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.

*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!!

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. :D

      Ethanol Content Sensor - Always at 11%?

      By joshuaho96 · Posted

      The incentives are mostly the same, yes. Ethanol is cheap compared to the cost of doing 98-100 RON with crude oil alone. 87 to 93-94 AKI all with E10. In 2020 Canada mandated E10 as a part of their "renewable fuel standard" and is supposedly going to go to E15 in 2030. In California where there are only 8 refineries with two threatening to shut down next year it's been over 20 years now of E10 and 91 AKI maximum because there's just not enough refinery capacity or crude oil supply relative to the demand for premium unleaded fuel. And CARB's low carbon fuel standard means functionally none of the diesel available at the pump is made from crude oil anymore. It's almost all entirely 20% biodiesel blended with 80% renewable diesel (hydrotreated vegetable oil) now. The number of gasoline vehicles that support E15 or higher ethanol concentrations is surprisingly low, I can't imagine it being wise to play tricks like this without flex fuel sensors in most of the fleet.

      It's almost certainly the same as the one next to it.

      South Australia, which is hardly as far behind as the rest pf Oz makes out, and who is also not a paragon of progressiveness (read that as over-legislation) in the area of vehicle standards, has this to say on the subject: Adjustable coil-over suspension Aftermarket adjustable coil-over suspension components are suspension units that incorporate an external thread on the main body and corresponding threaded spring saddle that allows the vehicle's suspension height to be varied. If fitting aftermarket or coil-over suspension components you must submit an Application to modify a light motor vehicle form and a report from a light vehicle engineering signatory (LVES).

      R34 GTR Seats / No longer reclining

      By bilbo117 · Posted

      Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers

      Those above shitboxes, mediocre and above usually have a turbo strapped to them, hence the slightly higher octane is required.
