Maybe you didn't listen to what the owner had to say..car would run well into the 9's with a bigger stall and exhaust..only thing this car has is a supercharger, 2800 stall and a cam designed for na..nothing else has been touched..

Can your car run a 10.08 at 138mph?

Stock motors on both.
From what I've read the di is holding them back a little right now. Can't get enough fuel to them.

It probably can, yea.

Probably do it with about 650 or so to the ground.

GM performance cars struggle to perform with the engine that came from the factory in them. Must use junkyard truck motors to go teh fastez..

Yep.. 2015+ 5.0s make similar to more horsepower on 12lbs with the twin kits than the GT350 example. They are handling 15psi range too.

5.0s are highly regarded boost motors

And that is going to be a common problem with DI setups. Ford will have the same issue when they go DI unless they introduce supplemental injector setups from OEM.

I've mentioned that also. Furd has some dual injector set ups already. It's gonna take that for tunability i think.

The turbo setups be a wee bit more efficient lb for lb. The coyotes are definitely holding some impressive power figures. Still 840rwhp of blower car that revs to 8k. I'd be smiling from ear to ear.

Yeah, but I think there is a reason why we haven't heard much else out of them about the car. The Voodoo is not meant for boost. I have no idea what Lethal was thinking. But its definitely something different.

Comparing boost from turbo's to blowers is not accurate at all. Twins will always make more power 10-12 psi is mid-high 600's on a coyote with a D1. The two motors make very similar power on boost with equal mods.

Lethal sucks. I think everyone was looking forward to an NA build with the gt350. But they just went to their old fail safe of "just throw a blower on it".

Forged Rods on bottom end. Heads flow more, intake flows pretty close to what the Boss intake flows with the exception of power past 7000rpm. It's fairly close to a Boss motor when it's all said and done.
