FAST90mm + QTP HVM LT's = *The Real Deal* Finalized Numbers
Old: 425/387 (LS6/SLP LT's/3" True Duals X dumped)
New: 458/403 (FAST90/QTP HVM/QTP ORY + SLP 2OTL)
Same Dyno. Same internals. Mother of All Bolt Ons Swap.
More info to follow.
Edit: Dyno sheet attached (458 was thru open cutouts - closed shown)... though not a direct back to back X to Y comparo (due to the other mods swapped), I hope this makes people realize that properly made Y-pipes put down the numbers.

85mm lid, 85mm maf
1 3/4" QTP's
Cutouts only gained 1rwhp. The QTP ORY and the 2OTL flow like a ****.
I'm picking up the dyno info tomorrow, along with the car.

wow thats impressive i need to put mine on the dyno and see the difference of my cutout and SLP dual dual which supposedly flows alright
ok i was under the impression that you had the 1 7/8 headers with those collectors
sounds like you got a strong car there, do you happen to know the a/f and timing they put in there?

Best part is it takes all the attention of the extra money you spent on the intake

Awesome results man! I need to talk you into trying out a MiniStick camshaft in place of that 231.237

Thanks all!
A few notes:
This heads/cam combo has really woken up with this final round of bolt-ons.
Before, the TSP231/237 really pulled hard up top (as it should). I ran it cam-only at first, then with the TEA 1.5's. The addition of the heads bumped peak hp from 390 to 425, but the H/C combo still lacked low end, yet pulled like mad up top.
With the addition of the 85mm/90mm intake tract, and the HVMC LT's the engine now responds VERY STRONGLY across the ENTIRE rev range. It's like a new animal all together.
While this thread features the virtues of the FAST90/QTP HVM LT's bolt-ons, I must commend TSP and TEA for the kick *** nature of their internals. The ol', lazy 231/237 grind (one of the largest grinds available at the time) and these intro/budget heads (recommended to my by Brian from TEA when I was shopping around over a year ago, as I couldn't afford their Stage 2.5 LS6 heads) really perform.
I'll post up the graphs as soon as I can.
By the way, not only was this the same dyno, it was same tuner. I was told today that this car pulled the highest NA Heads/Cam 346ci numbers yet at Kelley Chevrolet (South Florida is not exactly Texas or Michigan when it comes to strong LS1 engine setups). And it's well known around these parts that their dyno is far from liberal.

Wow, I'm impressed! Don't think 123 mph trap speed in decent air will be a problem (assuming decent traction too). I've hit 122.9 with 438 rwhp at Moroso. I don't recall from your previous posts, did you port your intake? I want to install mine but haven't figured out what I should do about porting the intake.
