me thinks, that if after peak tourqe, and hence peak acceleration of the rollers, the momentum of the rollers continue to spin, it could unlock the converter. I'm looking at the graph, and it does actually look like phenomena occurs just as the steep ramp levels off a little.

I'm not sure if i explained that correctly.

Darren - does it do this on the street as well?? If not, ill put $100 on this theory! ... in net land of course :D :D

Hey

looking at the graph its a fairly drastic flat spot / dip in the curve, yet on the street its not really felt.

im running a 2.8 - 3k high stall which feels nice and tight and i would doupt it to be unlocking as,

the issue is starting around 3700rpm so i would think the convertor would be locked up hard at 3700.

im thinking it has more to do with the vct changing at the same time as the waste gate is opening causing the turbine to slow down a little.

or something like that.

      Thoughts on this .. G35-1050 pulsar result

      Nope, still smaller rear, put on the 4inch exhaust and picked up power everywhere, ended up just shy of 800rwhp.   Didn't seem to be hitting any walls either, so perhaps could have pushed for more but all maybes and the fish that got away etc etc.

      This could be sold and shipped to the US for many gold pieces. RMS has no say in that. Ask various Western Sydney inhabitants how it works.

      Ha ha ha, mine loves to spend, all on the dogs (they're our kids, and her spending would likely rival that of some people raising children!) the only benefit is, her spending is tax deductible as she runs a business in the dog industry 😛 The above all means she can spend race car budget quicker than I can. 😛 That and a lot of the things I want are very expensive, and I can be a bit "you want how much for that?!" And at other times overly impulsive. Or I start the w days of research, get to day 1.5 and get really annoyed that no one will advertise actual specifics and it's just marketting BS and I go "well, now I don't want anything to do with that now!" Also I hate paying lots of money for something I can make from $50 in materials. Then I get the shits halfway through making things and wonder why others who just buy parts have more fun... 😛

      Their 240Z with the RB26 would be a real nice thing to have in a garage to come out for an occasional weekend cruise It's such a cool thing in so many ways Sadly, we have a blue 240Z shell that I walk past every day, just sitting outside a shed at work, it has been slowly disintegrating and falling apart into the ground for the last few years, the owner cannot be found, and I am unable to "claim it" I've been told by work and the RMS, the rust in the body is excessive though, and it has had most of the salvageable stuff, like panels, trim and switch gear stripped off it over the last year or two, work keeps threatening to put it in one of our metal scrap bins, I wish they did though, as it makes Mark sad walking past it
