Ran my car again last night and managed to knock a couple tenths of a second per lap during practise before the quals.

Last week the car was running in the 12.1 to 12.5 range. Last night I ran some back to back 12.0's and then near the end of my run it happened. I turned a 11.9 and then an 11.8. This was with little to no traffic on the track so I could really get into a groove. Once the quals started I lost the mojo and was back to 12.3 or 12.4 second laps. Then in the main I gained back some lost ground and got it back to 12.1

I was adjusting the boost on my Tekin RS all night to find a happy medium. 45 degrees boost worked good in practise but was a handful in the quals. I ended up running 25 degrees boost on 13.5 turn and it felt fast but controllable on our smallish 72x45 carpet track.

Here is the setup that I ran:

Front:
56 x 6 piston, 27.5 wt oil, green spring, 3mm spacer, bladders cut
middle arm, middle tower
1-A link (2mm on bulkhead, no limiters on block)
1mm bumpsteer
no toe in/out
-1.5 camber
22 mm ride height
spindle washers flippped (1.5 top, 0.5 bottom)
25 degree kick up, 5 degree castor

Rear:
55 x 6 piston, 32.5 wt oil, pink spring, 0 limiters, bladders cut
inside arm, middle tower
2-C link (2mm bulkhead, 1mm on hub)
hubs moved 1mm forward
3.5 toe, HRC block, 2.5 degree antisquat
22.5 mm ride height
-1 camber

Minipin rears, stagger rib fronts
Tekin RS w/ Duo 2 13.5
Xcelorin 3800mah 96mm lipo
Savox 1258

21 grams on rear gearbox. No weight under battery.

I notice with the bladders cut and running emulsion shocks the car takes a few laps before it feels its groove. My lap times generally go down 4 or 5 tenths after I have at least 4 or 5 laps on the track during practise. I try to pump the shocks by hand before I put the car down for the quals but having the shocks work in on the track seems the best.

Who is running bladders still vs. running emulsion style?
