I'd be interested to know what your burb weighs with you in it. I'm guessing 5600lbs+. If you hit the high 12s it's going to take a bit more HP.

I'm sure it's fast, especially for the size, but you can't stop physics.

I hope I'm wrong and it kills into the 12s.

I'll be sure to post numbers after I have it dialed in on the dyno and make some passes at Rockingham Dragway in NC. The engine itself is around 550-560 at the crank, which is considerably more hp than the LS3, Gen 1 Coyote, and 392 Hemi. It'll also depend on the driver too if i'm against a manual.

Had dual 3" exhaust installed last week with an x-pipe and 2 Carven R mufflers, with the exit behind the passenger rear tire. Still loud, but fairly quiet inside.

Wired up my fuel composition sensor Friday night, and had it dyno tuned Saturday morning. It laid down 402 hp and 418 ft/lbs torque at the rear wheels. Definitely happy with that considering it was 95⁰F plus and my IAT's were over 130⁰F. She rips for what it is!

I am also now going a different route from the LSA TVS1900 I was originally planning. I will be installing a Whipple 2.9 for a 2010-2015 Camaro SS, which will run cooler at the same boost levels, and will let me keep my a/c compressor where it is. It'll be a while before I collect all the parts for it, but I can't wait!

Lord willing, I'm going to try to make it to an 1/8th mile track this Friday and put some times down.

I finally made it to test and tune without it being cancelled due to rain. My best time in the 1/8th mile was a 8.85 with a 1.999 60' which was quicker than the 3 5.0 Coyote Mustangs that were running tonight (8.90s-9.20s).

I entered into a dial-in bracket race, but lost first round due to it launching in 2nd gear and going into limp mode. I was stalling it to 3200 with my Lingenfelter box and I guess the pcm didn't like the rpm with no speed from the vss. Cleared the code and it did fine the next couple passes after letting it cool off. Now I know for next time LOL.

Thankfully nothing broke and it made it home safely! Huge win in my book!

I would imagine you were cutting a much better 60' than they were.

That 1/8th mile time computes to a 14.07 @ 97.83mph in the 1/4. Which in my opinion, is still moving for a giant hulk.

Did you happen to weigh it at the track?

The one mustang I ran did a 2.38 60'

I still need to make it to a 1/4 mile track and see how it does. I'd love to break into the 13's, but we'll see. Thankfully it hooks going around the water box!

They didn't have scales there that I knew of.

If it doesn't get into the 13's, this should help!

I have a goal of getting the Suburban to 8.50 in the 1/8th mile before I install my Whipple blower. Here is an 8.70 pass slip with a 1.92 60'. Plans are to do a little weight reduction and go down to a 28"-29" tire to change my effective gear ratio. I can also find better tires for those diameters vs the 31.5" I am currently running.

I am collecting parts to do the Astro knuckle swap with GMT900 front brakes. This should help prevent pushing through the brakes when I'm staging.
