Nice set up. I see the 100 octane there. I left out alot of details on my opening post that I didnt think of until now.
Has anyone done it on 93 octane with a stock displacement engine with no help from nitrous?
The reason I ask is i am building my truck for a daily driver. I never plan to run race gas in it. I would love to hit over 500rwhp on pump gas.

Crash, do you have any dyno numbers on pump gas?

I've run an 11.95 @ 110.79 on my 5.3 with 3.1" pulley on the RADIX, pushing about 7.5psi. Keep in mind this is through an 80e, 4.10's and 27" tires. With 3.73 or even 3.42's and/or a bigger tire, I should trap considerably higher.

Raceweight was 4550.

I fully expect to make 500/500 by years end, even through a 4l80e and a 14bolt 10.5" rear end
