100% correct. From what i've found out, our Mopar engines make the best HP
around 180-185 degrees. Anything colder than 170 and the HP starts to fall off
and (obviously) anything above 195 is about the same drop.

> In 1998, PFM teamed up with Viper car racer Gary Bethurem to integrate PFM's
> long history of race boat technology and Bethurem's desire to make his
> racecar go faster. After patenting the new PreChiller, PFM president John
> Pelkey and Bethurem set out to make the finest auto pre-cooler system by
> creating the ultimate challenge for themselves. They believed that if they
> could make the PreChiller work in a large engine racecar, they could adapt
> it easily to production vehicles. In St. Louis last week, two years of
> dedicated effort was rewarded when Bethurem's Viper performed with dramatic
> results. Each and every trip down the drag strip, the car ran quicker than
> any comparably equipped car. Even more impressive were the Dyno (Mustang
> Dynamometer) test results performed at Paxton Automotive this week in
> Ventura County, California using Bethurem's modified racecar and a stock
> Viper RT.
>
> So impressive were these results that Bethurem was invited to show the
> PreChiller to Hot Rod magazine, sr. editor, Ro McGonegal and publisher, Brad
> Gerber, who will review the PreChiller in Hot Rod's upcoming issue. Says
> Bethurem, "If we can show this kind of radical difference in horsepower in a
> large engine race car, just think of what the PreChiller will do for the
> family vehicle whether it's a car, truck, SUV or RV". Pelkey adds, "in an
> era of record gas prices the PreChiller will improve any vehicles engine
> performance dramatically by adding colder and denser air", and "in fact the
> PreChiller should reduce air polluting emissions which are so damaging to
> our environment."
>
> PFM plans to launch the PreChiller through the Viper car community so that
> it can take advantage of existing molds and because current demand is
> substantially higher than the availability. PFM manufacturing manager, Ryan
> Pelkey says the company is ramping up for production on availability and
> other models but suggests that it won't happen overnight as the company
> wishes "to continue on its path of perfection, not mass production".
