bleeding, in my completely uneducated opinion, seems like a really, really bad idea.
And for a computer controlled boost, it won't work at all.

Jeff, What are is your question with that system you posted? If it will work, or something else?

A bad idea, on a car like his, yes. ItÔÇÖs too new to be f'in around with stuff like that. But I dunno, I just figured I would put it out there. The spring is safer, but like he said, it didn't work very well

I'm not 100% sure, but I think it will. The picture shows a mechanical setup but a bleed in line from the wastegate solinoid should do the same thing. It just tricks (I guess you could say) the computer. The computer is telling the actuator to open at pressure X but you have changed that so the pressure at the actuator is actually Y. This can allow you to get more boost, but the fuel will continue to go down (or stay stable) as the computer is assuming the boost is lower then it is. On a car like his with an aftermarket computer ect. ect. it might be better not to fool with that as it could be harmful to the equipment. I would say a needle valve with a REALLY SMALL bleed might help out a bit, without being too dangerous.

That's the part I was saying was a bad idea. I mean, it's all well and good to fool the computer into thinking something, it's another idea altogether to have what is basically a hole in the wastegate actuator line. I'm sure it would work fine, hell it might work fine forever.
But it might not. And if it fails, it fails with the wastegate never opening, rather than failing and opening the wastegate. That's what I don't like about bleeder systems.

VERY true. Its not a perfect system. Thats why it might not be best on a 2004 (or whatever year) WRX. A pyrometer and a wideband can help avoid massive failure though. Thats the kind of thing that causes melted pistons.

You going to stick a pyrometer "down the hole" to measure temps?
I think an EGT would be far more useful.

What kind of a knife do you use to split hairs like that, RJ?
- .RJ - 09-15-2005
Well, when I think pryometer I think tire and brake rotor temps.

And when you think of EGT....what do you think of? How do you think Exhaust Gas Temperatures are measured? With a pyrometer. (Greek: Pyro meaning fire and meter, of course meaning a measurement or measuring device as in Chronometer, Thermometer, hygrometer, etc.)
- Jeff - 09-15-2005
My EGT, is a 1600degree "Pyrometer." Says it right on the front.

Also, look real close....EGT :lol:

Just set up correspondence with a guy for a Garrett GT30R =p lol!

You are gonna need a parachute off the back of the Subie if you keep this up...
- Evan - 10-04-2005
while it may technically be splitting hairs, when racers talk about a "pyrometer" it refers to the device that takes tire temps. communication and dialog always depends on the context
