Guest Kidneyboy Posted June 21, 2008 Report Share Posted June 21, 2008 Im working on a SC project for my little bimmer. Does anyone know where i can buy sheet stock alloys? Some aluminum, 1/4" thick, and 3/8" or 1/2" for flanges, 1/4" nominal sizes in feet [4X4 should cove it] . Somewhere local to Cbus would be nice, but i dont mind driving a distance for a good deal.

craig71188 Posted June 22, 2008 Report Share Posted June 22, 2008 I've always used Research Alloys - south off Goodale across from the old Big Bear headquarters. He does scrap, but has all kinds of aluminum "drops" and cut pieces that he sells per pound regardless of alloy type. He's always done me right over the years.

MeadEngineering Posted June 22, 2008 Report Share Posted June 22, 2008 +1 for R.A. But of you want new let me know I can get it Quote Link to comment Share on other sites More sharing options...
Science Abuse Posted June 24, 2008 Report Share Posted June 24, 2008 1/4"? 3/8!? 1/2"!? Do you want it to support the weight of the car? Stuff that thick is usually called "plate", not sheet. What are you using it for? I've heard good things about RA, but I also find some good stuff on Ebay. Shops sell cut-offs and surplus.

Guest Kidneyboy Posted June 25, 2008 Report Share Posted June 25, 2008 1/2" for flanges. that and if anyone has scrap im not going to turn away a good deal Im making a manifold for a little 4 banger that will have a water to air intercooler built in and needs to be able to support an eaton m90. im pretty sure i will be making some steel bracing for the weight. Frankly, im not sure what thickness i should go for. Im not going to be running insane amounts of boost [5-8] any suggestions? Quote Link to comment Share on other sites More sharing options...

Guest Kidneyboy Posted June 25, 2008 Report Share Posted June 25, 2008 Came across one for $100 with 50k plus some extras. Downing Atlanta made a kit for the same engine some years back that used an eaton M62 SC. the M62 is a bit more difficult to find, and since the M90 came on so many production cars it brings the cost down.

Science Abuse Posted June 25, 2008 Report Share Posted June 25, 2008 You may be overkilling, but I'd need to see your aplication and arangement. There's no reason that 1/8" material cant hold 2 Bar if it's welded right. Brakets for the blower should be sturdy, but 1/4" 6000 aluminum should be more than enough. Going with 1/2 is sure to tbe strong enough, but you're getting more expensive material than you need, and taking on more weight than is neccesary. You should have no trouble with 1/4" for your flanges, as well, as long and they're flat and you've got good bolt coverage . Quote Link to comment Share on other sites More sharing options...
Guest Kidneyboy Posted June 25, 2008 Report Share Posted June 25, 2008 Good deal! Thank you Mr. Science Quote Link to comment Share on other sites More sharing options...
Guest Kidneyboy Posted June 26, 2008 Report Share Posted June 26, 2008 Funny you should ask about the M90. Well, for it not to ruin my motor with 20+psi i would have to run it at no more then ~8000rpm which is not very efficient for the blower. In other words: i need a smalled blower Quote Link to comment Share on other sites More sharing options...
Science Abuse Posted June 26, 2008 Report Share Posted June 26, 2008 Mercedes has an Eaton for you! AKA Der Kompressor. IIRC the Mazda Millenia uses a compact unit, too. Given your motor and what you're doing, I would be avoiding roots blowers all together. Too much parasitic loss, you'll be loosing 30% of everything you make. See if you can find a small centrifugal blower, or a DSM turbo. Quote Link to comment Share on other sites More sharing options...
Guest Kidneyboy Posted June 26, 2008 Report Share Posted June 26, 2008 I like the idea behind a roots blower since its more linear than other types and will allow for low end torque. the car i have now is used for Autocross and DD duties. Roots blowers should work wonders for the little thing. I was also considering changing the displacement of the engine before SC it. Which will work with boost and help keep the blower RPM up. If i bore/stroke it out to a 2.1L the blower will be in its efficiency range at 8psi. Quote Link to comment Share on other sites More sharing options...
