Thanks for the info, I will talk to the guys at the shop about it. I also remember seeing something about if it gets over pressured it has a valve that releases oil, has that ever happened with yours? I don't want to be the guy on the track with the 007 oil slick!

BGTV8

A sump spacer and/or extended sump with baffles will provide an additional litre or so, which will be a reasonable safety margin for most track-day aficionado's using R-Spec tyres (RS-3, AD08, R888 etc) where the session length is 15 minutes.

Running full race (longer duration events, full slicks), then an Accusump is the minimum insurance, but serious amateur or semi-pro competition then the only solution is a dry-sump system.

I track my car regularly, use Yoki A048 or Dunlop DZ03G R-Spec's, and once a year run in a 6-hour relay where duration is 30-minutes and I do not get surge with a JWT sump extender, oil cooler and an additional litre of oil in the engine.

However, if I was "racing", I'd install a Dailey Engineering dry-sump.

Tread you own path, make your own decisions.

The safety valve is set quite high. I cant remember on top of my head but you need a serious issue to pop the valve at 200psi+

This is why it shouldnt be in the car unless the safety valve is setup to dump the oil someplace else other that just by the Accusump itself.

The car is a DD on street tires and we run 25 min sessions, nothing serious. I just want to have as much safety for the motor as I can have reasonably. The car has a lot more power than the last time I tracked and I want it to stay that way. Last time we went to Sebring we trashed the motor of a 650 HP Trans-Am because of oiling problems and it has me a little gun shy.

Thank you both for your input!

Yes you must be the only person serious because I don't recall many stories about people losing motor. Perhaps you should be looking at your 8000 rpm redline instead of blaming the design of the motor.

They have track insurance for some events, usually with about 20% deductible and they cost the same as a track day.

Megan370z

You must have something for me . You keep comming....
Not my fault if you cant see the facts.

VVEL got damaged due to oil starvation that was caused from the big tank slapper and doing an additional 360 after the tank slapper happenned.

this is serious and yeah there a very big chance the vvel got damaged because of this ... it was not at a point on the track I was at full revs...
I took the exit at like 300feets from where it happenned..

I couldnt complete another 1-2 laps after I went back on the track when the car cooled down ...the vvel got broke at that point then I left the track and whem home driving the car at low speed then 200kms the oil pump exploded because of all the crap....

so yeah stop saying that I must be the only serious guy that track his Z because as far as I know there is quite a few on here . Mike.spoon.travisjb.bgtv and many other . So stop that crap on me .

Also read what bgtv just said which is even worst than what I strongly suggest... why arent you on him ?

by the word worst . I meant he recommend something even more expensive that what I suggest

imma get a Accusump eventually, but AFTER i do the Phunk Road race fuel pump, setup a diff cooler, and get a second set of track wheels :P

cossie1600

I really don't have anything against you. I just found it stupid to say the oil pump is necessary when there are only a handful of failures. I am sure others have done tank slappers and they don't end up with blown motors. I think you just stressed the crap out of your motor when you ran it at 8000RPM. It's simple math.

Megan370z

that's your option.

OK read carefully now I'm repeating something and making it short for you.
My opinion and fact is after that tank slapper/360, I went back into the pit, cooled down, when back up on the track doing a warm up and couldn't even finish it, so what is the most probable issue there ? 99% chance is Oil Starvation you cannot deny it. that's a fact of how it happened to ME.
CAN YOU FK UNDERSTAND THAT ?

like BGTV nicely said;''Tread you own path, make your own decisions.''
The OP basically asked our opinion, mine isn't good ? yours is better ?

so who's stupid now.

now target somebody else who mentioned about other less/more expensive preventive safety measures.

I'm done with you kid.

I am simply saying your one motor blowing up doesn't mean it will happen to everyone. The odds are low

nismo13807

hmm.. thanks everyone that pitched in their experiences and gave their opinions... i am currently leaning toward a oil accusump unless i come across a baffled pan first.

Megan370z

I did agreed with some of your previous comments before in this very thread and yes.
the odd are low/very low but some peoples doesn't want to take the risk.

That's why I brought up you are more likely to wreck than blowing motor. If you want to be safe, that's fine. I just want to point out there are simply not many blow ups

Same with overheated oil too
