Wow. Just caught up on 180 pages in the last few days after not visiting Sau for ages. Still an awesome thread. Some excellent improvements and results Stao!!

Finally getting my SS2 off its run in tune soon and adjust for the change in cam timing. I'll post results when I get them.

What did you mean by 'run in tune' ? I've got a SS2 that's going on soon as well

I didn't get to see the tuner the day I dropped it off. He saw it had a new motor so only set it about 17psi and not much timing. Time to put some more hurt on it now I've dialled the cams and got rid of the lag it initially had when cams were retarded.

Some updates, This is an internally gated prototype that I've been working on few weeks, the goal is 370rwkws on E85 fuel with excellent drive ability, internally gated bolton to factory RB's manifold, dump and all lines.

My final result was 365rwkws @ 23psi E85 and 330rwkws P98 @ 22psi. 20psi was reached at 3800RPM, while made over 200rwkws @ 4000 using either fuel. This is probably the highest power any one has every made using a bolton turbo. I'm very happy with todays results.

Anyone remember when the SS2 reached 20psi ? It was a while back and couldn't find it. Currently can't decide between the SS2 or new ATR45

That might I've been my dyno results im running 21psi internal gate 297rwkw on p98

4000rpm give or take a few hundred depending on mods and turbo specs

    • 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.
    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
    • Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
