Default 6.0 with LSA Dyno Results

Numbers are in. Max effort pull peaked at 588/521.

we backed timing out a little bit and settled at 565/505.

Very happy with how controlled and stable the car feels, and the power delivery is insane.

Engine setup (for anyone who missed it)

6.0 (9.6:1)
LS3 heads
LS9 cam
stock upper/lower pulley
T56
3.55 rear end

8psi on 93oct.

Impressive. A cam swap would pick up too along with more boost

Good numbers but I'm kind of surprised the torque line isn't more flat than that.
I have an almost identical setup in my S10.
Mine is an LSA supercharged LY6 (6.0 with LS3 Heads) 9.6:1 LS9 Cam and TR6060 close ratio trans 3.42 gear E85 fuel.

It looks like it carries pretty good. The problem is the HP and TQ are on different scales.

Yeah, that wierd scale for the torque makes it look all kinds of jacked up. Until you realise the entire scale is only 50 ft lbs top to bottom. Wonder why they did that, much more useful if they are on the same scale.

Zl1 or Caddy lid? any port work to blower or T/B? What exhaust and what type of HX/coolant pump? ( sorry, putting together an LSA topped build myself so just curious LOL)

That probably feels great in the little fox, but I think it's time to pulley down and add a flex fuel sensor :-D

zl1 lid
no port work
1 3/4 stainless headers to 2.5” catback
factory zl1 heat exchanger with a Bosch intercooler pump.

Car already feels stupid. I don’t think I need any more power...for now lol.

Those are awesome results! If you ever wanted to gain some HP, I'd wonder if there could be some to be had swapping to a 1 7.8th header and 3" exhaust.

I’m sure there would be, but it probably wouldn’t be worth the cost and time involved to swap everything IMO
