I wonder where the guy who built that site got his numbers for the density range of gasoline. I bothered to look it up in one of my books and got 7.4 lb/gal for premium unleaded (Forced Induction Performance Tuning by A. Graham Bell, 2002). When I checked the physics hypertextbook online I got 803 kg/m^3 and if I did my arithmetic right that converts to 6.7 lb/gal. Further investigation reveals that pump gasoline density has been changing as additive packages change to meet emission demands. I've also got some questions about BSFC assumptions that were made but right now I've got to go to class. Interesting topic Defiant!

Allan: Another factor to consider is Turbo motors have the reg referenced to boost and flow decreases above a certain fuel pressure so a 225l/min pump may not actually flow that on a turbo motor.

Here are some pics of my dry sump pan. It is a modified stock pan done by KEVKO, in Fairmont, MN. They did an excellent job :bigthumb:

IJ. LOL Allan!

Watching with interest!

7MGTEJoe Me too...

This is one of the most interesting 7M builds I've ever followed.

Thanks guys :)


Tank Location:
How about moving the battery? Or someplace in the nose like an intercooler. I change my mind on killing the PS, so the pan outlets are on the driver side. AC is on the chopping block....

Allan: Don't know if you can get the depth needed (tanks are usually long and thin to seperate the air from the oil that the scavenge stages suck in)
<edit> Might work if you cut a hole where the battery tray is and made the tank to hang through!

I like that idea

The tank is just about the only thing stopping me going dry sump!

If you mount it in the Hatch they're noisy as buggery so for a road car not good! (Before the peanut gallery jumps in with crap about standard road cars with dry sumps save it they're NOT running after market scavenge pumps)

Only other place it might fit would be up on the firewall where the charcoal canister is (well on a RHD car)

Some time ago I was called too the carpet for saying @ xxx compression is equal to xxx boost! I could not find the article again for anything in the world. This may not mean anything, but it bugged the crap out of me :icon_conf Anyway here is a link to a compression calculator.
http://www.turbofast.com.au/TFcompB.html Here I go agian..in the area of 17-18 psi the compression is 15:1 :icon_wink VE@85%

Here is something I did while on the MKIV side of SF. The question/debate does piston speed increase by stroke! The 3.4 Titan kit for the 2JZ was the deal in question.
