Pretty sweet

The dyno chart they have was indeed submitted by a customer... I saw it on a Honda forum, can't remember which one. I found it when I was browsing the forums at The Old One, home of Endyn (whose head helped develop the manifold).

Plus it looks so damn nice!

It's not just about looks, though. It frees up a lot of power.

Larry Widmer of Endyn has a crazy daily driver... '89 Civic Si with a destroked B16 (now 1.54L) that makes 480HP from 27psi of boost on 11.2:1 compression, from a Roots-type supercharger, no less! Sips fuel at 30mpg, too. :D

Though he doesn't use the AIR manifold on that (at least not yet).

Is this the correct dyno chart?

If so, how can hp be nearly double the amount of torque at 5,252 rpm?

That's nothing. There's a Golf in Germany(?) with a destroked Audi engine running 40+psi. :Q

Yeah well anybody can run mad amounts of boost with enough money. ;)

Vic there are 4 lines on that chart, all from the same car, each pair (HP and torque) from a certain manifold.

EDIT: I'll definitely admit the colors weren't chosen too well.

Still impressive though. I have yet to see a similarly boosted engine.

Yep. For the power-density guys, that little _streetable_ engine of his makes 312HP/L at the crank. That's not quite F1 territory (when they had FI) but still excellent nonetheless. :)

Trick looking manifold but it's just a crown. Everything el$e has to be in place.
Brake$, tire$, $u$pen$ion, cha$$i$, Tran$, axel$...etc.

Nice work though......:)

:Q man i'm a little pansy... crazy compression like that plus 27psi out of a little 4 banger scares me... :eek: :p

1450$..

That's quite a bit for simply an intake manifold. :p


I'd buy it.. if I was Jay Leno.

Hmmm... Good question...

V-TEC?

:D
Click to expand...
Nope. Mathematical law that applies to all gasoline and diesel IC engines. hp = (torque * rpm) / 5252 Makes it so hp and torque are always the same at 5,252 rpm. Torque should always be greater than hp below 5252 and hp should scale higher than torque above 5252.

Howard, I understand what you're saying but I don't see it. Maybe I'm totally wrong, but I think that dyno chart is bogus.

New V-Tec with mathematical law defying feature?

Dahlback Golf

450hp_per_liter

I also remember it having a motorcycle-like rev range that would put even Honda to shame.

Maybe we're just reading the wrong lines. I know that the values of HP and torque are supposed to be equal at 5252RPM.
