This was on a trailblazer v6 converter and using hptuners vcm controls to hold the car in 3rd gear lol. I swapped to a billet fti piece now. I can actually make boost on the footbrake now. My car also has a drag pack other than that, everything is 100% stock.

If that was just 15#, that's definitely a 9 second combo if it was turned up a little. I would say it probably even is with your new converter. Really good to see this thing performing.

I'm confident with this new converter it'll go 9s. My 60' is holding me back. I've made a lot of 60mph roll races with my friends sc'd, cammed ls3 Vette that runs 9.9 and I walk off from him at 60 mph.

Was that with the 5.7 ls1 or 5.3, 4.8?
M6 or a4, what gear? Great numbers.

Thats amazing. I would love to boost my stock ls1, and 15psi would be awesome.

Any ARP studs used?

Really looking at purchasing the On3 or the VS racing version of these turbos for my build. Good to see these things running well on the heavier cars on pump gas tunes. I have a Mercury Zephyr and I am sure it will weigh a little over 3000lbs once completed.

I will be using a 6.0 with 5.3 heads. Really looking forward to getting the car up and running, but have a lot of work ahead.

When I bought the car a valve was bent and I actually reused the stock tty bolts...if the weather holds I'll be going to the track again this weekend on 17-18 psi.

tucn26, thank you for posting your results. Many of us have been waiting for real world testing with this turbo, it's fantastic that it works so well with such a mild setup. Can't wait to hear results with a couple more psi and a better converter.

Stock cammed LS1? Whats your suspension consist of? Did I miss that?

My suspension is 100% Stock. Only mod I've done is pull the front sway bar off. I've got some pictures of good launches using the force 3rd gear trick and lifting the wheels. It also broke my damn dash when I launched I'm also running a modded version of he cx racing ac kit.

The LS1 is stock internally as well (sorry if I missed it somewhere)? If so, that's impressive.
