Was going to install vacuum pump instead of evac tubes or would switching to dry sump setup be better option. Engine is in pulling truck 470 with iron-1 heads around 750hp a run last around 25 sec at 7000-8000 rpm . wet sump external lines keeps good psi currently. thanks for input

Dry sump is more Gucci.

A good vacuum pump system is 1000.00 a good dry sump system is 5000.00

if all you are trying to do is pull vacuum in the motor the the 1 grand deal is the way to go.

If you want a oiling system that don't suck the dry sump system is the way to go.

either way turn your main seal around (put it in backwards) you will get more vacuum.

There are a lot of advantages to a dry sump system. Especially in a pulling truck where you have a ton of room around the engine for the lines and tank. If you have the money for the pump and pan I'd highly recommend the dry sump system. The bearings will thank you.

This is what I'm talking about

A dry sump system can be put together fairly cheaply if a person buys used parts. I did a low buck dry sump system for my 505 motor for less than $1000. I used an older 3 stage pump from a circle track car, a deep wet sump pan and a used tank. I had to fabricate a couple of parts and buy hoses. It worked great and didn't cost much at all. The tech article on my website shows a little more detail. www.arengineering.com

Dry sump is better all the way around... but the cost...
you can get one for about $3500... CV Product sell mostly
roundy round stuff but that where I bought mine...
I also made most of the stuff like the tank and pan

peterson r4 pump = 1800.00
peterson tank = 680.00
peterson 400 filter = 200.00
drive system = 500.00
lines and fittings =1000.00
charlies pan = 600.00
plus shipping and tax and you have a good system

You can not use a wet sump pan and turn it into a dry sump pan by simply sawing holes in the side and adding fittings.

look in a good DRY SUMP pan and you will see the the difference,you are not just sucking oil off the bottom of the pan they call them scavenge sections for a reason.

people sell used parts for a reason, buy those used up things and wander why they need a vacuum pump on top of a dry sump pump to make vacuum.You should be able to pull 18 inches of vacuum with a good drysump pump and NO VAC PUMP if not its at the end of its life or it was junk in the first place,If you are going to half a$$ a dry sump system you would be better off using a good wet sump system.

Actually the wet sump pan worked okay in our testing. And the low dollar used pump off of a circle track car also worked okay. That setup wasn't strong enough to pull a lot of vacuum, but it ran just fine as a dry sump.

Depending on how well its sealed and the number of
suction sections will determine how much it will pull
on the vac.. with mine I can get 13"hg with just the
pump... which is plenty of vac

Yes this is not my first rodeo or dry sump syetem I have had them long enough to where them out.The peterson is the one that works the best(schavenges correctly) I just dont see why you would mess with it if it was not at its full potential.I know to buy a pump that is sized (number of stages)correctly to get proper vacuum but the first timers dont, thats why its important to talk to the makers of dry sump pumps when you are green so you dont build a bomb.

just because it sucks and blowes doesen't make it a good hooker

This will be a winter upgrade so im in no rush the fab part is not a problem budget is not unlimited but i have been down the road of not doing it right the first time and ends up costing more to get right the thought is instead of spending on a vacuum pump setup and then down the road needing to upgrade to a dry system and have wasted money on vacuum. What do you use to know how many stages/scavenge and presure out

For a pulling truck where you have plenty of ground clearance it would make sense to use a deep pan rather than the typical shallow dry sump pan. I posted the picture above where we used a deep wet sump pan for a dry sump system and that worked great in our application. It would also work on a truck puller. But most wet sump pans are only going to accept two pickups so that is a limitation. If you're going to go with a 4 stage or 5 stage pump then you'll need a custom built, deep full length pan.

If you're going to get a custom pan you might as well make it as deep as your chassis will allow. Most of the dry sump pans on the market are designed for circle track use. What you're doing is different than that so you don't need to follow what those guys do.

Peterson does make really nice stuff, but they don't have Mopar specific parts. We make the block plates and drive plates for Mopar engines as well as distributor plugs and a few other items. www.arengineering.com then click on dry sump.

Hey Andy how many passes were made on the motor that you made the dry sump for?
