I suppose the one thing I'm trying to find is if it's safe or if I'm gonna have problems with this sort of oil pressure, if it's somewhat common to run this sort of pressure in higher power Barras without issues then I'm comfortable. Unfortunately this is not one of HP junkies full billet pumps just one of their ported stock pumps so as far as I'm aware no other options for springs. I've heard of factory pumps splitting however I'm certain this is due to a lack of porting on the housing and relief circuit. I'm also still running VCT and have heard there can be issues with it with high oil pressure also.

I dont actually think the have another option spring, this is one of their ported factory housings not one of their billet options. The only thing I could imagine could be the issue if it is one really is perhaps the pressure relief valve is stuck.

Peak rpm is likely to be somewhere around 7k (cams suggest 6800rpm) Oil filter is a Ryco Looking to make around 1000 to the tyres

Hi guys I've recently finished building my engine and had it run up on a test cell. Everything has come up pretty solid but one thing I'm a little concerned about is the oil pressure. I'm running a ported horsepower junkie oil pump along with their high pressure relief spring Running 10w40 On cold start we are seeing 100psi @ 1000rpm At roughly 98-100 degrees we are seeing 32psi @ 1000rpm 52psi@ 2000rpm 80psi@ 4000rpm Does anyone think these pressures are to high or common for a Barra with these mods to the oil pump?

Hi guys. I'm in the middle of building my first barra and I'd like some advice To give an idea Im running manley pistons 9.0:1, standard valves and crow cam 3232593/3242593 cams .495 lift, crow cam vtkba6-t 110lb valve springs. The deck has been machined to 0 and I'm using a .040" cometic gasket I used the modeling clay method to check. On the exhaust side I've got roughly .300" clearance due to the piston been fly cut. Moving onto the intake and I'm finding roughly .090" clearance which is due to the intake side not having fly cuts. My question is, does anyone have any experience with the same combination or similar using these specific cams/pistons and was there an issue with P-V clearance? Also, would you be happy with .090" on the intake side? I'm very likely to spin the engine out to 7000rpm and I've never really played with VCT and I'm unsure if this would cause an issue. Cheers

Hey guys. Does anyone know the recommended clearances of a barra oil pump? Looking for backing plate to gears, gear tip and gear to housing. I've looked absolutely everywhere and can't find anything. If it helps I'm using a hp junkie ported standard housing and billet 7175 backing plate with atomic gears. Thanks

I have done the same, drilled out the spot welds and torqued down with the windage tray on top of the girdle but the studs are missing by a thread to the nut. I torqued it back down without the windage tray and the nut sat dead even with the stud. Clearances etc have already been checked and are good. I may look into machining the caps down or possibly not running the windage tray

Thanks gents. @Puffwagon I'm fairly certain I also just read a thread suggesting you had issues with stud height when using an aftermarket girdle? I'm currently running into an issue with an atomic girdle where I don't have enough thread purchase with an arp kit using the windage tray (misses by full purchase by 1 thread) if I remove the windage tray then in golden but I'm not too keen on removing it. Any idea on the fix for this?

Hi guys. I've searched but cannot find the answer. Does anyone know the correct specs for crankshaft end play? I'm running arp race series bearings with 360 degree thrust.

Ok. So remove that and even with the ARP kit we should be golden. Thank you sir

Ahh. I think I know what your talking about. I've heard stories about a random rib at the back of the sump that makes no sense get it's there haha.

Short of going to the Grinder/Dremel path. I going to assume this is rectified by using the atomic main stud kit?

Hey guys I'm curious if anyone might be able to tell me if there are any clearance issues to the sump using an atomic 10mm main cap girdle with an arp main stud kit on a BA series Barra? Thanks guys

Hey guys Is anyone able to confirm if a plazmaman fuel rail will fit with a process west plenum on a ba? I'm assuming it will for the fact that they bolt up to the standard location but want to make sure before I purchase.

Where would you start with the better angle? I have spaced it around 4.5mm and it did seem a little better (although could be a placebo) Where would you cut off your spacing in mm to say "this isn't gonna a work"
