bleed valve without boost guage

[rob77]

Yeah runs real rich you can see the AFR dropping off below 10.5 Hmmm, very interesting power, thats damn good. I would like to see the boost, when I drop into SST next I might ask steve what boost the car was making. Well, it all depends on how much power you want to make. If you think the extra 30-40hp will satisfy you then for the money spent on the safc and bleed valve you cant go wrong. If you want more power, ie: going to run a bigger turbo. I'd buy an aftermarket ecu that has some sort of boost control built in, like the powerfc or the wolf3d, rather than buy a bleeder and safc2. The best we have seen on a r33 gtst with a jap remapped ecu was mrgtst with around 285hp. Basically all he had was a HKS fmic, apexi avcr with the boost up around 12psi. Also keep in mind if you want to run a bigger turbo you will also need a fmic, if you are staying with the stock dont bother with a fmic, just back off on really hot days when you hear the engine pinging or if you do any track work.

rob77. The boost peaked at 9.2 PSI on the dyno (remember looking at dyno machine). This increase was just after i got my exhaust done. Does this seem right for hp put out. Have i got some sort of aftermarket hidden something? Hope so

[rob77]

*shrug* maybe some aftermarket cams or a HKS/aftermarket turbo perhaps. But 230hp on the same dyno I was making 245hp with an ebc set to 12psi and you only had 9psi doesnt seem right must be something in there, but the car is definately running very rich and the safc2 will sort that out.

I have a cheap boost gauge and dont trust it as far as I can throw it. I turned my bleed valve up 2 turns from standard which should be 9 psi by the bleed valve manafacturers specs but the guage says around 10-12 and gets huge spikes up to 14. my next investment is a descent gauge to make sure it is the gauge as said further up, it could be the bleed vavle.

R31Heaven, why dont you just borrow one to test it with, saves you paying for another one if the results are the same!!

As with the Bleeders, i have the GFB bleed valve and have only had one problem! no spikes or anything, just once after a track day, somehow it set itself up to 16psi, and only took me one look at the boost guage to see why the car was jerking and spluttering like crazy on full boost! the stock guage didn't show me anything different to normal..

this may be since the boost guages are T pieced, but that shouldn't affect a vacuum guage!!

Good old "Shoot out mode". Get another run done without Shoot out mode.....

[rob77]

Shootout mode is where all the correction values are locked so they cant be tampered with, or so I thought?

[Duncan]

Shootout mode is a set of pre-defined variables for an average 4, 6 or 8 cylinder car. *May* be closer to the correct variables.

[Guest RedLineGTR]

with the GFB bleed valve did the screw maybe get itself loose..or soemthing to make it adjust thew boost so high to 16psi.

Most of you twats dont f*ckin read!

the stock gauge isn't crap. it's just not GRANULAR enough to read accurately!

but hey, if you rely on the stocker and blow your turbo then i'll be the first mofo to say "sucked in, i told you so"

Answer this: Have you increased the boost on your car and do you have an aftermarket guage?

There is no way I would increase the boost on my car via the factory boost guage, and anyone that is.....good luck.

[ix9]

Yes, and Yes.

Also good luck to them I say.
