Pretty excited to get my Colt in to the 13's last night: 13.924@101.95 mph 2.333 60' The car: 4G61t/stock motor/act 2600/walbro255/14b@15psi/1G mas/1G smic/1G ecu/450 inj/93 octane/street tires. Dropped the front tire pressure down to 25psi and the car grabbed 2nd gear with no spin, felt really strong after that with max knock count @ 7 in 4th gear. |

Nice, work on the 60' and get that knock out. Maybe add some race gas next time and turn the boost up? |

What RPM were you shifting at or aiming for? |

I switch back and forth from 6500 to about 6900 on the shift points, there are so many variables which makes this car inconsistent that I'm still not sure what is going on. I'm having troubles getting MMCd to upload to my computer, or else I'd have shift points and other info to share on that 13.9 run. I took the racing gas advise and got Sunoco 104 unleaded. Turned to boost up a half turn which equaled 19-20psi. Ran a best of 13.625 @ 106.69 mph 2.453 60' with a 2 knock count max, thanks!

Nice mph, I couldn't ever get very good launches when I was FWD, best I could do is 2.1 with some DR's. Best I ever got on street tires was 2.3 but most of the time it was 2.4. You've got really nice mph though! I still have those DR's if you want them for cheap.

Nice work man congrats that's a 12 second car for sure. try turning the boost down a few psi or switch to a dual stage MBC run 10psi off the line switch to your 18psi in mid second gear. Work on rolling into it off the line if your spinning. another thing you could try letting the clutch out a little when your staged with the e break up holding the release button in then drop the e brake and roll into the gas pedal on the third amber just before green. good luck don't roast your clutch by letting it out for to long on the pre load. |
