TUNING THE DAY BEFORE

Wednesday, October 28th, 2009

The racer is one step closer to setting up a tuning plan for density altitude like we wrote about throughout our technical manuals; the racer can log onto www.airdensityonline.com and get current air density and density altitude for many race sites throughout the US; (more…)

5000 HP?

Wednesday, October 28th, 2009

Dyno results just in from one of our customers on his new twin turbocharged alcohol Big Block: dyno’d 2,500+ HP at 25 psi boost with a turbo setup capable of 50 psi boost. He reports that the most boost that he is currently seeing in the installation is 35 psi, blowing the tires away on the drag racecar.

BRACKET RACE TUNING BLOWN FI THE DAY BEFORE

Saturday, June 20th, 2009

In our drag racing, we did use air to fuel ratio as a controlled value to get the engine into a linear range. That task is an extensive explanation through out writings. The linear range is where the engine is completely predictable. We achieved that very well in our racing. (more…)

O2 Sensors

Saturday, June 20th, 2009

QUESTION: Do any of your books help in areas of tuning with using O2 sensors? I am needing some what of a baseline for a good tuneup using the correct nozzles, pills to help with getting the most or should I say most consistent in drag race ET’s. Of course everything being the same.

Thanks for replying, R. in Texas

Hi R in Texas,
Thanks for your inquiry. Our Jetting for Racing Mechanical Fuel Injection … book has info on O2 sensors including accuracy limits.

REPEATABILITY VS ACCURACY: O2 sensors are a great tool, however, the accuracy (especially for methanol or ethanol) and repeatability may be issues. Accuracy is less of an issue if they are repeatable. (more…)

METHANOL PURITY?

Friday, April 17th, 2009

Question: What is pure methanol?
Answer: If it is sold as pure methanol, it is supposed to be well over 99% methanol. It is a baseline compound that should behave the same regardless of supplier unless it is mixed with something else such as a top end lube or it is contaminated. (more…)

METHANOL STORAGE

Tuesday, March 24th, 2009

Question: Can methanol be stored for a long period of time?
Answer: Methanol absorbs moisture. So if it is stored, it must be in a sealed container. Plastic is microscopically porous and does allow for methanol moisture contamination if it is stored a long time or (in some cases) if the container is dipped in an ice water bath to keep it cool on a hot day.
