zim Posted September 24, 2011 Share Posted September 24, 2011 As per title, I've got a challenge next weekend and my zf74 is pretty much kaput ! I'm getting about 500psi out of it (testing it against it's pressure relief valve). So....will a p38's v8 pump be the same or more than a RRC v8's ? Reading rave the p38 seems to go up to about 1500ish but the rrc to about 1100. Cheers G Quote Link to comment Share on other sites More sharing options...
yella 90 Posted September 25, 2011 Share Posted September 25, 2011 while you at it find out what a td5 one does pressure wise ive opened up the outlet port to 4mm and i can lock to lock with the palm of my hand at a standstill with my boggers at 9psi Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted September 25, 2011 Share Posted September 25, 2011 G, I have a P38 4.0l in my RRC, P38 pump running the stock RRC 4-bolt box, after the engine swap I believe the steering was MARGINALLY lighter, this may not help at all, but if it doesn, great Oh, and the standard RRC pipes bolt straight up to it.

zim Posted September 25, 2011 Author Share Posted September 25, 2011 Cheers. The zf74 has an m16x1.5 thread output from what i can see.This is the same as the rrc pump i fiddled with quickly last night. Dan, i don't have a dirty td5 so can't check G p.s. Just noticed, the title i wrote in the box hasn't all been displayed - it's cut the last few letters off. Quote Link to comment Share on other sites More sharing options...
zim Posted September 25, 2011 Author Share Posted September 25, 2011 Tested a couple vehicles today, with a closed output - just the gauge : P38 4.6 v8 zf pump - 1,500psi RRC 3.9 v8, with the cylinder style pump - 800-900psi So i'll fit a p38's pump tomorrow Quote Link to comment Share on other sites More sharing options...

Range Rover Blues Posted September 26, 2011 Share Posted September 26, 2011 Tested a couple vehicles today, with a closed output - just the gauge : P38 4.6 v8 zf pump - 1,500psi RRC 3.9 v8, with the cylinder style pump - 800-900psi So i'll fit a p38's pump tomorrow Is that the PAS pump from a 4-belt RRC engine or the later interim engine (serpentine)?
