hi there...

My friend are currently rebuilding his buttom end for his 4x4 saff... wit std cosworth pistons and bearings... but he wanted me to ask you guys if there would be any advangedes in buying a highpressure oil pump insted of using the std oil pump?

the spec is:

std head, wit venier pulley
Light blue injectors
mongoose
RS 500 I/C
GT 30R rollerbearing turbo





cheers

 

standard pump will be fine, unless he's using a sandwich plate and oil cooler radiator, in which case a high pressure pump would be better

 

Mine runs like this with a standard pump and had no problems with oil pressure, been like it for 9 years now

I've been told that a oil cooler kit will reduce the oil pressure, so either you must have a good un-worn standard pump, or you're basing your reply on not seeing the standard oil pressure light go on, which is at an unfeasibly low pressure that won't save your engine by the time it lights up (and not viewing the actual oil pressure on a gauge) ? (a query, not a dig)

 

I have a capilary oil gauge and when at hot idle i have 34psi.

Hot running is 50psi.

Steve.

 

fair enough - standard pump sounds fine then, oil cooler or not

 

Sorrry for hijacking the post here but does anyone know the what pressure both pumps create in an otherwise standard engine?

 

sandwich plate.. please explain mate

tanx for the replys.. I'll tell my mate

 

Sandwich (take-off) plate with separate oil cooler rad (thus cooling oil by air flow) replaces the standard modine (oil/water cooler) that sits between the block and the oil filter. Useful for lower oil temps on track cars.

 

I get like 41psi at 1,000 rpm w/ oil cooler sandwich, remote larger filter. no probs.

all the stuff makes it a pain to check oil though as it all drains back into the motor fairly quick.

at about 200rpm I get 20 psi. LOL

thats heck of a lot mate,im getting (hot engine)28 psi idle and 60 psi 2500+ using a graham goode uprated pump and a very fresh engine running 15 50 mobil 1

 

whats your idle at? ... I think its psi... it is a race tech gauge, so maybe it reads something other than psi.
