2023 HPL Open House

[wwillson]

They're over 100% VE at 10,500 rpm. They 120-130% VE around peak torque at 8500-9500 rpm.

At 200MPH?

I don't think any n/a engine is capable of at or over 100% VE.
Forced induction is different, but this is a n/a engine.
There is some ram effect at high speeds, I'll admit, but I doubt it goes over 100%.
If someone has true data from a mass air flow meter then I'd have to defer to that.

Regardless; it's moving a lot of air!

 

[wwillson]

~25.5 ft^3/s or ~2 lbs/s of air

2 lbs/s is a lot of air. Just a factoid, the 777X GE9X engines each ingest 1,500lbs/second at takeoff power.

At 200MPH?

Still on the dyno. Short ramming / harmonics is extensively optimized. Intake runner and header primary lengths and diameters are optimized, along with valve event timing, to maximize scavenging and cylinder fill, creating a "supercharging" effect on the back half of the intake cycle.

I had a very good time there this weekend and it was nice to have met some of you

Now, since nobody has told me my car isn't Pro Stock LOL... I am an HPL fanboy, yes, and I support the company. I got this!

I do hear @michaelluscher wants my HPL oil drum. It presently sits in my garage, as per the picture!

It was one week ago I was on the road to here! I LOVE road trips!

And I got to see @wwillson 's Durango that uses HPL as well!!

Chances of me attending a HPL open house out of state are hovering between slim and none. And Slim just left town.

I have to fight just to have a vacation than anything other than the beach, which is what the rest of the fam always wants to do. I grew up in Oregon and I love the mountains, the beach is just meh for me. Oh well happy wife happy life.
