Which Peterson tank for LS7?

[badazz81z28]

Need one for a 70 camaro. Not sure on the size needed or where to put it. Looking for ideas. Thank you

[raustinss]

Some guys have tossed them in the "tulip" panel, behind firewall , fender side of dash areas...mark steilow did it cut it in and made it look pretty nice , now he was using a later larger model gm tank thou

[badazz81z28]

I can't seem to find any pictures out there if second d gens...really could use some help

[raustinss]

I can't say which tank to run but , run one that A holds the right amount of oil B you can possibly fit ... in the area I suggested ...otherwise you could possibly work something behind the headlight in front of the front tire . Lol or jam it in front of the rad lol

[badazz81z28]

Nobody else?

I don't think you are going to find a lot of people who have built the combination you are looking for... I know one of second gen that mounted a tank behind the passenger side headlight. You have to cut a hold in the inner fender and come up with a way to mount it. You also want to protect the bottom of it in some way.

At the firewall, I determined I couldn't use more than a 2g tank comfortably in a cylinder configuration when mounted to the firewall. There isn't enough height above the frame rail and with enough header clearance.

I ended up having a custom tank made by Stef's. This was after mocking up a shape that gave me the most volume and fit in my space. I think Finch used a 2.5G tank in that space. There are some pictures either on FB or one of the forums somewhere, but not a lot.

.z^^ do you have pics of your set-up?

[carbuff]

You are welcome to poke through my photobucket library. I don't have any finalized pics in there, but it's easier to see before I powder coated it black anyway...

I can't believe I can't find example on a sec gen

You're looking for something bolt in, it doesn't exist. I would be surprised if there's a dozen 2nd gens around with dry sumps that aren't all out race cars. It doesn't make sense for a company to produce a bolt in solution for such a low volume application. There's not even a good bolt in solution for C5 Corvette's which is a larger market. You're going to have to either have a tank built or modify your car to use an available universal tank. Using the tank that Bryan had Steff's build is likely the path of least resistance. You ideally want at least 2.5 gallons minimum with the LS7 pump system if you want it to live for road course use.

You ideally want at least 2.5 gallons minimum with the LS7 pump system if you want it to live for road course use. That's good advice. Stock LS7s run out of oil on long left hand sweepers. Serious C6 guys ditch the factory "dry sump" for something better like this (http://www.drysump.com/ls7.htm), or even better, like this (http://aviaid.com/pdfs/153-boltin_dry_sump_lubrication_systems_for_ls7_engine _and_zo6_corvette.pdf).

I did the latter after blowing up mine.

If you're just building a cruiser or an occasional mild track day car, the factory system is adequate, though you should over fill the engine by a quart or so when you do go on track.

[badazz81z28]

I figured something custom had to be made, looking to steal an idea of what people already had done. I'm keeping the stock pan, just to figure out which tank and where to put it,

[badazz81z28]

What are y'all thoughts on putting it where the stock battery was? I could figure out a bracket to support the bottom, something on the core support and cutting a hold in the inner fender?

[dhutton]

Interesting tank placement here:

[badazz81z28]

^^ not too bad, do you know how it's mounted?

[badazz81z28]

I'm thinking here

[raustinss]

Funny enough thats where I suggested ...and btw thought of you one the gentleman selling the tanks that you responded to ...hopefully you get one that works for you

[carbuff]

My fabricator did a second gen Camaro and put it where the battery was. He used a 2.5G tank. It's taller than you realize, and he was concerned about the possibility of something hitting it from the bottom. So he built a 'cage' under it to protect the bottom. I don't have details or pictures, but I do recall considering that area and thinking it was dangerous and hard to fit the size tank I wanted. The Firebird inner fender is a bit different than the Camaro, so perhaps the Camaro will be easier to fit something in that space.

Personally as I thought about it, I didn't want the weight that far forward either. And even when I decided to go custom, I couldn't fit a tank in that space very well that was 3G or more without some surgery that I didn't want to do. I also have downbars and my AC condenser in that area to contend with.

[badazz81z28]

I agree, the battery location probably ain't ideal, but what other choice do I have? I'm open to ideas...that won't require me to pay someone $100 per hour to do. I would like to have it just like Tim, but DSE won't make me a bracket.

The tank I originally had is modified on the bottom and too small (only 2 gallons). The tank that Bryan had Steffs make is going to be the easiest solution but I would change the way he did the breather, I would have three -12 fittings added to the side, run one to a breather can and run the other two to each valve cover.

[badazz81z28]

^^^ did you swap your original tank out? Is it in the same location?

The original tank has been gone for 3 years.
I had a tank custom built to fit up near the firewall to move the weight back and to add more capacity.

Wow! What did you do with the old bracket???

Interesting that you point out the breather setup... I've been debating whether I want or need to add a catch can to my system to alleviate any potential crankcase pressure. I really don't think that I do, as I expect the Dailey pump should pull any pressure out and pass it out of the breather (I see puffs of smoke out of it from time to time, so I know something is coming out).

Tim, do you have any thoughts on whether a catch can is needed on our setups, since ours are similar? Yours can pull way more vacuum than mine can, but I would think mine would evacuate any pressure that might build up in side the engine... Agreed?

Tim,

Is that hose on the bottom your supply point? If so, do you have an internal tube that goes to the bottom to pickup oil from the very bottom of the tank with suction?

[71RS/SS396]

I have it around somewhere, but I have no idea where that is. You cannot fit a tank with enough capacity where I had my old tank, I tried.


Tim,

Yes and yes.
On the 3 stage you have, we usually run a -12 from one valve cover to the breather can and a -4 or -6 from the other valve cover to the oil tank just to circulate the air to keep moisture from collecting in the covers and the top of the tank.

^^ I bought the Peterson LS7 tank. I'll have to get creative when I have more time to wait for a custom tank. . My car is also not in the same league so probably not too critical for me right now. I sure would like to buy your bracket or atleast some measurements. Are your old tank mounting clamps for sale?

I have no idea where that stuff is, I have floor to ceiling pallet racking filled with boxes of parts...it's somewhere in that stuff. I don't have the spare time to go digging through all of that stuff to look for it.
That Peterson tank is too small, you better stay off the road courses with that tank, you'll suck it dry after a few laps. You're going to have to notch the bottom of that tank if you put it where I had my old one.

[Kcorrigan2]

Listen to Tim, he knows what he is talking about. I run a 3 gallon Peterson tank in the trunk because there is simply no room under the hood to place a stock tank with wide tires and everything else....also improved weight distribution but that place,net has its own issues. Dry sumps are awesome but can cause more problems if not properly sized and plumbed.

[badazz81z28]

The alternative was the wet sump conversion. That has a much smaller capacity...does the LS7 pump just that much more powerful then the LS3? I'm confused how I can run a LS1 with a 4 quart pan and be fine but the LS7 with 8 quarts but be in trouble?

[dontlifttoshift]

Just like everything else, there is no right answer for _every_ situation.

I have a customer with the Peterson LS7 tank mounted where the battery was on a 1st gen. This will be his 5th season on the car with a Mast 416 and a ARE pan. It hasn't blowed up or run out of oil but he doesn't run at big dog tracks like VIR or Daytona either. He doesn't see the situation where the car is holding 1.2g lateral for 4 or 5 seconds at 6500 rpm or more. In his case, 8 qts of oil is more than enough. Tim has proven that it doesn't work for him.
