hi mate silvertop oil pumps are prone to the cast internals of the pump failing due to harmonic distortion at 7500rpm and not the bhp figure . the failing of the oil pump is a major issue and will ruin your engine (just look at luca thread as it fooked his 2000 mile engine up) . there are 3 options mate
1 dont rev the engine over 7200 rpm and make sure you use a new genuine ford pump
2 take the standard pump , strip the internals out and get them machined out of forged material ( and sell them as theres nothing on the market at the minute and make yourself a few bob)
3 scrap the standard pump and fit a full dry sump system
the black top engine is a different story as you can buy billet oil gears for the standard pump which takes all the worry away , anyone interested in them contact austenw on here as he had them custom machined for his engine , and no they dont fit the standard silvertop pump before you ask.
they would cost no more than Ł100 in my opinion to get machined and would solve a massive problem with these pumps , so its worth the trouble if you know what i mean
hope this helps
cheers paul

I have been asking CFM of usa for a long time for the black top uprated billet gears but he said that they are getting a hard time getting them from there supplier also i contacted puma speed uk and the same problem ,it is a fact that all zetecs that rev more than 7200 rpm tend to break the oil pump gears so dont take any risks as it will ruin your engine , so i decided to go for a dry sump system

they only rev to 6750rpm standard rite??
so will 7000rpm be a safe limit?
a turbo'd engine will make most of it's power mid range then drop off so is there any point raising the rev limiter??
u can shoot me down now if ya want.![007](https://passionford.com/forum/images/smilies/bond.gif)

i think some people are getting mixed up the blacktop. cfm do the gears for the blacktop but not the silvertop.
and a blacktop will rev to 7200 all day and not smash the pump as thats what the rev limit is on a st170 and its the same pump.
my own engine has been hitting the limiter for the last 4.5k with no probs .
