The Placerville outlaw sprint car event was a hit. Thousands of people sat all around the track to watch the closest racing ever. A lot of photo closeups were taken of $50K fuel injection engines in the 410 and midget classes. Men & women drivers from all over were putting on very fast competition. The food was great.
UpDate: due to rain on Fri, Team Broddie was rescheduled to run through Sun Mar 26. The Saturday event was great. ProMod horsepower was apparent. A couple blown alcohol setups; my favorite, were there as well. A large crowd of racing enthusiasts gathered to join the fun. An atmosphere in the air of fun & racing competition!
Team Boddie‘s promod drag race is scheduled this weekend, Fri Mar 24 & Sat Mar 25, at Sacramento Raceway. Email us if you will be there, and we’ll look you up. The show will be filled with grudge racing, high horsepower drag cars. The crowd is always enthusiastic at this event. A lot of charm and excitment.
Mechanical fuel injection is holding its own against EFI and racing carbs in racing. It is simple, lower cost in many applications, and good for fuel pressure increases for more response & power. One recent application tested racing carbs, EFI, and mechanical fuel injection all on the same racing engine. Another recent application tested mechanical fuel injection against racing carbs in a factory developed combination. In both applications, mechanical fuel injection was good for about 5% more horsepower. Fuel pressure is limited in common EFI racing packages. Reduced flow from the venturi’s is a limit in carbs.
This year’s Sacramento AutoRama is a hit. Several new custom cars were on display along with several updated regulars. Various fuel injection setups were displayed. Mechanical fuel injection on autos and boats were my favorite. Check in with the Sacramento Autorama Feb. 17-19. Again, email us at email@example.com if you are attending. We’ll look you up and take pictures.
We will again be at the Sacramento Autorama Feb. 17-19. Email us at firstname.lastname@example.org if you are attending. We’ll look you up and take pictures. This is quite an annual event in the Sacramento, Ca area with a lot of different hot rods.
We are working on a new tuning package for our fuel injection jetting calculator, ProCalc. We can set up ProCalc specific to your combination. If you have a flow bench test, dynamometer setup, or prior runs, we can transfer that to ProCalc. We are matching brake specific fuel consumption, air to fuel ratio, and other fuel injection characteristics. ProCalc jetting baselines are developed to take your engine to any air density or elevation with optimum jetting extrapolated from your baseline using fuel injection jetting science.
We are finding solutions to all kinds of problems with current setups from flow bench errors, dynamometer test errors, and problems from less than optimum run results from the track. Fuel pressure too low or too high, mixture too rich or too lean, uncalibrated dynamometers that explain a loss of performance between the dyno and the race track, shortcomings in flow bench recommendations, and many others. This package will be available through dealers as well. More information is coming. Email me at email@example.com for more info or call California, USA 916-419-6649.
I have enjoyed reading through your “High Horsepower Tuning for Mechanical Fuel Injection”. Very nicely done! Bob, it is nice to see how thoroughly you do your books… all the details and examples of how things work are just great.
Thanks for your very nice “Special Thanks” at the front of your book, and for mentioning us by name through the book.
Recently we’ve gotten some positive feedback we wanted to share:
“Thank You for the prompt reply and formulas you provided, now onward…….. Just want to tell you how much your books helped me in the tuning area. The reading was technical but interesting and informative. I found myself reading each chapter twice before moving on to the next as it flows chapter to chapter. Now I understand why and how the different aspects fit together and can make better calls and decisions. The 5000 Horse Power On Methonol book goes with me to the track so if need to, I can use the
formula’s and figure it out long hand on paper. Looking forward to positive results.”
“Do any of your books touch on the use of the Pete Jackson blown alcohol barrel valves? … Bob got your books they are outstanding!!”
