The truck in my sig has run 12.3/112 with a 50hp nitrous shot in hot/humid a$$ed weather. Runs 12.6 without the gas. MP122 blower and 2.8" pulley makes about 7.5 psi. I've seen 8.5+ psi in cooler weather. Previous runs were made in 85 to 90 degree heat. Assume a crisp 40 degree evening. What's it capable of ET and speed wise?

 

Go run it when it gets that cold & see.
I wonder if 11.9-12.0 would be doable?

 

That's going to happen. Just wondering if anyone has maybe a program that could project power vs temp vs qtr mile times. I've seen programs that will give you ET's based on weight and rwhp. Just wonder if there is one that takes temperature into account.

 

yeah a pound or better and a few tenths off your time with no other changes easy.

 

I thought it was 1% bump in power for every 10* ambient drop. So, if I did my goes-intos correctly, that's how I arrived at my guessimate.
