Thing is that I ordered a uprated pump where I got my engine rebuild, but I think it a bit low ..?
idle .............. 55 psi cold and 28 psi hot
2000 rpm ..... 40 psi hot
3000 rpm ..... 48 psi hot
raising to approx 52-55 psi hot when taking higher rpm's.
I dont know if it matters, but I have a external oilcooler mounted and i'm using a mobil 1 oil, (5w50) ??????
mine is up about 5psi on these figures, new standard pump on new bearings regrond crank etc
hmmm..sound like I only got at std pump
...but payed for a uprated
I also got new bearings and so on as it was a complete rebuild...
....
so if there was another problem...what could that be ??
