Kevlar, your car has me inspired. I've been looking at it for months.
My retirement project was going to be a tube chassis kit car, probably a Becks Spyder, but I like the look of your car so much, I might actually use the look for my own version. Probably Swift GT powered, of course.
Thanks Mike,I think the 13b would make an excellant choice for a road based home built-with boost of course.
Back to the shop,the "other" pretty much home built car needs to get finished-ice racing starts next weekend and I have so much to do.

I think you hit it there, bud. Welcome to GRM.Just to lend some perspective here, the new 2012 Indycar will weigh about 1380 pounds total, of which at least 212 pounds will be in the motor (rumor has it that the current motors in testing are closer to 250). The new motors (2.2L) are supposed to be making about 575 hp.
Now... without getting into the typical flame wars that have surrounded Indycar for decades (or being accused of being off-topic on my first post here), let me suggest that perhaps trying for sub-1000 pounds with car motors (assuming 200 hp or more?) is a great engineering exercise, perhaps it won't be "locost" and maybe just a bit much for a fun drive?

I think the assumption that you'd need 200 out of a car motor is a bit on the high side. You don't need that much power to make 'em work. We have the DP-modified V8 Atom in town, and he's almost exactly as fast around our local track as Brandon in his R1-powered sub-1000 lb Locost - and the Atom has Hoosiers versus Nittos on the Locost.

Ah- you shouldn't be so modest- it was your (much heavier) car that Burt Levy compared favorably to a supercharged (300 claimed HP) Atom if I recall correctly?
And yours put down ~140 to the wheels if I recall?

Yeah, my 1250 lb car with 148 hp at the wheels was better than a supercharged "300 hp" Atom according to Burt. Faster, too. But he also noted at the Atom was fresh out of the box and not set up properly, and it turns out that "300 hp" in Atom-speak means about 225. The DP V8 car was properly sorted, which is why it's a better comparison.

Hey guys, I had been looking into a lowcost type car before I picked up my current project. way back on page 3 some guys were talking about subaru engines. This is what I'm putting in the back of my project so I thought I'd offer some info. the block is right at 30 inches wide, so I don't know how that would fit in the front of one of these. Howerver, the transmission options are wide open. Especially if you wanted to do a mid engine car. Look into the high end sand rail world and tons of those guys run subaru's mid engine bolted up to a vw, porsche or mendeola transaxle. they are cheap cheap hp. Right now you can get a twin turbo ej20 for $600.
