I didn't think you needed to enhance these TT systems? I thought APS got 640rwhp on a stock engine, which seems like more than enough to push it to its edge?
Anyway, I'll be curious to see how you make out, and what you actually push it to on a stock motor. Good luck and
on the FI upgrade.

I'm actually really curious to see what just the TT kit will do on the stock motor with maybe a meth system included for some added protection and power, but at the same time, the gearhead in me wants to just go for broke. It's a conundrum.

installed a few sets, they make decent power, it's cheaper than AFR, but doesn't make as much power

Fastbird ...
This kit will make the max power limit for a stock motor. As I look at this kit's components ..... we will only need to upgrade our fuel supply, clutch, and add an EBC to allow us to finetune boost.
Nice thing about FI ... we don't have to spend more on intake or heads ... to get the 600-650 HP needed to max out a stock block. Just turn up the boost a tad to press the air in alittle quicker and @ denser conc.
Personally I like the punch of high compression. No reason to reduce it, and then have to turn up the boost even more.

As we all should know, as VE of a FI motor increase, boost will decrease as boost is a measure of restriction. So theoretically, on an AFR head/custom turbo cammed motor, 7-8 PSI would be something more like 10-12 PSI on a stock motor, which I wouldn't be comfortable doing. Does that make any sense (I'm in my own little world here).
Another reason for doing this, is I have every intention of having a forged shortblock built anyway. Getting the up front cost of a top end package out of the way would go a long way and give people a chance at seeing what the APS package can do on a stock shortblock with additional supporting mods as from what I can tell, most guys will simply be putting these on a stock motor.

I think that you are right on. I'll be running my 205s with a mild cam. This should be a great combination.
I realize that the kit is more than capable of maxing out the stock shortblock by turning up the boost some, but my end goal is to get more airflow in a more safe manner. I'm looking at it in the light that a set of AFR heads with larger combustion chambers will help to lower the compresion ratio a tad allowing a "buffer" on the boost/squeeze area (with me keeping it at 7-8 PSI) while flowing a tremendously larger amount of air than the stock LS1 heads.

On a side note, what do most people feel is the max boost and RWHP that can be fairly safely run on a completely stock LS1?

Question really is what is the cylinder pressure. This is the key to engine longevity.
I'm not argueing about changing heads/pistons to reduce C.R. That would lower cylinder pressure for sure and help. I'm saying that just changing intake / T.B. is not gonna help engine or turbo survivability. It may only allow you to make X amount of HP ... at a slighly lower A.B. boost pressure. So .... spending money on new T.B. and intake will have a low benefit : to cost yield for you.
As Peter (APS) says .... if you want to go much over 600 HP .... just 'forge away' and jack boost up to double digits.
Spend your money where it will make the biggest difference .... FUEL upgrades, TIRES, CLUTCH, and perhaps DTE bracing.

Instead of spending the money for AFR heads, custom cam and more on the top end just to do a forged lower later, why not just do a forged lower now, and add some used (in good condition) LS6 heads and cam, turn up the boost to get whatever horsepower you want, and be done with it?
I just "cleaned out the exhaust" on the car for a few miles, good old bolt on 340 RWHP 345 RWTQ setup. That kind of made my decision for me. I'm going to just do the turbo kit with a methanol injection kit for now, along with some new valve springs. That should put me over 500 RWHP safely and will allow me something to look forward to in the future while saving me a ton of cash at the same time (moving halfway across the country in 2 1/2 months).
Thanks for the advice everyone.

eh too bad you're moving. I'd like to see the setup and work done. I was even going to offer to help if needed.
If you start this before you move let me know I'll be an extra set of hands to hold the beer.

I'm having it installed actually. I won't be doing any wrenching myself, which is unusual, but an opportunity presented itself that I couldn't pass up. There is a definite possibility that it'll be completed just before I move so you may get to have a look. I'll keep ya posted.
