I had a 2300 Maggie and THPSI, Rotofab and running on E65. I did have a JMS to help out my low side but did it with a Stock Lt1 motor and Trans. My best 1/8 mile at Gateway was 6.34@112 and 9.80@142.96, (707 rwhp/660Tq) 60ft times were not good with the A10 like my 16ss with the A8. I may have seen your Zl1 at Gateway. Went back and looked at some time slips from April at Gateway. On 9.8 lbs of boost and 677 rwhp I ran 6.50@109 and a 6.47@110 both with 1.45 60ft times, that was on my 98mm pulley, my 95mm makes 10.5 to 11 psi. At LS Fest last year we ran 10.34@135 and had a 6.70@106 w/1.50 60ft, that was on 8 psi and the car made 632/555 rwhp/tq.

I was only at Worldwide Technology Raceway (yeah, I still call it Gateway too) once this year in mid-July on a test n tune night.
Honestly, I'm really not a fan of 1/4 mile racing, everything I've broken (since the 1990's) has been 1/4 mile. IMO, 1/8 mile is way easier on the car, takes out (most of) the sandbagging in bracket racing, is safer, and the same experience. I'm fortunate to be within a couple of hours of several 1/8-mile tracks that have good programs.
Anyway, I appreciate your input, but port injection mods are not in the equation for me.
