What you are attemtping to describe is Average Power, if you do an Average Power comparison  between the 2 turbo configurations it will answer your question.:)

Im talking about traction v's low down power as in the described text

I somewhat disagree, No matter what housing you get your still going to get wheelspin.

Say we have 2 turbos, one producing midrange and the other top end.  Ok, both are going to produce wheelspin in first gear regardless.  Now, second gear, one produces maximum power earlier than the other, say 500rpm??  So one spins or 7/8 kmh before the other, lets say 10kmh it is then, so one spins at 60kmh and the other at 70kmh, one has more power than the other so in my theory they would spin about the same.  And the wheelspin you get at those speeds does not really slow you down.  Now 3rd gear, if you can get wheelspin you have a mighty strong motor, so i would say the midrange turbo would jump the top end turbo initially and then the top end turbo coming over the top.

i totally disagree based on my own car.

the .82 rear housing. If im smooth through first-second it will not wheelspin one bit.

And yes it was my car Roy was in :D

I have no traction issues at all. Just using 245 sumitomo's which are absolute rubbish for grip. And ive still got lots of squat :D

If the turbo came on much sooner, im sure i would have problems. I used too with my old t04e which was maknig a lot less power, but boosted just a bit earlier.

And true to form, the Bush bearing turb was like a light switch.

The my turbo on the motor is much smoother and progressive so it has bearely any problems traction related

    • I mean yes, if you're starting from scratch on an unknown engine yes you don't need to be doing all kinds of math in the background but if you're doing relatively minor changes like AFM + injectors + boost up with some aftermarket turbos it takes quite a bit of math if you want to do something like maintain OEM fuel + timing tables but compressed and then a bit more load scale up top. I think I've spent too much time working on big engineering nightmares though so I'm a big fan of trying to constrain the scope of whatever work I'm doing as much as possible and trying to get it right before moving on. For example, a local owner just did the usual E85 + single turbo conversion to his R32 GTR and nearly burned his car to the ground doing some spirited driving up the local mountains. Turbine is unshielded and too close to the hood insulation. It's tough to balance "just get the project done" and "seemingly small details can cause massive setbacks I'm not willing to deal with".
    • No idea about Neil's steering wheel, but I have the same behaviour in the Stagea. I doubt it has ever been messed with so might be normal. Indicating to turn right at a roundabout and correcting even a little bit to the left to go around will cancel the indicator. Never considered it an issue other than it being a bit odd.
    • Does anyone know if this is off centered? Looks like it, when I indicate to go right, but turn my steering wheel slightly left it cancels (was always like that even before I started messing around with it) was wondering if anyone else has the same issue?
    • Nothing photo worthy since last update, lots of little plumbing bits for the AAC/Cold start valves, and unfortunately I still need another couple of parts for the brake booster line and the AAC into the plenum. Otherwise it all looks good to start up engine wise, onto checking the electrics/interior
    • Good news mate, plenty of spares available 5:40
