Peter.  I want to run it that rich just to have a bit of a buffer zone as i will give it a hard time and just want to make sure its safe. Id rather sacrifice some hp and just make sure it doesnt ping. As with fuel thats the most that pump is gonna give at those afr's. Fabs gtr went about the same hp with a single 044 so im going to use 2 with a surge tank . Cams it is using are HKS 272 272 step 2 10.2 mm lift which isnt huge lift as they go up to 11.8mm on some. . As for target boost pressure this turbo should be in its efficiency at 24-27psi so thats what im heading for. Also lift the limiter from 8k to 9k when it has a fuel system to support it.

Why do you think it is the fuel pump? Have you monitored the fuel pressure on the dyno? If the pressure drops that means the pump is running out of flow capacity. With 13.8 volts via a relay and direct to battery connection the single 044 should have more than enough capacity to handle that sort of power.

:rofl:

ok cool

thats a pretty big buffer but ha each to there own and rich is safe

so by way of a the 800hp turbo at mid 20's psi with high lift cams and spinning it to 9000rpm you must be think around 600rwhp then at a guess.(or did you have a target in mind)

and if your going to spin it pretty hard what oil pump you using out of interest?

pete

sorry to hear about the box

Thanks yeh box is a bummer hopefully new one in by weekend. Im happy where it is at the moment as it feels nice to drive with not much lag and good top end. Im thinking in the mid 20's it may go near 600rwhp but until it does that i cant say what it will do but it is a good sign to be making good power at lowish boost. Its running a JUN oil pump.

I hope you have a large cost-effective supply of gearboxes...you'll need it

simon doesnt learn....

he went through about 8 or so rb20 boxes and still didnt learn

how many gtr boxes have to be killed :uh-huh:

car goes very nicely, was shotgun in it same say as the dyno run... can't wait till more boost and better tune

PLUS A DECENT GEARSET ;)

hey simon nice results :uh-huh:

pitty you sold me the spare gtr gearbox you had haha :)

goodluck and hopefully u can take me for a spin when its sorted to show me some single turbo power (and maybe ill convert mine to single haha)

cheers :D

    • My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.
    • Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?
    • What about if you just give it direct 12v and earth?
    • Hi guys . Can someone help me  I bought an Android screen for my Nissan fuga but it won't turn on   
    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
