I'm playing with some ideas of putting on a S/C sometime this year but I want to keep it on low boost (for now :devil:)
I drive the car everyday, so I still want it to be reliable. So my question is, what kind of supercharger would be best for me? Also, what kind of numbers would I be looking at with full bolt ons, heads/cam, and the S/C?
Any info would be great, and if you guys have any links to somebody who sells what I need that would help too, so I could price it out.
Thanks a lot :thumbup:
You could run a Procharger and keep it under 8# on a stock block.
Tuning and enough fuel is the key.
Or you could run a Vortech V-9 G-trim with aftercooler, stock block, etc...( and GOOD tune )
what is the diff between the two?
I went with the Procharger because I didn't want my cut my SS hood, or drill the oil pan and have the top of the engine in-accessible.
so the procharger will fit under the stock hood?
Yes. I think the Vortech will also.
where'd you get the procharger and what numbers should i expect?
I bought mine from Bob @ EPP. Stock engine should get you about 425-450 rwhp.
i mean with full bolt ons/heads and cam.
also one more question, I'm kinda getting worried because I'm getting my exhaust done right now, got QTP LT headers, and right now they're putting on a 2.5" X pipe over the axle. Originally I wanted 3" but he said he couldn't fit it, so we had to do 2.5". Will this restrict me later on down the road?
I know it will be fine for me right now, but if I end up pushing like 550-600 HP will I need to change the 2.5" and put in a 3"?
Oh, you should be over 500 rwhp.
Are you doing duals?
yes it's a 2.5" x pipe with qtp LT's
You should be fine on the exhaust. I have 666 rwhp pushing through a single 3"
oh wow really? that's good to hear.. i was just told by somebody else on the site that it will only be good for around 500 HP :thinkin:
by the way, thx for all the help too!
so you already have heads/cam package on your car then?
nope not yet but will be coming soon, early this year.

nah i won't be doing it all at once, it would take me a maybe 4-5 months to get the money together for the s/c, and I would like to do heads/cam asap. I'll be happy with a strong 450 hp car for now lol :)
oh but while we're talking.. what do you think I should do first, fast 90/nw throttle body or heads/cam?
how safe is it to run boost on a stock block? And would 500HP be acheivable with a procharger and H/C on a stock block?
Also...for a procharger...how do you not have to tap the oil pan? Do you have to tap the block?
well i know w/ full bolt ons and a good head/cam setup you can get around 450, so I'd imagine you would be what.. 600+?
Prochargers oil is self contained therefore you don't need to use engine oil.Quote:

If you are going to keep a stock bottom end, heads and cam are a waste of money if you are buying a S/C. Good exhaust, methanol, and 9psi will make over 500rwhp with an M6 and stock H/C.
You need to set your goals before you throw parts and money at it. A cheap set of LS6 stock heads and LS6 cam will net you about 575rwhp @ 8psi with meth and an M6, and 9psi will make close to 600 with this setup. This is a bit more than than most suggest for a stock bottom end.
REALLY REALLY do your homework though, don't dismiss the hidden costs of FI: 60lb injectors, new fuel pump and hotwire kit, meth system, clutch, driveshaft, rear end fairly soon, be ready to add fans knowing that cooling may take some work, 2bar tuning, etc.
i guess that my goal is somewhere around 450 rwhp...Im thinking about doing the LS6 head swap and a medium cam and headers and exhaust...hopefully that will help me reach my goal
Hmm, even on low boost I would have to build the bottom end?
Also, why would heads/cam be a waste of money if going with a S/C?
Because, they cost thousands of dollars Vs. a couple hundred for pulleys... make the power with boost, that's what it is there for. No you don't have to build your bottom end, 9psi and meth is WAAYYYY cheaper than 6psi and H/C, and drives better too.Quote:

Maybe my best route would just be a good heads/cam package for now..
If you have the money. Go Blower. And skip the heads and cam for now.
So according to this site..
http://www.exoticperformanceplus.com...l?category=186
D1SC procharger with injectors, fuel pump, balancer, pinning kit, and tune for $6,820.
Is that all I need? I already have the LS7 clutch so as far as that goes it should be able to handle the power, and I know I'll probably have to do the rear end.. But what else is necessary?
My friend has his old D1SC procharger (he changed it for a F1 on his vette).. it needs to be rebuilt, something broke on it, but it only has like 10-15k miles on it)
Anyway, he said he would sell it to me for $1,000.. I don't know how much they'll charge to rebuild it, but it can't be too much..
It's real tempting, how reliable do you think it will be if I keep the boost low?
ATI setups are very reliable once the little things are worked out. They are asily reliable enough to daily drive. I am saying that it is safe to make about 500-550rwhp on your stock bottom end, though there are always exceptions on both sides. Use meth; it's cheap, a little goes a LONG way, and it is protection.
Well that's good to hear... It would be my daily driver and that was my main concern--reliability.
what is meth?
methanol injection cools your intake tract, allows you to run more timing, and acts like a high octane fuel. It only comes on under boost and supplements your existing fuel. It adds a safety net if used right to help prevent knock and high IATs to keep your stock motor together.
You have a LOT of reading to do; this is expensive, and you want to know most of the gotchas before getting into it.
Just take your time and build your setup right the first time. Believe me, there are plenty of people out there that just "jump" in and forget to think this whole thing thru. Before you know it, a lot of broken parts and lots of lost cash later they wish they had built their system right. If it's your daily driver then I'd remember one thing. Once you start adding power adders to your car you have to give up some reliability and longevity. I don't expect my motor to last 100K miles and I have to be willing to keep putting money into it. You build a high HP motor then your drivetrain becomes the weak link.
You've picked an expensive hobby.....and addicting one....you'll get 500hp then you'll want 600, 700, 800.......it's a drug.....lol
Oh ok I thought that's what you meant, just didn't know what it did. Anyway, thanks a lot for all the info and advice, I guess I'll look into this some more and try to learn as much as I can and then pick my route from there.Quote:
