Motivational Engineering Wins The Street Car Super Nationals 

Mike Saiki and the crew did it again by winning the Limited Street class at the 2009 Street Car Super Nationals. Mike was able to hold off the competition with a new personal best  ET  of 8.48 @ 164.55 mph. My hats off to these guys for all there hard work. I can't wait to see what they do next year!!!!



  Motivational Engineering

Motivational's  1968 SS Camaro running stock suspension with 28x10.5 slicks. It weighs 3520 lbs. This class requires a 4150 based carb and intake set up so we turned to Bryce of Dr. J's Performance to discuss our needs.  Bryce was able to take care of our needs and provide the porting of our  Brodix BB4 heads,  Brodix 4150 style intake and build us a Holley 4150 based HP carb. The motor is only 525 cubic inches and made 870 horsepower on a conservative dyno.  There is a single stage plate nitrous system by Steve Johnson of Induction Soultions and a Mike's mike_siaki_carbtransmissions powerglide and 10 inch Continential converter. It has a Ford 9 inch with 3.73 gears.
    Going into the final race of the season in the WCHRA (West Coast Hot Rod) Limited 10.5 class I was behind 56 points. This meant that I needed the current points leader to lose in the semi finals and I needed to set the ET record, MPH record and win the event. A lot to accomplish but I wanted the championship real bad.  The current records were 8.67 and 160.7MPH.  The first tune up went 8.87 @ 161.8MPH ! Happy with the way things looked I played with timing and at the end of qualifying I had set the new MPH record of 164.32MPH in the 104 degree heat also. For Eliminations we decided it was best to soften the car up and delay the hit of the nitrous by .2 to go for the ET record. 1st round we ran a 8.68 @ 163.3MPH. 2nd round we ran an incredible 8.55 @ 163.93 MPH ! We now had a window of 8.46 - 8.66 to back up the record. I had a bye in the semi finals and the current points leader lost in his semi finals. The car I had to race just reset the ET record to 8.66 which meant I now had to go better than 8.66 and win the finals to get the championship. When we left the line I spun a little and he was out on me by 1 1/2 cars at half track but, I had the field covered by 6MPH. Using this I was able to run him down and win with a margin of victory of only .012. I ran a 8.65 @ 163.54MPH which was good enough to set the ET record and win the 2009 WCHRA Limited 10.5 championship.
    It has been an exciting season and we are glad to have been able to work with Bryce of Dr. J's Performance to get the performance we needed at the time we needed it the most. Thanks for all of the help and track support.
