Thanks in advance for the help...

Basically I am working on a forged 355 LT1 (for a single turbo setup) and I have for it a drag race 8 qt. drag pan from Billet Fabrication (www.billetfab.com)

The person who sold me the shortblock gave me a Melling HV Standard Pressure oil pump (P/N 10555c) it flows 25% more than stock.

Is this a good pump for my application? Also I have read from searching that some people recommend having aftermarket oil pumps blueprinted? Is this necessary?

Also I would like to know what oil pump pickup I should use with this pump? I know it is a 3/4" inlet diameter but I am having trouble finding exactly which pickup I should get from summit racing. Do you recommend getting a bolt-on pickup or a press-in?? Also preferably should I measure the depth of the pan to know what length of the pickup I need??

One more thing, since the block is half filled, the person who sold me the motor also recommended running an aftermarket oil cooler... So I think I found the oil cooler adapter that I can screw on before the oil filter:

So now if I just need the lines and the actual oil cooler, would a kit like this have everything I need?

Thanks again

 

Whatever pickup you get, you ALWAYS tack-weld it to the pump.

You may want to contact the manufacturer of the oil pan to see what kind of pickup they recommend. The pickup depends more on the pan than the pump, so they should be able to steer you in the right direction.

That pump would not be my first choice. It is a high volume pump (25% more than stock) - completely unnecessary. I would use the popular 10554 - it's standard volume/high pressure.

Not sure on the oil cooler question though. Maybe try the FI forum?

 

I've always heard high volume oil pumps were bad news on lt1s.

 

Dennis, on a stock LT1 with stock pan you would be right it seems like HV pumps are known to starve the pan of oil, but on aftermarket high-capacity oil pans they are ok.

Joe, good idea I will contact the oil pan manufacturer for advice too about the pickup and pump. According to the specs on summit racing the 10554 is a standard volume, standard pressure pump though... Although you can probably put in a high pressure spring IIRC from searching, should I do this instead??

 

The concern with the HV pumps is that they take more power to turn and put unnecessary strain on the oil pump drive gear. This (more often than not) causes the gear to strip. Unless you have unusually loose bearing clearances the HV pump is unnecessary.

IIRC, the 10554 comes with the Melling pink spring, identical to the GM white spring, which is 70#. Higher pressure is okay, higher volume, not so much. Another bonus is that the 10554 comes with a hardened drive shaft and metal coupler.

 

Ok well I just spoke to a tech at Billet fabrication... He recommended I get a Titan Sportsman series oil pump for my pan with the pickup. I'm sure they're good products but problem is it's a 600$ oil pump/pickup He did also tell me though that high volume pump is not necessary.


Joe Maybe I'll just get the Melling 10554 as you say if it will work... What pickup do you think I'll need? How far from the bottom does it have to be installed?

The pan is a high capacity 8qt. pan... it's 8.5" deep here is a pic:



Will something like this work?

It says it's for 8.5" pan, 3/4" inlet tube diameter

 

Also I was wondering do you guys think this pan will clear stock K-member? The person who sold me the pan said it would but I don't know it looks pretty bulky. Do most ppl who run canton or other high-capacity pans are they able to fit with the stock k-member?

 

I don't know about the k-member but my concern with that pan would be ground clearance. That looks as though it might be a problem with ordinary things like speed bumps, curbs, etc. Any time your first point of contact under the car is the oil pan, you have the potential for disaster.

Billet Fabrication turns out some impressive parts. I had a set of Jeff Johnston's valve covers on one of my race cars back when he was working out of Simi Valley, California. He has advertised Titan Oil Pumps for years. I think there is a business connection there.

What are the demands placed on the oiling system by the turbo? I'd say that additional lubrication demand would play a part in your choice of oil pumps and pickups. I would never run a high volume or high pressure pump on a small block unless you intend to place some extraordinary demands on the motor and you have the rest of the equipment needed to handle those demands.

Set the pickup depth about 1/4" off the bottom of the pan. If you're mocking it up to measure, don't forget to calculate the thickness of the oil pan gasket. Have the pickup tack-welded in one or two spots to the pump. Remove the relief spring from the pump before welding. Do not weld it all the way around the connection. I recommend tack welding as well as the bolt-on feature. This one time when double protection is a good idea. I recently removed a pan and found the screen portion of the pickup broken off, laying in the bottom of the pan. We didn't lose the motor but it was a hand grenade minus the pin!

Good luck,

What about using a HV pump on a forged 383. LE3 heads and cam, roller, 4 bolt splayed caps, etc.

 

See post #5.

 

High volume oil pump really requires a larger capacity oil pan such as Canton,moroso,milodon

 

Oops droid double post

 

Well I will be running a single Precision 88mm turbo and will be looking to make at least 800hp. We are going to tap into the oil pan for the turbo, and as I mentioned above I will be running an oil cooler as well.

Thanks for the help C some great info in your post above.

 

Well **** I already put one in my 383 but the motor is not in the car yet, should I replace it or let it go. It was just a HV pump from advanced

 

I have absolutely no experience with turbos. Hell, I don't even know enough metric measurements to gauge an "88mm turbo." But, if it makes 800 horsepower it must be of a decent size. With projected outputs such as that, I would suggest that you want the best oiling system you can get. Elicit advice from the turbo manufacturer regarding the pressure and volume needs of that system. Do whatever it takes to exceed those needs by a comfortable margin.

On Super Stock motors that see RPM ranges at 8000 and above, I recommend that serious builders consider an oil accumulator system. I know that Canton makes a system but I usually suggest a #23900 Moroso system for the cars that I work on. That places an extra quantity of oil in reserve in the system that only comes into play if the normal pressure drops below a preset level so the oil level in the pan is kept at a normal level. It can also be used to "pre-lube" the entire motor before it is fired. Jeg's has a description of how it works on their website: <http://www.jegs.com/i/Moroso/710/23900/10002/-1>

Good luck,
