dont take this as a noob question
but i want a ton of power, i want excess, i want 700whp
everything i own is this way and i want the car that way.

i have come to the conclusion that a high hp all motor setup is just too expensive, so im feeling the water on a forced induction setup.
so what do i need to get me there

i have the reg bolt on stuff
i am in the process of acquiring a 383 forged rotating assembly but im guessing it goes a little more in depth that that.
are there specific pistons i will need or a diferent stoke and bore than what ive been looking for
how much boost, and what type of heads?
can i just port and polish stock heads?
if no then what am i looking at for aftermarket heads?

what size and type of supercharger will get me in the area? they all have specs with max hp numbers but are those accurate?

how much and what needs to be done with the ignition system?

ive got alot done to the suspension already and i know ill need to get a new rear end and bigger clutch

i have a roll cage going in (6pt) and some sfc's


ive done the search and havnt found anything for a 600 plus hp setup, ive found a few things hear and there but i need to start cracking down and finding out what the limitations are of what i have and what my bank account will allow.

and def. feel free to ask me anything, i will be honest because i need honest answeres to make my car run write and the way i want it to.

 

Since you said "a high hp all motor setup is just too expensive", you might be in for a suprise as to how expensive a boosted setup is. Typically, boost is more expensive, but also more street friendly. The cheaper alternative is nitrous.

700rwhp, you're looking at a 8.5:1 383 with just as good if not better parts as a NA setup capable of that kind of power (remember that the crank is under a lot more stress to drive the supercharger), ported/polished heads (preferably aftermarket), long tubes, intercooled T-trim or D1SC, 75lb/hr or more injectors, complete new fuel system, good spark (coil per cylinder ignition preferred)...

And then tack on a few thousand for other stuff and weak links you'll break from having that much power.

$10,000 would be a low estimate, probably using a lot of used parts.

 

Hope you have enough coin to buy a nice used car or truck to do this, because it will cost that to do this endeavor. You can forget using any of the stock drivetrain or suspension parts.

I looked into this last year... here's some things i jotted down on paper:
Forged low compression 355 or 383 shortblock ($3500)
Stock heads WELL-ported by Lloyd Elliot (best deal you'll find at around $1000)
Cam with turbo-specific grind, and good valvetrain parts (~$1000)
Turbo or supercharger kit, with a good inter- or aftercooler ($4-5000)
Fuel and ignition systems (fuel management system such as FAST or BS3, lines, fittings, injectors, pump(s), wiring, coil(s), LTCC, etc... budget at least $2000)
Since you have an M6, get it worked with some viper parts and get a street twin clutch (~$2-2500)
12-bolt or 9" rear (~$2000)
Driveshaft, Denny's Nitrous Ready is said to be good, look into good U-joints ($700?)
Cage or roll-bar (varies, $500 minimum)
Suspension upgrades (shocks, springs, LCAs, PH, torque arm... $1500)
Brake upgrades (varies)
Tuning on the dyno (another good bit)
Shipping for these parts
And add another 2-3000 for contigency reasons (little things that will nickle and dime you to death)
So about $20k invested.

Some of your concerns:
Ported stock LT1 heads have hit 1000rwhp in turbo LT1s at around 23 psi, haven't heard much about stock heads and superchargers above 700rwhp, although i know a T-trim or D1SC will hit that high. Plan on about 16-18psi of boost to reach the 700rwhp level.

Eagle makes a good 4340 rotating assembly, any top-brand piston will do, not sure if hellfire rings are necessary but may be a good idea, and you may need to look into cometic (sp?) head gaskets for that much boost. It will be quite expensive to do this.

Some people i suggest getting to know on this board are rskrause, INTMD8, sleeperZ28, IDOXLR8, BigRick, JeffB94Z, and a few others.... all are above the 7-800rwhp level with boosted LT1s. Member "JZ 97 SS 1500" (Jose) knows his stuff, runs Forced Inductions and has built a few very impressive LT1s with the PTK turbo kit... one surpassed the 1000rwhp level with a 355 LT1, M6, ported stock heads, and a single T-76 GTS turbo.

Good luck

 

You kinda gotten clued in already. Never think 700rwhp and "inexpensive" in the same thought. The least expensive way is with nitrous. A blower shortblock for nitrous, high hp FI, and one for high NA hp are going to cost the same. What you save on the heads for the NA setup go into the blower on a SC or turbo car. A nitrous system will save a couple of thousand max over the others. Whatever the budget to make the hp is, multiply by 2-2.5 for the supporting components and the stuff you didn't think of. What you do get with a mega-hp FI or nitrous setup is much improved streetability compared to NA.

You also don't save much DIY. Most of the motor costs are in parts, the machine work and assembly aren't terribly expensive. Ditto for the other upgrades needed. I can give you a simple 700rwhp "recipe" if you want it. Do you?

When I researched this myself I figured 10K as I was parting out my 396. Rich wasn't lying to me or you when the number jumped a lot higher. My setup is a is hitting the 20K mark easy. If you do your fuel system right that alone will set you back 2-2.5K alone. Speed costs money. Only weak link in my entire setup is my rear as it's stock only w/ the TA cover and T2R diff but it handles 440rwhp all day since I don't get on it from a dig. That's not what I do. But now I'm looking at a 9" so tack on another 2.5K.

Even if you find the parts in the FS section you'll still past 12K IMO. Hope your pockets are deep and your cabinets are stocked w/ ramen because if not it's slim pickens to reach that number on a limited budget.

 

well the pockets are deep but not as deep as i want. im single and i make really good money.... time is the only concern but i own 3 other vehicles so its not like this is my daily driver
i would just like to do it within 2 years

i already have the suspension taken care of
the roll cage is in
i own z06 brakes

the only prob is i want the power and am looking for the most reliable and most streetable way to get it
money, well its always good to save money.

so thats prob my way of thinking as of today now that i keep doing my research.

is a turbo a better way of getting the high hp numbers or a SC?

i expected to spend quite a bit on the car so im just looking for something that will be best for me and you all know your stuff so i totally value your input.

and trust me i did expect to spend a ton of money in nickle and dime stuff. ive done one NA to Turbo motor before and know how quickly money and parts can build up.

im looking into a 383 rotating assembly for pretty cheap off the FS section on camaroz28.com

my next question here is, when looking into a supercharger what is it im trying to find out, what system is best for power? the numbers i need to know like max hp or max boost wich is more important?

i have a friend that is a distributor for Fast engine management systems and can get it to me for cheap

so thats what i would be working with for a computer

the bigger prob would be wht heads to get and how to figure out what cam i would be getting...

anything else anyone can think of please let me know, or if you have any suggestions or comments... i will be here reading and asking many many questions. thanks for the time

i was looking at an aeromotive fuel system, what do you guys think of those?

one more thing, for ignition systems what is something i should be looking into i found the direct hits system on here but it didnt seem like it would be enough.....

 

Considering that you're only looking for 700hp, you might want to stick with a centrifugal supercharger; which has less complex plumbing than a turbocharger. Turbos are for people who want crazy power. You merely want silly power.

My advice to you is to FIRST decide if you want to go Vortech or ATI. They have some different ideas on how to get things done and you want to figure out whose propaganda sounds more compelling. You can also do a search on this subject to locate the opinions of others who are already using these products.


The bottom end and head are the easiest parts in the sense that the bottom end is going to follow the same basic recipe for either brand and every head vendor/porter has a particular design that will get the job done. All you have to do is tell them: "700hp please" and they will tell you which parts you need.

The same is true on the supercharger end actually. Just tell that what your goal is and they'll tell you which head unit you need.


I'm building a centrifugally supercharged 357 LTx with 3.48 stroke and 6" rods, but I'll be running alcohol. If I were going to be running gas, I'd go the other way; with 3.75 stroke and 5.7" rods.

In the end, if you can keep your costs under 10 grand, you'll be doing well.
Believe it or not, it's not the big parts that kill you, it's the little things that nickle & dime you to death.


By the way, if you're REALLY smart you'll take Rich's 700hp recipe. It'll save you a ton of time agonizing over parts and you get the benefit of his often expensive experience.

 

By the way...
Forget max boost or max power.
You want to look for a head unit with good adiabatic efficiency in the range you will be using it.
Start looking at compressor maps.

 

ok any pointers on what im supposed to be looking at on the compressor maps

i know what they look like but have no idea how or what im reading on them.

 

i have a 396 for sale with some top of the line heads

pm me if interested

This is a page I have bookmarked on the subject.

 

There are many available choices for some of these parts, but what I am posting is what I KNOW works. The question being answered is "what are the basic parts needed for a reliable, streetable 700rwhp LT1 combo at the least cost". What I'm describing uses a centrifugal blower, a turbo certainly could also be used, but I don't know as much about them.

block bored not more than 30 over
4-bolt main caps
Crank: Lunati Sledgehammer or Callies Dragonslayer
Rods: Lunati Pro-Mod
Pistons: JE "blower" pistons
Rings - Hellfire not a bad idea
AFR 195cc head plus porting - the CR should end up in the 8:1 range
GM LT4 intake, port matched
58mm TB
Vortech YS trim or Procharger F1, custom hard intake pipe needed
Intercooler - variety of choices including none if water injection is used
Low impedance injector converter from Acceleronics
~90lb/h injectors
255lph intank pump
Kenne Bell "Boost-a-Pump" or equivalent
adjustable FPR possibly needed as a tuning aid
"blower" cam grind with ~220-230 degree intake duration and supporting components to match
good set of headers
custom dyno tuning of stock PCM
good ignition amplifier - variety of choices
nice cold plugs

Probably forgot stuff, I'm sure you guys will catch that.

thanks for the info....
everyone

now i need to keep up with this research

there is so much involved
i kind of like the challange
