Last pictures of the engine bay ...



Still need to make a hose for my BOV (need a straight -4AN and a 120* bend -4AN pair of hose ends to build it), do something with the two air nipples hanging off the back of the intercooler that were originally for the stock ABSV and ASV (probably pull them out and weld a small plate over the area to cover the holes), and put another 500mi or so on the engine to get it broken in.



Running well, otherwise. I'm happy w/ how it turned out.

damn brain nice work congrats on every thing. i read ur whole AI thread and was very intrigued and cant wait for future exploration of the use of methanol. i think it was awesome of u to write that whole blog and take the time to organize and lay out all the steps as u were still experimenting with with everything. cant wait for more research on everything thank you for keeping us all posted on everything. i will be contacting you with in the next few months to have some work done. awesome job

hey i've notice some people using this .why.what is the purpose of if is it like a baful<i think i spelled this wrong<

 

dam bro your engine looks good

 

it is a baffle. its used to stop the oil in the pan from sloshing around, some also say it suppresses engine flex

 

+1 for the first part; Lynn could probably chime in and explain in better detail what else it does.



As far as engine flexing, I highly doubt that thin sheet aluminum can do that.

Thanks!!!

I highly doubt the baffle will stop the oil from slooshing around, it's mounted between the block and pan, not in the sump itself.



When oil exits the irons i usually will just plummet right into the sump, that generates bubbles in the oil which sucks in many ways when you need to suck it up into the oilpump.

What the baffle does, is slow the oil down and lets it aeriate(sp) before it gets to the sump.

 

The idea of the baffle in racing is to help re move foam from the oil before it drops into the pan. To keep the oil pickup covered with oil no matter the dynamic situation of the chassis. And to keep the entire oil supply from filling the front case under hard braking.



In my case I just had a 3" by 5" hole under the center iron drainback hole. Even the pickup had holes for oil and the two mounting bolts. Never an oil problem or pressure surge even before the dry sump was added. Run the oil level about 1/4" above the baffle for hard cornering and braking, as in auto cross and similar racing. Fine for road racing as well.
