they can handle more, but Bosch do not rate them to run at higher levels for prolonged periods of time. if you get chance to get a 413 pump, grab it, that will run 8BAR all day long, proper motorsport/wrc pump (used in series setup usually for getting the torque those engines require).
i need to get my 2.1 zt on the rollers soon, just fitted a gt3071r, big power to come i think
p.s. just destroyed a t3/t4 in less than four months peaking at 29psi, holding 26psi for the last few miles, i do not recommend going there
Not a bad shout, sounds a great spec you have too!
I was talking to a Bosch rep not long ago about availability of alternate pumps, the 413 came up but I didn't like the price tag
He basically said that the 044 and the 413 were the same pump, Bosch just grade them. So the really good ones from the batch go in the 413 pile. I suspect they may also use different sundry seals etc too.
There are some really good web pages showing test results from the 044 at various pressures. But I would be happy to see one run 4Bar static rising to 6Bar with boost.
