Hey guys well i have an 89 240sx with LS1 with a built A4 and 3800 stall.
I have ran constant 6.9's @103mph on a 75 shot with 4.09 gears, LS6 manifold and ported throttle THATS IT not even headers.
Well now i have 3.55 gears, 130-140 shot and the car was dyno tuned and made 493 WHP and 520 trq even doe it spun the tires on the dyno. Im wondering if i will hit my mid 10 second mark I'm aiming for, sense the car might be making a bit more. Let me know what you guys think. Thank you.
and if you have any tips I would highly appreciate it.
