Dynojet yes as seen in the background banner.
I experimented with slightly leaner and slightly richer AFR’s and this is what made the most power. Made over 25 pulls tonight after spending 4 hours dialing the car in from scratch. There isnt a spot in that fuel map I did not touch. Was doing some gas consumption testing as well.
AS CAST 243!!! No milling no porting just a set of patriot gold valve springs.
I have noticed our shitty “93” out here with 10-15% ethanol needs the slightly richer mix to make power now. In the past I have put literally 1 gallon of 100 in 8-9 gallons of pump gas but I did not do any tricks I wanted real results. I just use the good octane gas to counter affect the ethanol crap.
very good info here. i admire your honesty. :thumbup awesome numbers then and id love to see more real world results like this man! cant wait to learn a thing or 2 when u come to ny.
