interesting how the motor sits flat, and not on the usual lean, why would it be dry sumped as well? For easier fitment or other reasons?

at a guess one reason to stand it up would be to give more room on the exhaust side for the turbo setup and another maybe beacause it runs a different box, possaiblily an auto. dry sump is a good idea on high output motors and it appares he may use it for circut racing

Dry sumping guarantees an oil supply to the engine.

Even with good baffling, in extreme cases, the oil pickup can suck air for a brief moment, and in a high revving motor this will spell death, eventually if not immediately.

Oil splashing around in a sump and onto the crank will also suck a small amount of energy from the motor... not what any power hungry racer wants!

With dry sumping you also normally run more oil so it is not working as hard because of increased volume, and the system generally keeps the oil cooler by routing the oil through coolers and through long lines to (normally) the rear of the car.

Also, by placing the oil reservoir in the rear of the car, and scavenging oil out of the motor, you are also removing weight from the front of the car and placing it at the rear, which all helps achieve what most racecars strive for.. a 50-50 weight distribution over the axles..

All good reasons... :thumb:

When you have to stand the motor up to clear those snails, you're looking at a serious engine. I'd be interested to know what gearbox is behind it. With dry sump the engine pulls vacuum in the crankcase which helps with the rings sealing and at 6-8500 there is no windage on the crank [gain is usually about 30 hp on a v8] in circuit cars [for example mine] at 1.4G's of cornering, there is an oil starvation problem [Dry sumping can get expensive,mine cost $10k. oil changes at $85.00 for a take home pack of full synthetic x 16 litres =$340.00]

How cheap do you think you could possibly dry sump an engine. Something like an F20C. S2000.

Nothing too flash though

$2500-$3000 could build a basic system [3 stage without a heat exchanger , scavenge filters,or remote HP6 filter

The cheapest way would be to pick-up a complete sprintcar set up for a chevy [try ebay] Make your own pan,& try & adapt the drive,& use as much plumbing as you can from what you've got.[i've seen this done before,on a 24valve Toyota in a RX7]
