I didn't think there was any point in using cams with a 28RS though, or are you just trying (and succeeding) to confuse me.
I thought (from all our previous NW RR days) that the 28RS ran out of supply as you got to higher revs and go only make about 1.2bar, so it wouldn't be abel to supply enoguh to make best use of the cams, whereas the 2871 needs the cams to make best use of the extra air it is able to supply.
If that makes sense.

Jez, you've really got me thinking here.
I want a bigger turbo, either 28RS or 2871 to go with your stage3/3a.
I don't want to lose low torque though as that's what I love about your stage 2, the instant go from almost any revs.
So, I was thinking of 28RS to keep this, although I was tempted for the 2871 to trade a little on the low range for better top end.
However, if I went for 28RS and went for cams as well, jstu mild say 256 poncams or someting, have you got any experience of how this affects stage 3, would you lose more low end than a 2871, or lose less, and would you gain close to the extra top end of a 2871 without the longer spool up time.
I assume I'd need a stage3 and then a custom map if I went for 28Rs and cams.

Do the stage 3a chips work with the .86 version of the 2871r?
Just a small notice.. I am using the .86 version and it seems to work good as hell.
I will check for detonations and also check the poweroutput on rolling road later on this or upcoming month. I will post the figures when I have done that.
Jez you have PM
