Hypergear Turbochargers and High flow Services Development thread

I have been thinking though. The stock turbo was set to 13/14psi but in cold weather had no trouble pushing over the boost limit though my intercooler and it's a much smaller turbo.

One thing to note on my current setup is my actuator gets it's boost feed from the cold side of the intercooler so technically the turbos wastgate should be shut tight when my boost starts to drop.

Rolls - that's why I'm here, to see what people have on their cars. I think I should actually use what ever stao has on his test car as it "should" give similar results.

[Rolls]

Yes but your new turbo is now flowing much more at that given boost pressure.

You should hook the actuator to the nipple on the compressor, why on earth are you running it from the IC?

Re using the same IC as him that is a really good idea, at least you are removing another unknown that way.

There isn't a nipple on the compressor. The fitting that used to go to the charcoal canister was the closest fitting I found.

Run it from the Plenum!

FAIL!

This will be half your issue... Run it from the compressor cover or the cooler piping BEFORE the intercooler

Correction, it's the line that used to go to the aircon compressor.

Exactly, thats how it is setup from nissan.

I can't exactly put a fitting in rubber hose . All I can do is get a fitting put in the stock turbo to intercooler pipe.

[Rolls]

that is weird that it doesn't have a nipple on the compressor housing, are you using one of HGs aftermarket housings? If so how does he set them up?

If anything though running the hose from anywhere else should cause boost spiking, not bleeding off.

I ran 20 psi rock solid running the feed from the plenum through a bleed valve to the standard 7psi rb25 actuator

[lilcrash]

Yer it's one of his housings. I never asked how he has his.

[hypergear]

Mine has a nipple that comes out of cooler piping. I also uses vacuum from the plenum, made no difference.

[lilcrash]

Ok I'm sick of playing this game now. Now it only makes 16psi and nothing has changed

[zebra]

check for leaks, (cooler piping joiners, holes in the core) exhaust manifold studs broken off etc

[hypergear]

I think its best to send it back and swap for a FNT G3, I can give you my 330rwkws nistune map, load it in and see if that changes boost and power behavior, That turbo should also suit your driving style better.

You're changing it's symptoms, that's a good thing. Just keep working through it.

[zebra]

Stao...want to give me some highflow ct12a's for evaluation purposes?

[lilcrash]

I didnt touch anything. It's just not making as much boost now
