Hello,
A friend just purchased Bob Anderson's ESP camaro. It's a 1994 Z28. Bob had a shop rebuild the motor and had a high volume oil pump installed. Now there is a momentary drop in oil pressure when you are on the breaks very hard (racing hard). The Lt1 still has the factory oil pan. The oil pressure problem needs to be fixed before it goes back racing.


My current thought is that since we need to drop the K member to get at the pump or the pan, we might as well just put in a racing pan and reset the height of the oil pump. It looks like the Moroso pan and pick up tube are the way to go. Here is the pan: http://spideraccessories.stores.yahoo.net/moroso20185.html

What do you guys think?

Are their any tricks to dropping the K member? It looks fairly straight forward.

Thanks,
Chris Shay

Does anyone have any comments on the stock vs. high volume oil pump? "ESPCamaro" said the stock pump is the way to go.

So is it common knowledge that the stock volume pump is required? Is the high volume pump OK when used with an aftermarket pan?


Thanks,

No man ditch the high volume pump. It's a monkey see monkey do thing-why everyone uses them.

High VOLUME means just that. The pump pumps more oil. Not necesarily at a higher pressure. You do TWO things. Lose power by parasitic drag (and as you know we are VERY limited on what we can do) and you pump oil to the top of the engine faster than it can drain back.....

Stick with either a stock pump or stock pump with high pressure spring......

You don't want a street strip pan you want a road race pan. If you have the time it might be worth it to fit a REAL crank scraper to. The Canton pan has a wannabee scraper built in but not the same thing.
