Round 1 mods included a Vararam Intake, Solo Performance Axleback's, and a dyno tune for 335 rwhp and 346 rwtq.
For round 2 I went with American Racing Headers 1-7/8" long tube headers with catted x-pipe and an SLP underdrive crank pulley, along with a dyno tune. The tuning was done with the car in 4th gear and then the final pull was done in 3rd to keep the numbers consistent with my previous numbers.
Round 1 vs Round 2 dyno graph, both pulls in 3rd gear:
And if anyone is interested, here's the 4th gear pull:
My last trip to the track with just the cold air, axleback, and dyno tune had me running 13.17 @ 106 mph with a 2.04 60'. The car never spun, I would just do a small burnout, bring the rpm up to just over 1000, and mash the gas.
I went to LVD last night with hopes of coming home with a 12.99 timeslip. I was also hoping that the extra power would be enough to get me a 1.99 60'.
According to dragtimes.com the DA was between 1800 and 1200 last night.
First pass in I ran a 12.82 @ 108.4 mph with a 1.98 60', but I forgot to hold the trans in 3rd gear and it was in the middle of shifting into 4th as I was crossing the line. For the rest of the runs I held it in 3rd.
The runs went as follows:
12.75 @ 110.04 with a 1.959 60'
12.749 @ 109.96 with a 1.958 60'
12.713 @ 110.19 with a 1.956 60'
12.715 @ 110.71 with a 1.970 60'
Overall I couldn't be more pleased with the car as I easily hit and passed my goals for it. I might take it back later in the year and see if I can improve on the numbers in better air, but as far as mods go I think I'm done until my Z28 is back on the road.
