Horsepower vs aero?

I'm reading this 500+ page puppy. Excellent so far. Will post a review on the "What are you Reading" thread. So far, I'm happy by page 50. But I love the cover photo.

Bikes have lousy aero to begin with.  Is that a turbo feeding into a turbo?

Gotta compress the air small enough to fit into the smaller turbo that compresses the air small enough to fit ino the engine.


The neat thing about turbos is they work on pressure ratios, not "boost".  To make the math simple a turbo at 15psi boost is 2:1 pressure ratio.  A turbo running at 2:1 feeding a turbo running at 2:1 is 4:1 pressure ratio, or 45psi boost (at sea level).


Of course it is not that simple, the real math involves efficiency factors and stuff that I've forgotten, but it's really easy to get 100-200 pounds of boost without spinning turbos hard.


Compound turbos is a neat subject, but what really gets me interested is twincharging.  You can have 30psi boost in the intake manifold, but only 15-20psi in the exhaust manifold, because half the assist is coming from the supercharger.  This is supposed to really help with detonation resistance because the cylinder scavenging becomes awesome.

Please.  If you are going excess,  go Dobbertin, or go home. Twin turbos feeding twin Magnuson superchargers on a nitrous fed aluminum small block Chevy

My favorite thing about that J2000 is the (lack of) rear suspension.

While you're trying to assimilate this visual assault, tech details begin to burn through. You realize the only way Rick could stuff those leviathan Firestones under the back of the diminutive J-car was to eliminate—wait for it—the rear suspension. There are no shocks and no springs. At its coming-out party, the J2000 relied strictly on sidewall deflection to tune ride quality. And, yes, given the right circumstances, it would bounce like a Top Fuel car. Later, Dobbertin added a pair of valvesprings(!) between the top of the rear-end housing and the chassis to dampen the legion of critics who howled that any car without a rear suspension was not a real street car.

Obligatory picture:

Started my 2015 V60 yesterday morning and it was a bit slow to turn over.  Stopped for coffee and it wouldn't start again.  Called my neighbor who ran down to me with one of these.  It started the car three times yesterday and once this morning instantly.  Amazing small compact and light at just over 2lb's.  I've now ordered my own, but yes I'm going to replace the batter today as well.  Only $99 from Amazon.

Oy.    This poor 1993 'Vette has been on my neighbor's lawn for 5 or 6 years now.  I offered to push it into my garage and find out why it has no spark because that's just sad.  Saw him yesterday, reiterated the offer, "Thanks, but I just sold it".  Wifey was there "WHAT?"   Yeah, I was going to tell you.....

"Good,, I hate that thing!"  Seems a Fed-Ex guy from Connecticut working in the area stopped and made an offer.  $2k.   GONE!


Oooo.... Coulda been a Challenger!

My little sister got this from the shelter about 5 years ago. 

her name is Kitty, and she's fat. And has a huge tongue. 

Not sure why, but I think this is my favorite dog ever. Thought y'all should know. Quiet, smart. Best fetch dog in the world. She'll run herself to death to get the ball. 
Fat, tongue:
