I think both Andrew and GVP are partially right.  Andrew is right that a great chassis will make an average motor look good but if you are in a big race like the R/4 or Fall Brawl you better have a great motor if you want to make the A main.  Likewise GVP is right in that you have to have at least a great motor if you hope to do well, a great chassis and a average motor just won't cut it in a big race.

 

And here's a fact of physics, the coefficient of static friction (i.e. not sliding) is greater than the coefficient of dynamic friction (i.e. sliding) so a car that is hooked up perfectly will come off of a turn and accelerate quicker than one that has a slight slide out of the turn even with identical motors.  I've seen that the cars that have virtually no slide in a turn (in fact they look like they have a second guide!) come out of the turns like a rocket and pull me a foot or two after the finger even though our motors are even down the straight.

 

And let's not forget driving ability, here's a quick personal example.  I was practicing my GT-12 on a tight flat track in NorCal and after a whole morning of testing and tweaking I had gotten my car to a time of 3.000 sec and felt nobody could go quicker with my car.  It just so happened that Paul Gawronski was practicing next to me and confident that I had gotten the last .001 sec out of the car I asked him to take a few laps with it.  After just two laps he had already taken .150 sec off of my best time, lesson learned!

 

Bottom line is that you need both a great chassis and a great motor, not to mention exceptional driving skill, to win the "Big One".

This post belongs in the Joke of the Day. LMAO

 
Maybe you should take up cornholing as your next hobby. Danny Zona and I can walk you through it. No motors, no electricity, just a bag of corn and your highly-skilled throwing arm.
 
Same one you used to bang your motor shaft at the SANO which got you banned for a year from IRRA®.
 
Or if you don't like that advice, come on over to my "Pablo" forum and explain which of my building techniques you recently referred to as "BS." This is my second request, by the way.
 
Maybe the root of your problem getting power to the ground and getting beat by stock motors is your use and promotion of wavy piano wire which most sane and skilled builders commonly discard.
 
You started the war, GVP, I'm just helping others see the facts.   :laugh2:
