Are there any disadvantages to putting the dry sump tank in the rear trunk area and plumbing it from there. Im limited to space and thought Id get some opinions.

trackboss

Not if you use a high quality pump.

BrianCunningham

most race cars have it there for weight bias

djZ06

Thats my goal, although I was concerned with the added length of lines and the correct stage pump. If someone has a similar set up please post.
Thanks

Actually, most racecars have it mounted in the engine compartment on the passenger side where the battery is. Then relocate battery to passenger side footwell or rear. Drawback to mounting it in trunk is very long lines that are not cheap, and lines running thru the cockpit.

Thats what I thought pretty much stock location, however with the chassis setup we are doing it would be better in a different location. I anticipate the lines being run through the custom chassis (boxed)with the tank positioned passenger side rear.

Some of the t1 guys are putting it behind the inter fender well on the passenger side. The one I saw was a 08 coupe.

In T1 you do not have a location choice.

DJ,
I considered doing it that way myself. Weld a piece of channel to the frame rail on the passenger side and run the lines thru it. Not a bad way to go. I ended up running the exhaust thru the frame rail and no longer had room for the channel, so I put it in the engine compartment like most others do. I did have to notch out the inner fender and windshiels shroud to get it in there.

By the way, what are you building the car for? Just curious.

DJ,
I considered doing it that way myself. Weld a piece of channel along the passenger frame rail and run the lines thru it. Not a bad way to go. I ended up running the exhaust thru the frame rail though and didn't have room for the channel so I ended up mounting it in the engine compartment like most others do. You do have to notch out the inner fender and windshield shroud to get it in there.

In T1, you're not allowed a dry sump. Is that what you mean by "no location choice" ? Not sure if you were referring to "battery" or "oil tank".

Lancer033

new rules, you can with the LS3 (maybe the LS2 too)

exracer28

T1 Corvette can add dry sump systems. Model and location are detailed in class rules. Battery to back using factory Z06 mounting and I think it's a A.R.E. 7030 tank into stock battery location. Pan must be A.R.E. 1007S. Rule book is clear and where.

djZ06

Well its definitely not my DD Z06, which some know. Its in my 69 camaro being set up for One lap, Optima and other shoot outs. Considering all the info Ive inquired on and received from this forum from geometry set up, engine, full c6 front and rear, full tube chassis and a lot of bling which isnt needed, most of the build is evolved around the corvette.

I spoke with Bill Dailey engineering today in regards to scavage pump volume and the extended lines to run to the rear. Bill also mentioned that they are coming out with a modified street friendly LS7 pan. Which is direct replacement and you can still keep your AC pump. Anticipated production release is about 2-3 months out.

You sure you're talking "T1" and not "ST" ? I just reviewed T1 rules again, along with the specific car spec lines for all Corvettes in T1, and I don't see where a dry sump system is allowed.

Touring class rules are here: http://cms.scca.com/documents/Club%2...orms/t-jan.pdf

9.1.10.D.1.f describes legal mods to the oiling system. Category spec lines for the cars (pages 12, 13 & 14) allows alternate pan & accusump, but no mention is made of alternate oil pump.

When you're saying "dry sump", are you actually referring to a true dry sump system (exterior-driven pump with scavenge & presssure sections) ?

Legal "dry sump" definition here, on page 143: http://cms.scca.com/documents/Club%2...ng.%20JAN-.pdf

Here's a true dry sump pan, for reference.


I'm not trying to be difficult. Licensed SCCA steward, racer & car builder...and I don't think what we know as "dry sump" systems are allowable in Touring class cars.

racecars as in tube framed GT1, TransAm type cars

Thanks for all the ruling info, saved me a lot of time looking up specific classes and definitions

Don Keefhardt

Wowzer...there it is. Finally got a paper copy, put on my reading glasses and there it was, waay at the bottom of the spec line. In the spec line, I saw the alternative GM oil pan and provisions for an accusump, but when it wandered off into wrapped tie-rod ends etc., I stopped reading. Shame on me.

Not a Touring class racer...my Corvette is a street car...I do my national-class racing in the SCCA "sports racer" classes, and run regionals & enduros in Prod, Spec-*.* and IT cars. But, as I used to be a "Showroom Stock" class guy ("Touring" classes came out of "Showroom Stock"), I'm really surprised that the CRB allowed a true dry sump in Touring. GT ? Gotta have it. ST ? Wild West for mods, so it's OK. Touring ? It goes against the stated class philosophy.

If I was a BMW or Viper guy, I'd be pissed. Since I'm not, I'll just scratch my head. I'll see a few of the CRB members this weekend, and I'm going it quiz them about it.

Wow, again.
