This link though, he had to adjust his camber to increase his contact patch. what I'm referring to is leaving everything else the same (including camber and the vehicle weight and passenger weight, tire pressure, ambient air, weather, etc.) a wider tire on the correct width wheel will increase contact patch |

I’m with olehead. So many variations that can affect a run. As an example I put down some of my runs made on different tire and rim combinations. The different combos end up with different tire diameters adding yet another variable.
My fastest 60’ times came on the stock 225 Cinturato. Who would have figured? They have also produced some of the quickest ¼ mile times. This is just a sample of runs, but without a doubt the TSW with MPSS 245’s has been consistently slower by a couple tenths in the quarter and slightly slower in the 60’. OP, if your main goal is just to get in the 11’s, put in race gas and should get there with the current setup. I’m still of the opinion that root cause you need to look at the tune. A PS2 should be giving you much better trap speed.

All of that is only a small piece of drag launches - there is all kinds of fancy physics around the way the wrinkling tire sidewall stores and then releases energy, along with leverage and altered diameter (and all the weight-transfer factors). Not sure how much of this applies to a road tire like an MPSS, but it is what drag radials are designed for. If you want to drop times, I'd consider some dedicated wheels/tires for sure. |

you need 20-30 more hp to get you into the 11s.
Fuel, run some 2gal of ms109. Add a jb+, it will work and is good for 30whp or .2 in the 1/4mi but not everyone likes to double dip tunes. loose weight, remove everything from the car you can. I ran my 11s on oem wheels and stock runflat all seasons.
