Dry Sump system how much power gain

I decided to put a dry sump oil system on my 14 degree big chief 622. What kind of power do you think the dry sump will gain. I have heard between 30 to 50 hp.

Interestingly, or not, I have a Corvette with a manual transmission and dry sump oiling. The automatics came with wet sump oiling. While GM is eager to take credit for a 6 hp gain for the optional exhaust, they make no claim of hp gain between the wet and dry sump offerings???

No appreciable power gain from just installing a dry sump. Gains will be in better vacuum control, which will make some more power. Gains will be in consistent oiling with a large stroke, decreased windage, nickles and dimes in a pan with a large kickout (windage) , ability to prime the engine.

I’ve seen a dragster pick up a tenth...

In general you will see an HP gain on the dyno with a dry sump vs wet sump w/a vac pump but on track usually noting as the added power is offset by the added weight of the dry sump system. If you pick up anything worth while, likely you had an issue to start with or never used a vac pump with the wet sump. The larger the stroke in a motor, the more potential HP gain there is due to less windage with a large crank and rods plowing through it.

Too many rabbit holes to chase when you talk about optimizing your oiling systems for HP gain, to generalize or put a number on the expectations.

I don't know if I gained any power or not, likely did, but I do have solid oil pressure in the shutdown area!!!!

Drain 2 quarts out of a 8 quart pan and see what the gain is ET wise. Maybe not horsepower on the dyno but ET. I tried it for one pass on my 632 and picked up almost a tenth because I thought about going dry sump and with that experiment I’d say worth the money. So I’ll say with no oil in the pan you’ll gain a little over a tenth if that’s all you change. This was with a moroso Aluminum pan. If you have a high dollar pan to control the oil you may not gain much

IHRA had to institute a minimum oil level rule in Top Stock class.... Wink

The only time not swinging a crank thru oil is a disadvantage, is when there isn't any oil. No one in their right mind would say that a dry sump isn't an advantage. Is it worth the cost in your case? Only you can decide.

I’ll say I bit the bullet on my 421 Sbc and adding the dry sump for 3 reasons. 1 being a little Et gain 2 being the engine has to be more consistent with the crank not having all the oil thrown around and the other is not loosing oil psi in the shutdown. Is it worth the 4,500 for everything maybe not to some but for me it is. As far as weight gain from the dry sump I’m adding maybe 10 lbs to the car. Removing the vacuum pump will equal out with the dry sump pump, adding the primer and remote filter will be about the same weight as the wet sump pump. So I’m adding the weight of the tank (5 lbs 6 qt tank) and the hoses and extra fittings.

Guys thanks for the feedback. I decided to put the system on. I have already received everything from Moroso. I am excited to have the oil pressure in the shut down. Also we will see what et it gains.
