FYI, we saw a solid .3 gain just by switching to alcohol on the old motor

Wow!!! That would put us in the C Gas class we have been going for since 2005.... LOL

.3 on a 5 second car is amazing..... Shit if we went .3 we would be in the 5.80's.. Cool

that car was a 5.60 car and went consistent 5.30s after switching to alcohol. that being said, i don't know how well the carb was tuned on the race fuel. i just saw the time slips. one thing i do like about the alcohol is that its not as finicky when it comes to weather changes. i didn't make a single change last race and temperature and humidity changed quite a bit when the sun went down.

Even on Sunoco standard once the jetting was and plugs good I left it alone. We run at pretty much the same DA every time.

DA will drop by nearly1000' late in the evening here. last race in Denton was 3400' at noon and 2600' at 5 pm. i stopped recording at 5 because thats when the rocker broke. it got better later in the evening. humidity changes pretty drastically throughout the day too.

Well the car ran great in 105+ temp and 138* track temp. Last runs at 9.85 and 9.75 lifting at 1000' Nick is sending in for his licence with runs signed for.
Last pass at 138* track temp was 6.04 at 111.99 mph..... Hell that could be a 9.50-9.60 run. People were coming by an saw the small block asking if it was a 434...... LOL nope 377".. Even the Chaplin at the race told me the car sounds pissed!! LOL
