I sold the 95mm LT5 and used a 103mm Katech instead.
We went with TSP LTs and a big gulp to keep air flowing.
With the provided 110mm pulley, it put down 670 through an A8 at 6psi.
I'd like to circle back once everything is broken in and bump that up to 10.

It has good street manners and surprisingly nice fuel economy on the highway. But I do want to add a pair of resonators to take care of the rasp at 1700rpm (ie: part-throttle acceleration, where it is most annoying). It's not likely to see the track or any formal street racing, but it does put a smile on my face I'm very happy with the way this turned out.

blk TB or Green TB would be killer!

Good idea.

I added the Borla 60608 resonator today. it made a huge difference in how smooth the car sounds and it's a lot more fun to drive now without the rasp.

We went ahead and deleted the AFM valves and crush pipes while we had it on the rack.

Looks good, make sure you put the passenger floor cover back on. It does help it stay quieter in the cabin. I actually added them to my LT1 since it was so loud inside.

Yes, it has been ordered. It got caught on debris on the interstate one night and I had to tear it off so I could get the car home.

Nice setup. Some spray detailer on the cowl area might get ya another 15whp.

LOL It did get a good detail after the work was done to take care of a few weeks of dust :p

Is the limitation here injector, or something else?

I have it in this week because I had two lifters fail.
I asked Justin to go ahead and upgrade to forged pistons while the block is out for repair anyway, even if only for peace of mind.
We can finally get the bumper, meth kit, 103mm snout and pulley done as well.
I feel like +30 injectors might not be a terrible idea at this stage if the fuel rail can handle the volume.

It looks like you already have a low side and LT4 HPFP.

If that's the case than yes the injectors are next.
