Impressive, through mufflers no less. I'm going LG big 3 over the winter with my front mount turbo setup from straight duel 3 inch to the bumper.... I'm also thinking about doing a 3 inch boost activated dump set at 10 lbs with the big 3... I'm looking to quietly break hearts. Lol.

It's getting quicker and faster all the time. Better air? Better tuning? Better driving? Combination of all three?

Very impressive man, congrats!

Your t56 is from rpm? I guess level 6? And the c6z rear is a stock one or rebuilt? Do you have a lot of passes on that drivetrain hows it holding up?

The trans and diff are bone stock takeouts from a C6Z.

At least 200 passes on it.

RXT clutch and bias ply tires. FTW.

What size pulley on the YSI? How much boost and power are you making? I'm building a forged 347 and switching to a YSI this winter so I'm curious

2.7" pulley. Hasn't been on the dyno in this configuration.

The MAP sensor is maxed out. Maybe 25lbs or so.

This is on E85.

What kind of launch? Slipping it out? 2 step? And other launch control assistance? Always impressed with fast a stick cars.

2-step. Launching at between 4200-4700 depending on conditions.

The clutch pedal adjustable stop from ECS is an important part of it.

I need to get my car to leave like that. What is your shock, suspension setup? I installed Viking da shocks but only got 3 passes before end of year, northern Illinois weather. Looking to concentrate on everything to launch the car next year. Which 2 step do you run? Lpe or msd . Is that still a 17" wheel?

We did have better air, but it was windy and the track conditions weren't as good as MIR. The crew at Atco did a great job trying to maintain the track, but they were fighting the cold temps and wind. The tune was the same.

Thanks. The C6Z drivetrain is a great setup from GM

My suspension is all stock. Shocks, bushings etc. The front swaybar is removed.
My rear wheels are 16x10 Bogart's with 28-11.50-16 QTPs.
I have been using the MSD 2 step and a clutch pedal stop.

Amazing driving, congrats!

Question-what was the best time with the stock mn12 tranny? What improvement did you see with the t-56? Wondering what impact the gearing had with your et.

Thanks
