Boy - I am just full of questions today!

I looked again in the archives with little success on finding info on accusumps.

I am trying to build a safe, fast, and reliable race car and I would imagine that an accusump is part of the reliable piece. It seems like cheap insurance to me, but I have also heard its just more things to leak and go wrong.

Are there any opinions good or bad on whether or not this is a good investment?

Thanks!

 

I believe its illegal in scca and nasa, dont know why.

 

Accusump is definitely legal in SCCA. I am not sure where you are getting your facts from...

The last time I checked the GCR, accusumps were allowed in SCCA improved touring. What is your source of information that they are illegal?

 

legal!

My mistake, it is legal, sorry!

You are probably thinking of Dry Sump's which are illegal in SCCA IT and NASA HC as well as various other touring car type classes.

Poster, Accusumps like you said are cheap insurance. Ones going on my car.

 

Who has the best price on these anyways?

Good question. At this point I'm aiming at baffling my stock pan... but more insurance couldn't hurt.

 

I was talking to a couple guys in the Porsche Club who were prepping @ Watkins Glen and they said it didn't work well and was a waste of money. Not much other info was offered other than they tried it and it didn't work well.

I find this pretty hard to believe- Canton makes extremely high quality products and I find it hard to believe that wouldn't work well, considering its design and the principles behind it. I would say make sure it is installed correctly and go for it.

If for some reason it doesn't work out- they do have strong resale value on ebay.

I can't believe that there are this few opinions on an accusump....

 

i have one on my vintage super seven racecar.

it works great; when the motor starves on hard right handers (always does this) the accusump feeds oil and keeps the motor pressurized; you would notice the gauge slowly sinking from 60 psi towards 30 psi; that was when it was feeding off the accusump. when the turn ended, the pressure would jump back to 60 and the accusump would refill for the next turn.

kept my motor alive for 5 years. then i broke the timing chain (but thats another story!).

i am not sure about the pca guys; if you were talking to guys with 911s (or any variant thereof), they don't need accusumps; they have factory dry sump systems.

now, lots of 944 guys run the accusump. they have oil starvation problems with their bottom ends. lots of problems....

good luck

Oil starvation = BAD

Avoiding starvation = ALWAYS good in my book

I don't see any bad side to this coin, it's definitely a good and viable option IMO One will definitely be going on my car when it gets built.

The average price I've seen on these are between $150-170. Check Google and you'll find a bunch of suppliers.

 

I have an Accusump on my F Prod CRX but as most everyone knows the car has yet to run in many years. I bought mine from Racer Parts Wholesale IIRC. I have the manual valve model and it is "T" fitted into the oil return line from the oil cooler with an anti-backflow valve to keep the Accusump oil all headed to the engine if needed.

My path is: Oil out from block from oil fliter adapter to Peterson Racing oil filter to cooler to anti-backflow valve to "T" from Accusump back into the block at the oil filter adapter plate. I increased the line size from the"T" fitting to the block larger than the rest of the line to help with flow. I have not made any changes to my oil pump, don't know if that will b needed.

Hope this is helpful. When I plumbed mine, I knew very little and found very little guidance of what to do.

 

They were 944 guys that I was talking to- one switched to a dry sump- perhaps the starvation problems on a 944 were too much for the Accusump to handle?

In any case, I plan to get one.

I had planned on running one as well. A 2qt unit.

Another benefit would be that the Accusump can store a pressurized amount of oil for cold start-ups to reduce or maybe even eliminate the amount of time that the engine has little or no oil pressure.

I have a couple of ideas for plumbing the Accusump. I'm not sure how appropriate they are b/c I'll never get a chance to install the ones that we have sitting around.

1.) Run a remote filter using a sandwich plate. Use a spin-on adapter with the OUT hole plugged up and use the IN hole for the Accusump. I'd imagine that this would eliminate the need for the requisite check valve to avoid pressurizing the pump side.

2.) Run a remote filter system using the spin-on adapter and tee the Accusump into the return line of the remote filter. This way would require the check valve.

Thanks CRX Lee for the advice! What size accusumps are people using and which valve is better? The electric version or the manual valve?
