Just thought I'd post up my time slip on 93 pump gas (no alky). This was on 255/60 BFG Radial TA street tires, not known for hooking. I'm going to try running again on pump gas soon, but this time on my new street tires, 275/60 Nitto 555Rs. This run was on 6/30 of this year.
60ft.........2.005
1/8..........7.919
mph.........90.72
1/4.........12.241
mph........113.59
With alky and a little more boost, I was able to get some 1.9 60fts out of the BFG TAs. The Nitto 555Rs are pretty decent street tires and last for a decent amount of mileage. They aren't near as good as something like the Mickey Thompson DRs, but I actually got some decent 60fts on them (I got a lot of 1.7s and even a 1.6 60ft) on my alky tune. Now that I've got my pump gas tune at 20lbs of boost in the good weather, I'm hoping to get something like a 11.7@117mph on the Nittos on pump gas (no alky).
As far as tuning on pump gas, I'm using the same TT alky chip. I took out all of the first gear fuel through the chip and maxed out the WOT fuel (on a dual nozzle alky tune I normally leave the WOT fuel correction near 0 so I essentially added 20% WOT fuel for pump gas only). My car doesn't like high timing at all, even with alky or some race gas thrown in. I pulled out timing so that I'm running 18 degrees in 1/2 and 17 degrees in 3rd gear. I normally run 21/19 timing on alky. Anymore than this and I start to see some knock up top. I've run a best of 11.0@121mph on pump gas and alky at 24lbs boost.
Here is the combo:
.30 over 109
Champion heads and matched intake.
206/206 roller Comp cam and roller lifters.
CPT61 BB turbo
rjc boost controller
3" THDP
Big Mouth cold air kit, 3" MAF with MAF translator
CAS V4 stretched stock location intercooler
RJC power plate
63lb injectors
Walbro 340 "hotwired" fuel pump
TA ceramic coated headers
ATR dual 3" exhaust
TH400 with manual valve body, hipster tbrake, TCI streetfighter converter
B&M Quicksilver shifter
EGT gauge and Directscan for tuning
Savitske springs front and rear, Bilstein shocks all around
Boxed stock lower control arms, stock uppers
Energy Suspension bushings in upper and lower control arms
Stock 8.5" rear with 30 spline Eaton posi and Moser axles
HRparts rear swaybar, no front swaybar
Centerline Convo Pro wheels, 15x7 up front, 15x8.5 out back
Bob Bailey 2step (didn't have this yet on the timeslip above though)
.
I'm sure there is some stuff I forgot to mention.
