StageX Questions
A few more questions about your StageX TTi setup:
1.) Is everything after the turbo manifolds on your car (and back to the exhaust) factory pipe?
2.) Are you running cats or no cats?
3.) Are all four O2 sensors in tact (e.g., no O2 sims)?
4.) Where's your wideband O2 mounted, and is it mounted all the time?
Thanks

Exhaust is Bassani X pipe with B&B Prt's and not Cats.
Front O2's are in place and the rears are gone. Your tuner will turn them off when he tunes it
, no need for sims.Wide band is mounted all the time, I feed the analog output from the unit right into the Blitz boost controller.

I put a deposit on the TTi kit earlier today. George at TTi said that the manifolds are at the foundry and are arriving later this week (they've completely sold the first batch of kits and are nearly sold out on the second batch, only 1 more kit left after my order). He has some machining to do and then they are shipping the kit. So barring any unforeseen complications the TT kit should be on my doorstep in about 3 weeks.
Install sounds really simple. We'll see when I get it though. Should make for a fun winter project. When I asked George how difficult it was, he said really simple. I told him I installed my LG headers and he said it's as easy or easier than that.
I'll probably run 9-10psi max and most likely run 6-7psi on the street. I am hoping that 6-7psi is 550-600rwhp on my stroker and 9-10psi is 650-700rwhp. Those numbers are a little optimistic but I did make 600rwhp on 10psi of supercharged boost and I would guess that I should get back at least 50hp without the parasitic blower loss -- but who knows. I admire RoadRebel's dedication to R&D of this kit but I really don't feel like grenading differentials on the dyno so if the numbers are a bit lower, I'll still be happy

If the install looks too complicated I'll call up Mike @ Next Level Performance / Norris Motorsports. They've done a few turbo cars before with great results.

I think more HP at the same boost level is not going to happen (just my opinion though, like you said - you never know for sure until you do it)
You will see more TQ and at lower RPMs for sure and the opportunity for more HP is a given if you are willing to turn it up. Did you go with the dual BB turbos. What springs are going to be in the waste gates?
What is your static compression on that motor?

Later I will leak some new info on Kit warranty

I have an LG Header setup right now and do not have the factory pipes anymore. How will the downpipes from the turbos bolt up to my LG setup? I'd like to keep my giant Random Tech Metal Matrix cats and the 3" piping that goes all the way back to the exhaust.Does the downpipe clamp onto the turbo or bolt onto it?
Here's a pic of the stock pipes (taken from www.ls1howto.com):
And a pic of the LGs:
As you can see, the header itself goes much further back than the stock headers do. Any thoughts?

What size is out exit side of the downpipe? They look somewhere between 2 inches and 3 inches. Since the downpipe points straight to the back of the car (instead of having that funny twist to it) I can use my existing pipes. But depending on the downpipe size I might have to figure out a create way to increase pipe size from the downpipe to the cats/xpipe.
IMO, I would sell the LG setup complete. You will recover more money overall... and will not require you to spend money adapting an LG 3" setup that will not buy you extra power.
We sell Stainless Works and TPIS header packages that have Random Tech cats and X-Pipes. The TTi kit (at least the Stage1) dumps in the same location as the headers. Judging by what I see on Phil's car George has not changed the dump location. I believe the Random Tech kit that adapts to the TPIS headers is the one we use on the Stage1 Turbo kits. It only requires the collector end of the cat pipe be opened up slightly to slip over the down pipe. Its been awhile since we installed a Stage1 kit with this Random Tech setup but I believe this information to be accurate. Random Tech also makes an "offroad" catless setup for the same 2 header manu's that would easily adapt. We use Accuseal clamps for a tight seal that will help prevent pipe movement... which in turn requires much less, if any, exhaust tip realignment.
If anything, the guys at Random Tech seem to be really easy to work with. Hell, if I get another install anytime soon, and the customer is willing to allow a week or so of pipe fitment, we can append a complete intermediate pipe assembly to the TTi kits that requires no welding.

Mind if I give you a call tomorrow to talk over this? I see that Random has a part number 752720 that is a 2 3/4" pipe setup with dual cats. I think this is the one you're talking about.
Do you sell it?

Congrats on your new kit. 383 + TT's = Freaky fast.
