watch out for speedbumps...

i cant even run a tuna can on my car....

[machina]

every type IV I have seen at the track has one hanging down, unless the motor is dry sumped.

for a street car however, it is risky and probably not necessary.

I couldn't make it around the track at all without my deep sump. Even the force of braking would cause starvation at the pickup.

The sump or tuna can is a must if your are going race your 914-4. I used the sump on my 914-4 race car but it got ripped off the bottom of the engine twice while racing at Sebring. For that reason maybe the tuna can is better. Without the sump or tuna can, on very high speed turns on a race track or on very fast sharp turns in an autocross, the engine can loose oil pressure. Without a sump or tuna can the oil will splashing to one side of the engine away from the oil pickup which results in loss of oil pressure.

I've got one and it's all scratched up by the PO. If that's any indication of how low it hangs.

I keep thinking about getting rid of it...it is a street car after all.

Been running one of the sumps I sell for the past 12K miles in the teener and even living on a dirt road I have yet to scrub it once... The engine is so close to the rear wheels that you glide right over many obstacles..

Hey Jake, which sump do you sell?

[Brotherbob]

I have a finned deep sump that I plan on using but I wonder about the hook ups?
I have 2 outlets on the sump , 2 on the engine (cooler removed) , and a new oil cooler in the front bumper.
? Which hose goes where ?
I dont have my engine in yet but it doesnt look like a clearance issue ?!! (IMG:http://www.914world.com/bbs2/html/emoticons/hijacked.gif)

Are you wanting the extra oil capacity or the non-oil starvation?

If just starvation, go with a tunacan or one of those external pressurized sumps that add oil when pressure gets low ($75-$500).

Thought a little xtra oil will keep things a little cooler? and starvation in hard cornering? (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)

Yea but your 914 is too high. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)
I run a tuna can which does sit in line with the rear wheels as mentioned above.
No dings.

[nebreitling]

yup, i can't run over speed bumps in my car, and i scrape driveways all the time, but i'm not too worried about the tuna can. it would take an odd object to knock it.

i think if you run R-compound tires it's necessary -- otherwise, i wouldn't bother.

[roundboy914]

I had the deep sump on my street/track car - and after 1000 miles it was trashed. The tuna can works fine, and doesn't hag nearly as low. No problems with oil pressure even on long sweepers like the carousel at Road america.

I sure as hell would bother! With mediocre 195-60-15 tires, I was able to get the oil light to come on in sweeping turns. The one at the "far end" of the Santa Rosa Airport autoX site was one such--that was what convinced me to get the tuna can in the first place!! Freeway on- and off-ramps, too.

Now, with the tuna can and an extra ~1/2 quart of oil in the sump, I only have oil-light issues after about 3.5 on- and off-ramps in a row. (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

[nebreitling]

wow, dave... this was in an otherwise healthy engine with good oil pressure? it seems a little excessive in a stockish car, but i suppose that tires have come a long way in 30 years...

as soon as i can come up with the scratch, i'll be accusump-ing mine.

[bernbomb914]

I think there are two differant size sumps. one hold about 1.5 quarts the other about three, which would hang much lower
