Greetings lads. Don't mind me, Just testing a new sig. Carry on...

AFR stands for air:fuel ratio. A measure of how much fuel:air in the cylinders. its measured by an aftermarket wideband oxygen sensor, in the exhaust. 14.7:1 (14.7 parts of air to 1 part of fuel) is the golden number where all the fuel ignites and is the most efficient point for petrol engines. Under boost/load, that number should drop down to 11.0-12.0, or even lower if the car is running rich. any number higher than 14.7 is lean, and any number below 14.7 is rich. Power FC is an engine computer made by Apex'i. One of the best options for skylines and silvias. They plug in, offer full control and are fairly easy to tune. p.s. SAFCs are pretty average. They only alter the air flow signal to the ECU, so they are no way a good tuning device. they are good for anything less than ~190wkw. Anything more than that and SAFC really isn't a smart choice.

Win!

Perfect. That's exactly what I needed to read. thanks!

True hahah... Only problem is this car is my daily, so intake manifold off, fuel rail out, sending fuel rail off to be welded, running a return line down the back, tuning it all on the street etcc.. would take more than a weekend! But from what I see, it'll work just the same return or returnless. Scotty do ya reckon the aeromotive FPR I linked above would suit? I've found a good seller on eBay and a good price! From what I hear they make good gear, and it's got the right number of inlets/outlets...

Woah that's a huuge job! Wouldn't it be just as effective to run the FPR and utilize the stock line, like my amazing paint drawing described? I've heard the limit for a returnless system in the Sentras (same engine, car in the US) is about 400hp. I'm nowhere near that at the moment. It should work returnless no problems. I wanna avoid going to a returnless system as much as possible, it would be a karnt of a job, and I can't justify doing all that work if i'm not planning anymore power down the track...

The stock system is returnless, and there's no extra fitting on the end of the fuel rail to run a return back to the tank. And as far as I've seen, there's no aftermarket companies that make a return style fuel rail of good quality. Nah I've run out of FPR flow. The stock FPR in the tank isn't boost referenced and I'm guessing it's running out of flow and the pressure is dropping at around 13psi on this set-up. Max boost sees 76% duty cycle from the injectors, and I've got a genuine 500hp walbro in the tank. The only other link in the chain is the FPR, so logic says it isn't up to scratch. Stock set-up is a pump, filter and FPR built into the fuel canister. Pump receives a constant 12V (have checked it), base fuel pressure is 3.5bar, and the line's size is 7.95mm (5/16th)... p.s. thanks for replies fellas!

Hey. Looking to upgrade my fuel system, and my car has a returnless fuel system. My stock FPR in the tank is not up to the job of making anymore power. I need a non-return, boost referenced FPR. Would this work? Here on eBay That aeromotive one has one inlet and three outlets, so in theory i should be able to use that in a returnless system right? Like this: Yeah? Any other models of FPR that would work? Basically I need something with an inlet, outlet AND a return. Thanks.

Lol wut?

In an R33?

Wut?? what good would an RB20 harness do? Why doesn't it have a CAS? +1 for intercooler piping leak.

So this guy's got a commonwhore and a soarer, and he's giving you shit for owning a GTR... Tell him to buy a VN, then moor it next to the other boats in his garage.

You sir, Win!

In.

Me too!

Have you hooked up the vacuum source correctly? $100 bucks says it's not installed properly. The vacuum source needs to come from the intake manifold, after the throttlebody. Why are you putting a BOV on your car? They sound like shit and they will cause problems for sure! You'll most likely have problems with stalling and a poor idle!

My $80 oil pressure gauge from supercheap works a farken treat. So simple and reliable!

Carton of beer + $50 I'll do it for ya. Easy job.

CHEMICAL BROTHERS!!!!! so excited!

Yeah hot bits... http://www.hotbits.org/catalogues-detail.aspx?makeid=24&kitsid=290 I'll be ordering the coilys within the next month or so. Stock brakes are fine. They are pretty big and stop the car VERY well. The stock brakes and the wider tyres that I've got now work well together. I'm just about due for some new pads though, will be getting Green stuff pads. Wastegate: Tial MVS,, 38mm, v-banded etc... Booked in with Kermit for the 12th March for a new dump and screamer etc... Will post vids of some pulls with a screamer...

are you kidding?

Dunno what everyones goin on about, I had Khumos, then toyos, now a set of Achillies, and the Achillies have worn the slowest, been the grippiest and the quietest?

can you take a guess as to how much end to end movement? My GT28 fresh from garrett had a tiny bit of end to end movement. It's to do with the ball bearing system...

:( What bout us full time workers? Would be keen if it was another day!

Talk to Andrew from Hyperdrive. 92093100. Although I'm bot sure if he's got his dyno up and running yet, recently moved workshops, but should do by now. I wouldn't let anyone else touch my car. A good trusted tuner is rare in Perth...
