Not 100% sure 5-6? That is why the 2 step No multi tasking skills .2200 RPM @ 0 psi 100%+
slicks are 28-9X15 I was running 255-60X15 MTDR, It took 20 passes last year to get it to hook The Helwig bar was the ticket,The track prep in Hawaii is not so good.
Hoosier and Mickey Thompson both recommended the slicks to be more consistent for bracket racing
And the 2 step was added to help me be more consistent.
My Alky is set at 6 and I have not touched nothing on the PAC,no KR O2s 780 all the time ,I will order a wide band this week (AEM)
I will check the Alky turn on this week I think it is 10 psi
I had been running a TT 5.6 street chip adding 2.8*, I gained no MPH by adding more timing than that ,the O2s came down just a little 760-770s I was stuck at 111mph 12.1to 12.5 ET 1.8 to 1.9 60s one 11.93 ET with a 1.628 60FT 89.9 660ft 111 mph 1/4 (like to know how I pulled that out of the hat)
This year same tune but with a 2 step
Five pass the two best where
1.784 60ft 7.776 660 @89.56 mph 12.166 @ 111.19 2step 2800 no retard 5th pass
1.855 60ft 7.943 660 @89.19 mph 12.344 @ 110.98 2step 2700 no retard 3ed pass
I installed a TT ALKY chip locking the convertor @85 mph
First pass 1.802 60ft 7.651 660 @ 92.05mph 11.92 @114.1 2step 2800 no retard no timing change to chip 6th pass of the day
Second pass 1.723 60ft 7.586 660 @ 91.68mph 11.88 @113.5 2step 2800 8* retard no timing change to chip 7th pass of the day all passes at 24.5 lb boost (Turbosmart E street)
I think retarding the timing 8* on the 2 step bilt some heat my O2s were 664 @000 mph no KR on the second pass I have always been 780s at 75 mph +-2or3 mph
No data logger. Im staying in the 11.90 bracket class, I'm there just want it to run consistent ,I'm sure 11.5 is it with 42.5 injectors but my target ET was 11.90.
This car is a beast, spools fast and pulls like a small block on the street I leave it in drive to keep from hitting the limiter
