I dynoed again today and stil can't get to that 400/500 benchmark that I want to achieve.
I instaleld the 6# pulley and elctric fan last weekend and was looking forward to dynoing again to get to the 400/500 barrier, unfortunately I fell short
I'm sending a chip in for reburn to get the AF leaned out a bit to get it around 12.5-13 all the way across the RPM range. I am running very fat from 4300 on at a 11:1 AF ratio.
I have heard differing opinions on what is safe. I have always heard 12.5:1 is a very safe tune and 13:1 is an aggressive race tune for a force induction car.
In another thread JJ's SVT said that the L is safe at 14:1....it just seems scary to me, just don't wanna blow it up running it lean like that....any opinions ?
Here's are my charts....hope I can get the 400/500 when I get back in town next month ina little cooler air and a new burn.
BTW-It was 95* on the dyno and my mods are Intake w/90mm MAF,exhaust,6 # pulley,single blade TB,electric fan and chip
