Hello well just after resetting up my engine yesterday and was racing all day today the engine ran excellent for the first time in ages getting 12 mins a tank so easily making the 10 min efra ruled heats without piting, 5 heats where ran today all of which i feel i did very well pushed hard and was rewarded, after 10 mins engine temps ranged from 112c to 121c

my question is tomorrow if i keep up the work the A final is 1hour long, should i richen my engine slighlty bought 1/8 high end

or will the tempeture it reaches after 10mins remian the same until 1 hour of flat out running is it the max/optimum temp it will reach?
if you understand what im asking.


thanks adam

You were 144f - 153f for the fahrenheit guys and those are good temps. If it aint broke don't fix it. Take a temp test during your pit if it needs it richen it then, oherwise run the hell out of it.

personally I run the main harder than the quals. I richen my engine up 1/2 hour before the main. But if you drive the same in all races, I would leave it alone.

100C = 212F - Boiling point on both scales, so 112C has to be over 212F. Actually, 112C is 233.6F, 121C is 249.8F.

Conversion C to F = degC * (9/5) + 32

The temps look good btw, but for a full hr main, I'd richen just slightly too.

Are you saying 1/4 of a turn? or 1/4 of an hour. Big. Big difference..

Naw, when you say 1/4 turn, I think 3 hours. So when I richen it up 1/2 hour, that means that I turn the HSN open just a "smidge".
