Density Altitude Calculator

By Jennifer on September 17th, 2018 in Info and Education, Main News

In addition to our race track weather pages, we also have a free online density altitude calculator. Our DA calculator provides air density, grains, and vapor pressure too.

Check it out: density altitude calculator

On that same page is an elevation calculator if you need it for your location. We are currently researching other calculators we can offer on that page as well.

Check out this Racer Run

By Jennifer on September 10th, 2018 in Features, Main News

Check out drag racer and ProCalc customer, Bill Ketterman in his car The Widowmaker from September 1. His very high output methanol engine has a lot of compression, huge blower size and overdrive, and runs a low percentage of nitro. What a phenomenal run!

If you've got a run you want to share with us, we might even publish it on our site! Send it over and tell us about it.

We have a new weather provider!

By Jennifer on September 3rd, 2018 in Main News, Site News

Over the last several months, we've gotten reports of weather stations used on our site not updating very frequently. It was as frustrating for us as for our users. But, hopefully, all that is in the past. Over the weekend we implemented a new weather provider that seems to be much more reliable.

Our new weather provider will also enable us to add a few new weather features. They will be announced here when they are ready to launch.

Thanks to Bob Beck #46!

By Jennifer on August 13th, 2018 in Features, Main News

Check out Alan Beck #4, Bob Beck's son, storming around the Tom Manning Memorial race in their 360 engine powered Gun Slingers Winged Sprint Car at the 'Noceti family' Stockton 99 Speedway on June 6, 2018.

We recently had a discussion with one of our ProTune customers, Bob Beck #46 regarding his use of our site. Check out his thoughts on his experience:

Regarding fuel mixtures for Co. Nat. Spdway and Stockton races:

  • for the 360 engine; I used the program you have set for the 360 and ran the entire show; 7/6-7/18 at Co. and the Stockton show without having to adjust fuel mixture.
  • For the 410 engine used the program for the 410 and had to adjust mixture on all days raced. At Stockton it got so rich I didn’t bother with the HS bypass and went directly to the main jet.
  • I have concluded that some thing is not correct in 410 program: I believe it is the pump flow; 4.07.
  • I back tracked main jet change to pump flow of 4.56 +-.
  • I have sent pump to be flowed (subsequent flow test, 4.9 GPM).
  • I never new before how critical fuel mixture could be.
  • In years past I would be walking all over cars in warmups but later in the evening I could hardly keep up to the same cars.
  • What an eye opening this is.

Thank you so much to Bob for sharing his thoughts and experiences!
