Ask steve @ sst. I wont be going down the drags till I have the wolf3d in and tuned. Dont see the point in going until the car's setup right, plus my tyres are hitting about 12 months in age, although not completely lacking in tread I'm sure they wont be as good as new ones but I'll still give them a try. I think my stock ecu is ****ed, in the mornings (cold or not) the car searches up and down, sometimes to the point of stalling but doesnt quite and then finally settles on about 1500rpm till it warms up and then sits around 650rpm, sometimes the car idle is lumpy too, but I think thats spark plug related.

Mine does that. Grant told me what it was. Can't remember now, something is a little out of calibration. Computers not f#cked.

Mine does the hunting thing too on cold startup every now and then.. I find a tap of right foot seems to sort it out pronto tho..

Robbie i dont think you will reduce your lag marginally with an exhaust manifold change

Your kidding yourself, the ex housing is too big and the efficiancy range is way off what boost your stock internals can handle

Im guessing 100rpm better spoolup with the manifold. maybe 100 rpm more with the tuned computer but even that is optimistic

down the drags you poofs

At "The Clink" in freo, this friday night. Event starts at 10pm goes to 1am or so. I may or may not be presiding over part of the nights event, subject to my wife being there. :)

The stock internals are pretty strong, the problem is the RB25 compression is a tad too high to start with.

Rob's got a 'cadbury turbo', a bar and a half of full boost.....

    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go. 
    • More so GReddy oil relocation kits, sandwich plates, etc. all use 10AN fittings. And same, I've only used 10AN and my car sees track work (circuit, doing laps, not 10 sec squirt business).
