Awsome quick runs and not even pushing it 100%. Those front wheels look like the Weld Aluma Stars, what size are they. I was told by Weld they would`nt be good to use on our cars cause of weight.

Yep, they're the one piece Alumastars. 15x3.5 w/ 2.25"BS, I was trying to tuck the fronts in a little more than before, thus the 2.25 BS. The Stange spindles moved them in just a hair as well.

I wanted the weigh the car as well yesterday, but the scales weren't on.

It doesn't see much if any street duty anymore, so i'm not too worried about them. I do have a full set of prostars for street warfare

Those are actually DERTY's wheels. They are the first set of 15" Beadloc's that Weld has made bling bling

they are 15x10 w/ 5" BS, 28x10.5W tire

I've got a normal set of Aluma Stars in the same size, but haven't mounted any tires on them yet. Still haven't convinced myself to drill holes in them for screws

For boost control i'm running CO2 on dual port wastegates. 3psi springs in the gates and direct connection from each turbo to the bottom port on each gate. Then fixed pressure to the top port to raise and lower the boost. I've got all the bits to allow me to roll the boost in after the launch, but haven't got it all setup yet. So i took it easy on the launches.

They said they would be there. I thought they were gonna run with you guys at Norwalk, but guess they didn't get the time off. See you at NPR.

I'm pretty sure it's a regular old LS1 block. It's unbelievable what these aluminum blocks are holding power wise.

Yep, a cleaned up LS1 block and forged internals. Top that off with a well managed Stock PCM and guess what... you don't need to go F.A.S.T when all you want to do is just go FAST.

LOL @ Dan

Never be in a mag, they don't like black cars

Still a .010 over LS6 block, stock crank and main caps. Good pistons and rods is about all. Nothing real special in the short block. Standard ARP studs and GM MLS gaskets, no O-rings.

6.0L heads worked over by Livernois Motorsports. These heads flow better w/ a 2.020 intake valve than my old heads did with a 2.020 valve or 2.050 valve (had both in them at different points). We also went to a severe temperature 11/32" exhaust valve to keep from melting/bending them like the last heads The change in mid lift flow from my old heads was pretty amazing, upwards of 30 CFM in some places.

good fuel, a "lazy" tune, and right around 20psi. Atleast the glances I got of the boost gauge. My datalogs from the runs should have a more accurate pressure number.

oh yeah, and a new intake manifold
