Is the 34 running -5's?

And they are on race fuel aren't they? Last time I was out at Russels they had drums of Sunoco or Martini or something like that

i was fairly sure they were using E85 and -5's. as it kept the response similar to how it was on the R32's engine.

1 min in mark says its running E85

Also other 400rwkw/-5 - Aaron34, pretty certain it was 400rwkw and pegged back to 380 as it was seeing extensive circuit.

tangomatt also, 415rwkw. Pics of -5s :(

that is a beast! i will spend time reading thru both threads, thanks for sharing

how about smallest turbo that is running efficiently for the power application = win?

where do you draw the line at being 'efficient'?

I would say running 20psi on a highflow is past its efficiency but they make for an awesome combination on a street car!

I suppose you draw the line with EGTs, going past a turbos efficiency will increase the EGTs no doubt. But I suppose if thats still in acceptable range then thats still ok. Although I would prefer to drop a few psi and get right in its efficiency zone.

yeah, you can still have fairly acceptable EGTs and be well out of the efficiency zone a lot of the time though which was sort of what I was trying to say.

sure the turbo is putting excess heat into the intake charge but it is still scavenging energy out the exhaust so its still being more efficient mechanically than an NA vehicle, but you are right, it is a nicer option to have temps etc all well under control so you can drive it around on a 35c day without issue.

    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
