75mm compressor and at or just under 2k lbs but no active traction features I'm guessing 8.551 @ a lot.

Our current estimate is 2470-2530#. We'll have a race weight in 2 weeks.

Is that estimate with or without Calvin in the seat?

Low number is with Calvin. High number is the fat driver behind the wheel. 

That LS and trans must weigh a lot more than I thought it would!

The trans is ridiculously heavy

Must be! Even with an SFI spec cage we're getting the 6cyl down around 2100lbs with driver and adding weight bars to get it to competition weight (2400).

The FWD trans is extra heavy because it has a diff in it.  I'm going to guess the ET and trap will be 10.11 @370 MPH.

370?

Aaah. No.

I don't know where on the track a 370 mph car that only runs 10.11 finally hooks up, but I want to watch it happen. 

Everybody's been discussing how the ET and trap speeds can get skewed using FWD.  So I'm guessing the car will take 4.11 seconds to 60 feet, then run the rest in 6 flat.  Hence the rather high trap speed.  My first guess was 380 but I thought that was too much of an exaggeration.  

Word on the street says that the Nelson family has officially entered the Challenge. Link to enter.

Thank you and looking forward to seeing this one in person. 

Its good to see this pop up when when I open GRM!

Neat build with great information. Check out the first dyno run.

I hope I can be there to see it run!
