If Im correct I believe that jayrash engine is supercharged ? or is the one with bmw body throttle ?

my first attempt was at 3200 feet of altitude and 91 pump gas

40 dcoe originally came with 28mm chokes, I replaced with max size of 36mm, 36mm x 6 = 216mm, I dont know the conversion rate but is more air than original 70mm body throttle ( I don remember the exact size)

I believe that I have a lot of room for improvement, but fisrt time was great, of course with cold box, 100 octane fuel , and more timing I will achieve better results, but rules says pump gas.

I believe that my timing curve is conservative, but engine runs cool and Im happy

lambda gauge say that I'm a little rich but spark plugs looks great
at this moment I use 50, 200, 110 f11 weber setup

at this 7 days rally exist diferent stage, every day exist a speed stage, but this stage max speed range is from about 70mph or less with a lot of curves, then I need all the torque. from 4000 to 6000 rpm
