Installing accumulator in GTR.. need info..

[fastco]

Hello were looking to order accumulator system & looking for some info from you fellows out there... were are most of you installing there there oil sump bottles is there room in engine compartment? Were are using electric
operated accumulator hoping to fit 3 qt system bottle dimensions are 5 inch
.250 dia 8 inches long or other choice is 4 inch dia & 14 inches long.
Bottle must be mounted verticaly.. any one with photos of there mounted system would be a great help.... Thanks mates! Daryl aka Dr,Dee

I think most of us use ones that are about 4" dia.

Ours lay horizontally on the bottom chassis rail. Not sure why yours has to be vertical though?
Is it not the same as the Accusump?

This is where they usually fit, but horizontal not vertical! Why would it need to be vertical?

Thanks Gary for pdq response & photos mate... we are using new electric
accumulator with no piston but with electric release valve......we always mount our systems verticaly not horizontly this is for system purging & any sediment in oil in bottle will be flushed out when purged.. in horizontal mounted systems sediment will gather @ bottlom of piston bore over time & score piston bore & piston.. may cause sticky & leaking operation of accumulator.. our system may be mounted anywhere in the car.. & pressure gauge is remote & can be mounted in dash for monitoring when system is activated checking systems loaded pressure & purge operation pressure.
Cheers! Dr,Dee

Accusumps have been around a long time and work very well! As they are discharged every time you start the car there is not really a problem with sediment forming. The accusump works without electronics which is a big bonus! Introduce electrics you add problems. And this is an Avionics Engineer talking.

Hello yes indeed accusump /Moroso has been around a long time approx 50 years.. my how time fly's & technology changes the new systems are very quick to respond to oil pressure drops 3 to 4 times faster then the old systems & empty & recharge @ a much quicker rate & use no restrictive sandwitch plate adapter needed with short style filters .New systems allow use of longer filters that have more filter surface area & less oil retriction & better flow rates then short filters. New systems mount anywhere in your car & the pressure gauge is remote dash mounted... giving the driver a heads up & more needed direct info on how & when the system is functioning.
A recent test on accumulators systems was conducted with the new systems by Ford Motor Sport race team USA & was done over the last 2 years under all out race conditions with the old systems there was approx a 40% engine failer rate due to oil starvation of bearings in there engines under severe
racing condition . They then switched all cars to the new systems & engines failers due to oil starvation dropped to a 5% average due to oil starvation
they are very pleased to say the least.
As most of us have seen our oil warning light come on with the old system it takes 2 to 3 seconds to release it pressurized oil the then oil light goes out.. this can also be seen in NASCAR race cars with cabin mounted cameras.( NASCAR is ruling now on the use of the new systems)
This delay is causing engine bearing damage while the bearings wait for presious oil to be feed to them. With the new system mounted in the cars the oil warning light never comes on.. why the system is keeping up to the demand for oil & is 3 to 4 times faster to respond then the old system.
Just a heads up mates... Cheers! Dr.Dee

PS: New systems are avalablie in mech or electric controls.

Just fit a dry sump system!!!

[CanAm Dave]

Good point Peter

If I was as worried as you seem to be Dr Dee, then why not fit a dry sump.

Regards Dave

How much would it cost to fit a dry sump system? Im about to fit an Accusump for track days.

[fastco]

If money no object i'd go dry sump system.. add couple 1,000 pound sterling
to the build costs & 20 to 30lbs + weight to your car. Cheers! Dr.Dee

"Just fit a dry sump system!!!"

Hello,

I'm building a GTR with the LS2 engine.

-> Where can I get a bolt on dry sump system for my LS2 engine?

Thanks & Regards
Oliver

Try these guys, they are in Melbourne Australia, regularly build special and one of components for general motors Australia (Holden), they do superchargers, big brake kits, stroker assemblies, individual throttle bodies, and a nice cast LS sump with an integrated dry sump pump mounted on the side of it.

oh yeh, and in relation to the accumulator, the yellow gtr from the targa Tasmania had it mounted vertical on the rear of the firewall, left hand side of car. Se the photos on my site for more info

Anyone put a druy sump oil system in a center shift, left hand drive car? Where did you position the sump and where was the sump purchased from?

[craig-ultima]

I have both a dry sump and an Accusump. I use the accusump (electrical control valve) to pre-pressurize the oil system before starting up, then the dry sump gives ideal oil pressure while driving.

Although this is probably overkill, there is nothing like having 4 bar of oil pressure before the engine cranks over. I can actually hear the oil gurgling through the engine before ignition, while sitting in the driver seat.

The plumbing is very tight when you do both a dry sump and accusump, but it works. I have photos etc at www.craig-ultima.com
