HP potential on a built 346ci What sort of HP potential could I expect if I had a built 346ci LS1 running 9.1:1 SCR with LS6 heads, blower cam and supporting mods (fuel, injectors, etc.)
I'd be running on 91 octane and would prefer not to use meth/snow kit.
1. D1SC Procharger
2. Front mount single turbo (TTI, GMR Speed kind of thing)
3. STS
Would any of these kits be able to supply 600-650rwhp for reliable street use on only 346ci?

And yeah I would mean using different pistons when going forged to lower the SCR down.

I was meaning would a Procharger or one of the budget turbo kits be able to supply this sort of HP detonation free and safe enough to use everyday on 91 octane. Or would I really be needing to look at a larger displacement motor to run this sort of HP?
I mean I really want to go FI, but for the cost I don't want to just run high 400 or 500rwhp. A stout h/c setup will make 440rwhp+ for a lot less money. But if I decide to go FI I want to know it will be able to make the numbers for my intended use.
If you go slightly lower CR and run more boost safely, I'd say you could make a SAFE 700 rwhp (stock cubes, big cc chambered heads, mild cam)... but that would be on 93. I don't know what 91 would do to that calculation.

And to answer the OPs question, yeah, pleanty of examples for your goals.
SC's and Turbo setups drive completely different. My blower setup had off idle power like it was NA. My turbo setup is like driving an evo... Ever driven a stock one? Does not make a lot of power down low and then takes off.
Honestly I'd go 8.5:1 for either setup, you can always have the tuner add timing down low to get the car to move but at peak power you want to make sure that your combo is not running too hot.

What do people think of the TTi stree turbo kit compared to the GMR Speed single?
Is one better than the other?

You would probably have a challenge getting 650 rwhp out of the street kit. Maybe if you upgraded to a good FMIC.

Never driven a centrifugal blower car though, but they are rare this side of the pond.
I do really like the Prochargers but by the time you get a FMIC and 8 rib belt pulley sorted and that the cost is probably more than some of the single turbo kits.
So I'm not really sure which route too look at. I really want to sart modding now ready for adding FI later on, but that means yes to LT's if I go Procharger but no to Lt's if I go turbo. I just don't want to keep buying things twice.
Think I've ruled out the STS, it may be cheap but spool up time and LAG are real concerns for the type of use the car will be used for.
I'd also like to keep the air con if possible. So I think I am leaning towards a Procharger, I would just hate to get back from the dyno though and think should have gone turbo. Even more so if it wouldn't have cost any more overall.
I know it's a difficult question, but assuming running 8.5:1 SCR correct fueling and supporting mods, what sort of HP variation do you think there would be between a D1Sc Procharger and something like the TTi street kit with a t76 turbo? Lets say running 93 octane and tuned for street use. I know the turbo should make more mid range lb ft and HP but what about PEAK?

I'd really be looking for something which doesn't require loads of fabbing or alterations and keeps the a/c. Oh yeah and doesn't cost the same as a house, lol.
BOSS APPROVED!

D1SC will accomplish this hp range all day long.

I plan to sell my TTi kit. I think if you are looking for about 500 rwhp, or are new to FI, then it is a good way to start.
I like the OFI kit, and turbozone also has a kit that keeps a/c.

BUT single log on one side? WAY too much heat and choke on one side for me... If you go single, I suggest you avoid these...
In other words, look at what 700+ rwhp single kits are being run and notice what configuration they are... Then decide if you really want a log style for a single turbo on a V8 (Which run well BTW around ~600, I'll admit).
