Another 369sxe on the Dyno

Got on the dyno again yesterday with my new turbo. It's a 369sxe with a .91 t4, but I'm still on the ATS t3 manifold, using an adapter. I put down 770 and 1380 at 2800us, but think I lifted the head a little bit before that because I was puking a little bit of coolant out of the overflow. I made just shy of 700hp at 2375us, I'm in need of a gate and manifold real bad. I was seeing 80-100psi of drive pressure up top and about 55psi of boost.

I've attached some of the dyno sheets. I still need to do some investigating, as it's sealed up fine now, hasn't dumped doesn't get hot but definitely lost some coolant the last few pulls that I did. Could be the cap, and possible that after the engine was built the previous owner may not have done a retorque on the studs. We'll see.

Be interested to see what it does with a T4 manifold. Surprised drive pressure is that high.

Wow, excellent power numbers from that setup. We've been doing some more testing with the 369sxe and 366sxe on my Junker Drag Truck and we've had a couple mid 700 HP pulls as well. Both of those turbos make excellent power for their lag/spoolup.

Yea I'm pretty happy with it, once I get a proper manifold/gate and some real studs I hope to see 800 plus out of it.
