The GT35R turbo is really something special. On my little sohc 4 cyl it put down 569rwhp and 600rwtq at 35psi. That's with .82 ex housing and turbonetics log mani. I'm switching to a tubular header and 1.02 housing which should put me close to 650.
I can only imagine how sick the 35R would be on a vette, especially twins.
These damn TT deals have me thinking.......

The PTS, and others supporting 76's, offer alot of flexibility relative to where you want to make the power irregardless of cubes. If you're only looking at peak numbers they can all make 850rwhp. Beyond making it at lower boost, big cubes making 850rwhp with power dropping off at 5200rpm is fun on the street but doesn't really offer a performance advantage on a roll or at the track when compared to stock cubes making that same power. Stock cubes will be easier to control as it builds boost, easier on the drivetrain and, most importantly, pull harder past 6500rpm.
With all the bottom end power of big cubes the last thing you want to do is make it uncontrollable. Put a big set of turbo's and compliment the existing powerband by giving it the ability to pull harder and harder to redline. IMO, that's why the rearmounts excel.. but fronts w/ bigger turbos are the best of both worlds.

TTi's answer... it's better than big.. it's secret

There is a similar package(Boost Master) who has posted his #'s on the Corvette board at 14.5 to 15psi.. I think he makes right at 846rwhp/9XXrwtq on pump gas and meth. I dont even think we need the meth, but it is there for safety.. My car is pretty much identical except for a few things. He has a 402ci and I have a 408ci and his cam is very close to mine, but mine is one degree of advance bigger. He has cat's on and I dont.. The thing is we can turn up the boost even more, but the question is why? We dont have traction now. Once my tune is finalized I will post my low boost #'s.. Low boost will be around 13 to 14lbs. High boost will be 14.5lbs to 22lbs for me.. I totally expect the drivetrain to take a crap once I turn up the boost, but hopefully when I get home they will have better parts for the drivetrain by then....

With regards to needing anything more, I totally agree with the not needing anymore cause it takes major nads to use what it's capable of and deep pockets with regards to the drivetrain. I think we along w/ the great majority is in the same boat with being happy with what we have, but what's optimal for us isn't for necessarily optimal for absolutely everyone else. For those, the flexibility of tailoring how that power comes in without really going for any more power is... the key.

LOL.. my high boost is 12lbs and its more than I can even come close to using on the street.

Another thing is I opted for a smaller cam than what my tuner originally wanted to go with. That is another reason why my base boost is higher. If I would have went with what he wanted my base boost would drop 2 to 3lbs via the loss of restriction. I could just change the spring as well if I wanted, but I kind of like having to controll my foot

Some great info here guys, thanks
Vince, you stated that you have the biggest turbos that you can fit, but your sig says standard small turbos. Can you clarify?
So the turbo size with the TTiX kit are secret? Is that what I am reading?
Where can I find pics of this kit? The TTi website isn't working for me. or is it very similar to the LPE/Grantelli/APS and other low hung kits?

The jokes on them as there are multiple Vettes in the 9's with X kits.

I know the APS kit has twin 38's located where the cats were and are capable of 850rwhp on a 427.
Lets here some more
