EVERY engine combination I've read about that was on their dyno put out way more power than I expected it to. I also agree that the dragstrip testing they do does not coincide with the power numbers they get off that dyno. I remember Steve Dulcich built a 440, think he called it the mild mannered mauler or something like that. I remember reading that article and thinking this is the last time I pay any attention to an engine buildup that's tested at that facility. CHIP

Fontanas air.....SUCKS!!!!!...compared to Bakersfield or Sacramento or Infineon here in Calif. I'm usually .2 slower at Fontucky than Famoso...

---

And I'm usually .2 slower at 75-80 than MIR, but my 600 HP engine in a 3700+ car runs 123+ even at 75-80.

Edit: 10/3/09 Results from 75-80

10.805 @ 123.55 / <No Weather #s>
10.756 @ 123.49 / 78*, 47%, 29.35"
10.754 @ 123.69 / 74*, 53%, 29.35"
10.786 @ 123.83 / 72*, 50%, 29.37"
10.860 @ 123.76 / <No Weather #s>

In the peak summer heat and humidity these would take a noticeable hit... at least another tenth off.

I'm in the Mid-Atlantic area where some of the tracks are pretty close to sea level (IIRC 75-80 is approx. 400 ft., where as MIR is something like 80 ft.). I have no idea how the atmospheric conditions vary across the country, although I'm sure even what I've listed above would be considered good for many tracks at higher elevations.

Until a combo runs a respectable MPH at the local track, you cant have bragging rights in my book...

I've seen some unbelievible dyno numbers published and never any track times to back them up.

Fontana is in an industrial area that has very poor oxygen content.

What I was able to find about the elevation is:

"The city's <Fontana> listed elevation, measured from the northeast corner of the intersection of Upland Avenue and Sierra Avenue, downtown by City Hall, is 1,237 feet (377 m). However, the highest elevation within the city limits is approximately 2,600 feet (792.48m), in the northernmost part of the Panorama neighborhood of Hunter's Ridge. The lowest point within the city limits is approximately 840 feet (256.03m), at the intersection of Etiwanda and Philadelphia avenues, the extreme southwestern corner of the city.[26] This difference in elevation is due to the southward slope of the Lytle Creek alluvial fan."

Where exactly the track is w/ respect to the info above I have no idea. It's definitely not Bandimere, but it's not MIR, either.

How about my chassis #`s.......485hp and 484tq to go [Email]9.98@3150lbs........Does[/Email] this jive?

. Also, those altitudes you posted don`t mean diddly squat due to the baro #`s and humidity and I`ve seen that track at 3500-4000+ feet..........

---

That was exactly the reason why I asked this in my opening post: "Can somebody who's raced at Fontana provide some actual temp, humidity & barometric pressure and / or density altitude #s for when they've been there?"

Sweet! I've been wondering if there was an online calculator just like that to use for my own data.
