Thats weird about the AFM, I was under the impression they flowed well and only really need changing when going for big power as the tuning resolution is a better with a Z32 item. Mine's only running about 180@wheels anyway, and I need to get the sus/chassis sorted before I need anymore :(

Mine was maxed a little over 180rwkw as well as another mates.

Perfectly normal. You can tune them up to around 220rwkw odd but its a fairly rough tune. Essentially when the afm max's out you push in enough fuel at that load point to handle the boost being run. So what occurs is say its tuned for 15psi but the afm max's out at 12psi when it hits 12psi it runs the ignition timing and enough fuel for 15psi so not optimal.

But really you never try (thats if you were good enough to be able to do it) to hold 12psi at part throttle with the afm only just maxing out so usually it goes unnoticed. :(

The Z32 allows for a fair bit more scope. Mine went from maxing the std afm out to ~4.2-4.3v on the Z32. Then ~268rwkw was ~4.7volts and now 302rwkw is high 4.9volts on occasions flat 5volts on those cold nights. So nearing its limits again. :S

    • Meh, I've always used 140-200TW tyres on the R32 as a daily. A set of tyres every 8-15km is acceptable to me. 8k perhaps at the less acceptable end!
    • Replace with a used tank?
    • Lots of tyres were quoted above, plenty of people have shown up to cruises on many of them.  Winton sprints allows full slicks and semi's in my category (C1, race car up to 2L), and semi's dominate the class.  You've got to set a car up properly around slicks, semi's are much more forgiving and the setup can be more versatile for a multi-use car.  I've got some used slicks fitted to the wheels already for the Silvia so we'll see how I go when the time comes. 2 sets of wheels is almost always the answer for a weekender. 
    • Well yeah - I know the tyres quoted above are technically road legal, but nobody shows up to a hill run or a cruise on them, because they burn too quick and they GENERALLY exist as the "track only tyre" for an otherwise road/track hybrid car. I suppose they could fit the bill to drive *to* the track on them instead of changing tyres there on the day. I suppose it makes sense when it comes to slicks. Otherwise you'd just drive to the track and change tyres. And if you're gonna do that I don't know why nobody picks up a slick for those uses, even for regular road car track days/HPDE use non-competition but fun stuff. I just always find it a bit funny that people will say "but street car bro on street tyres" even if said street tyres would never really be driven on the street. May as well have a slick and just enjoy the full potential on the track. *pending suspension or grip related roll overs or god knows what which may/may not apply. Nankang CRS (v2) will be my choice too in some faraway era where my car exists and goes to a track again, by which time all the options may have been updated :p. Seem to be on par with the A052 everywhere when tested back to back except half the price, and wear slower. Goes to show how fast tyre tech has come, the newest product generally is the bestererest as it comes out.
    • MMM ok,  I see a bit of praise for RE003s, but CR-S sounding like a better option, seems Nankang wants those to replace the AR-1
