Link fail?

Is that anything to do with Matt Close and the Audi TT-RS at Targa Tasmania 2010 understeer of fail?

[Darkside]

Seen it now... Looks like something I used to draw in priimary school... also looks like something that might end in death in a smouldering wreck.

[Marlin]

I concurr....... no thanks.

Heya all

Techy Q

External (wet) oil pump setups. Legal for tarmac?

If so, who's using what setup?

I currently have oil pressure issues and am looking at my options. The pressure drops suddenly, not to deathly metrics, but it drops from time to time with a bit of thrashing. I'd rather fix the issue before it drops for good.

I have a spanking new N1 pump sitting here and I'm considering the Reimax gear upgrade. I have a 32GTR so I also need to mod the crank which means it's a good time to rebuild.

I don't really wanna spend the money on a full build just yet so I'm considering modding the sump (bigger, baffled and gated), throw on an external pump (sell the N1 pump) and keep driving the nuts off it till engine bits end up on the road.

Sorry for the long spiel. Purple monkey dishwasher.

Hi Mark,

this is a bit of a handball, but if you are building a car its well worth reading these regs....a few times.... These are the 2011 Targa Supp Regs. Word on the street is there isnt major changes to these at present so if you use these as a guide you should be sweet.

Off the tops of ym head I am pretty confident you are sweet with the sump, just dont knw about the oil pump, but I am sure its in there. If Stuart drops past I am sure he will have the answer.

[sav man]

99% sure you need to keep the internal pump. With a gated sump internal pumps are fine for Targa

[Marlin]

For early modern the way I read it is dry dumps are ok.

[Nee-san]

What number is that on the Bristol Stool chart ?

[Marlin]

******* to clarify, dry sump ok for MS, not you Gtr guys.

[Marlin]

Say what?

[Nee-san]

Ummmmm, ok?

[Nee-san]

Nevermind, haha.

Oh and I agree RE: the little Rothmans Jigger,

It would be a glorious flaming death.

Targa Supp Regs

Thanks DARK!!

Why read the regs?? It just shows how much everyone is actually cheating! hahahaa

General regs state:

82. Sump / Oil Filter (except Showroom)

The removable section of the sump maybe modified to increase capacity and internal baffles may be fitted. Sump pickups maybe modified to allow for modified sump depth. The oil filter element/cartridge/s is free, providing the cartridge fits without modification and does not perform any function other than filtering the oil.

With no additional info in Modern LMS

I see an external pump (wet setup) as a reliability modification without any performance advantage.

It saves me stripping my early RB26 crank out and modifying the crank collar and spending $$$ on a crazy oil pump. This way is just a sump mod, add external pump, say 3-4k all up, and it's done for ever. Unlike removing crank which means bottom end rebuild at the very least.

Stuart, any comments?

I believe reliability modifications can be discussed and agreed upon outside of supp regs?

With all due respect, the rules have been like that for years and happily accomodating GTR's for years too.

If you're concerned about the cost of a fresh engine and or oil pump for an event such as Targa, well, I'm a little flumoxed.

A few grand spent up front to hopefully ensure you actually finish what is an endurance event that WILL cost you 15 grand minimum before you scratch it or renew the car to it's former pre-Targa state (tyres, pads, bearings etc..... )

To take short cuts on reliability is a little wierd.

EDIT: I just properly read your latest post and its clearer where you're coming from. My post above was more in reply to your earlier post about external pumps.

I understand your concern about the pump, but as i say, hundreds have done it and lasted no worries previously. And I maintain that you'd be mad going into targa with an original R32 engine.

Heya MARLIN

I'm asking about external pumps as they seem to be a near ultimate fix to any RB26 oil pump issues.

I should have given more background. My car is currently a rego'd thrash/track bitch with the intention of doing some tarmac in the future.

I've recently picked up and oil pressure issue and can't afford to build a motor right now (Early RB26 crank collar required = bottom end build). However I can afford to add an external pump and mod the sump as I can move these mods between any engine and it allows me to drive/thrash the car, until I can afford to build the motor the way I want and start competing.

I just don't want to back myself in to a corner by using an external pump in regard to competition rules.

I'm sure you'd agree the external pump is as reliable (if not more) than a replacement pump, hence my question. It also saves me an immediate bottom end rebuild (to fit crank collar).

Sorry for the long reply, just my current thought process!
