You aint seen nothin' yet. I have 200# I could drop off this truck in a day and My converter is killing me. I think it would go 10.80-10.90 with those changes, and 10.70-10.80 with the right (275 pro as opposed to the 315 pro) tire. Also, slightly more boost is on the horizon... 17-18psi vs the 16-17 that it was at on this pass.

I been trying to get to 9.99 all summer but 10 .477 was the best I can do this year belt slip and traction problems is stopping me from my goal so it will be under the knife this winter .. I ran 20 lbs of boost on my 408 ci built motor with a 125 shot of nitrous on this run ...as for heads Texas speed stage 3 ,pro comp cam 240/241 590/591 -114..pulleys 8 rib 3.0 on super charger and 10% crank pulley shifting my FLT level 7 4l65E at 6500 rpm with converter going into full lock at 80 mph.

Interesting cam choice with 20psi and nitrous.
I assume you are having traction issues? I think you’re at the point where he 65e is hurting you to be honest. You can’t use al the power off the line, and the gear ratios are a wider ratio than the 80e. I ran a better 60’ in my 05 denali with a 370 running 16psi boost only with an 80e. The rest of my pass was nowhere near as fast as yours because I wasn’t making as much power.
What does your exhaust look like? I ask because 20psi sounds high as well for a 408.
I am not trying to be critical so please do not take it that way. I would love to see you make a 9 second pass so I am trying to understand more and potentially offer up some advice.

Sorry ,not 100% on cam no# it's the 3 cam my motor builder installed this year...my TVS2300 S/C is 10% overdriven also ,I run 17/8"long tube headers with 3" duels all the way back with a Xpipe...my 4l65e trans is being sent back to FLT for a gear upgrade 2.84 - 1.55 close ratio gearset should give me 2/3 more tenths in the 1/4 ..plus going to upgrade to a new 10 rib pulley system. THAT should get me closer to my goal.
