2007 Cobalt SS - TVS - ZZP Stg 3 Cams - Dyno
just seems odd that he only dynoed at 350 with all of his hard work.

2.9 TVS pulley (20-21 psi by 8000 rpm)
10.6 AFR
21* total timing @ 8000 rpm
6k was around 18 degrees if I recall
It's clearly evident power is still climbing past 8k
shop temps were 95-100 degrees and it's on a 2.5-2" ZZP corked catback
3" exhaust and downpipe will go on this coming weekend with a revamped PCV/EVAC
I'm taking the efficiency route with this entire build rather than slapping the smallest pulley.
Powerband is massive, and is manageable.

There's always the option to slap my 2.6 on and a water methanol kit; but I honestly wanted to avoid a 25-26 psi setup.
I'd make substantially more power with a wet shot and only 20 psi.
Not sure if anyone on here can do this with their LSJ yet; but once you build it... ring it out to 9500.... the blower/engine sounds nucking futs
2nd gear ended at 100mph lol

I raced a srt4 that dynoed 420whp in steves car while it was at my house.
I beat him with less hp but steves car makes so much power under the curve and the ability to rev to 10,000 rpm makes the car stupid fast and way less shifting.
I let off at 130mph in 3rd still had plenty more

3" exhaust is going to help this car a bunch. It is just asking to breathe, not choke! Pushing for 400whp off bottle will be a fun challenge, but I think it can be done with enough tinkering. Get the exhaust flowing, then lean it out back to the low-mid 11's or wherever its happy and then push the timing a bit. I lost a decent amount of power on my TVS setup and turbo setup as soon as the AFR dropped into the high 10's. Next time out, shoot for the fences!

We'll know this weekend after install/tuning/racing/tinkering session
