EASILY hold 19pound and like andriano said they can hold a shitload more than that. I would be comfortable running them at up to 25 psi on small ish turbos. obviously it's not just a matter of pressure as a T51R at 25psi will need a lot more air bypassed than a pair of N1s at 25psi, but as far as just holding against the boost then it doesn't matter, pressure is pressure. bypassing/flowing enough is another thing, but the twin GTR bovs will flow a fair enough for most. failing that the big daddy trust Type R is hard to go past.

What ECU are you running?

When I put my -5s in I had the choo choo train badly. However, when I got my Vipec ECU tuned, the choo choo train is gone. It has never returned so it can be tuned out with the right ECU and tuner. And yes, I have FULL HKS hard pipe kit.

yes mine used to choof with HKS 2530's...once tuned never choofed again.

i dont give a rats arse what anybody says...it can be tuned out...mine had dual atmo BOV's and Z32 AFM's.

The only way we got my GT-RS' from choofing was to use a balance pipe manifold.
